1. Control workability and slump of concrete

The pumped concrete shall be designed in strict accordance with the regulations, the slump shall be strictly controlled, and the following principles shall be followed. (1) The ratio of the maximum particle size of coarse aggregate to the diameter of the conveying pipe should be: when the pumping height is below 50 m, it is not suitable for gravel

As the terminal equipment for pumping concrete, the mobile hydraulic concrete placing boom is used to send the pumped concrete through the pipeline to the formwork of the component to be poured. The hydraulic concrete placing boom does not need to be fixed when used, and the position and conveying direction can be flexibly changed according to the needs of the construction site.

HGY24 concrete hydraulic concrete placing boom is a terminal equipment used in conjunction with concrete pumps. It is suitable for the construction of high-rise buildings and large-area concrete pouring projects. Reduce construction cost, improve concrete pouring quality and construction progress.

For the safety of construction personnel, the safety operation process of wet concrete spraying manipulator is specially made:

1. It is strictly forbidden to use the manipulator as a crane or lifting platform.

The fine stone concrete pump is a special concrete pump, which is welcomed by the majority of construction parties because it is widely used in floor heating projects and floor construction. So at the construction site, what are the pumping requirements for the fine stone concrete pump? Now let's take a closer look.

At present, the concrete wet concrete spraying truck shotcrete truck, as a kind of concrete machinery and equipment favored by the majority of construction parties, has greatly improved the efficiency of construction.

The operator of the delivery pump should concentrate on the pumping construction and pay attention to the reading of the pumping pressure gauge at all times. Once the reading of the pressure gauge suddenly increases, the pump should be reversed for 2 to 3 strokes immediately, and then the pump should be corrected. The blocked pipe can be eliminated . If the blocked pipe has not been eliminated after reverse pumping (forward pumping for several operating cycles),

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. With the rapid development of underground spaces such as highway and railway tunnels, urban subway tunnels, and mining resources, the demand for concrete shotcrete is increasing

In the construction of concrete pumping, the cleaning of concrete is an essential and important step after pumping. A good cleaning method can not only clean the pipeline, but also transport all the concrete in the pipeline to the pouring site, not only does not waste concrete, And economical and environmentally friendly. There are three main types of water washing methods commonly used in S-tube valve concrete pumps, which are described as follows

The service life of concrete pumps has always been a concern of the majority of construction parties. If you want to extend the service life of concrete pumps, you must pay attention to the maintenance of concrete pumps. Many customers only know to pay attention to daily maintenance, but how to maintain and check?

Concrete wet concrete spraying shotcrete truck is a special shotcrete support equipment that sprays ready-mixed concrete to the sprayed surface at high speed, and forms a concrete support layer through rapid setting.

The concrete placing boom is a concrete equipment for conveying and distributing, which is connected with the outlet of the concrete drag pump.

As an auxiliary equipment of the concrete pump, it is connected by a standard conveying pipe, just like a manipulator, which can quickly and accurately deliver the concrete to any pouring part of the working surface for continuous pouring, expand the concrete pumping range, and effectively

Mobile Concrete Placing Boom Features:

1. There is a dragging structure, which can be quickly and easily moved to the required position in the construction site;

2. The short-distance construction site can be pulled by the tractor to transfer the equipment, and the equipment transfer can be completed in a short time;

3. It can be applied to construction sites restricted by tower cranes or lifting equipment, and is very efficient;

The concrete placing boom adopts a 360-degree full-rotation boom-type placing structure. The whole machine is easy to operate, flexible to rotate, and has the characteristics of high efficiency, energy saving, economy and practicality. Concrete placing machine is to expand the scope of concrete pouring.
