Description
Technical Field
The utility model relates to the technical field of inspection well installation, in particular to a height-connecting structure of an inspection well.
Background
The rain and sewage inspection well is an inspection well which is arranged on a drainage pipeline system for inspecting and cleaning pipelines. And also plays a role in ventilation of the connecting pipe section and the pipeline system. The pipe sections between two adjacent wells are on the same straight line, so inspection wells are required to be arranged at the sections of the pipeline, the slopes, the intersections and the elevations, and the inspection wells are also required to be arranged on the overlong straight line pipe sections in sections (the section spacing is regulated according to the diameter of the pipeline, the type of rain and sewage). The traditional rain sewage inspection well mainly adopts a bricked form, and in recent years, more and more rain sewage inspection wells adopt a prefabricated reinforced concrete form due to popularization of assembly type buildings in the development of industry. However, the prefabricated reinforced concrete rain sewage well has a disadvantage that the prefabricated reinforced concrete rain sewage well is formed in a factory, and the specification and the size are difficult to change after leaving the factory. Once the site height of the construction site changes, the elevation of the wellhead of the precast reinforced concrete rain sewage well is difficult to adjust. The traditional mode of heightening the precast reinforced concrete rain sewage well mainly adopts a bricked mode, but the bricked position of heightening the rain sewage well often has fatal defects, namely, the heightened part is easy to break due to the action of upper load.

The utility model aims to overcome the defects of the prior art, and provides a height-connecting structure of an inspection well, which is characterized in that an extension pipe is arranged at the top of the inspection well, the top of the inspection well after the extension pipe is stacked is matched with the surface of the ground, then the extension pipe is fixedly connected with the inspection well through a connecting bolt, the height-connecting structure is higher than the traditional brickwork, the load on the upper part of the inspection well through the extension pipe is stronger in bearing capacity, the installation is convenient for constructors, and a large amount of construction time is saved.
The technical scheme who realizes above-mentioned purpose is a high structure that connects of inspection shaft, a plurality of screw holes have been seted up at the top of inspection shaft, connect high structure includes:
an extension tube arranged at the top of the inspection well, wherein a through hole is formed in the extension tube corresponding to the threaded hole; and
and the connecting bolt penetrates through the threaded hole and the through hole, and is in threaded connection with the threaded hole.
Furthermore, a nut is arranged at the end part of the through hole, and the connecting bolt is in threaded connection with the nut and penetrates through the through hole.
Further, the outer contour surface of the extension tube and the outer contour surface of the inspection well are positioned on the same vertical line.
Further, the inner wall of the extension tube and the inner wall of the inspection well are positioned on the same vertical line.
Further, the extension tube is of a concrete structure.
Further, the number of the extension pipes is confirmed according to the extension height of the inspection well.
Compared with the prior art, the utility model has the following beneficial effects:
through set up the extension pipe at the top of inspection shaft, pile up the top of the inspection shaft of extension pipe, the whole height of inspection shaft rises, later will through connecting bolt the extension pipe with inspection shaft fixed connection, compare in traditional mode of laying bricks increases, is fixed in through the extension pipe the upper portion load of inspection shaft has stronger tolerance, and to constructor simple to operate practices thrift a large amount of engineering time.
Drawings
Fig. 1 is a schematic structural view of a height-connection structure of an inspection well according to the present utility model.
Legend description: 1. an inspection well; 2. a tube extension; 3. a threaded hole; 4. and a through hole.
Detailed Description
The utility model will be further described with reference to the drawings and the specific examples.
Referring to fig. 1, a height-connecting structure of an inspection well, a plurality of threaded holes 3 are formed in the top of the inspection well 1, and the height-connecting structure comprises: an extension tube 2 arranged at the top of the inspection well 1, wherein a through hole 4 is formed in the extension tube 2 corresponding to the threaded hole 3; and the connecting bolt penetrates through the threaded hole 3 and the through hole 4, and is in threaded connection with the threaded hole 3.
In the present utility model, a preferred embodiment is: the inspection well 1 is reserved with a space for the threaded holes 3 before pouring, preferably, 4 threaded holes 3 are arranged at intervals at the top of the inspection well 1, and the threaded holes 3 are uniformly arranged along the top of the inspection well 1.
Furthermore, a nut is arranged at the end part of the through hole, and the connecting bolt is in threaded connection with the nut and penetrates through the through hole. Preferably, the through hole 4 is embedded with two nuts, the two nuts are respectively arranged on the top surface of the extension tube 2 and the bottom surface of the extension tube 2, the nuts are in threaded connection with the connecting bolts, so that the extension tube 2 cannot incline during installation, and the end surface of the outermost side of the nuts is flush with the end surface of the extension tube 2.
Further, the outer contour surface of the extension pipe 2 and the outer contour surface of the inspection well 1 are positioned on the same vertical line.
Further, the inner wall of the extension pipe 2 and the inner wall of the inspection well 1 are positioned on the same vertical line.
Further, the extension tube 2 is a concrete structure.
