Support structure and construction method of recyclable prefabricated collection and drainage extruded and expanded tire piles

Abstract

The invention relates to a support structure and construction method of a recyclable and assembled drain pile extruded and expanded tire pile, which belongs to the technical field of building foundation engineering. The top of the inner pile penetrates from one end of the cylindrical expansion structure until it is exposed from the other end of the cylindrical expansion structure. The spring at the end of the cylindrical expansion structure is connected with the sleeve at the end of the inner pile to form a whole. The bottom of the cylindrical expanded structure pile is cemented. The pumping device is composed of a pump and a pump. The pump is connected to the pump. The pump extends into the inner pile pipe to the bottom of the water collection bag to form a recyclable assembly drainage squeeze expansion tire. Pile, the connecting plate between the piles is a steel plate with a cross-section of a few characters, and the connecting plate between the piles connects the extruded and expanded plates of the adjacent pile bodies through bolts to form a recyclable assembly drainage extruded and expanded carcass pile support structure. The invention integrates the draining function and the support function, can speed up the construction of the foundation pit engineering, and the pile body can be completely recovered after the foundation pit engineering is completed.

Description

technical field [0001] The invention relates to the supporting structure technology of recyclable and assembled water collection and drainage extruded and expanded tire piles, belonging to the technical field of building foundation engineering. Background technique [0002] The foundation pit support structure can retain soil and cut off water, and has the functions of ensuring the construction space of underground structures, controlling soil deformation, and ensuring that the construction work surface is above the groundwater level. As a commonly used support method for deep foundation pits, support piles have the characteristics of good support performance and simple construction. At present, support piles often use reinforced concrete round piles combined with cement mixing piles to form an enclosure wall or vibrating immersed tubes. T-shaped piles may use the SMW construction method, the reinforced concrete round piles are expensive, the construction speed is slow, and ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned structure is only part of the recovery pile material, most of the material is still wasted and unusable, the oil between the templates is easy to cause environmental pollution, and this structure cannot realize the integration of support and drainage. In summary, a new method is proposed The recyclable prefabricated water collection and drainage extruded tire pile that combines the drainage function and support function into one. The pile structure can speed up the construction of the foundation pit project, and the pile body can be completely recycled after the foundation pit project is completed, saving a lot of resources , has important social and economic value
