Example Embodiment

[0016] refer to figure 1 As shown, the air pressure splitting foundation reinforcement treatment structure provided by the first embodiment of the present invention includes a vacuum preloading and sealing treatment system for the soil body in the construction area and a high-pressure gas injection system, and the high-pressure gas injection system includes The high-pressure gas injection pipe 1 and the high-pressure gas injection device 2 are provided, and an exhaust and drainage plate 3 is punched in the soil body of the construction area. The exhaust and drainage plate 3 has a discharge end connected to the outside world, and the discharge end is configured with Valve 4. After the high-pressure gas is injected, it is generally only necessary to open the valve 4 to discharge the water and gas together. However, in order to improve the suction and discharge effect, a suction and discharge device 5 can also be connected to the discharge end. There is a water-stop curtain 6, an...

Abstract

The invention discloses an air pressure split foundation strengthening treatment structure. The air pressure split foundation strengthening treatment structure comprises a vacuum preloading sealing treatment system and a high-pressure air injection system of a construction area soil body. The high-pressure air injection system comprises a high-pressure air injection pipe and a high-pressure air injection device which are arranged in the construction area soil body in a beating manner. An air and water discharging plate is arranged in the construction area soil body in a beating manner and provided with a discharging end connected with the outside. The discharging end is provided with a valve. A waterproof curtain is arranged around the construction area soil body in a beating manner. Bentonite is added in cemented soil used for the waterproof curtain. The invention further provides a method adopting the above air pressure split foundation strengthening treatment structure for foundation strengthening treatment. According to the provided above structure and method, the discharging efficiency of water in the soil body can be improved, meanwhile, the erosion of underground water on the cemented soil forming the waterproof curtain can be reduced after the bentonite is added in the waterproof curtain, and the soil body strengthening effect is enhanced.

Description

technical field [0001] The invention relates to a pneumatic splitting foundation reinforcement treatment structure. The present invention also provides a method for foundation reinforcement treatment using the above-mentioned pneumatic splitting foundation reinforcement treatment structure. Background technique [0002] In soft soil areas rich in water, the water in the soil is often not fully removed in traditional soil reinforcement, resulting in problems such as settlement due to the re-discharge of water after reinforcement treatment. In order to solve this problem, engineers used the method of air pressure splitting to form groundwater drainage channels in the soil to facilitate more thorough drainage. However, the traditional method of pneumatic splitting to strengthen the soil has poor pumping efficiency. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is to provi...
