Embodiment 1

[0030] see Figure 1-3 , air pressure caisson excavation device, it comprises caisson body 4, and the sealing partition 5 that is used for sealing the bottom of caisson body 4 is airtightly fixed on the lower inner wall of described caisson body 4, the bottom of described sealing partition 5 A plurality of cantilever excavators 6 are fixedly installed on the end surface, and the slag discharge channel 11 and the compressed air pipe 10 are communicated on the sealing partition 5, and the bottom end surface of the sealing partition 5 is installed with a The monitoring camera 13 and the pressure sensor 14 used to monitor the pressure of the sealed cavity at the bottom of the caisson body 4, the cantilever excavator 6, the camera 13 and the pressure sensor 14 communicate with the industrial system for controlling its work through the signal line 3 respectively. Computer 2 is connected. By adopting the excavation device with the above structure, the support condition of the caisso...

Embodiment 2

[0040] The using method of any one of the air pressure caisson excavation device may further comprise the steps:

[0041] Step 1: Install a sealing partition 5 at the bottom of the caisson body 4, and arrange a plurality of cantilever excavators 6 symmetrically and evenly along the center of the caisson body 4 under the sealing partition 5;

[0042] Step 2: install the compressed air pipe 10 and connect it with the air compressor 16, and use helium mixed gas to form a high-pressure sealing area between the sealing partition 5 and the excavation foundation 7;

[0043] Step 3: Control the corresponding cantilever excavator 6 through the industrial computer 2, and adjust the vertical angle and horizontal direction of the cantilever excavator 6 to carry out excavation and soil removal operations;

[0044] Step 4: At the same time as the soil extraction operation, the excavated soil in the high-pressure sealing area is extracted and discharged to the outside of the caisson body 4 b...

Abstract

The invention discloses a pneumatic caisson excavation device and a use method thereof. The pneumatic caisson excavation device comprises a caisson body, a sealing partition plate used for sealing thebottom of the caisson body is fixed to the inner wall of the lower part of the caisson body in an airtight mode, a plurality of cantilever excavators are fixedly mounted on the bottom end face of thesealing partition plate, the sealing partition plate communicates with a muck outward-discharge channel and a compressed air tube, a camera used for monitoring an excavation foundation and a pressuresensor used for monitoring the pressure of a sealed cavity in the bottom of the caisson body are mounted on the bottom end face of the sealing partition plate, and the cantilever excavators, the camera and the pressure sensor are connected with an industrial computer through signal lines correspondingly, wherein the industrial computer is used for controlling the cantilever excavators, the cameraand the pressure sensor to work. The operation process of soil taking excavation in the caisson construction process is intelligently controlled, the caisson support situation is monitored in real time, the states of the cantilever excavators are adjusted reasonably, the excavation soil-taking operation range is controlled, and the purpose of quick soil taking and efficient excavation through caissons is achieved.

Description

technical field [0001] The invention belongs to the technical field of excavation of large caissons, and relates to excavation of large air pressure caissons under complicated geological conditions, which is mainly used for excavation of caissons and soil extraction. Background technique [0002] With the development of my country's transportation infrastructure construction, large-scale caisson foundations have been widely used, and caisson excavation and sinking methods have also received more and more attention. During the excavation and sinking of ordinary caissons, due to the unknown elevation of the bottom of the pot and the difficulty of manual work, the current construction efficiency of caissons is low, and the method of earth extraction for ordinary caissons can no longer meet the needs of rapid earth extraction for large caissons. Real-time remote monitoring of caisson support, reasonable adjustment and allocation of bottom cantilever excavators, and enhancement o...
