Method for efficiently breaking open caisson sinking obstacles

Abstract

The invention relates to a method for efficiently breaking open caisson sinking obstacles. The method comprises the following steps that 1, a breaking device is installed on a telescopic arm excavator; 2, the foundation is treated so that a telescopic arm can over the caisson wall to clear the obstacles under the open caisson; 3, when breaking the obstacles, the telescopic arm excavator has to betightly attached to the inner wall of the open caisson, and the water level in the caisson have to be maintained during the breaking process to prevent the open caisson from sinking suddenly; and 4, the breaking device is used to remove debris of under-caisson obstacles out of the cutting edge to the inside of the caisson, an ordinary digging bucket is replaced, the debris are moved out of the caisson, and water pumping and sinking are carried out. The method for efficiently breaking the open caisson sinking obstacles has a remarkable effect on solving the problems of difficult sinking of theopen caisson, inclination in open caisson sinking and the like, the efficiency of breaking the obstacles by using the telescopic arm excavator is higher compared with a traditional method, and the pertinence is higher; and after a section of breaking work is completed, the mechanical displacement of the next section of work is faster, more flexible and convenient. Moreover, compared with the traditional method, using a cantilever excavator to take soil under the cutting edge is more convenient and faster.

Description

technical field [0001] The invention relates to a method for removing obstacles in the sinking of a caisson, in particular to a deviation correcting construction method suitable for when the sinking of the caisson is hindered by obstacles. Background technique [0002] When the caisson sinks, due to poor geological conditions and underground hard obstacles, there are obstacles at the foot of the caisson blade, which leads to the obstruction of the sinking, causing problems such as too slow sinking of the caisson, tilting of the caisson, etc. Detrimental effect on heavy weight. And if the correction speed is too slow and the correction effect is poor, it will cause more serious quality and safety problems. Therefore, a set of efficient and fast equipment is needed to correct the deviation of caissons. Contents of the invention [0003] The invention aims to solve the obstacle removal problem when the caisson sinks, and provides a method for efficiently removing undergroun...
