Abstract
According to the method for installing the well cover of the roadway, after the implementation of the road base layer is finished, the unloading plate is excavated and poured reversely, the flange plate is embedded at the same time, the well head is provided with the transition well cover before the construction of the lower asphalt layer, the elevation of the transition well cover is flush with the lower asphalt layer, and then the lower asphalt layer is paved; and after paving the lower surface layer of the asphalt, removing the transitional well cover, then installing the well base and the well cover, and paving the upper surface layer of the asphalt. Simple structure is practical, and the installation is firm, because the effect of off-load board, can effectively resist the sinking that self inhomogeneous settlement and external load produced down, improves the structural strength and the stability of inspection shaft, reduces the rate of reprocessing, saves the expense of reprocessing, reduces the later maintenance cost.
Description
Technical Field
The invention belongs to the technical field of road construction, and particularly relates to a method for installing a well cover of a roadway.
Background
Urban road surface is distributing a large amount of inspection shafts, and traditional well lid installation mainly fixes the well lid with mortar or fine aggregate concrete, produces the level of well lid and vertical direction's displacement easily in the use, and the later stage easily produces inhomogeneous sinking, brings the potential safety hazard for normal road traffic, causes destruction for the facility below the well lid, can cause the traffic accident, threatens people's security of lives and property.
Disclosure of Invention
In order to solve the problems, the invention discloses a method for installing a well cover of a roadway, which is simple and practical in structure, firm in installation and free of settlement.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a method for installing a well lid of a roadway comprises the following steps:
the first step is as follows: after the implementation of the road base layer is finished, reversely excavating and pouring the unloading plate, and simultaneously embedding a flange plate above the junction of the unloading plate and the base layer;
the second step is that: installing a transition well cover on a well head before constructing the lower asphalt surface layer, leveling the elevation of the transition well cover with the lower asphalt surface layer, and then paving the lower asphalt surface layer;
the third step: and after paving the lower surface layer of the asphalt, removing the transitional well cover, then installing the well base and the well cover, and paving the upper surface layer of the asphalt.
As an improvement of the invention, step (1) arranges a geogrid with the width of 1 m between the unloading plate and the surface layer.
As an improvement of the invention, in the step (2), a transition well cover is installed at the well mouth during the construction of the lower asphalt layer, and the elevation of the transition well cover is flush with the upper asphalt layer.
As an improvement of the invention, in the step (3), the reserved bolt holes of the flange plate need to be protected before the well base is installed.
The invention has the beneficial effects that:
according to the method for installing the well lid of the roadway, the unloading plate is poured in a reverse excavation mode after the implementation of the road base layer is finished, the flange plate is embedded in advance, the structure is simple and practical, the installation is firm, the uneven settlement of the unloading plate and the settlement generated under the external load can be effectively resisted under the action of the unloading plate, the structural strength and the stability of the inspection well are improved, the repair rate is reduced, the repair cost is saved, and the later maintenance cost is reduced.

FIG. 1 is a schematic structural diagram of the present invention.
List of reference numerals:
1. road base, 2, unloading board, 3, flange plate, 4, geogrid.
Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in the figure, the method for installing the well lid of the roadway comprises the following steps of:
1. the thickness H of the unloading plate is the same as that of the upper base layer, reverse excavation construction is carried out, and the base layer of the plate bottom is smooth and compact;
2. reversely excavating a base layer for construction by the unloading plate, and arranging a geogrid with the width of 1 m between the unloading plate and the surface layer;
3. pre-burying a flange plate during casting of the unloading plate;
4. the shaft is built to the bottom of the pavement structure layer, and is covered by the steel plate with the same caliber, and then the base course is paved, so that the base course is conveniently rolled and the road building material is prevented from falling into the well. After the construction of the current base course, heightening the well body, constructing the upper base course after the steel plate is covered, and the like. Installing a transition well cover at a well mouth during construction of the lower asphalt layer, wherein the elevation of the transition well cover is flush with that of the upper asphalt layer, removing the transition well cover after paving, then installing a well base well cover, and paving an upper asphalt layer;
5. the flange plate is pre-embedded during casting of the unloading plate, and the flange plate is tightly connected with concrete in the pre-embedding process, so that the concrete is vibrated tightly;
6. the reserved bolt holes of the flange plate need to be protected before the well base is installed, so that sundries are prevented from entering;
7. well head installation transition well lid when the lower surface course of pitch is under construction, transition well lid elevation flushes with pitch upper surface course, removes transition well lid after having paved, then installation well seat well lid, pave the surface course under the pitch.
After the traditional slurry well lid is installed, settlement can be easily generated after long time use, and after the process disclosed by the invention is adopted, the condition that settlement is not generated and displacement is not easy to generate can be ensured for a long time due to the action of the unloading plate, so that the well lid is firmer than the well lid installed by the traditional construction process.
The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features.
