Asphalt high-pressure joint filling device for water conservancy construction

Abstract

The invention discloses an asphalt high-pressure joint filling device for water conservancy construction, and belongs to the technical field of water conservancy construction. The asphalt high-pressure joint filling device comprises a base body assembly, a material box is arranged on a frame, and the material box is connected with a material injection pipe through a material pipe; a crack trackingassembly which comprises a discharging head movably inserted into an inner cavity of the material injection pipe and a fixing ring fixedly arranged on the outer wall of the material injection pipe ina sleeving mode; a guide assembly; the discharging head of the filler extends into a crack with a large span, the tracking roller abuts against the inner wall of the crack through the supports on thetwo sides of the discharging head, the elastic telescopic rod keeps the tracking roller in contact with the inner wall of the crack all the time along with movement of the tracking roller, and therefore the discharging head moves forwards in the crack direction; the passing limiting shafts are all compressed and kept in a contraction state, a track matched with the crack is formed on the bottom face of the rectangular frame, then the rectangular frame moves back and forth along the track, the irregular large-span crack can be rapidly and accurately filled, the operation difficulty is lowered,and the construction efficiency is improved.

Description

Technical field[0001]The invention relates to the technical field of water conservancy construction, in particular to an asphalt high-pressure joint filling device for water conservancy construction.Background technique[0002]A water conservancy project is a project built for the purpose of controlling and arranging surface water and groundwater in the natural world to achieve the purpose of eliminating harm and benefiting. Also called water engineering. Water is a precious resource indispensable for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water volume to meet the needs of people for water resources in life and production. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferry channels, raft channels, and fish channels to achieve thei...

Problems solved by technology

[0003] After the construction of water conservancy projects, the road surface often has cracks due to the rolling of heavy vehicles or its own structural strength is not high, especially for some cracks with large spans. The current equipment is to crack from the top of the crack Filling in the middle of the filling, due to the irregular shape of the extension of the crack, it is not only easy to cause the filling to not enter the crack accurately, but also increase the difficulty of operation for the construction personnel. It is necessary to constantly adjust the position of the filling, which reduces the filling quality and construction efficiency. , for this reason, we propose a bitumen high-pressure joint filling device for water conservancy construction
