Concrete layer pouring construction method and highway

Abstract

A piled plate-shaped member, a construction method for concrete layer pouring of a road, and a road relate to the technical field of highway engineering. The aforementioned piled plate-shaped member includes a plate-shaped member body as a whole, and a pile head is arranged below the member body. The pile head is connected with the component body above as a whole, and a pile tip is formed at the bottom of the pile head, and the component body is provided with a gripping part that is convenient for people to grasp to lift the pile plate-shaped member and is convenient for people to lift. A stepping portion for stepping on the foot to insert the pile head downward. The sheet-like member with piles can replace the existing steel formwork and be used as a formwork for pouring concrete layers. Using the sheet-like member with piles is easy to install and easy to operate, flexible in construction, can save formwork removal time, shorten the road laying period, and can also Form a smoother road turning arc, which is beneficial to improve the aesthetics of the road.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a construction method for pouring a concrete layer of a highway with a pile-plate-like component and a highway. Background technique [0002] See figure 1 As shown, when laying the concrete layer A of the road, most of the existing methods divide the road surface into two halves with the center line of the road surface as the boundary, lay one half first, and lay the other half after the concrete has solidified to a certain strength. Before pouring concrete, steel form B needs to be installed first, and steel form B needs to be dismantled after the concrete has solidified and reached the design strength. Due to the strong bonding force between the solidified concrete and steel form B interface, the steel form B on the inner side (i.e. The steel form on the side of the other half that has not been poured) still has lapped steel bar C passing through the reinforcement ...

AI Technical Summary

Problems solved by technology

Before pouring concrete, steel form B needs to be installed first, and steel form B needs to be dismantled after the concrete has solidified and reached the design strength. Due to the strong bonding force between the solidified concrete and steel form B interface, the steel form B on the inner side (i.e. The steel form on the side of the other half that has not been poured) still has lapped steel bar C passing through the reinforcement hole. In many cases, it is necessary to use a steel drill to pry the steel form B, and the steel drill to pry off the steel form B It is easy to damage the concrete surface during the process, resulting in defects on the concrete surface, and the road shoulder filling construction must be carried out after the steel form B is removed, and the construction period is difficult to shorten

In addition, the existing steel form B is mostly made of straight steel. In some sharp curve sections, the paved road body does not turn smoothly, and the aesthetics are not high.

[0003] At present, most of the improvement methods for the above problems focus on changing the connection and fixing structure of steel form B to make the assembly operation of steel form B easier (that is, how to quickly install the formwork), but how to make it easier to remove the formwork, how to make the There is still no satisfactory solution for the smoother arc of the corner molding and how to shorten the construction period
