Construction device of active assembling type open caisson and construction method using same

Abstract

The invention provides a construction device of an active assembling type open caisson and a construction method using same. The construction device comprises pouring piles, first steel pipes, second steel pipes, flange plates, upper pressing rods and oil pickaxe jacks, wherein a plurality of pouring piles are mounted around a mounting position of the active assembling type open caisson; first reinforcing steel bars are welded to the first steel pipes; two I-steels are overlapped and welded at the upper parts of the pouring piles to be used as the upper pressing rods, and the upper pressing rods are welded to the second steel pipes; the first steel pipes and the second steel pipes are connected through the corresponding flange plates; one or a plurality of oil pickaxe jacks are mounted below the upper pressing rods. The construction device has a plurality of advantages, such as that the overall stressing performance is outstanding, the structure stability is high, the construction area can be effectively reduced, the construction process is simple, the energy can be saved, the environment is protected, the construction safety coefficients are high, the construction time can be greatly decreased, the construction workload can be reduced, the applicable scope is wide, the stability in a special geological condition is outstanding, and the quality, the safety and the environment can be ensured.

Description

technical field [0001] The invention relates to a caisson system for building construction, in particular to an actively assembled caisson construction equipment and the caisson construction equipment using the construction method. Background technique [0002] With the development of sewage pipeline construction technology, mechanized construction has become the current development trend. The average speed of the conventional caisson construction method is 15 days / seat, therefore, the construction speed of the caisson will become the main problem restricting the construction of the project. The conventional main caisson construction methods mainly include: steel and large slab composite support construction, upside-down shaft wall anchor shotcrete construction, cast-in-place reinforced concrete caisson construction, etc. Choosing a reasonable construction method will have an important impact on the safety, quality and progress of sewage pipeline construction.

AI Technical Summary

Problems solved by technology

[0003] The traditional method adopts upside-down well wall bolting and spraying construction. When encountering silt and fine sand layers, the phenomenon of "quick sand" is easy to occur, which seriously affects the construction speed, and the soil grouting reinforcement increases the construction cost.

The conventional caisson construction method can effectively adapt to the silt and fine sand formation, but the construction period is relatively long, and it is difficult to guarantee the pipeline penetration period.
