Embodiment Construction

[0013] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0014] First support the retaining formwork 1 according to the designed retaining wall shape, height and width and fix the retaining formwork 1 on the plane, then fix a plurality of grouting pipes 3 between the two retaining formworks 1, the grouting pipes 3. The layout spacing should not be greater than 2 / 3 of the height of the retaining wall. Because the grouting pressure is not large, in order to save costs, the grouting pipe 3 can adopt a certain strength PVC pipe. When the thickness of the retaining wall is moderate, a plurality of grouting pipes 3 can be arranged at equal intervals along the centerlines of the two retaining formworks 1; A plurality of grouting pipes 3 are arranged in a plum blossom shape between the two retaining formworks 1, so as to ensure the uniformity of grouting. Then fill the stone material 2 into the retaining template 1 (t...

Abstract

The invention discloses construction equipment for retaining walls, which comprises two supporting and retaining formworks and a plurality of grouting pipes; the two supporting and retaining formworks are fixed at both sides of a retaining wall along the extension direction of the retaining wall to be constructed; the grouting pipes are fixed between the two supporting and retaining formworks along the extension direction of the retaining wall; the grouting pipes are hollow pipes, and the wall of each grouting pipe is provided with a plurality of grout outlets. The construction equipment for retaining walls provided by the invention has the advantage of high construction speed in comparison with artificial pilling type retaining wall construction, and has the advantage of concrete saving in comparison 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...
