Abstract

The invention belongs to the technical field of well digging and piling and particularly relates to well drilling equipment, in particular to a water hammer type well drill. The invention aims at providing a well drill which is low in noise, obvious in effect, high in energy using ratio and capable of drilling an inclined well when used in an area with soft soil and an uncomplicated geological condition. Water is drawn from a drain pipeline through a water pump and is supplied to a water hammer pipeline. When the water in the water hammer pipeline arrives at a certain speed, the valve is closed, once water hammer impact is produced, momentum of the water flow is transformed into the momentum of the whole well drill, and a soil layer is hit once. Then, a valve plate is opened under the action of a valve plate starter, the water flow flows again, enters into the drain pipeline after being shunted through a shunting cavity and is sent to a water outlet of the water pump, and once circulation is finished. A direction controller controls the drilling direction of the well drill. The two-way oil-pressure adjustment device is rigid in noise control and conducts drilling operation in the area with the soft soil and the uncomplicated geological condition.

Description

Technical field:

[0001] The invention belongs to the technical field of well drilling and piling, and in particular relates to a drilling equipment, specifically, a water hammer drilling machine. technical background:

[0002] In current engineering practice, commonly used drilling rigs can basically be divided into percussion drilling rigs and hydraulic drilling rigs. Percussive drilling rigs have low energy efficiency and high noise. During urban construction, they have a relatively large impact on surrounding residents and are not suitable for use in areas with relatively high noise requirements. Hydraulic drilling rigs have low noise, but high energy consumption, complex structure, high production and construction costs. When used in areas with soft soil and uncomplicated geological conditions, energy will be wasted and construction costs will be increased. When the two kinds of drilling machines are used in inclined wells, the effect is not obvious. Invention content...

Examples

Embodiment Construction

[0030] Such as figure 1 As shown, 1 numerical control box is on the ground, connect the drilling machine with 2 cables, increase the power supply to the drilling machine, and manually control the movement of the 6-direction controller, control the operation and speed of the 7-water pump, and control the start-up of the 10-valve board speed of the machine.

[0031] Such as figure 2 As shown, the valve plate 16 is on the base of the valve 17, and the water flow channel in the water hammer pipeline of the 13 can be closed or opened by moving the valve plate 16 up and down. The 16 valve plate is a disk, and its surface is a convex cone; the 17 valve base is a ring, and its surface is a concave cone, when the 16 valve plate and the 17 valve base are closed, there is no gap between the two, and the 17 valve base has Eight legs, distributed in a regular octagon, are welded on concentric circles of 20 drill bits.

[0032] Such as image 3 As shown, the shell of 11 is connected w...
