Concrete road shoulder slip form

Abstract

A concrete road shoulder slip form belongs to the technical field of roadbed concrete construction, and a rotatable roll shaft is mounted between a contour line of a discharge gap of a hopper and a shaping template corresponding to the contour line, when the slip form is used for paving a concrete road shoulder, the rotatable roll shaft extrudes the concrete to move towards the direction of a plane template by friction force generated by sliding and rolling the concrete in the hopper, so that the extrusion forming speed of the concrete road shoulder is increased; meanwhile, the rotatable roller shaft can rub out cement slurry from concrete, the cement slurry is accumulated and sealed on the surface of the concrete road shoulder and between the surface of the concrete road shoulder and the plane formwork, and after plastering of the plane formwork, the honeycomb pitted surface of the concrete road shoulder is eliminated.

Description

technical field [0001] The invention belongs to the technical field of road concrete construction, in particular to a concrete road shoulder sliding form. Background technique [0002] In order to ensure the robustness of the road, it is necessary to pave concrete shoulders on both sides of the road. The concrete shoulders of urban roads and high-grade highways have always used concrete prefabricated modules. After the modules reach a certain strength, they are transported to the site for manual paving. The problems of this method are: (1) It needs to consume a large amount of wood or boards as formwork; (2) It needs to set up a certain prefabricated site, and there are a series of complicated site work before construction. After the prefabricated modules reach a certain strength (3) Necessary tooling and transportation of prefabricated modules are required. During the transportation of prefabricated modules, it is easy to cause damage and serious waste during transportation...

Problems solved by technology

The problems of this method are: (1) It needs to consume a large amount of wood or boards as formwork; (2) It needs to set up a certain prefabricated site, and there are a series of complicated site work before construction, after the prefabricated modules reach a certain strength (3) Necessary tooling and transportation of prefabricated modules are required. During the transportation of prefabricated modules, it is easy to cause damage and serious waste during transportation; (4) The labor intensity is high and the construction speed is high. Slow, because it is artificial paving, the quality is difficult to guarantee

[0005] The above-mentioned prior art has the following defects: one is that the surface smoothness and flatness of the concrete shoulder paved by the slipform are poor; The smoothness and flatness of the road increase the construction machinery; the third is that when paving the concrete road shoulder, two different materials need to be provided: concrete and cement slurry, which increases the production process and links; the fourth is to improve the quality of the concrete road shoulder. Smoothness and flatness need to be completed by two sets of devices, the sliding form and the troweling device, and the coordination between the two is also required.
