Abstract

The invention belongs to the technical field of square pile hole digging, and provides an integrated square hole washing and fishing combined drill. The integrated square hole washing and fishing combined drill comprises a main shell, a transmission shaft, a square pile hole drill and a rotary drilling rig, wherein the transmission shaft is rotationally installed in the main shell and provided with a pin hole, and an external power machine is in driving connection with the transmission shaft through the pin hole; the square pile hole drill bit is installed on the main shell and is in driving connection with the transmission shaft, and the square pile hole drill bit comprises a transmission mechanism and a chain cutting mechanism; the transmission mechanism is installed on the main shell and located at the top of the main shell, and the chain cutting mechanism is installed on the peripheral surface of the main shell. The chain cutting mechanism is in driving connection with the transmission mechanism, and the transmission mechanism is in transmission connection with the transmission shaft. The rotary drilling rig is installed in the main shell and is in transmission connection withthe transmission shaft. The integrated square hole washing and fishing combined drill can tunnel a square pile hole, earth generated in the tunneling process of the square pile hole can be extracted,manual operation is replaced, the equipment cost is saved, two operation states are achieved, the cost is greatly saved, and the integrated square hole washing and fishing combined drill is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of square pile hole excavation, in particular to an integrated square hole washing and fishing compound drill. Background technique [0002] In existing engineering operations, since square hole piles are generally large in size and large in diameter, they are more suitable for carrying large vertical and lateral stresses, and are widely used in various slope support, anti-slide pile foundation support, large Bearing foundation, so there is a great demand for square hole piles. [0003] During the excavation of the square pile hole, a large amount of accumulated soil is produced under the square pile hole, and the accumulated soil needs to be extracted and transported manually, which greatly increases the working time, and also increases the labor cost and equipment investment. cost. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides an integrated sq...
