Prefabricated sinking well and assembling method thereof

Abstract

The invention relates to the technical field of sinking wells, in particular to a prefabricated sinking well. The prefabricated sinking well comprises an inner sleeve and an outer sleeve. The outer sleeve is arranged on the outer portion of the inner sleeve in a sleeving manner. The inner sleeve and the outer sleeve are each composed of multiple arc plates. A groove and a protrusion are arranged at the two ends of each arc plate correspondingly. Prestress holes are reserved between the inner sleeve and the outer sleeve, and a prestress steel wire rope is mounted in each prestress hole. Compared with the prior art, the arc plates forming the inner sleeve and the outer sleeve in the prefabricated sinking well are prefabricated in a factory in advance, quite fast assembling can be achieved through the protrusions and the grooves on the two sides, and the inner sleeve and the outer sleeve between the upper layer and the lower layer are connected together through the prestress steel wire ropes; and in the prefabricated sinking well, the situation that the total construction period is delayed by steel bar framework welding and concrete strength waiting cannot happen, the influence of construction on road traffic and the lives of residents can be reduced to the largest extent, cleanliness and orderliness of the construction site can be kept, and extremely high application value is achieved.

Description

technical field [0001] The invention relates to the technical field of caissons, in particular to a prefabricated assembled caisson and an assembly method thereof. Background technique [0002] At present, the construction of road pipelines in most cities in China needs to excavate the road surface, which causes road congestion and has a great impact on urban traffic. In traditional caisson production, a reinforced concrete well body with openings is first made on the ground or in the foundation pit. After it reaches the specified strength, the soil is excavated in layers inside the well body and transported out. With the excavation and the lowering of the soil surface, the caisson body Under its own weight or with the assistance of other measures, it overcomes the frictional resistance between the soil walls and the counterforce of blades and feet, sinks continuously until the design elevation is in place, and then seals the back. The pouring of caissons on the constructio...

AI Technical Summary

Problems solved by technology

The pouring of caissons on the construction site takes up a large amount of road surface. This process has many construction techniques, high technical requirements, difficult quality control, and a long construction period, which brings dust, noise, etc., which not only pollutes the environment and creates noise, but also often easily causes The congestion of urban roads brings inconvenience to urban traffic and residents' lives

[0003] At present, domestic and foreign caisson manufacturing technologies mainly include on-site pouring and factory prefabrication. In engineering construction, caisson on-site pouring has many processes, high technical requirements, difficult quality control, and a long construction period, which brings dust, noise, etc. Not only pollute the environment, make noise, and bring inconvenience to urban traffic and residents' lives
