Problems solved by technology

[0003] At present, there are two main ways to clean the slots in the industry at home and abroad: one is to use a double-wheel milling machine to clean the slot and change the slurry; the other is to use the gas lift reverse circulation process to change the slurry; the use of the double-wheel milling machine The cost is high, and it is not economical to use the slag removal and pulp change in the slot, and the weight of the double-wheel slot milling machine is heavy. There is a risk of hole collapse when cleaning the slag and changing the pulp next to the dug slot for a long time; the gas lift reverse circulation process requires With the assistance of crawler cranes and manual on-site pipe connection, the slurry change time is as long as 8-10 hours, and the impact of the airflow is unstable, which may easily cause impact on the wall of the dug slot hole and cause the risk of hole collapse

Embodiment 1

[0026] Such as figure 1 As shown, the present invention provides a kind of slotted sediment cleaning method, comprises the following steps:

[0027] Lower the tank cleaning device into the sediment in the slot hole to be cleaned. The tank cleaning device includes a frame body and a stirring device, a slag discharge pump and a mud motor arranged on the frame body; the frame body of the tank cleaning device is also provided with an expansion device for Adjust the thickness of the tank cleaning device according to the thickness of the slot hole to be cleaned; the frame body is also provided with a wall brushing device for brushing the tank wall; the stirring device provided on the tank cleaning device includes stirring wheels symmetrically arranged on the tank cleaning device The rotation direction of the stirring wheel is opposite when it works, which is used to increase the stability of the tank cleaning device. The speed of the stirring wheel is determined by the depth. The gr...

Embodiment 2

[0033] Such as figure 2 As shown, the present invention also provides a slot cleaning machine, comprising a slot cleaning machine body 1, a slag discharge mechanism 2, a mud mechanism 3 and a slot cleaning device 4, and the slot cleaning machine adopts the slot hole sediment described in embodiment 1 The cleaning method is to clean the slotted sediment.

[0034] According to the order of first two sides and then the middle, the slot cleaning machine is divided into three knives according to the slot cleaning method described in embodiment 1, and the slots to be cleaned are cleaned of sediment, and the time of each knives is determined by the concentration of sediment.

[0035] After the slot hole sediment has been cleaned, clear water can be used to clean the slot cleaning device 4 in the slot cleaning machine to prevent the mud from solidifying and clogging.

Abstract

The invention discloses a groove hole sediment cleaning method and a groove cleaning machine. The groove hole sediment cleaning method comprises the following steps that a groove cleaning device is lowered to enter groove hole sediment to be cleaned; new mud is injected into sediment through a groove cleaning device; the tank cleaning device is used for stirring the injected new slurry and sediment; the mixture of the new slurry and the sediment is discharged out of the groove hole through the groove cleaning device; and the groove cleaning device continues to be lowered, and the operation is repeated till the groove cleaning device reaches the target depth. Through the groove cleaning device, slag discharging and slurry changing integrated operation is achieved, the construction efficiency is improved, and the construction safety is improved.

Description

technical field [0001] The invention relates to a method for cleaning slot sediment and a slot cleaning machine, which belong to the technical field of engineering machinery. Background technique [0002] With the rapid development of domestic underground space engineering, the construction technology of underground diaphragm wall has been widely used. In the construction of underground diaphragm wall, the construction of slot holes is the key step. In order to ensure the quality of the wall of the underground diaphragm wall, it is necessary to Clean up the sediment at the bottom of the slot and replace the mud in the slot. [0003] At present, there are two main ways to clean the slots in the industry at home and abroad: one is to use a double-wheel milling machine to clean the slot and change the slurry; the other is to use the gas lift reverse circulation process to change the slurry; the use of the double-wheel milling The cost is high, and it is not economical to clean...
