Embodiment Construction

[0030] Such as Figure 1~3 as shown,

[0031] The construction method of the integral type prestressed reinforced retaining wall of the present invention comprises the following technical steps:

[0032] 1. Select a reasonable axis of the retaining wall to excavate the foundation groove of the retaining wall. One side of the foundation groove of the retaining wall is a slope, and the width of the excavated foundation groove can be determined according to the design width of the foundation of the retaining wall.

[0033] 2. Concrete bottom slab 1 of pouring retaining wall requires the design of the concrete bottom slab to meet the requirements of foundation bearing capacity.

[0034] 3. Install steel bars 5 perpendicular to the bottom plate on the bottom plate 1, and the length of the steel bars 5 exceeds the design elevation of the retaining wall.

[0035] 4. Lay a layer of geogrid or geotextile 3 on the upper surface of the solid part of the foundation groove. In the next ...

Abstract

The invention discloses an integral prestress reinforced earth retaining wall construction method. The method comprises the steps of excavating an earth retaining wall foundation trench, pouring a concrete floor of an earth retaining wall, arranging vertical rebars, laying geogrids and geotechnical cloth, refilling a backfill material by certain thickness, overturning the geogrids and geotechnical cloth to wrap the backfill material inside, refilling the backfill material multiple times to the designed height of the earth retaining wall, pouring a top plate, tensioning and locking the rebars, and driving a pre-stressed anchor cable to a side slope from the edge of a concrete cover plate. According to the method, by arranging ribs in the horizontal direction and applying prestress in the vertical direction, cost is lower compared with a reinforced concrete retaining wall; the mechanical property of reinforcement materials is fully utilized, the integral type earth retaining wall is formed, and pouring of a concrete panel is not needed. The method has the advantages that construction is easy, economic effectiveness is high, and implementation effect is good.

Description

technical field [0001] The invention belongs to the technical field of slope engineering, and particularly designs a construction method of an integral prestressed reinforced retaining wall. Background technique [0002] Hills and mountains are widely distributed in the central and western regions of my country. With the acceleration of road and bridge construction in the western region, it is necessary to build retaining walls to deal with a large number of engineering slopes. The retaining wall has the advantages of stabilizing the slope, simple structure, and the top platform can be used, and has been widely used in mountain road construction. For a long time, due to the impact of geological disasters and climate environment, landslides and road collapse accidents have occurred frequently in western my country, which not only easily caused casualties, but also accompanied by a large amount of economic losses. Therefore, the safety issues of various slope engineering must...
