Embodiment Construction

[0021] The detailed structure, application principle, function and effect of the present invention are illustrated through the following embodiments.

[0022] The karst landform water mill drilling construction technology of the present invention comprises the following steps:

[0023] a) On the ground surface to be constructed, mark out the outer circumference of the target hole according to the position and size of the target hole, and mark two mutually perpendicular diameter lines with the center of the target hole as the intersection point;

[0024] b) Carry out core drilling operations along the outer circumference of the above target hole: the drill tube is placed on a guide rail vertical to the surface, the central axis of the drill tube intersects the outer circumference of the target hole perpendicularly, the upper end of the drill tube is connected to the motor, and the water outlet of the water pipe is connected to the drill During operation, the motor drives the dr...

Abstract

The karst landform water mill drilling construction technology of the present invention relates to the technical field of construction engineering, and aims to solve the difficulties in breaking hard rocks, slow construction progress, large noise, and poor foundation hole forming effect in the traditional foundation hole forming construction technology with hard foundation rocks. technical problem. The karst geomorphic water mill drilling construction technology of the present invention includes the following steps: a) On the ground surface to be constructed, mark out the outer circumference of the target hole and two mutually perpendicular diameter lines according to the position and size of the target hole; Carry out core drilling on the outer circumference of the hole; c) Repeat step b until all core drilling operations along the outer circumference of the target hole are completed; d) Adopt the core drilling operation method of steps b to c, and follow the two diameters described in step a The core drilling operation is carried out on the line, and the central axis of the drill barrel intersects the diameter line perpendicularly during the operation; e) Break and remove the stones in the target hole.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a water mill drilling construction technology applied to karst landforms with hard foundation rocks. Background technique [0002] In karst landform areas, the foundation rock is hard, and there are usually two methods for excavating foundation holes in such areas. One is to use pneumatic picks to excavate foundation holes, and the progress of foundation hole excavation is slow, and it is more difficult to drill holes at large depths; The blasting operation has great damage to the hole wall, and is not suitable for the effect of forming holes in multiple places in a small area, and the influence between adjacent foundation holes is relatively large. [0003] Taking the excavation of foundation holes with pneumatic picks as an example, the construction principle is that the diesel air compressor is the power source of the pneumatic pick, and the drill bit of the p...
