Wellhead shaping barrel for pavement construction

Abstract

The invention discloses a wellhead shaping barrel for pavement construction. The wellhead shaping barrel for pavement construction comprises a movable frame body, an arc-shaped vertical plate is arranged outside the movable frame body, a check block is arranged outside the arc-shaped vertical plate in a sleeving mode, the movable frame body is mainly composed of a left frame body and a right frame body, and the left frame body and the right frame body are connected through a guide column. Connecting ends are arranged on one side of the middle of the top of the left frame body and one side of the middle of the top of the right frame body respectively, the connecting end on the right frame body is movably connected with a first connecting rod through a first pin shaft, the connecting end on the left frame body is movably connected with a second connecting rod through a first pin shaft, and the first connecting rod and the second connecting rod are movably connected through a second pin shaft. A handle ring is arranged on one side of the top of the first connecting rod. The vertical position can be adjusted through the arranged movable frame body, the construction efficiency is improved, the well mouth can be shaped through the arranged arc-shaped vertical plate, concrete, asphalt and the like can be prevented from flowing into the well through the arranged check block, the check block can restore deformation after being rolled, secondary use is not affected, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of road surface construction, in particular to a well head shaping barrel for road surface construction. Background technique [0002] At present, with the rapid development of the city, municipal engineering is also advancing in an all-round way, especially the construction of municipal roads, which is an important indicator of the rapid development of a city. In the process of municipal road construction, drainage and sewage wells, cable maintenance wells, gas maintenance wells, etc. are generally dug first, and then the underlying road surface and asphalt pavement are laid. The reserved wellhead needs to be blocked with a baffle to complete the finalization to prevent concrete, asphalt, etc. from flowing into the well, so as to facilitate the construction of drainage and sewage wells, cable maintenance wells, gas maintenance wells, etc. in the later stage. Most of the existing wellhead shaping methods fo...

AI Technical Summary

Problems solved by technology

Most of the existing wellhead shaping methods for road construction use hard circular baffles to place on the base road at the wellhead position. After the bottom pavement is laid, the circular baffles are removed and replaced with new circular baffles The board height is slightly higher than the previous one) to complete the asphalt pavement paving, which makes the pavement construction very troublesome and low in construction efficiency; the hard circular baffle plate after rolling is prone to deformation, resulting in inaccurate roundness of the reserved wellhead. Affect the placement of well covers; at the same time, the hard circular baffles that have been deformed are difficult to use again, which increases construction costs
