Shovel Self-loading concrete mixer trucks are widely used in special vehicles for hardening construction operations with narrow roads, such as residential buildings, rural road construction, squares, workshops, etc. This product has self-feeding, self-water supply, self-mixing, 270-degree left-right turn all-terrain large-angle cutting, high-pressure automatic tank flushing, and a multi-functional engineering mixer truck.

The temperature is high in summer and the physical energy consumption is large, which is a test for equipment and operators. Today, I will discuss with you what to pay attention to when using the truck mounted wet concrete spray machine trolley in high temperature weather or areas in summer.

Wet concrete spraying manipulator is a very suitable concrete spraying machine for large-scale concrete projects at present, which can effectively save human resources and construction time, especially for the places where manual spraying is difficult in tunnel projects, more and more concrete engineering projects have begun to use it.

Concrete shotcrete machine is a kind of shotcrete support equipment widely used in underground engineering, geotechnical engineering, municipal engineering and other fields. Concrete shotcrete machine is generally divided into two categories: concrete dry shotcrete machine (also known as dry shotcrete machine) and concrete wet shotcrete machine (also known as wet shotcrete machine). The concrete dry spraying machine is a method of mixing cement, sand and stones evenly in a dry state.

With the continuous development of tunnel construction technology, the requirements of tunnel engineering quality, operation safety, occupational health and other aspects have been continuously improved. In each process of tunnel construction, mechanized equipment has gradually been used instead of manual labor. Tunnel concrete wet spraying machine has become the mainstream of shotcrete operation. equipment.

Concrete wet spraying trolley is a kind of mechanical equipment widely used for concrete spraying support in traffic tunnels, hydraulic tunnels, mine roadways, underground workshops, military facilities and other projects.

Shotcrete machine is the core equipment in shotcrete construction, and is widely used in related shotcrete support projects such as construction, municipal administration, railway and highway tunnels, foundation pits, mines, and slopes.

Concrete shotcrete machine refers to the professional shotcrete support equipment that uses compressed air to form a suspended air flow of concrete in a certain proportion, and sprays it onto the surface to be applied to form a dense concrete layer to achieve the purpose of support.

Since the 1960s, western developed countries have begun to implement wet spray technology, and various wet spray machines have been developed and put into use one after another. At present, in some western countries, wet spraying machine has become the main equipment for shotcrete operation, and the application rate in many countries reaches more than 80%. In China, wet spraying technology started late, and the market was still blank until the early 1990s.

When installing the concrete delivery pump, the user needs to consider the source of the concrete. If it is commercial concrete, the mixer truck supplies the material, and the delivery pump can be installed on the spot, as long as it is convenient to feed and take over. If concrete is mixed on site, the location of the mixer needs to be determined according to the feeding method and site of the mixer.

Small concrete pump is a kind of industrial equipment commonly used by many construction units today, which can improve the efficiency of engineering construction. At the construction site, after the concrete pump truck is used for a period of time, the piston life of the concrete pump truck will be too short. So, how to solve the problem that the piston life of concrete pump truck is too short? In general, the factors that cause the piston life of small concrete pumps

Concrete boomr pump is a construction equipment that relies on pressure to transport concrete through pipelines. It combines the production of ready-mixed concrete with pumping construction, and uses a concrete mixer truck for intermediate operation, which can realize continuous pumping and pouring of concrete. It is equipped with special Concrete can be continuously transported horizontally and vertically along the pipeline. Concrete boom pumps are divided into various models,

Concrete construction engineering has received extensive attention in today's social development. The use of concrete delivery pumps provides support and assistance for concrete construction. This is an equipment project developed and produced by our company for many years. The following is the cleaning work of the concrete pump for your reference.

Concrete line pump is a kind of construction machinery. Because its working environment is relatively poor, it is more necessary to do daily maintenance and maintenance work. Among them, lubrication is a very important work. Concrete floor pumps are divided into manual lubrication and automatic lubrication. part, the specific analysis is as follows:

At present, a kind of mechanical equipment that many construction parties use a lot - a small concrete pump, which greatly improves the construction efficiency. If the pump driver does not operate properly in the project, it is easy to cause the pump to roll over, which is a problem that many construction parties are very concerned about. So, how can the small concrete pump truck prevent rollover?

1 Improper operation can easily lead to blockage of the pipe
1.1 The operator is inattentive
The operator of the transfer pump should concentrate on the pumping construction and always pay attention to the reading of the pumping pressure gauge. Once the reading of the pressure gauge suddenly increases, they should immediately reverse the pump for 2 to 3 strokes. . If the reverse pump has been carried out and the pump is being pumped for several operation cycles,

In the construction site, all kinds of machinery and equipment are overwhelmed, and the safe use of concrete placing boom machine machinery and equipment is particularly important.

Concrete pumps play the role of transporters in large-scale concrete projects such as high-rise buildings, highways, and overpasses, so they are very important. For concrete pumps, the correct and safe use is equally important. In the daily operation process, how should we use the concrete pump correctly?

The concrete pump cutting ring mainly cooperates with the rubber spring, and the gap is automatically compensated by the rubber spring and the pressure self-balance, so that the floating cutting ring has a self-sealing effect, thereby increasing the conveying pressure of the S-pipe valve. However, when the concrete pump is used for a long time, the cutting ring of the concrete pump is prone to wear.

Concrete pump has now become an indispensable member of engineering construction. In addition to the promotion of urban and rural construction, its own advantages are also very obvious, reducing labor force, shortening construction period, and improving project progress efficiency. The correct use of the concrete pump can not only improve the work efficiency, but also avoid the blockage of the concrete pump. Common concrete pump easily blocked positions and elimination methods are as follows:

Requirements for concrete slump in fine stone concrete pumping
When the concrete with a slump of 10-15 cm is dumped into the hopper, its surface is easily broken; when the slump is less than 10 cm, the concrete is completely broken after tilting, and has a serrated edge, which breaks vertically. into thick blocks;

To improve the pumpability of concrete, it is necessary to increase the amount of cement, use a larger water-cement ratio and sand ratio, and use a stricter aggregate gradation, which means an increase in cost or a decrease in quality. A more economical and effective way is to use admixtures to improve the pumpability of concrete. There are many types of additives, among which the admixtures that can improve the pumpability of concrete include air-entraining agents,

How to maintain and repair the wet spray manipulator? Proper repair and maintenance of the wet sprayer can greatly increase its service life.

The maintenance before and after use of the wet spraying machine requires frequent maintenance, so as to maintain its high performance, as smooth as new, reduce the number of failures, and bring greater benefits to the company. The same goes for wet sprayers. As the most advanced shotcrete support equipment in China, the concrete wet shotcrete machine has a wide range of uses, and the construction environment is also extremely complex,
