Underground splicing wall and precast concrete pile for same

Abstract

The invention relates to an underground splicing wall which is formed by splicing a plurality of precast concrete piles sequentially implanted in soil. The underground splicing wall is characterized in that every two adjacent concrete piles are spliced to form a cavity extending in the length direction of the concrete piles, a connecting component is fixed at the middle position of the cavity, the cavity is filled with filler, and the connecting component is embedded in the filler to auxiliarily connect the two adjacent concrete piles together. Since the two adjacent concrete piles are connected through the connecting component and the filler filling the cavity, it is guaranteed that the underground splicing walls are connected and restrained with each other, the underground splicing walls have better integrity, safety of the whole underground splicing wall is greatly improved, and the underground splicing wall is more practical. The invention further relates to the concrete pile.

Description

technical field [0001] The invention belongs to the technical field of underground construction engineering, and specifically relates to an underground splicing wall that can be used as a side wall of a pipe gallery, a side wall of a basement, and a protective wall of a water conservancy project embankment, and also relates to a concrete pile for manufacturing the aforementioned underground splicing wall. Background technique [0002] my country's urban municipal public utilities are constructed and managed by different units. Due to the different construction time, there is no unified planning and comprehensive utilization of urban underground space. Various municipal pipelines are mostly buried directly in the soil layer according to their own systems. Maintenance is inconvenient, easy to damage, and the ability to guarantee supply is often disturbed. Due to the different buried depths of various pipelines, it is easy to cause conflicts. Repeated excavation of the road surf...

Problems solved by technology

This type of underground project has obvious advantages. However, this type of underground splicing wall formed by splicing prefabricated concrete piles, the connection between piles only depends on the fixed connection at the top of the pile body and the binding force of the soil on the lower part of the pile body. The problem that this creates is that the spliced ​​wall is often subjected to continuous, large and uneven lateral pressure, causing local deformation or displacement of the soil used to restrain the lower part of the concrete pile, which in turn causes the lower part of the concrete pile to follow the soil As a result, the splicing wall is partially distorted, cracked, or even broken; in addition, due to different geological conditions and construction defects, the piles will also appear loose and loose in the direction of the horizontal extension of the wall. Cracked open, resulting in gaps or breaks in the wall
