Abstract

The invention relates to the technical field of down-the-hole rock breaking construction structures, and discloses a pipe-following dual-power rock breaking construction structure with an all casing and a down-the-hole hammer. The pipe-following dual-power rock breaking construction structure comprises a drilling machine, the all casing, a pipe shoe and the down-the-hole hammer, the all casing and the pipe shoe are arranged in a connected mode, the lower portion of the down-the-hole hammer is arranged on the all casing in a penetrating mode and extends to the interior of the pipe shoe, the lower portion of the down-the-hole hammer and the pipe shoe are fixedly arranged in a meshing mode or movably arranged in a separated mode, and the upper portion of the down-the-hole hammer and the drilling machine are arranged in a connected mode, the drilling machine comprises an inner power device and an outer power device, the outer power device is used for providing pressurizing force and rotation power for the pipe shoe, the inner power device is used for providing reciprocating impact force for the down-the-hole hammer, a plurality of drilling teeth are arranged on the lower portion of the pipe shoe and used for breaking a rock stratum to form a rock core, the down-the-hole hammer is used for breaking the rock core, the down-the-hole hammer drills to drive the pipe shoe to be arranged in a synchronous drilling mode, and a height difference exists between the drilling teeth and the down-the-hole hammer. The inner power device and the outer power device are adopted to cooperate, and therefore drilling construction and chiseling construction are combined, rock stratum breaking is facilitated, and the construction effect is greatly improved.

Description

technical field [0001] The patent of the present invention relates to the technical field of the rock-breaking construction structure of the down-the-hole hammer, specifically, it relates to the dual-power rock-breaking construction structure of the full casing and the down-the-hole hammer and the tube. Background technique [0002] The underground diaphragm wall has been more and more used in the construction of urban underground space because of its good supporting and water-stopping effects. [0003] According to the ground conditions of the site, the commonly used construction equipment for underground diaphragm walls includes hydraulic grab slotting machines, punching pile machines, rotary pile machines, and double-wheel milling. In hard rock formations, the latter three machines are generally used alone or in combination to complete the construction Groove after drilling and repairing. [0004] In the prior art, the above-mentioned construction equipment is used for c...
