Permeable double-row retaining wall for urban buildings

Abstract

The invention discloses a permeable double-row retaining wall for urban buildings, and belongs to the technical field of foundation maintenance of the urban buildings. A water delivering pipe is pre-buried in a concrete base, and upper-layer concrete wall bodies of the retaining wall are connected with the concrete base arranged below the ground; the first row of concrete wall body and the secondrow of concrete wall body are connected through a reinforcing rib plate to form a hollow trapezoid body, and groove interior permeable holes are formed in the bottom of the hollow trapezoid body; a plurality of rows of permeable holes are formed in the second row of concrete wall body and penetrate through the concrete wall body; and a gravel backfill layer is laid on the hollow trapezoid body. The retaining wall is good in structural stress performance, easy to implement, good in stability, small in size and low in self-weight, and has good drainage capacity, and meanwhile through combinationof the double-row concrete wall bodies and the reinforcing plate, the anti-sliding and anti-toppling capability of the retaining wall is enhanced.

Description

technical field [0001] The invention belongs to the technical field of urban building foundation maintenance, in particular to a permeable double-row retaining wall for urban buildings. Background technique [0002] Slope engineering is in a particularly important position in the whole large civil engineering because of the large amount of slope engineering, high technical difficulty and high accident rate. The object of slope engineering is rock or soil. Rock and soil are naturally generated and cannot be artificially manufactured. The characteristics are: properties vary from place to place and from time to time; human understanding cannot be exhaustive; mechanical parameters cannot be provided accurately; design level It varies from person to person. The existence of these characteristics has brought great difficulties to the construction of the project. The result is: improper grasp of rock and soil mass, high accident rate (it is understood that in construction project...

Problems solved by technology

The object of slope engineering is rock or soil. Rock and soil are naturally generated and cannot be artificially manufactured. The characteristics are: properties vary from place to place and from time to time; human understanding cannot be exhaustive; mechanical parameters cannot be provided accurately; design level vary from person to person

The existence of these characteristics has brought great difficulties to the engineering construction. The result is: improper grasp of rock and soil mass, high accident rate (it is understood that in construction projects, the slope accident rate accounts for about 70%); different design schemes, cost differences Large; geological conditions vary greatly, and in many cases there is a lack of economical and reasonable slope support methods

[0003] There are many retaining structures in today's cities, the most important one is the retaining wall, which is mostly a concrete component with a cold and hard appearance. After the water is discharged from the drain hole on the concrete wall, it is easy to efflorescence along the wall, which affects the durability of the structure and Affects the appearance; the scattered flow of the concrete drain hole is easy to cause erosion of the back soil in front of the retaining wall, which will cause partial loss of backfill soil in front of the wall over time, softening of the foundation at the toe of the wall, lower bearing capacity, prone to landslides, and affect the city building stability
