An integrated manhole cover module and its construction method

Abstract

The invention discloses an integrated inspection well lid module. The integrated inspection well lid module comprises a hollow cylindrical module body, a well lid base and a well lid matched with the well lid base, wherein the module body is formed by prefabricated concrete, the well lid base is embedded into the top face of the module body, the top face of the well lid is flush with the top face of the module body, the hole diameter of the hollow portion of the module body is matched with the inner diameter of an inspection well pipe, and a safety net hook is arranged on the hole wall of the module body. The inspection well lid and a well mouth system are optimally designed, prefabricated and integrated in a factory to form one module, the module integrates functions of a well mouth, the well lid and the protection net hook, is provided with an excellent stress structure and an interface, is additionally provided with hoisting and mounting rack holes, a grouting mouth and a grouting channel and has good pavement performance and attractive appearance on the outer surface.

Description

[0001] Technical field: [0002] The invention relates to an integrated inspection well cover module and a construction method thereof. [0003] Background technique: [0004] Traditional inspection well covers and wellhead systems are sporadic components, assembled on site, and most of them are manually operated, which leads to long construction work, low construction quality, frequent diseases, and high costs. The scars on the face of the city that will never be removed. [0005] For the structure and construction of traditional inspection wells, see figure 1 , 2 , there are two situations in the construction of traditional inspection wells, one is newly repaired inspection wells, see figure 2 , first construct and install the A2 pipe, which can be prefabricated pipe or brick pipe, then construct the A1 pipe, then backfill the C1 area, and then construct the manhole cover base 1 and install the manhole cover 2. Since the C1 area is close to the well body of the inspection...

[0004] Traditional inspection well covers and wellhead systems are sporadic components, assembled on site, and most of them are manually operated, which leads to long construction work, low construction quality, frequent diseases, and high costs. Scars that will never be removed on the face of the city

[0005] For the structure and construction of traditional inspection wells, see figure 1 , 2 , there are two situations in the construction of traditional inspection wells, one is newly repaired inspection wells, see figure 2 , first construct and install the A2 pipe, which can be prefabricated pipe or brick pipe, then construct the A1 pipe, then backfill the C1 area, and then construct the manhole cover base 1 and install the manhole cover 2. Since the C1 area is close to the well body of the inspection well, large road rollers cannot be too large It is close to the well body, so that the part close to the well body cannot be compacted. After the construction is completed and the traffic is opened, the passing vehicles are often rolled over, which is likely to cause the C1 area to loosen and collapse, and cannot form a good support for the periphery of the well body. When the vehicle is rolled, the manhole cover will be impacted The force and load are directly transmitted to the well wall, which may easily cause damage to the well wall

When traditional manholes are being maintained, see figure 1 First, use a crusher to excavate the C2 area, replace the broken manhole cover 2, the manhole cover base 1 and the damaged well wall A1, and then use cement mortar or concrete to backfill the C2 area. The noise is high and the construction progress is slow. The traffic can only be opened after the backfill reaches the set strength. The construction period is long, and it cannot solve the problem that the impact force and load on the manhole cover are directly transmitted to the well wall.
