Problems solved by technology

At present, the traditional construction methods of common retaining walls are stacking of rock and soil and concrete pouring on site. Not only the material consumption is large, the construction is complicated, but the cost of labor and materials is high; the quality is not easy to control, the construction period is long, and it is not easy to apply in time constraints. emergency engineering

Embodiment 1

[0032] A hollow triangular arc-shaped retaining wall mainly includes n hollow triangular arc-shaped retaining wall main bodies 1 , m support piles 2 and rigid connectors 3 . n>1. m>1. n and m are integers. m=2n.

[0033] The main body 1 of the hollow triangular arc-shaped retaining wall is located on one side of the slope 5 .

[0034] Further, there is filled soil 4 between the hollow triangular arc-shaped retaining wall main body 1 and the side slope 5 . The filling 4 is construction waste.

[0035] The main body 1 of the hollow triangular arc-shaped retaining wall mainly includes a hollow retaining wall block I11 , a hollow retaining wall block II12 , a hollow retaining wall block III13 and a support column 14 .

[0036] The hollow retaining wall block I11 is a hollow cuboid.

[0037] The hollow retaining wall block II12 is a hollow arc-shaped three-dimensional structure. There are several drainage holes 121 on the block II12 of the hollow retaining wall. The drainag...

Embodiment 2

[0052] A construction method for a hollow triangular arc-shaped retaining wall, comprising the following steps:

[0053] 1) Retaining wall design;

[0054] Determine the type of hollow triangular arc-shaped retaining wall main body 1 and support pile 2 according to the geological conditions and slope soil conditions, mainly including the cross-sectional form of the hollow triangular arc-shaped retaining wall main body 1 and support pile 2, prefabricated materials, reinforcement conditions and Support pile 2 buried depth.

[0055] 2) Determine the foundation and drive into the supporting piles; the main steps are as follows:

[0056] 2.1) Pile positioning;

[0057] 2.2) Inserting the prefabricated pile into the joint grouting method through static pressure or drilling (that is, drilling through a drilling rig, then inserting the prefabricated pile into the drilled hole, and then pouring concrete around the drilled hole so that the pile and soil are in close contact) to drive ...

Abstract

The invention discloses a hollow triangular arc retaining wall. The retaining wall mainly comprises multiple hollow triangular arc retaining wall bodies, multiple bearing piles and rigid connecting parts; the hollow triangular arc retaining wall bodies are located on one side of a slope, one hollow triangular arc retaining wall body is supported by two adjacent bearing piles, each hollow triangular arc retaining wall body mainly comprises a hollow retaining wall division block I, a hollow retaining wall division block II, a hollow retaining wall division block III and a supporting column, andthrough the rigid connecting parts, anchorage parts of the hollow retaining wall division blocks III and anchorage parts of the bearing piles are anchored. The hollow triangular arc retaining wall isused for bearing pressure, the use amount of concrete and reinforcing steel bars is greatly reduced, the triangular structure saves cost as much as possible, and stable and safe supporting of the mountain slope body is ensured.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a hollow triangular arc-shaped retaining wall. Background technique [0002] The retaining wall is a building that supports the roadbed fill or hillside soil, prevents the fill or soil from being deformed and unstable, and bears lateral pressure. [0003] Retaining walls are widely used in roadbed filling, hillside rock and soil support and landslides and emergency rescue work of geological disasters. The retaining wall is usually provided with a concrete wall with a steel skeleton, and drainage pipes are distributed on the concrete wall. At present, the traditional construction methods of common retaining walls are stacking of rock and soil and concrete pouring on site. Not only the material consumption is large, the construction is complicated, but the cost of labor and materials is high; the quality is not easy to control, the construction period is long, and it is ...
