Prefabricated assembled reinforced concrete rectangular inspection shaft chamber

Abstract

The invention discloses a prefabricated assembled reinforced concrete rectangular inspection shaft chamber. The rectangular inspection shaft chamber is formed by assembling a plurality of wall boards. The inspection shaft chamber has the advantages that: 1, the rectangular inspection shaft chamber is divided into a plurality of flat plates and can be manufactured by a simple model on a platform during production, the model and the production process are simplified and the manufacturing cost is reduced; 2, each block has light weight and small space, is convenient to transport and can reduce the transportation cost; 3, a super-large inspection shaft can be directly assembled in a pipeline channel and is convenient to construct, high in construction speed and low in construction cost; and 4, the connection mode of the wall board is reliable, simple and convenient; and the assembled inspection shaft chamber has high strength, tight joint, high durability and high bearing capacity, so that the service life of the inspection shaft chamber is prolonged.

Description

Technical field: [0001] The invention belongs to the category of reinforced concrete pipelines. It specifically relates to a prefabricated assembled reinforced concrete rectangular inspection well chamber. Background technique: [0002] In modern cities, various underground pipelines need to be equipped with inspection wells. In the past, inspection wells were all built with clay bricks, and the materials and construction techniques were relatively backward. Concretely there is following defect: 1, clay brick intensity is low, durability is poor, and use 7-8 year will take place clay brick crisp and rotten, thereby shortened the service life of manhole. 2. Make the sewage seep and pollute the groundwater. 3. Due to the need to burn clay bricks, a large amount of farmland is destroyed and the environment is polluted. 4. The mechanized construction level of the clay brick inspection well is low, the on-site operation time is long, the wet work workload is heavy, the mainten...

AI Technical Summary

Problems solved by technology

[0002] In modern cities, all kinds of underground pipelines need to be equipped with inspection wells. In the past, inspection wells were built with clay bricks, and the materials and construction technology were relatively backward.

Specifically, there are the following defects: 1. Clay bricks have low strength and poor durability. After 7-8 years of use, the clay bricks will become rotten, thereby shortening the service life of the inspection well.

2. Let the sewage seep, thereby polluting the groundwater

3. Due to the need to fire clay bricks, a large number of farmlands are destroyed and the environment is polluted

4. The mechanized construction level of the clay brick inspection well is low, the on-site operation time is long, the wet operation workload is heavy, and the maintenance time is long. After slotting, it cannot be backfilled for a long time, which is not conducive to shortening the construction period and quickly releasing the road.

The side length of this rectangular inspection well is about 5m. It is large in size and heavy in weight. The model is complicated in production, high in processing costs, difficult in production technology, high in production cost, inconvenient in handling and installation, and requires large-scale lifting equipment. high construction cost

The above reasons make the engineering cost of prefabricated reinforced concrete inspection wells much higher than that of brick inspection wells, which is the main obstacle that the current prefabricated reinforced concrete inspection wells cannot be popularized and applied as soon as possible.
