Well piece, prefabricated assembled caisson and caisson construction method

Abstract

The invention provides a prefabricated assembled caisson. The prefabricated assembled caisson comprises a ring well body and a plurality of tubing bolts, the ring well body comprises at least two arc-shaped well pieces, first arc round holes are formed in the two opposite sides of the well pieces, the first arc round holes in the two adjacent well pieces in the circumference direction communicatewith each other, and the tubing bolts penetrate through the first arc round holes to fix and connect the two adjacent well pieces. When the prefabricated assembled caisson is transported, the tubing bolts can be loosened in a screwed mode to remove the two adjacent well pieces, the transporting space occupied by the prefabricated assembled caisson is reduced so as to transport more prefabricated assembled caissons to reduce the transporting cost; when the transported well pieces reach to a designated location, the two adjacent well pieces can be quickly assembled and connected through the tubing bolts, and then the ring well body is installed in the caisson construction place and sunken; and compared with the site pouring concrete, the construction is simple and convenient, the construction efficiency is improved, in addition, the invention further provides a caisson construction method.

Description

technical field [0001] The invention relates to the field of caisson mechanisms, in particular to a well slice, a prefabricated assembled caisson and a construction method for the caisson. Background technique [0002] The existing pouring caisson structure has problems such as large construction area, long construction period, construction operation is greatly affected by weather changes, and high engineering cost. However, the prefabricated caisson has a shorter construction period than the traditional caisson construction method and reduces wet work. , The working area of ​​the on-site construction is small, the size prefabrication precision is high, the construction quality can be guaranteed, the economy of scale is used, the project cost is low, the construction of the prefabricated caisson is easy to realize and the modern civilized construction of the construction site is clean and orderly. [0003] The current prefabricated caisson needs to pour concrete at the joint...

Problems solved by technology

[0002] The existing pouring caisson structure has problems such as large construction area, long construction period, construction operation is greatly affected by weather changes, and high engineering cost. However, the prefabricated caisson has a shorter construction period than the traditional caisson construction method and reduces wet work. , the operation area of ​​on-site construction is small, the size prefabrication precision is high, the construction quality can be guaranteed, the use of economies of scale, the project cost is low, the prefabricated caisson construction is easy to realize and keep the construction site clean and orderly modern civilized construction

[0003] The current prefabricated caisson needs to pour concrete at the joints between the well slices to fasten the well slices together. There are still problems such as long construction time and low construction efficiency.
