First-embankment and second-well construction method

Abstract

The invention belongs to the technical field of municipal engineering, and particularly provides a first-embankment and second-well construction method. The first-embankment and second-well construction method comprises the following steps of constructing an embankment, a pipeline and a well bottom; additionally installing a well bottom cover plate at a well bottom closing opening, and measuring and positioning the center of the well bottom cover plate; constructing a roadbed and a pavement base layer; measuring and positioning the center of the well; drilling and digging a well hole; taking the well bottom cover plate out; cleaning the well bottom closing opening; additionally paving cement mortar; hoisting a well body, and measuring the elevation of the well body; mounting an elevation adjusting block; hoisting a well lid seat; mounting an inner mold between the well body and the well lid seat; filling the periphery of the well body with a filler below the top of the well body; mounting an outer mold from the pavement base layer until the top of the well lid seat; pouring concrete; and mounting a well lid. The problems that a well is prone to being damaged, the periphery of the well is uneven in settlement, driving safety and driving comfort are affected, and the maintenance frequency and maintenance cost are increased are solved; and the pipeline is not prone to being blocked, the roadbed bearing capacity of the periphery of the well is good, the settlement amount of the well and the periphery is small, the service life of the well and the surrounding road is prolonged, and the driving comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to a construction method of embankment first and then well. Background technique [0002] All kinds of pipeline inspection wells in municipal engineering are weak links in the quality of municipal road engineering and driving (pedestrian) safety. Inspection wells (referred to as: wells) usually adopt the process of raising the well by laying bricks for many times (also called the first well and then embankment process) After the well is built to a certain height, the subgrade is filled. Large-scale compaction equipment is not easy to approach the surrounding of the well. The embankment around the well has a low degree of compaction. When approaching, the well is often damaged, the well wall is damaged, and the subgrade filling is carried by a large amount of rainwater. People in pipelines and other situations occur from time to time, causing settlement of t...

Problems solved by technology

[0035] The purpose of the construction method of a dike first and then a well provided by the present invention is to overcome the problems that the inspection wells of various municipal pipelines are easily damaged, and the surroundings of the wells are unevenly settled, which affects driving safety and driving comfort, and increases maintenance frequency and maintenance costs; The second purpose is to overcome the conventional construction technology of municipal wells. All kinds of pipes are easily blocked by construction waste. Cleaning up waste is inconvenient and expensive. When cleaning is not thorough, it will affect drainage, sewage discharge and use functions.
