Manufacturing process of decompression and drainage well in basement anti-floating and sealing process

Abstract

The invention relates to a manufacturing process of a decompression and drainage well in a basement anti-floating and a sealing process.The manufacturing process of the decompression and drainage well in the basement anti-floating and a sealing processcomprises the steps that 1, a well with a depth of 50 to 60 cm is dug in the basement; 2,a concrete underlayer is poured at the bottom of the well; 3,a permeable brick is built on the concrete cushion, and the permeable bricks are enclosed as drainage wells; 4,the backwater is filled with coarse sand or slag to form a permeable layer; 5,a drain is opened at intervals along the circumference of the drain well; 6,the water-stop steel ring sleeve is fixed, the lower end of the water-stop steel ring sleeve is inserted into the drainage well, and the upper end of the water-stop steel ring sleeve is exposed outside the bottom plate of the basement; 7,the bottom layer is casted on the bottom plate; 10, the drain hole is formed in the bottom of a 200 to 250CM water stop ferrule. According to the manufacturing process of the decompression and drainage well in the basement anti-floating and the sealing process, the buoyancy of the groundwater to the basement floor can be effectively reduced, which is economical and effective, construction is simple and quick, and the problem of the floating of the basement in the construction stage can be fundamentally solved.

Description

technical field [0001] The invention relates to the construction field, in particular to a manufacturing process and well sealing process of a basement anti-floating decompression drainage well. Background technique [0002] With the development of my country's economy and the acceleration of urbanization, the construction industry has developed rapidly, and there are more and more basements and underground buildings. However, the water level is different in different places, and the buried depth of each building is different. The impact of water on buildings The buoyancy is also different. In addition, the anti-floating design of the basement during the construction stage has not attracted enough attention and corresponding effective solutions. When the basement is below the groundwater level, the buoyancy of the basement will be too large. Therefore, during the construction stage, when the gravity of the basement itself cannot resist the buoyancy of the groundwater to the b...

AI Technical Summary

Problems solved by technology

[0006] 1. The continuous precipitation and drainage of the precipitation well has a certain impact on the water level environment of the basement, which may lead to a drop in the surrounding groundwater level. Secondly, the ground subsidence is accompanied by the loss of sand particles during the pumping process, thus causing damage to existing buildings and municipal roads

[0007] 2. The dewatering well is set about 10 meters below the basement, the construction cost is high, the process is complicated, and the cost of closing the well in the later stage is high

[0008] 3. A water pump is placed in each dewatering well to pump water, the quantity is large and the power consumption is high

[0012] The process is troublesome, affecting the construction work surface, and the actual engineering conditions do not allow it, etc.
