Description

Technical Field

[0001] This utility model relates to the field of CFG pile construction technology, specifically to a CFG pile construction mud removal device. Background Technology

[0002] CFG piles are cement-fly ash-gravel piles, made by mixing gravel, stone chips, sand, fly ash, cement, and water in a certain proportion, then drilling holes using various pile-forming machines, and pumping the mixture into the holes to create variable strength piles with a certain strength. In CFG pile construction, long spiral drilling machines are typically used. For example, in a drilling device for CFG pile construction shown in Chinese Patent Publication No. CN217380554U, the material discharge mechanism includes a material discharge motor, a material discharge auger, and a central fixed shaft. The material discharge motor is mounted on a lifting frame, and the lower end of the motor's power shaft is connected to the material discharge auger. A central fixed shaft is installed inside the material discharge auger, and the upper end of the central fixed shaft is connected to the lifting frame. The support mechanism includes an outer cylinder and an inner cylinder. The inner cylinder is fitted outside the material discharge auger, the small tunnel boring machine, and the locking mechanism, while the outer cylinder is fitted outside the inner cylinder.

[0003] However, when drilling using a discharge auger, as the auger rod of the long auger drilling machine is lifted upwards after drilling downwards, the soil attached to the auger rod's auger groove will be carried into the air and adhere to the inner cylinder. This not only easily causes the soil to clog the inner cylinder, but also the soil that is carried out can fall from the air and easily injure construction workers. Utility Model Content

[0004] Therefore, this utility model provides a mud removal device for CFG pile construction to solve the problem in the prior art that, during the upward lifting process after the auger rod of the long auger drilling machine has finished drilling downwards, the mud attached to the auger rod in the auger rod will be carried into the air and attached to the inner cylinder, which not only easily causes the mud to block the inner cylinder, but also easily injures the construction personnel when the mud carried out from the air falls.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mud removal device for CFG pile construction includes a fixed plate fixedly mounted on a vehicle. A drilling device for drilling holes in the foundation is provided on the right side of the fixed plate.
