Fabricated tailing pond radiation well walling crib with fixing grooves and construction technology

Abstract

The invention discloses a fabricated tailing pond radiation well walling crib with fixing grooves and a construction technology. The walling crib comprises a plurality of arc-shaped prefabricated well walls, and the prefabricated well walls are spliced to form annular walling crib bodies. The walling crib bodies are spliced up and down to form a fabricated radiation well. The fixing grooves are integrally formed in the ends of the prefabricated well walls, fixing blocks are integrally formed at the other ends of the prefabricated well walls, and the fixing grooves and the fixing blocks between the left and right adjacent prefabricated well walls are mutually spliced to form the annular walling crib bodies. Preformed holes are formed in the prefabricated well walls in the longitudinal direction, fixing rods are arranged in the preformed holes, the bottoms of the fixing rods are arranged in the preformed holes of the prefabricated well wall on the lower portion of the upper prefabricated well wall and the lower prefabricated well wall, and the tops of the fixing rods are arranged in the preformed holes of the prefabricated well wall on the upper portion of the upper prefabricated well wall and the lower prefabricated well wall. The walling crib bodies are formed through left-right splicing, the upper walling crib and the lower walling crib are spliced to form the radiation well, installation is easy, construction is convenient, the installation efficiency can be improved, and construction risks are reduced.

Description

technical field [0001] The invention relates to the field of radiation well construction, in particular to an assembled tailings pond radiation well ring with a fixed groove and a construction process. Background technique [0002] The high infiltration line of tailings dam body is the biggest threat to the safety of tailings dam. At present, radiation well drainage technology is widely used to reduce the infiltration line of tailings dam. Cast-in-place reinforced concrete well circles are mostly used in the construction of radiation well caissons. When digging and sinking, the well ring is fabricated in sections, subsided in sections, and the fabrication and subsidence are carried out alternately. [0003] Problems in the cast-in-place reinforced concrete well circle: 1. The concrete well circle is cast in sections, and the next section must be made after the concrete reaches a certain strength, including formwork installation, steel bar production and installation, cast-in...

AI Technical Summary

Problems solved by technology

[0003] Problems in the cast-in-place reinforced concrete well circle: 1. The concrete well circle is cast in sections, and the next section must be made after the concrete reaches a certain strength, including formwork installation, steel bar production and installation, cast-in-place concrete, formwork removal, etc. The process takes a long time and the construction speed is slow; 2. Due to the slow progress of cast-in-place reinforced concrete during construction, there is a height difference between the height of the tailings inside the well circle of the radiation well and outside the well circle, and the well is dug below the groundwater level. With the peripheral groundwater backflowing into the well circle too quickly, the surrounding uneven backflow often leads to sideways deviation of the wellbore of the radiation well, and the axis of the wellbore is not easy to control, which affects the quality of the later installation of the radiant tube and the effect of seepage drainage, and seriously causes the displacement of the well circle, shearing Radiation pipes and diversion pipes lead to broken pipe accidents, and the construction quality is difficult to be guaranteed; 3. In-situ cast-in-place radiation wells need to install formwork, steel bars, and cast-in-situ concrete in the well, and work in a limited space. There are safety risks such as falling from high altitudes and falling objects from high altitudes in the operation, and the construction safety risk factor is relatively high; 4. On-site mixing of concrete will cause certain pollution to the construction site environment
