Gravity type point-adhered rubble stone plant caulking ecological retaining wall and construction method thereof

Abstract

The invention discloses a gravity type point-adhered rubble stone plant caulking ecological retaining wall and a construction method thereof. The retaining wall comprises compaction pure soil, a concrete cushion and a rubble stone base layer, wherein a trapezoidal wall body is arranged above the rubble stone base layer; the wall body is composed of multiple rubble stone layers and a concrete coping at the upper part; each rubble stone layer is formed by laying multiple blocks of rubble stone through cement mortar; a space between cracks of outer walls of the rubble stone layers on an air face is filled with point-adhered rubble stone or residual soil slurry; cement mortar bricking is carried out between the point-adhered rubble stone and rubble stone; vegetation is uniformly transplanted on the outer wall of cracks of residual soil slurry at intervals; a drainage ditch is formed in the upper end face of the rubble stone base layer; a drainage ditch retaining wall is arranged on the outer side of the drainage ditch. The gravity type point-adhered rubble stone plant caulking ecological retaining wall disclosed by the invention has the advantages as follows: (1), cement dosage is less; (2), the engineering cost is low; (3), plants grow quickly, are attractive and durable, and can absorb heat greatly, reduce the heat island effect, adsorb dust, retain soil and allow water to permeate through; (4), the whole permeability coefficient is high, plenty of moisture can permeate through the wall body while plant roots retain soil; (5), drainage holes are not required to be reserved; (6), the stability is good.

Description

technical field [0001] The invention relates to the field of an ecological wall and its construction technology, in particular to a gravity-type point-glued rubble plant caulking ecological retaining wall and a construction method thereof. Background technique [0002] The traditional gravity-type rubble retaining wall can be divided into two types: cement mortar masonry and dry-build, or called "gravity cement mortar masonry rubble retaining wall" and "gravity dry-build rubble retaining wall". ". The surface of the rubble retaining wall built with gravity cement mortar is divided into two types: cement mortar pointing and joint free, or "gravity cement mortar masonry, pointing rubble retaining wall, gravity dry masonry rough Stone free pointing retaining wall". [0003] Disadvantages of gravity cement mortar masonry and pointing rubble retaining wall: ①Using a large amount of cement; ②Cement mortar pointing is not beautiful, durable, and does not absorb sunlight and he...

AI Technical Summary

Problems solved by technology

[0003] Disadvantages of gravity cement mortar masonry and pointing rubble retaining wall: ①Using a large amount of cement; ②Cement mortar pointing is not beautiful, durable, and does not absorb sunlight and heat; ③The adjacent part of the retained drain retains soil The soil in the wall is also gradually lost. Once the drain is blocked, the excessive soil pressure will cause collapse, which poses a safety hazard; ④ the cost is high

[0004] The disadvantages of gravity dry-laying rubble retaining wall are: ① The overall stability is poor, and the gaps in the wall are large; ② Due to the irregular rubble, it is necessary to use smaller stone flakes for lining, which makes it difficult for workers to operate and low work efficiency; ③ The soil is easy to Loss through the gaps in the wall; ④ The surface is not beautiful, does not absorb sunlight and heat

[0005] There are problems with the exposed stones of the above two kinds of retaining walls: first, they are extremely inconsistent with the surrounding trees and vegetation, giving people a visual impression that is not beautiful; second, the surface cannot absorb the heat of the sun, which accelerates the urban heat island effect ; The third is that the air quality cannot be improved; the fourth is that the stability is poor and there are potential safety hazards; the fifth is that the cost is relatively high
