Abstract

The utility model provides a prefabricated inspection well consisting of an inspection well body, an inspection well cover, a base, a pipeline cable port, a positioning table and an inspection well cover support. The inspection well cover is an individual assembly; the inspection well cover support, the pipeline cable port and the inspection well are in an entire assembly; a step above the inspection well body is the inspection well cover support; the internal diameter of the step is matched with the external diameter of the inspection well cover; the height of the step is consistent to the thickness of the inspection well cover; the pipeline cable port is arranged at the bottom of the inspection well body; the base and the positioning table are combined to be one assembly; the positioning table is arranged on the base; and the external diameter of the positioning table is consistent to the internal diameter of the bottom of the inspection well body. In a special die, three assemblies are respectively cast by reinforced concrete, and transported to a construction field for construction, so as to obtain an entire inspection well.

Description

A kind of prefabricated inspection shaft

Technical field

The utility model relates to a kind of prefabricated inspection shaft, specifically refers to employed upper and lower waterpipe inspection shaft and cable inspection shaft in the municipal construction.

Background technology

At present, all there are three big defectives in the numerous inspection shafts on the road of city: the 1st, inspection shaft lid is urib founding, because of the time have that well lid is stolen to stay the life trap to road; The 2nd, all inspection shafts are brick well and embody a construction, and handle the gene basis and brick well body technique standard is difficult to control, and common bulk settling and well body are damaged, influence vehicle ', increase vehicle loss and city noise; 3, no matter be metal or nonmetal well lid, its lid holder all is bonding through cement and well body, the time have lid holder and well body to break away from generation, influence traffic, increase municipal maintenance cost.

Summary of the invention

The utility model provides a kind of prefabricated inspection shaft, promptly according to the geology and the road technical standard batch production configuring technical key element in city, behind the independent assembly of reinforced concrete prefabricated one-tenth, is transported to the job site and is assembled into integrated inspection well.

The technical scheme of the utility model is: prefabricated inspection shaft is made up of inspection shaft body, inspection shaft lid, pedestal, underground cable mouth, positioning table, the holder of inspection shaft lid.The inspection shaft lid is stand-alone assembly, the holder of inspection shaft lid, underground cable mouth, the as a whole assembly of inspection shaft body, and it is the holder of inspection shaft lid that there is step inspection shaft body top, its internal diameter and inspection shaft lid external diameter coincide, shoulder height and inspection shaft lid consistency of thickness, the underground cable mouth is in inspection shaft body bottom; Pedestal and positioning table are an assembly, and positioning table is on pedestal, and the positioning table external diameter is consistent with inspection shaft body bottom internal diameter.

In the mould of special use,, be transported to the job site assembling and be complete inspection shaft with steel concrete three assemblies of casting respectively.

The beneficial effect of the utility model is: according to geology and road technical standard configuring technical key element, prevent that sedimentation or well body are damaged; Holder of inspection shaft lid and the integral cast of inspection shaft body stop to break away from; Batch production is produced, and reduces construction cost and the holding time that reduces the job site.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is each assembly generalized section before the utility model assembling;

Fig. 2 is the utility model assembling back generalized section.

Among the figure: 1, inspection shaft body, 2, inspection shaft lid, 3, pedestal, 4, the underground cable mouth, 5, positioning table, 6, the holder of inspection shaft lid.

The specific embodiment:

In the embodiment in figure 1, prefabricated inspection shaft is by inspection shaft body 1, and inspection shaft covers 2, and 3 three assemblies of pedestal constitute.It is inspection shaft lid holder 6 that there is step the top of inspection shaft body 1, and the bottom is reserved with underground cable mouth 4; Pedestal 3 diameters greater than inspection shaft body 1 base diameter to ensure enough anti-sedimentation bearing capacity; Be provided with positioning table 5 above the pedestal; The diameter of positioning table 5 and inspection shaft body 1 bottom internal diameter coincide, and location accurate, also can prevent to cause 1 displacement of inspection shaft body because of the external force effect when guaranteeing to install; It is same body structure with inspection shaft body 1 that inspection shaft covers holder 6, has eliminated the hidden danger that holder 6 of inspection shaft lid and inspection shaft body 1 break away from.

According to geology and road technical standard; After configuring the technology essential factor of inspection shaft; Make three moulds of stand-alone assembly separately respectively according to technical requirements,, make three steel mesh reinforcements of stand-alone assembly separately by the arrangement of reinforcement requirement; Steel mesh reinforcement is placed in the mould, get final product with concrete pouring, after solidifying, maintaining.

In the embodiment of Fig. 2, be transported to the job site to prefabricated inspection shaft split assembly, in ready-made inspection shaft hole; Settle pedestal 3 earlier; Again according to pipeline trend with behind the underground cable mouth 4 alignment tube line positions, the positioning table 5 on the pedestal 3 is inserted in inspection shaft body 1 bottom, at last the inspection shaft lid 2 inspection shaft lid holder 6 of packing into; Promptly accomplish the assembling of an integrated inspection well, saved a large amount of on-site construction times.

Claims

1. prefabricated inspection shaft; It is characterized in that: inspection shaft is made up of inspection shaft body, inspection shaft lid, pedestal, underground cable mouth, positioning table, the holder of inspection shaft lid, and the inspection shaft lid is stand-alone assembly, the holder of inspection shaft lid, underground cable mouth, the as a whole assembly of inspection shaft body; It is the holder of inspection shaft lid that there is step inspection shaft body top; Its internal diameter and inspection shaft lid external diameter coincide, shoulder height and inspection shaft lid consistency of thickness, and the underground cable mouth is in inspection shaft body bottom; Pedestal and positioning table are an assembly, and positioning table is on pedestal, and the positioning table external diameter is consistent with inspection shaft body bottom internal diameter.
