Press-in type sunk well reaction system

Abstract

The invention relates to a press-in type sunk well reaction system. A pressure-bearing 'bracket' and a wall of a sunk well are manufactured into a whole body by reinforced concrete pouring; a centre hole jack is arranged on the pressure-bearing 'bracket'; a bearing platform is fixedly connected with a reaction device; a reaction draw bar is connected between the reaction device and the centre hole jack; and the bearing platform is fixed on a reaction ground anchor. The press-in type sunk well reaction system is simple in structure and convenient to construct. Prerequisite conditions are provided for a novel sunk well construction method, namely a press-in type sunk well construction method. By using the press-in type sunk well reaction system, the whole stability and the whole safety of the sunk well are improved in sinking construction of the sunk well; the sinking construction of the sunk well can be effectively controlled; the sunk well sinks uniformly and stably; inclination and sudden sinking of the sunk well are avoided; the final sinking elevation of the sunk well can be controlled conveniently; the construction speed is increased; the work efficiency is improved; the construction period is greatly saved; the cost is saved; a phenomenon that peripheral soil masses are damaged during sinking of the sunk well is avoided; and the peripheral environment is effectively protected.

Description

technical field [0001] The invention relates to a caisson system for building construction, in particular to a press-in type caisson reaction force system. Background technique [0002] Due to its stable structure and low cost, caissons have been widely used in municipal and industrial fields such as water supply, drainage, and electric power. On the one hand, with the gradual improvement of caisson sinking construction technology, the underground space used by caissons is becoming more and more complex, and the field of unconventional crossing is becoming wider and wider. On the other hand, due to the excessive disturbance of the surrounding environment caused by caisson sinking construction, it has not been well solved, which limits its application in sensitive areas or complex soil external conditions. Coupled with the enhancement of people's awareness of environmental protection, the existing caisson sinking technology is becoming more and more difficult to meet the inc...
