It is an important means to develop the vertical area of ​​underground space in the future. After the construction of undrained caisson, the groove at the bottom of the caisson will absorb sediment. When the concrete bottom is sealed, the integrity of the caisson and the bottom will be reduced, and even leakage from the bottom of the caisson will occur. Therefore, it is necessary to clean the bottom of the caisson. However, as the size and depth of the caisson increase, the workload of manual cleaning of scum is large and the risk factor is high. Therefore, it is urgent to develop a device that can automatically clean scum in the caisson to solve the above problems. Utility Model Content

[0030] The characteristics and functions of the present invention can be further understood through the following description.

[0031] As is known to all, the scum at the bottom wall and groove of the traditional undrained caisson cannot be removed. For ultra-large deep caisson structures, manual cleaning of scum is labor-intensive and dangerous. Therefore, in order to solve this problem, this embodiment provides a device that can automatically clean scum in caissons instead of people. Since vertical shaft driving equipment is usually used for large caisson excavation, this device is mainly used in conjunction with vertical shaft driving equipment.

[0032] The construction device of this embodiment mainly includes: a vertical telescopic rod 2 installed on a tunneling mechanism 1; a high-pressure rotating nozzle 3 installed at the protruding end of the vertical telescopic rod 2; and a water inlet pipe 4 connected to the vertical telescopic rod 2 at one end and to an external water source at the other end; a high-pressure water pump is installed between the water inlet pipe 4 and the water source.

[0033] The usage characteristics and construction technical scheme of the construction device of this embodiment are as follows:

[0034] like Figure 2 As shown, when the shaft excavation mechanism 1 excavates to the designed elevation, the vertical telescopic rod 2 is started, the high-pressure rotary nozzle 3 is turned on, and high-pressure spraying is performed to clean the bottom wall and groove of the caisson 6. The height of the high-pressure rotary nozzle 3 is adjusted by the vertical telescopic rod 2 to clean the bottom side wall and groove of the caisson 6 at different elevations. After cleaning, it can be lifted to the ground together with the shaft excavation mechanism 1.

[0035] In summary, the construction device of the utility model can realize the mechanization of the entire scum cleaning process at the bottom of the caisson, without the need for personnel to enter, thus ensuring the safety of personnel. When cleaning scum at the caisson, a high-pressure rotary nozzle is used instead of a traditional high-pressure water gun, which has a large sweeping area and high work efficiency. The high-pressure rotary nozzle is combined with a cleaning brush to clean the well wall and groove at the bottom of the caisson more thoroughly.
