Assembly-type protective construction method for slab-pile wall through pre-stressed anchor cables

Abstract

The invention relates to an assembly-type protective construction method for a slab-pile wall through pre-stressed anchor cables. The slab-pile wall mainly comprises a prefabricated pipe pile, a prefabricated slab-pile wall body, the in-wall pre-stressed anchor cable, a post-pouring foundation and the fill side pre-stressed anchor cable. The assembly-type protective construction method comprises the steps that 1, the prefabricated pipe pile is internally provided with an upper end plate and a lower end plate, core grouting is conducted between the lower end plate and the top of the pipe pile through concrete, the pre-stressed anchor cables are arranged on the top of the upper end plate, and the tops of the anchor cables and reserved reinforcing steel bars on a pile wall are together anchored to the top of a prefabricated slab-pile wall body foundation; 2, the prefabricated slab-pile wall body is internally provided with the vertical pre-stressed anchor cables and a drainage channel, the bottom of the slab-pile wall body foundation is embedded in the top of the prefabricated pipe pile, and the post-pouring foundation is arranged around the slab-pile wall body foundation; and 3, the slab-pile wall body and a side slope are pulled and connected through the pre-stressed anchor cables, and gas bubble light soil is backfilled between the slab-pile wall body and the side slope. According to the assembly-type protective construction method for the slab-pile wall through the pre-stressed anchor cables, integral assembly-type installing of the protective structure of the slab-pile wall is achieved, and meanwhile the stability of the slab-pile wall is effectively ensured by arranging the structures of the pre-stressed anchor cables and the like.

Description

technical field [0001] The invention relates to a prestressed anchor cable assembled pile plate wall protection structure and a construction method. The invention belongs to the field of foundation and foundation engineering, and is suitable for the construction of anti-sliding retaining walls of embankments and also for the reinforcement engineering of landslide bodies. Background technique [0002] The retaining wall is an important retaining structure, which is widely used in slope reinforcement projects. During the application process, in order to adapt to the construction conditions in different regions (such as foundation, material source, terrain, etc.) and different use requirements (such as building height, stability, etc.), various forms of retaining walls have been developed, such as cantilever type, buttress type, reinforced soil type, anchor type, soil nail type and unloading plate type, etc. The process is simple, The technology is mature, but the structure is...

Problems solved by technology

Vertical prestressed anchor retaining wall is a new type of retaining structure formed by the combination of gravity retaining wall and vertical prestressed anchor. On the basis of this, another new type of retaining structure is formed using the bolt technology. Compared with the traditional retaining wall, these two types of new retaining walls have a better retaining effect, and the construction technology is relatively traditional. There is no technical It is a difficult process, but its main structure is still a gravity retaining wall with cast-in-place reinforced concrete structure. It is difficult to avoid basic processes such as formwork support, formwork removal, and maintenance. The setting operation of the slurry anchor rod is also relatively cumbersome
