Description

It is lower to drilling with boring plugging type slag-draining device and method
Technical field
The invention belongs to lane (tunnel) road support technology fields, and in particular to drilling with brill plugging type slag-draining device under a kind of And method.
Background technique
Drilling is the important behaviour form of coal petrography cutting in coal and rock, and according to requirement of engineering, drilling depth, direction can not yet Together.In the construction such as mine support, rock blasting, generally require to creep into several meters to tens meters depth and towards drilling not etc., The discharge that drilling at this time generates landwaste is then the key factor for influencing drilling efficiency.Deslagging during domestic and international drilling construction at present Method mainly has: cutting pick-up with high pressure water, high-pressure blast deslagging and mechanical spiral deslagging.But the above deslagging mode is primarily adapted for use in large hole Drilling of diameter such as geotechnical boring, gas extraction hole etc..Diameter downward for direction is smaller and the biggish drilling construction of depth, high Water is pressed to influence vulnerable to drilling depth, as drilling depth increases, water conservancy gradient is gradually decreased, it is extremely difficult to ideal deslagging pressure, And the influence of high-pressure blast and mechanical spiral deslagging mode vulnerable to hole wall integrity, in collapse hole area, deslagging power drops suddenly, easily causes Plug-hole, armful brill, bit freezing etc., stablize effective deslagging power to not can guarantee, in addition, both deslagging modes also will cause sky Gas seriously pollutes.Therefore, a kind of method that can guarantee effective, stable deslagging power is found, for improving small-bore, larger depth The hole quality and deslagging effect for spending drilling, reduce air pollution, are of great significance.
Summary of the invention
The present invention provides that a kind of to be able to maintain constant negative pressure deslagging empty to solve shortcoming in the prior art Between, to formed stablize effective deslagging power, improve Completion of Drilling Hole quality and deslagging effect it is lower to drilling with boring plugging type Slag-draining device and method.
In order to solve the above technical problems, the present invention adopts the following technical scheme: it is lower to drilling with bore plugging type slag-draining device, Including vertically arranged upper hollow connecting rod, under hollow connecting rod, sealing bearing, block cushion rubber, upper deslagging conduit and lower row Slag conduit;
