Highway bridge roadbed pavement auxiliary construction device and construction method thereof

Abstract

The invention relates to the technical field of roadbed pavement auxiliary construction, in particular to a highway bridge roadbed pavement auxiliary construction device and a construction method thereof. The auxiliary construction device comprises a first mold and a second mold. The first mold is in a cuboid shape, a cavity is formed in the upper end of the first mold, the first mold and the second mold are consistent in shape, and the first mold and the second mold are symmetrically arranged; the auxiliary construction device further comprises a repairing mold, an electric push rod and a controller. The repairing mold is located between the first mold and the second mold, the section shape of the repairing mold is consistent with that of the first mold, and one side face of the repairing mold makes contact with the side face of the first mold; according to the auxiliary construction device, raw materials are poured into the upper ends of the first mold, the second mold and the repairing mold to form a roadbed pavement, and then the repairing mold is driven by an electric push rod to be separated from the first mold and the second mold for matching, so that a worker can conveniently take out the formed roadbed pavement, and the construction efficiency of the highway bridge roadbed pavement is improved.

Description

technical field [0001] The invention relates to the technical field of subgrade and pavement auxiliary construction, in particular to an auxiliary construction device and construction method for highway bridge subgrade and pavement. Background technique [0002] Highway lines pass through rivers, harbors, lakes, reservoirs, irrigation canals and other waters, or across deep valleys with large height differences, or across other traffic lines. Bridges need to be erected in order to maintain smooth traffic; sometimes viaducts are required in bustling urban areas The highway bridge project includes the main body of the bridge and the auxiliary engineering facilities in the overall bridge position; there are many auxiliary engineering facilities, such as bank revetments, diversion dikes and other structures for regulating water flow in order to maintain the stability of the bridge at the bridge. Approach bridges connected by highways, railings on bridges to prevent wheel collisi...

[0002] Highway lines pass through rivers, harbors, lakes, reservoirs, irrigation canals and other waters, or across deep valleys with large height differences, or across other traffic lines. Bridges need to be erected in order to maintain smooth traffic; sometimes viaducts are required in bustling urban areas The highway bridge project includes the main body of the bridge and the auxiliary engineering facilities in the overall bridge position; there are many auxiliary engineering facilities, such as bank revetments, diversion dikes and other structures for regulating water flow in order to maintain the stability of the bridge at the bridge. Approach bridges connected by highways, railings on bridges to prevent wheel collisions, sidewalk railings to ensure pedestrian safety, signs on bridges, navigation signs under bridges, and bridge deck lighting equipment; as an important part of highway bridges, roadbeds The construction of the roadbed is particularly important; however, due to the lack of existing technology, after the roadbed is poured and formed, the roadbed is engaged and pressed down under the action of atmospheric pressure and gravity, so that it is laborious to take out the formed roadbed, and the construction of the roadbed road surface Efficiency suffers;

[0003] For example, a Chinese patent with the application number CN201810537602.9 discloses a highway bridge embankment pavement and its construction method, including a foundation, a soil base, a first sand cushion, a second sand cushion, a stable layer, an upper The base layer and the surface layer, the construction method comprises the following steps: constructing a soil base layer on the foundation, inserting foundation stabilizing bars in the soil base layer, laying the first sand cushion layer on the soil foundation layer, constructing a gabion cage on the sand cushion layer, The second sand cushion layer is laid around the gabion cage, the special-shaped waterproof reinforcement layer is laid on the second sand cushion layer, the special-shaped waterproof reinforcement layer is shaped and supported by the reinforcement plate, and the upper base layer is laid on the stable layer; A stable layer with gabion cages is added between the base and the upper base, and the erosion of the groundwater on the traditional base and upper base is alleviated by means of dredging and plugging; Get up, and then carry out the construction, the subgrade after construction still faces the situation of taking out the laborious and laborious situation, which affects the construction efficiency of the highway bridge subgrade pavement, and thus causes the limitation of the scheme
