Sheet-pile wall and construction method thereof

Abstract

The invention belongs to the technical field of civil buildings and concretely relates to a sheet-pile wall which is used for cutting slope protection and provided with a variable cross-section anti-slip pile and a construction method thereof. The technical problems of the prior art that the masonry amount is relatively large, the appearance rating is low, and grass planting afforestation is difficult are solved. The sheet-pile wall comprises a retaining wall, more than one variable cross-section anti-slip pile, more than one first retaining plate and more than one second retaining plate. An anti-slip pile base and more than one anti-slip pile cantilever are sequentially connected in turn from large to small cross-section area. The invention also provides the construction method of the sheet-pile wall, and the method comprises the following steps: A respectively digging pile holes and producing the variable cross-section anti-slip pile; B repeating the step b of the step A for more than one time to obtain more than one variable cross-section anti-slip pile; C respectively producing the retaining plates and the reinforced concrete retaining wall. The sheet-pile wall has features of small masonry amount and strong retaining ability and grass can be planted on the wall.

Description

technical field [0001] The invention belongs to the technical field of municipal buildings, and in particular relates to a pile-slab wall with variable cross-section anti-sliding piles and a construction method thereof for road cutting and slope protection. Background technique [0002] Pile-slab wall is a retaining structure developed from anti-slide piles in my country's railway construction in the 1970s. It is used in railway and highway engineering filling embankment retaining, cutting slope protection and landslide disposal. A retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the deformation and instability of fill or soil. In the cross section of the retaining wall, the part directly in contact with the supported soil is called the back of the wall; the part opposite to the back of the wall is called the wall; the part in direct contact with the foundation is called the base; The top surface of the wall is called the top of ...

AI Technical Summary

Problems solved by technology

The existing upright pile-slab wall is self-excavating side ditch of the subgrade or the edge of the broken platform, and towers above the road in an upright state. The anti-slide piles are usually rectangular with equal cross-section, and the anti-slide piles cantilevered for the convenience of setting soil retaining boards. The section is set as a T-shaped cross-section, but it is a fully enclosed structure composed of retaining boards and piles, which also has the disadvantages of large masonry work, poor aesthetics, and difficulty in planting grass and greening

Moreover, the structure of the vertical pile-slab wall is rigid, and the plant protection cannot be arranged on the wall, and the landscape effect is poor.
