High-rise pouring concrete method High-rise concrete pouring technology link analysis

1, high-rise building concrete pouring is mainly with the help of ground pump transmission capacity, vertical distance transmission of concrete. First of all, in the process of supporting the template of the floor, the hole of the pump pipe is reserved to ensure that the pump pipe can pass through the floor slab along the hole and arrive at the concrete work surface.

2, grouping the pump pipe: according to the site conditions, calculate the length of the pump pipe, according to the pre-set holes, the assembly of the pump pipe. The length of the pump pipe is generally 3 meters, 2 meters, 1 meter, etc., as well as 90-degree and 45-degree elbow pipe. Assemble as needed. During the assembly process, avoid too many elbows, resulting in the blocking of the pipe during the concrete pouring process.

3, connecting the flat plate with the fabric machine: the role of the flat plate fabric machine is to pour the concrete through the conduit to the construction surface, through the multi-angle rotation of the fabric machine, to meet the requirements of the construction surface, to ensure that all parts of the concrete pouring.

4, rent and install the ground pump: the floor riser and horizontal pipe assembly is completed, before the concrete is poured, the ground pump truck will be driven to the construction site, into the ground pump truck conduit assembly. The premise is that the height of the horizontal pipe should be determined according to the height of the conduit of the floor pump truck, to ensure that the conduit of the floor pump truck and the horizontal pump pipe can be closely connected.

5, after the assembly is completed, with the tower crane will be the floor of the bending pipe of the fabric machine lifting, manual control of the bending pipe rope, the fabric mouth aligned with the parts of the pouring of concrete. The concrete mixer truck will unload the concrete into the hopper of the floor pump truck, and through the high pressure of the floor pump truck, the concrete will be transferred to the construction work surface.
