Heavy traffic road inspection well loop and construction method thereof

Abstract

The invention discloses a heavy traffic road inspection well loop and a construction method thereof. The well loop comprises an inspection well bottom portion, an inspection well middle portion, an inspection well upper portion, a well base, a nodular cast iron well lid and the like. A well wall is arranged between the inspection well bottom portion and a steel inner die and provided with a pipeline butt joint hole. The well base is installed on peripheral concrete for synchronously pouring a well base installation system. The nodular cast iron well lid is arranged at a well mouth of the upperside of the well base. The inspection well middle portion and the inspection well upper portion are internally provided with well loop reinforcement cages, and concrete is poured. A bottom base layeris arranged outside the inspection well bottom portion. A middle base layer is arranged outside the inspection well middle portion. An asphalt layer is arranged outside the inspection well upper portion. Through the technology, the obtained inspection well loop is large in bearing capacity, and the stability of the well wall in the construction process is ensured; the rapid positioning and fixingin the installation period of the well base are accelerated, and the construction method of the well loop is simple and convenient to implement, high in production efficiency and suitable for heavy traffic roads; due to the hollow design of arc-shaped concrete modularized bricks, resources can be saved.

Description

Technical field [0001] The invention relates to a road inspection well circle, in particular to a heavy traffic road inspection well circle and a construction method thereof. Background technique [0002] With the needs of economic and social development, in order to ensure the orderly operation of urban life, underground urban pipelines are widely distributed on both sides of the road, and inspection wells are used as underground pipelines for maintenance and maintenance to ensure the normal operation of underground pipelines. Its bearing capacity, settlement The control requirements are relatively strict. [0003] The manhole cover part of the inspection manhole is located on the road surface and is often impacted by passing vehicles, which can easily cause the manhole cover to sink and the pavement around the manhole cover to crack and other diseases, which will have a great impact on driving safety, the beautiful road surface, and the appearance of the city. The problem is heav...

AI Technical Summary

Problems solved by technology

Although the cast-in-place concrete well ring has good bearing performance and is not prone to settlement of the well ring, but the cast-in-place concrete is time-consuming and requires very strict construction quality control, so this form of inspection well is not used in general projects

The plastic inspection well circle has a small dead weight, and its material properties do not require anti-corrosion treatment, but it is greatly affected by the groundwater level. Excessive accumulation of rainwater will cause the well circle to float up. In addition, affected by the processing technology, the plastic inspection well Generally, the diameter is small and the scope of use is limited

The traditional brick inspection well ring is not suitable for the current development concept because of its poor corrosion resistance and sealing performance, coupled with the damage of clay bricks to land resources.

[0004] To sum up, although there are various forms of well circles in inspection wells at present, their respective defects are very prominent. It is proposed to seek a well circle structure based on brick inspection wells, which can protect the environment, increase the bearing capacity of the well circle structure, and reduce the settlement and The heavy-duty traffic road inspection well circle and its construction method are very important for the surrounding road surface settlement phenomenon
