Concrete pouring device for highway construction

Abstract

The invention discloses a concrete pouring device for highway construction, and relates to the technical field of highway construction. The device further comprises a knocking mechanism. Knocking mechanisms are respectively mounted on the bottom plate and the top plate; the knocking mechanism comprises a guide bracket, a crankshaft, a connecting rod, a push rod, a knocking head and a belt pulley; the lower end of each push rod is fixedly connected with a pressure spring; mounting blocks are fixedly connected to the lower ends of the pressure springs; a knocking head is mounted at the lower part of each mounting block; when any one or more knocking heads of the knocking mechanism on the top plate are in contact with the upper end of the template, the knocking heads of the knocking mechanism on the bottom plate are in contact with the rear end face of the template, wherein the positions of the knocking heads are corresponding and the number of the knocking heads is the same. The device has the beneficial effects that bubble discharge in concrete near the formwork can be effectively improved, and the concrete pouring quality is improved.

Description

technical field [0001] The invention relates to the technical field of road construction. Background technique [0002] In highway construction projects, concrete pouring is often used to harden and level the road surface. In the process of concrete pouring, it is generally necessary to use formwork to support the formwork stably on both sides of the road to form the boundary of the road. After filling the pouring water After concreting, it is necessary to use tools such as vibrating rods to remove air bubbles in the concrete to make the road surface smoother. However, due to the relatively large volume of tools such as vibrating rods, the operation is relatively rough when used manually. The impact of concrete vibration is relatively small, and the end face of the formwork in contact with the concrete is prone to form cavities at the boundary of the concrete due to factors such as irregularities, which may cause air bubbles in the concrete near the formwork, affecting the f...

The impact of concrete vibration is relatively small, and the end face of the formwork in contact with the concrete is prone to form cavities at the boundary of the concrete due to factors such as irregularities, which may cause air bubbles in the concrete near the formwork, affecting the forming quality and reducing the bearing capacity of the pavement. fragile
