Problems solved by technology

All inspection wells are built on site with brick wells. Due to the difficulty in controlling the foundation treatment and the technical standards of brick wells, overall settlement and well damage are common, affecting vehicle driving, increasing vehicle loss and urban noise
Moreover, when the inspection shaft is damaged, on-site maintenance and on-site maintenance for a certain period of time are required, which affects the normal operation of traffic; when the road needs to be excavated as a whole, the inspection shaft is basically destroyed
In addition, because vehicles with large dynamic loads often pass through the manhole cover, the inspection well and its surrounding road surface and base layer will vibrate, and the pipes connected to the lower part of the inspection well will leak at the interface. The long-term effect of water leakage will affect the well wall. The solidity of the foundation soil around the inspection well, coupled with the long-term rolling of the inspection well by vehicles, over time, the rammed earth layer around the inspection well will easily collapse, and even affect the stability of the inspection well foundation

Embodiment 1

[0022] Embodiment one: if figure 1 and figure 2 As shown, the universal displacement compensation type prefabricated inspection well of the present invention includes a bottom plate 1, a first cylinder 2 and several second cylinders 3, the bottom plate 1 is arranged horizontally, the first cylinder 2 and all the second cylinders The centerlines of 3 coincide and the centerline is set along the vertical direction, all the second cylinders 3 are stacked up and connected sequentially from top to bottom, the lower end surface of the lowermost second cylinder 3 is connected to the upper end surface of the first cylinder 2, The lower end surface of the first cylinder 2 is fixed on the upper surface of the bottom plate 1, the first cylinder 2 and the bottom plate 1 are integrally manufactured, and the bottom plate 1, the first cylinder 2 and the second cylinder 3 are all prefabricated by reinforced concrete; At least two pipe passing through holes 4 are provided on the side of the ...

Embodiment 2

[0032] Embodiment 2: The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, the pipe joint includes a support tube 14, a mounting tube 15 and a rubber tapered sleeve 16. The support tube 14 is provided with two sections, and the two-section support tube 14 is installed in the through-hole 4 of the pipeline. The support tube 14 The outer wall is in sealing contact with the inner wall of the pipeline passing through hole 4, and there is an annular gap between the two support tubes 14, and the inner wall of the pipeline passing through hole 4 is provided with an annular groove, and the installation cylinder 15 is arranged in the annular groove, and the rubber tapered sleeve 16 The thicker end passes through the gap and is fixedly connected to the inner wall of the installation cylinder 15 , and the thinner end of the rubber conical sleeve 16 extends inwards to the inside of the first cylinder 2 .

Abstract

The invention discloses a universal displacement compensation type prefabricated inspection well which comprises a bottom plate, a first barrel and multiple second barrels. The bottom plate is arranged horizontally. The center line of the first barrel and the center lines of all the second barrels are arranged in the vertical direction. All the second barrels are connected in the manner of being sequentially piled up from top to bottom. The lower end face of the second barrel on the lowest portion is connected with the upper end face of the first barrel. The lower end face of the lower barrel is fixedly arranged on the upper surface of the bottom plate. The first barrel and the bottom plate are integrally manufactured. The bottom plate, the first barrel and the second barrels are prefabricated through reinforced concrete. According to the universal displacement compensation type prefabricated inspection well, used labor force and the road cost are effectively reduced, and the road site operation time is shortened; road surface unevenness caused by uneven sedimentation around the inspection well is avoided, the road evenness is increased, and construction quality is improved; and the maintenance time of the inspection well is effectively shortened, in addition, assemblies of the inspection well can be recycled and reutilized, the construction cost can be reduced, and sealing quality is fully improved.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering construction, in particular to a universal displacement compensation type prefabricated inspection well. Background technique [0002] Inspection wells are used in the turns, branches, drops, etc. of rainwater and sewage pipes for inspection and dredging. They are called inspection wells at school. All inspection wells are built on site with brick wells. Due to the difficulty in controlling the foundation treatment and the technical standards of brick wells, overall settlement and well damage are common, affecting vehicle driving, increasing vehicle loss and urban noise. Moreover, when the inspection shaft is damaged, on-site maintenance and on-site maintenance for a certain period of time are required, which affects the normal operation of traffic; when the road needs to be excavated as a whole, the inspection shaft is basically destroyed. In addition, because vehicles with large d...
