Description
Technical Field
The utility model belongs to the technical field of the precast concrete component, concretely relates to precast concrete well lid with adjustable.
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 addition, because the well lid is mostly cast by iron and has a certain economic value, the well lid also becomes a target aimed by a part of lawless persons, and how to reduce the value of the well lid and improve the adaptability of the well lid becomes a problem worthy of research.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a height is variable, strong adaptability's adjustable precast concrete well lid.
In order to solve the technical problem, the utility model discloses an adjustable precast concrete well cover, which comprises a concrete poured well cover body and a base, wherein the base is annular, the bottom of the well cover body is provided with a boss, and the inner side space of the base is matched with the boss;
a plurality of groups of counter bores are uniformly arranged on the outer edge of the base along the circumferential direction, and each group of counter bores comprises 2-4 counter bores arranged from top to bottom; and a row of mounting holes are formed in the side wall of the boss corresponding to the counter bores.
Preferably, a horizontally disposed support steel plate is embedded in the boss.
Preferably, the supporting steel plate is a cross-shaped steel plate or a sheet-shaped steel plate with a cross-shaped hole in the middle.
Preferably, the base outer edge is aligned with the well lid body outer edge.
Preferably, a threaded sleeve is arranged in the mounting hole.
Preferably, the threaded sleeve is welded and fixed with the support steel plate.
Preferably, a gasket is arranged between the upper edge of the base and the well lid body.
Preferably, the gasket is a rigid plate or a hard rubber having a cushioning effect.
Preferably, the well lid body is made of steel fiber concrete.
Preferably, a plurality of air holes are arranged on the well lid body.
The utility model discloses a precast concrete well lid with adjustable, with low costs, height-adjustable, the well lid body is fixed and is supported effectually, can also adjust once more after using a period inspection shaft to subside, has better result of use.
Drawings
Fig. 1 is a schematic view of a construction of an adjustable precast concrete well cover.
The reference numbers in the figures are: 1-a well lid body, 2-a base, 3-a boss, 4-a counter sink, 5-a mounting hole, 6-a support steel plate, 7-a thread bush, 8-a gasket and A-a bolt.
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 adjustable precast concrete well cover comprises a well cover body 1 cast by concrete and a base 2, wherein the base is annular, a boss 3 is arranged at the bottom of the well cover body, and the inner side space of the base is matched with the boss; the well lid body can be circular or square, and then the base also is circular or square that suits.
A plurality of groups of counter bores are uniformly arranged on the outer edge of the base along the circumferential direction, and each group of counter bores comprises 2-4 counter bores 4 arranged from top to bottom; and a row of mounting holes 5 are formed in the side wall of the boss corresponding to the counter bores. Through with the mounting hole with the high counter sink of difference corresponding fixed, can adjust the height of well lid body.
And a horizontally arranged supporting steel plate 6 is embedded in the boss.
The supporting steel plate is a cross-shaped steel plate or a sheet-shaped steel plate with a cross-shaped hole in the middle. The cross-shaped steel plate or the circular steel plate with the cross-shaped hole in the middle can save materials when the supporting effect is achieved, and the concrete above and below the supporting steel plate can be kept in sufficient connection, so that the integrity is stronger, and the concrete pouring is more convenient.
The outer edge of the base is aligned with the outer edge of the well lid body.
And a threaded sleeve 7 is arranged in the mounting hole.
The threaded sleeve is welded and fixed with the supporting steel plate, so that the threaded sleeve and the pressure applied to the positions nearby the threaded sleeve can be uniformly distributed on the well lid body through the supporting steel plate.
A gasket 8 is arranged between the upper edge of the base and the well lid body.
The gasket is a rigid plate or hard rubber with a buffer effect. The gasket can play the supporting role, alleviates the pressure that mounting hole and bolt received.
The well lid body is made of steel fiber concrete.
A plurality of air holes are formed in the well lid body.
When the manhole cover is used, firstly, the integral height of the required manhole cover body and the base is estimated, the mounting hole is judged to be aligned to the countersunk head with the height, a gasket with proper thickness is arranged between the upper surface of the base and the manhole cover body (if hard rubber is selected, the thickness is slightly larger than the gap thickness), and then the corresponding countersunk head hole and the mounting hole are fixed through a bolt A, so that the manhole cover body and the base are fixed; then the well lid body and the base are placed on a well mouth.
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.
