Description
Technical Field
The utility model relates to a rainwater well protection device used in stable water paving, and belongs to the technical field of paving construction of cement stabilized macadam base layers of urban roads.
Background
When the rubble basic unit was paved in municipal road cement stabilization at present, because the rainwater well is not under construction completely, mostly adopt to cover template or steel sheet and realize that the steady basic unit of water is overall paved, adopt template or steel sheet to cover the well head before the steady paving of water promptly, the steady material of well head water is clear away in the cutting again after the steady paving of water is accomplished.
After the cement stabilized base layer is paved, manually cutting and removing water stabilizing materials in the wellhead range, and filling and supplementing the water stabilizing materials at the periphery of the wellhead after the rainwater well is built. When the rainwater well is built in the mode and water stabilizing materials are filled, the water stabilizing materials are easy to be insufficient in compaction degree, the water stabilizing materials are loose and cannot be formed, and quality problems such as cracking of the periphery of the well mouth, explosion and the like are easy to occur after the vehicle is started in the later period.
Disclosure of Invention
In order to solve the problems and save cost, the utility model provides a rainwater well protection device used for water stable paving, which can improve the integral forming quality of a cement stabilized macadam base.
In order to achieve the purpose, the utility model adopts the technical scheme that the rainwater well protection device is used for stably paving water and comprises a steel casing 1, an in-well support 2, a thread draw hook 3 and a bolt fastening unit.
The middle of the bottom of the steel casing 1 is provided with a through hole; the threaded draw hook 3 penetrates through the through hole, and the inner part and the outer part of the middle of the bottom of the steel casing 1 and the threaded draw hook 3 are locked and fixed through the bolt fastening unit; the in-well support 2 is welded at the end part of the thread drag hook 3; the outer diameter of the steel casing 1 is equal to the inner diameter of the inner wall of the catch basin.
The bolt fastening unit comprises a first nut 4, a first gasket 5, a second nut 6 and a second gasket 7; the nut I4 and the gasket I5 are arranged in the middle of the bottom of the steel casing 1; a second nut 6 and a second gasket 7 are arranged outside the middle of the bottom of the steel casing 1; the steel casing 1 is fixed on the thread draw hook 3 through the bolt fastening unit.
The support 2 in the well is a steel rod, and the support 2 in the well is arranged along the circumferential direction of the steel casing 1.
The in-well support 2 and the threaded draw hook 3 are fixed by welding; the radius of the support 2 in the well is equal to the radius of the inner wall of the catch basin.
The first nut 4, the first gasket 5, the second nut 6 and the second gasket 7 are respectively positioned above and below the bottom surface of the steel casing 1 and are fixed with the threaded draw hook 3 through a threaded rod; the first nut 4, the first gasket 5, the second nut 6 and the second gasket 7 are screwed up and down through adjustment, so that the steel casing 1 is stable, and the support 2 in the well is arranged on the inner wall of the rainwater well through friction or in a lapping mode.
Compared with the prior art, the utility model has the following beneficial effects.
1. The utility model can be installed and removed only by manpower.
2. The utility model can effectively reduce the water stabilizing process of filling the periphery of the well chamber after the catch basin is built.
3. The utility model can effectively improve the integral forming quality of the cement stabilized macadam base.

In the figure: 1. the steel protects a section of thick bamboo, 2, support in the well, 3, screw thread drag hook, 4, nut one, 5, gasket one, 6, nut two, 7, gasket two.
Detailed Description
The utility model is described in detail below with reference to the accompanying drawings:
as shown in fig. 1, the rainwater well protection device for water stable paving comprises a steel casing 1, an in-well support 2, a thread draw hook 3, a first nut 4, a first gasket 5, a second nut 6 and a second gasket 7; the support 2 in the well and the thread draw hook 3 are fixed by welding; the first nut 4, the first gasket 5, the second nut 6 and the second gasket 7 are respectively positioned above and below the bottom surface of the steel casing 1 and are fixed with the threaded draw hook 3 through a threaded rod; the first nut 4, the first gasket 5, the second nut 6 and the second gasket 7 are vertically adjusted to tighten the support 2 in the fixing well, so that the steel casing 1 is stable.
As shown in figure 2, when in use, the steel casing 1 is manually moved to the position above a rainwater well to be covered, the height of the steel casing 1 is controlled by screwing the screw cap II 6 and the gasket II 7 below the bottom surface of the steel casing 1 upwards, and the steel casing 1 is propped against the inner wall of the rainwater well; screwing down a screw cap I4 and a gasket I5 above the bottom surface of the steel casing 1, and fixing the steel casing 1 and the thread draw hook 3; paving a cement stabilized macadam foundation after the installation is finished, taking out the device through a thread draw hook 3 after the paving is finished, manually moving the steel casing 1 to the next working surface, and circularly paving a subsequent cement stabilized macadam foundation according to the steps; the support 2 can effectively support and protect the steel casing 1 in the well.
