Embodiment Construction

[0015] The construction method for controlling the flatness of the reinforced soil retaining wall wall adopts the following steps: a. Prefabricate the reinforced soil retaining wall panel 2 with the reserved vertical through hole 1; b. Accurately release the masonry sideline on the concrete foundation 3, Lay the bottom reinforced earth retaining wall panel 2 on the concrete foundation 3; c, pave the filler 4 to the designed height of the reinforcement material 5 outside a certain distance outside the reinforced earth retaining wall panel 2, fill and roll compactly, and then lay the reinforcement material 5. The front end of the reinforcement material 5 is firmly connected with the reinforced earth retaining wall panel 2, and the rear end of the reinforcement material 5 is temporarily fixed with tensioning equipment, and the tightness of each reinforcement material is kept consistent, and then spread out at a certain distance above the reinforcement material 5 Lay filler 4, leve...

Abstract

The invention particularly discloses a construction method for controlling flatness of a wall surface of a reinforced retaining wall and solves the problem that the flatness of wall surfaces of existing reinforced retaining walls is difficult to control. The construction method comprises the steps of a, prefabricating reinforced retaining wall panels with vertical through holes reserved; b, building the bottom-layer reinforced retaining wall panel on a concrete foundation through mortar; c, spreading padding materials at a certain distance from outer sides of the reinforced retaining wall panels, then laying rib materials, spreading the padding materials at a certain distance above the rib materials, and performing leveling and rolling compaction; performing filling within a certain distance from the outer sides of the reinforced retaining wall panels; d, when installing the upper-layer reinforced retaining wall panels, inserting dowels into the vertical through holes, and tightening puller bolts; performing operation as per Step c until filling is finished, taking out the dowels, loosening the puller bolts, and removing restrained beams; e, repeating Step d until construction of the last-layer reinforced retaining wall panel is finished. According to the construction method, the flatness of the wall surface of the reinforced retaining wall is controlled effectively through reasonable process steps.

Description

technical field [0001] The invention relates to a construction method for a reinforced earth retaining wall, in particular to a construction method for controlling the flatness of the reinforced earth retaining wall. Background technique [0002] Reinforced soil is to add a certain amount of materials (reinforcement) with tensile properties to the fill, which has been widely used in fill projects in the last century. Reinforced soil retaining wall is a light-duty retaining form that combines reinforced soil technology and retaining structure organically. It has light structure, reasonable force, low foundation treatment requirements, good structural flexibility, and can better adapt to foundation deformation and earthquakes. , low construction cost, saving land and other characteristics, it is highly favored by the engineering community, and is used as one of the light retaining structures for roads, railways, water conservancy, mines and other filling sites. [0003] The r...
