Construction method of hand-chiseling texture retaining wall

Abstract

The invention provides a construction method of a hand-chiseling texture retaining wall. The construction method comprises the following steps that (1) a retaining wall body is constructed; (2) a plurality of rib inserting holes are drilled in a retaining wall body template, and tie bars are inserted into the rib inserting holes; (3) reinforcing mesh pieces are hung on a free surface of the retaining wall body, the contact points of the tie bars and the reinforcing mesh pieces are strapped together, and then a tie screw rod is welded on each tie bar; (4) lining strips are machined; (5) wide bottom surfaces of the lining strips are vertically attached to a decoration layer template in a vertical mode; (6) tie screw rod mounting holes are drilled in the other side, where the lining strips ofthe decoration layer template are located, of the lining strips; (7) the decoration layer template is hoisted; (8) the decoration layer template is removed and the lining strips are taken out; and (9) the hand-chiseling texture surface is formed through chiseling, and the tie screw rods extending out a concrete surface are cut off. According to the technical scheme, the retaining wall body and the decoration layer are poured by adopting a step-by-step method, so that the construction quality is good.

Description

technical field [0001] The invention relates to a construction method of a hand-chiseled texture retaining wall, which belongs to the technical field of engineering construction. Background technique [0002] A retaining wall refers to a structure that supports subgrade filling or hillside soil and prevents the deformation and instability of the filling or soil. Since the retaining wall needs to bear large lateral pressure, it has the characteristics of large thickness and large format. 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, and the hand-cut texture retaining wall is the wall of the retaining wall Vertical convex ribs are set, and irregular concave-convex surfaces are chiseled on the outer surface of the convex ribs to form a hand-chiseled texture surface. [0003] Currently, there are two construction methods for making han...

Problems solved by technology

[0004] One is the integral formwork and pouring of the main construction work, which is formed at one time. However, due to the large thickness of the retaining wall, the lateral pressure on the formwork is large when pouring concrete, which is easy to deform the formwork, resulting in poor quality of hand-chiseled textured walls. The aesthetics is poor; and the retaining wall has a large format, and the time for pouring the concrete is too long. When the last concrete poured reaches the preset strength, the strength of the first poured concrete has far exceeded the preset value, and the hardness is too high. Difficult to construct

[0005] The other is that the main construction work first makes the main body of the retaining wall, and then the decoration construction work drills holes on the main body of the retaining wall, drives expansion bolts, and hangs hand-chiseled texture decorative blocks, which are made of prefabricated stone or prefabricated hand-chiseled texture decorative blocks. Hanging, stone or prefabricated hand-chiseled texture decorative blocks are fixed on the outside of the concrete structure by embedded iron parts and steel keels, so that the decorative layer of the retaining wall has insufficient durability and is easy to fall over time, causing serious safety hazards; It is time-consuming and labor-intensive to construct for two different types of work; and the construction is difficult and the construction cost is high
