A kind of reserved installation mechanism for manhole wellhead in asphalt pavement construction

Abstract

The invention discloses a manhole wellhead reserved installation mechanism for asphalt pavement construction, comprising an installation ring and a manhole cover with two clamping grooves on the side wall, the installation ring is provided with two chutes, two installation cavities and two There are two sliding grooves, both of which are provided with blocking mechanisms. Both of the blocking mechanisms extend into the opposite clamping grooves on the manhole cover and abut against their inner side walls. Both the sliding grooves are provided with A driving mechanism, the two driving mechanisms both extend into the opposite installation cavities and are slidably connected with them, the top ends of the two driving mechanisms both extend into the opposite blocking mechanisms and abut against their inner walls, and the two installation cavities Both are provided with a rotating mechanism, and the top of the mounting ring is provided with two pulling mechanisms. The present invention has a reasonable structure design, can effectively limit and fix the installed manhole cover, and is generally difficult for uninformed persons to remove the manhole cover, ensuring that the manhole cover is not easily lost.

Description

technical field [0001] The invention relates to the technical field of manhole installation, in particular to a reserved installation mechanism for manhole wellheads in asphalt pavement construction. Background technique [0002] A manhole is an underground space where urban underground pipelines are transferred and controlled. Its ground entrance and exit are called manhole mouths or manholes. Manholes are usually covered by manhole covers. In cities, all public water supply, sewage canals, telephone lines, and optical fiber networks may pass through. The underground passage connection under the manhole. [0003] In the prior art, when installing a manhole cover, a mounting ring is first pre-installed on the ground, and then a manhole cover with a diameter slightly smaller than the mounting ring is installed on the mounting ring. Although the installation operation is simple, the manhole cover is very difficult to install. It is easy to be removed, which can easily lead to...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when installing the manhole cover, an installation ring will be pre-installed on the ground first, and then the manhole cover with a diameter slightly smaller than the installation ring will be set on the installation ring. It is simple, but the manhole cover is easy to be removed, and it is easy to cause the manhole cover to be lost, and there is a big potential safety hazard. However, a reserved installation mechanism for the manhole head of the asphalt pavement construction is proposed, which can effectively carry out the installation of the manhole cover installed. The ground limit is fixed, and it is difficult for uninformed personnel to remove the inspection well cover to ensure that the inspection well cover is not easy to lose
