Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] First support the retaining formwork according to the designed retaining wall shape, height and width and fix the retaining formwork on the plane, and then fix multiple grouting pipes between the two retaining formworks. The spacing of the grouting pipes should not be greater than two-thirds of the height of the retaining wall. Since the grouting pressure is not high, in order to save costs, the grouting pipe can use a certain strength PVC pipe. When the thickness of the retaining wall is moderate, multiple grouting pipes can be arranged at equal intervals along the centerline of the two retaining formworks. The grouting pipes are arranged in a plum blossom shape between the two retaining formworks, which can also ensure the uniformity of grouting. Then fill in the block stones in the retaining formwork (the particle size of the block stones is no...

Abstract

The invention discloses a retaining wall construction device. The retaining wall construction device comprises retaining support formworks, grout pouring pipes, a stone material and concrete grout. The retaining wall construction device has the advantage of high construction speed compared with artificial-piling retaining wall construction and has the advantage of concrete saving compared with rubble-concrete retaining wall construction.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a construction device for retaining walls. Background technique [0002] In the construction of expressway subgrade in the mountainous area of ​​western my country, a large number of retaining wall technology should be used. The retaining wall construction technology at the present stage generally has a mortar block (piece) stone retaining wall and a concrete retaining wall. Due to the rich source of stone in the western mountainous area, mortar block (chip) stone concrete is generally used. The mortar block (chip) stone concrete is stacked manually, the construction speed is very slow, the construction efficiency is not high, and the personal safety risk is high during the construction process. However, when concrete retaining walls are used for construction, the amount of concrete used is large and the cost is high. These factors lead to the disadvantages of...
