Description

Precast concrete well cover with thickness adjusted through secondary pouring

Technical Field

The utility model belongs to the technical field of the precast concrete component, concretely relates to precast concrete well lid through secondary pouring thickness.

Background

The problems of the inspection well need to be fully considered during road construction and overhaul; after the manhole is constructed, asphalt or concrete is paved, generally, the pavement is finished to a height greater than the height of the manhole, and then the manhole is covered. In actual operation, the height of each inspection well is likely to have errors, when the well covers are installed, some well covers protrude out of the road surface, and some well covers are sunken in the road surface, so that the height difference generally exists; in addition, in the using process of the road, the problem of settlement caused by unstable foundation of the inspection well can occur, and the height difference between the well cover and the road surface can also occur. When the height difference is too large, the normal passing of pedestrians is influenced, the problems of tripping, foot-spraining and the like are easily caused, the motor vehicles and the non-motor vehicles in the past are bumpy, and in severe cases, the situations of tire burst and the like are possibly caused; in addition, because the existence of difference in height, the vehicle of coming and going forms long-term, high frequency impact to the well lid in jolting for the well lid life-span shortens, with the well lid around the fit clearance grow and rock easily, when serious, thereby the well lid can break away from the inspection shaft even when suffering the impact and lose the protection to the well head, very dangerous.

In recent years, in order to avoid the problem that the cast iron manhole cover is stolen, the precast concrete manhole cover is adopted, the manhole cover made of steel fiber concrete materials has good supporting strength, but the required thickness is large, a large wellhead space is usually reserved, and therefore the height difference possibly caused by the precast concrete manhole cover is large.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a highly variable, strong adaptability pour the precast concrete well lid that comes regulation thickness through the secondary.

In order to solve the technical problem, the utility model discloses a precast concrete well cover with thickness adjusted by secondary pouring, which comprises a circular well cover body and a bottom cover plate, wherein the shapes of the well cover body and the bottom cover plate are matched, a screw rod is vertically arranged at the center of the bottom of the well cover body, and a threaded sleeve matched with the screw rod is arranged in the middle of the bottom cover plate; the bottom cover plate can be fixed on the lower side of the well lid body through a screw rod and a threaded sleeve which are in threaded connection and can move up and down.

Preferably, a plurality of pouring holes for pouring concrete are formed in the bottom cover plate.

Preferably, the bottom of the well lid body is provided with a plurality of radially or annularly arranged grooves or bulges.

Preferably, the bottom cover plate edge has an ascending hem, makes to form between well lid body and the bottom cover plate and holds the chamber, holds the chamber and pours the hole intercommunication.

Preferably, the height of the folded edge is not more than the total thickness of the well lid body and the bottom cover plate.

Preferably, the well lid body is made of steel fiber concrete.

Preferably, the bottom cover plate is made of hard plastic or metal material.

Preferably, the support steel plate that sets up is buried underground in the well lid body, and screw rod one end is connected fixedly with the support steel plate.

Preferably, the support steel plate is a cross-shaped steel plate.

The utility model discloses a pour the precast concrete well lid that comes regulation thickness through the secondary, with low costs, thickness is adjusted conveniently to pour through the concrete secondary and stereotype thickness, overall structure is firm, and is fixed good with the supporting effect, long service life.

Drawings

Fig. 1 is a schematic structural view of a precast concrete well cover in which the thickness is adjusted by secondary casting.

The reference numbers in the figures are: the method comprises the following steps of 1-well lid body, 2-bottom cover plate, 3-screw rod, 4-thread sleeve, 5-pouring hole, 6-folded edge, 7-containing cavity and 8-supporting steel plate.

Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Example 1

As shown in fig. 1, the precast concrete well cover with the thickness adjusted by secondary pouring comprises a circular well cover body 1 and a bottom cover plate 2, wherein the shapes of the well cover body and the bottom cover plate are matched, a screw rod 3 is vertically arranged at the center of the bottom of the well cover body, and a threaded sleeve 4 matched with the screw rod is arranged in the middle of the bottom cover plate; the bottom cover plate can be fixed on the lower side of the well lid body through a screw rod and a threaded sleeve which are in threaded connection and can move up and down.

And the bottom cover plate is provided with a plurality of pouring holes 5 for pouring concrete.

The bottom of the well lid body is provided with a plurality of radially or annularly arranged grooves or bulges. The groove or the protrusion can enable the well lid body to be combined with newly poured concrete more tightly when the well lid is poured for the second time.

The bottom cover plate edge has ascending hem 6, makes to form between well lid body and the bottom cover plate and holds chamber 7, holds the chamber and pours the hole intercommunication.

The height of the folded edge is not more than the total thickness of the well lid body and the bottom cover plate.

The well lid body is made of steel fiber concrete.

The bottom cover plate is made of hard plastics or metal materials.

The supporting steel plate 8 horizontally arranged is buried in the well lid body, and one end of the screw rod is fixedly connected with the supporting steel plate.

The supporting steel plate is a cross-shaped steel plate. The cross-shaped steel plate can save materials while achieving the supporting effect, and can also ensure that concrete above and below the supporting steel plate can be kept in sufficient connection, so that the integrity is stronger.

During the use, estimate the well lid thickness that needs earlier, make the end cover board place up, adjust the gross thickness of well lid body and end cover board through rotatory end cover board, then to holding the intracavity concreting (the building site can with the concrete, it can not necessarily be steel fibre concrete), wait it completely to solidify, can put into use.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
