Description

Technical Field

[0001] This utility model belongs to the field of foundation pit support technology, specifically relating to a support device for single-sided construction of foundation pits. Background Technology

[0002] Drainage pipes are buried at great depths, requiring support for the foundation pit. Currently, sheet piles with internal bracing are commonly used for support. Due to the complex underground pipelines in the renovation project, single-sided support is required for areas such as river channels and slopes. Furthermore, if the surrounding area is close to existing underground facilities such as pipe corridors and pipelines, internal bracing and inclined anchor rods cannot be installed, so cantilever cast-in-place pile support is required, which is costly and time-consuming. Utility Model Content

[0003] The purpose of this utility model is to provide a support device for single-sided construction of foundation pits, which solves the problem that internal supports and inclined anchors cannot be installed when underground facilities such as pipe corridors and pipelines are close by during single-sided construction of foundation pits.

[0004] The technical solution adopted in this utility model is a support device for single-sided construction of a foundation pit, including steel sheet piles. The steel sheet piles are vertically installed on the side of the soil to be constructed. A steel sheet pile waler is provided on the upper part of the side of the steel sheet pile closest to the soil to be constructed. Several channel steels are vertically installed on the side of the steel sheet pile away from the soil to be constructed. The channel steel waler is fixedly connected to the upper part of the several channel steels on the side away from the steel sheet pile. The channel steel waler and the steel sheet pile are connected by steel wire ropes.

[0005] The features of this utility model also include:

[0006] Several channel steels are arranged side by side evenly, and several channel steel limiting holes are opened on each of the channel steels. Channel steel walers are opened with channel steel waler mounting holes. The channel steel walers and channel steels are fixedly connected to each other in the channel steel limiting holes and channel steel waler mounting holes by connecting bolts.

[0007] Several channel steel limiting holes are evenly arranged along the upper edge of the channel steel from top to bottom.

[0008] Several channel steels and sheet piles are topped with protective steel plates, which are located on the upper part of the wire rope.

[0009] The sheet pile waler is horizontally positioned above the sheet pile and is perpendicular to the sheet pile.

[0010] The channel steel waler is horizontally installed on the upper part of several channel steels, and the channel steel waler is perpendicular to the several channel steels.

[0011] The sheet pile waler has several sheet pile waler connection holes, and the channel steel waler has several channel steel waler connection holes. The wire rope passes through the sheet pile waler connection holes and the channel steel waler connection holes.

[0012] The wire ropes are arranged in a crisscross pattern in the connection holes of the sheet pile walers and the channel steel walers, and the wire ropes pass through the connection holes of the channel steel walers and are fixed by wire rope clips.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a support device for single-sided excavation of foundation pits. By setting a top steel wire rope, it effectively controls pit deformation, increases the applicable depth of sheet piles, and saves costs. By setting a protective steel plate, it effectively prevents impurities at the construction site from contaminating existing pipelines, while ensuring normal vehicle traffic on the upper road. It also allows for rapid completion of pit excavation without affecting the normal operation of existing pipelines. Furthermore, by setting channel steel limiting holes, the height can be adjusted on-site, avoiding resource waste caused by cutting channel steel during existing construction methods. It offers greater adaptability for single-sided excavation. The length of the steel wire rope can be adjusted according to the underground facilities such as pipe racks and pipelines on site, adapting to more working conditions. The steel wire rope can also be reused, saving materials and solving the problem of not being able to install internal supports and inclined anchors when underground facilities such as pipe racks and pipelines are close by during single-sided excavation.

The wire rope 4 passes through the connection hole 14 of the channel steel waler and is fixed by the wire rope clip 11, which makes it easy to adjust the length of the wire rope on site through the wire rope clip 11. In other words, it is easy to adjust the width of the portal frame formed by the sheet pile 1, the sheet pile waler 2, several channel steels 5, the channel steel waler 3 and the wire rope 4, thereby improving the utilization rate of the wire rope.
