Integrated down-the-hole hammer with pouring function

Abstract

The invention provides an integrated down-the-hole hammer with a pouring function. The integrated down-the-hole hammer comprises a machine frame, a suspension device, a down-the-hole hammer body, a double-layer hollow drill rod, a power head, an air compressor, an air supply pipeline, a three-way pipe, a one-way valve, a ground pump, a sludge pumping device and an air converter. On the basis of absorbing the advantages of existing down-the-hole hammer equipment, by combining the long twist drill center pressure grouting pile forming technology and the reverse circulation technology principle, the integrated equipment integrating the reverse circulation technology and the grouting pile forming technology is developed, and the function that one hammer has two purposes is achieved.

Description

technical field [0001] The invention relates to the field of down-the-hole piling equipment, in particular to an integrated down-the-hole hammer with pouring function. Background technique [0002] Most of the existing down-the-hole hammers use compressed air and power heads as power to drive the down-the-hole hammer to achieve rotary impact and crush rock (soil) bodies, and use pipes or mud to protect the wall, and then use positive circulation to remove the cuttings at the bottom of the hole. transported to the ground. Although it solves the problems that the equipment is difficult to enter the rock and the hole is easy to collapse, there are still problems such as unclean slag removal at the bottom of the hole, heavy dust pollution, and the need for multiple equipment to cooperate with the construction during the construction operation. Therefore, there is an urgent need to use the principle of reverse circulation technology to develop a reverse circulation DTH hammer de...
