Earthwork transportation system used for foundation pit engineering and construction method

Abstract

The invention discloses an earthwork transportation system used for foundation pit engineering and a construction method. The transportation system comprises a steel protective barrel, a power device,a grout separating device, a guide pipe, a gas conveying pipe, a pipe-blocking-preventing device, a gas-liquid mixing device and a fixed supporting structure; the steel protective barrel is embeddedinto soil and is filled with mud and earthwork mixing liquid, the power device is an air compressor, the grout separating device is used for guaranteeing the using performance and circulated utilization of mud, the guide pipe is divided into a vertical part and a horizontal part, the vertical part of the guide pipe is inserted into the steel protective barrel, and the horizontal part of the guidepipe is paved on the ground and fixed; the starting end of the gas conveying pipe is connected with the power device, the vertical part of the guide pipe is inserted into the steel protective barrel in a fixed connection manner, and the tail end is connected with the gas-liquid mixing device; and the pipe-blocking-preventing device prevents the transporting pipe from being blocked. The influencesof surrounding environments on the construction process using the transportation system are small, the occupied construction floor space is small, the earthwork transportation system is suitable for city compact district foundation trench earthwork construction, and pollution to the surrounding environment can be reduced.

Description

technical field [0001] The invention belongs to the technical field of foundation pit construction, and in particular relates to an earthwork transportation system and a construction method for foundation pit engineering. Background technique [0002] With the development of urban construction, high-rise buildings and large public buildings are gradually increasing. However, the excavation of foundation pits in densely built urban areas is restricted by negative factors such as small sites and polluted environment, which brings huge costs and time limit for engineering construction. challenge. Especially for construction projects in urban core areas, such as (semi) cover-excavation construction, due to the limited space, the space for earthwork lifting and transfer is extremely small, and it is difficult for large-scale earthwork equipment to operate, which seriously hinders the construction progress; at the same time, conventional earthwork The huge dust and smog caused by...

[0002] With the development of urban construction, high-rise buildings and large public buildings are gradually increasing. However, the excavation of foundation pits in densely built urban areas is restricted by negative factors such as small sites and polluted environment, which brings huge costs and time limit for engineering construction. challenge

Especially for construction projects in urban core areas, such as (semi) cover-excavation construction, due to the limited space, the space for earthwork lifting and transfer is extremely small, and it is difficult for large-scale earthwork equipment to operate, which seriously hinders the construction progress; at the same time, conventional earthwork The huge dust and smog caused by the excavation mode in urban areas also bring new problems to urban environmental protection
