Description

Integral cantilever type barricade that has filter-tank and escape canal

Technical Field

The utility model relates to a geotechnical engineering technical field specifically is an integral type has cantilever type barricade of filter-tank and escape canal.

Background

The retaining wall is used for directly reinforcing a side slope and has been widely applied to projects such as highways, water conservancy projects, railways, house buildings, harbors and the like, and the main structural types are as follows: gravity type retaining walls, buttress type retaining walls, cantilever type retaining walls, anchor rod type retaining walls and the like. The cantilever type retaining wall consists of a bottom plate and a straight wall fixed on the bottom plate, and mainly consists of three reinforced concrete members, namely a vertical wall, a wall toe plate and a wall heel plate; the retaining wall not only needs to provide safe and stable support for the soil body behind the wall, but also needs to be provided with necessary water drain holes, so that overlarge water and soil pressure behind the retaining wall caused by the fact that the soil body behind the wall is rich in water is prevented. The back drain hole of the wall needs not only drainage but also water filtration, so the arrangement of the back reverse filter bag of the wall is particularly important. The reverse filter bag can prevent the loss of filling soil behind the wall and ensure the smoothness of the water outlet. The filtered water can be smoothly discharged into a drainage ditch at the root of the wall. However, the slope soil body on the top of the retaining wall is mixed with sandy soil to flow to the root of the wall along the retaining wall under the scouring of rainwater, and after the slope soil body is accumulated for a long time, a drainage system is easy to block, and the dredging is time-consuming and labor-consuming.

In addition, the construction of the common drainage ditch is carried out after the construction of the retaining wall is finished, and even the construction is carried out again after soil body backfilling. According to on-site feedback, because the depth of a drainage ditch is not considered during the design of the retaining wall, the embedding depth of the wall toe is too shallow, the drainage ditch cannot be constructed due to insufficient excavation depth, or the retaining wall is kept away from the wall toe for avoiding the wall toe, so that space waste is caused, and the drainage effect is influenced.

For example, the invention is disclosed in patent application publication No. CN114108691A entitled construction process of novel counterfort retaining wall, wherein a construction operation method for excavating drainage ditches after the retaining wall is erected and a concrete hardened surface is poured is disclosed, which can not avoid various problems in the construction process, the drainage ditches can only be arranged at the outer side of a toe board where concrete is poured, the distance is far, the drainage effect is affected, and the flat net arranged on the drainage ditch can not solve the problem that the drainage ditches are silted up due to sandy soil washed by rainwater on the slope. Therefore, there is a need for a cantilever retaining wall with integrated filter tanks and drains to solve these problems.
