Abstract
The invention discloses an embedding construction method of an orifice pipe. The method comprises the following steps: a. drilling a horizontal or upward orifice pipe section borehole according to the outer diameter of the orifice pipe; b. drilling a small-caliber borehole at a certain angel at the open side of the orifice pipe section borehole by utilizing a handheld pneumatic rock drill on the pregrouting working surface, communicating the small-caliber borehole with the orifice pipe section borehole and installing a grouting mouth; c. simply and easily fixing one end of a small-diameter plastic flexible pipe with the length larger than the length of the orifice pipe in the inner port of the orifice pipe; enabling the other end to be exposed out of the outer exposed end of the orifice pipe; transferring the orifice pipe into the orifice pipe section borehole to be fixed in the definite position; maintaining the plastic flexible pipe to be positioned in the highest point at the bottom of the borehole at one end in the borehole; d. filling waste cotton yarn in the annular gap between the outer exposed end of the orifice pipe and the wall of the borehole and the inner cavity of the orifice pipe; and e. carrying out the mud jacking solidification of the orifice pipe. The technical scheme in the invention can effectively solve the problems of difficult embedding construction of pregrouting and water-plugging the upward or horizontal borehole orifice on the working surface of a roadway or a tunnel, thereby conveniently, rapidly and effectively carrying out the embedding construction of the borehole.
Description
Technical field
The present invention relates to a kind of embedding construction method of orifice pipe, be applicable to underground mine tunnel and subterranean tunnel pre grouting from the working face water blockoff and look up or horizontal drilling orifice tube burial and construction.
Background technology
In mine or construction of tunnel pre grouting from the working face plug water construction, orifice tube is as the crucial equipment of slip casting operation, its security reliability of burying underground is directly connected to boring and discloses the aquifer when water burst occurring, can orifice tube itself close orifice valves and satisfy behind the door the basic demand that seepage does not occur proposing drilling tool, the more important thing is that simultaneously can when slip casting operation orifice tube satisfy withstand voltage impervious needs under at least 2 ~ 4 times of hydrostatic pressures even the higher grouting pressure.The angle of inlet well is different because of the slip casting work plane.In the pre-slip casting of Shaft Stopes, hole as lower to upright opening with overlook inclined hole.And in the pre-slip casting in gallery, inclined gallery or tunnel front, there is again lateral aperture in the existing low-angle hole of overlooking of holing and looks up the hole.For burying underground of pre-inlet well orifice tube, its program is that the first Drilling degree of depth generally surpasses the orifice tube of burying underground and enters boring about hole depth 0.1m.Then bore diameter adopts clear water that rock dust in the hole is rinsed well to be advisable than the large 2 ~ 4mm of orifice tube external diameter.After finishing above-mentioned work, carry out orifice tube and bury underground.On method for embedding, for lower to upright opening with overlook inclined hole, common way is in advance to the interior cement injection mortar of boring or cement paste, again orifice tube is sent into also to locate in the hole and fixed, after cement mortar or cement paste maintenance certain hour reach certain intensity, adopt rig that the slurries calculus body in the orifice tube is bored except and use grouting pump to adopt 1.2 times of design final grouting pressures to carry out withstand voltage impermeability test, could formal boring disclose the aquifer after qualified.And for level and look up orifice tube, can not adopt in the hole cement injection mortar or cement paste method pre-buried.Existing document does not have ripe technology report yet.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of embedding construction method of orifice pipe, can be convenient, fast, effectively carry out that the pre-grouting for water blocking in tunnel or tunnel front is looked up or horizontal drilling orifice tube burial and construction.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of embedding construction method of orifice pipe may further comprise the steps: a, according to the external diameter Drilling level of orifice tube or look up aperture pipeline section boring; B, at pre-slip casting work plane hand-held air rock drill, at the side direction of the perforate of aperture pipeline section boring at a certain angle Drilling small diameter hole and aperture pipeline section boring perforation and installation grouting nozzle; C, with a length greater than the simple and easy orifice tube inner port that is fixed in of minor diameter plastic flexible pipe one end of orifice tube length, the other end exposes to the exposed junction of orifice tube; Orifice tube is sent in the boring of aperture pipeline section to determining that the position fixes, and an end that keeps plastic flexible pipe to be positioned at boring is in peak at the bottom of the drilling hole; D, with the inner chamber of the exposed junction of orifice tube and the annular space between the drill hole wall and orifice tube with the filling of waste cotton yarn; E, carry out the consolidation grouting of orifice tube.
Drilling level or when looking up the boring of aperture pipeline section, aperture pipeline section bore diameter are with than the large 2 ~ 4mm of orifice tube external diameter, and aperture pipeline section drilling depth generally surpasses the orifice tube of burying underground and enters about hole depth 0.1m.
When carrying out the orifice tube consolidation grouting, adopt grouting pump to be pressed in the annular space between orifice tube and drill hole wall by grouting nozzle with low discharge (5 liters ~ 10 liters of per minutes) in the dense fast setting cement slurry for preparing; Cotton yarn the bleeding increase occurs and reaches when stablizing within occurring the filling cotton yarn between cement paste outflow, orifice tube exposed junction and drill hole wall in the stack and managing, and mud jacking can finish.The water/binder ratio (quality) of described dense fast setting cement slurry is preferably 0.5:1 to 1:1.
Adopt this technical scheme, can solve effectively that the pre-grouting for water blocking in tunnel or tunnel front is looked up or a difficult problem that horizontal drilling orifice tube burial and construction exists, thus convenient, fast, carry out the orifice tube burial and construction efficiently.
The specific embodiment
The below elaborates to the specific embodiment of the present invention.
A kind of embedding construction method of orifice pipe of the present invention may further comprise the steps: a, according to the external diameter Drilling level of orifice tube or look up aperture pipeline section boring; B, at pre-slip casting work plane hand-held air rock drill, at the side direction of the perforate of aperture pipeline section boring at a certain angle Drilling small diameter hole and aperture pipeline section boring perforation and installation grouting nozzle; C, with a length greater than the simple and easy orifice tube inner port that is fixed in of minor diameter plastic flexible pipe one end of orifice tube length, the other end exposes to the exposed junction of orifice tube; Orifice tube is sent in the boring of aperture pipeline section to determining that the position fixes, and an end that keeps plastic flexible pipe to be positioned at boring is in peak at the bottom of the drilling hole; D, with the inner chamber of the exposed junction of orifice tube and the annular space between the drill hole wall and orifice tube with the filling of waste cotton yarn; E, carry out the consolidation grouting of orifice tube.
