Abstract
The invention relates to a quick plugging and draining device and method of a pressure water outlet for tunnel engineering, solving the problems that time and labor are wasted and normal construction is influenced because the water or the cement is plugged after being jet in the traditional tunnel engineering drilling. The device comprises a steel pipe, wherein one end of the steel pipe extends to a drill hole, and the outer cylindrical surface of the steel pipe is provided with a thread, while the other end of the steel pipe is provided with a control valve; one end of the control valve is connected with a draining pipe; a water stopping piece is sleeved on the steel pipe and consists of two metal pieces and a rubber piece clamped between the two metal pieces; and two sides of the water stopping piece are respectively provided with a nut screwed on the steel pipe. The invention has the advantage of reasonable and reliable structural design and quickly and efficiently realizes the plugging to the drill hole; meanwhile, jet objects such as the water or slurry, and the like are drained to a draining system or a concrete transport cart to guarantee the safe operation of construction stuff; and the invention is suitable for the quick plugging and control of leveling advanced drilling confined water or slurry of tunnel construction.
Description
Technical field
The present invention relates to the quick blocking drainage technology of pressure weep hole, be specially a kind of pressure weep hole quick blocking drainage system and method that is used for construction of tunnel.
Background technology
Increasing along with construction of tunnel, tunnel gushing water, prominent mud accident happen occasionally, even cause serious casualty accident.For preventing that gushing water, prominent shale ground disaster from taking place; Need to verify geological condition in development end (face) horizontal protruded drill hole; But in case after being drilled into artesian aquifer (or mud layer) and extracting drilling rod; Water or mud are spurting under pressure, have a strong impact on normal construction, must water that eject or mud drainage in an organized way delivered to the construction drainage system or transport spoil disposal area to concrete transport vehicle.
Ran into this situation in the past, and adopted the ditching on ground temporarily, pile up methods such as sand hill etc. cuts, blocks up, draws, time-consuming uneconomical, and influence normal construction.
Summary of the invention
The present invention sprays the problem that the back shutoff exists wastes time and energy and influence normal construction in order to solve existing tunnel engineering the drilling generation water or mud, and a kind of pressure weep hole quick blocking drainage system and method are provided.
The present invention adopts following technical scheme to realize: pressure weep hole quick blocking drainage system; Comprise that an end stretches into boring and external cylindrical surface is provided with the steel pipe of screw thread; The other end of steel pipe is provided with by-pass valve control, and an end of by-pass valve control is connected with drainage tube, is with sealing part on the steel pipe; Sealing part is made up of two sheet metals and the sheet rubber that is clipped between the two metal sheets, and the both sides of sealing part are equipped with the nut that is screwed on the steel pipe.After finding to have artesian water or mud to discharge behind the horizontal drilling to take out drill bit, the nut of sealing part and its both sides is installed in steel pipe one end, and tightens the sealing part nut outside, the flow of steel pipe outer end installation and control valve control water or mud after this end stretched into boring; The by-pass valve control other end is installed drainage tube water or mud is rationally discharged, and has overcome existing tunnel engineering the drilling generation water or mud and has sprayed the problem that the back shutoff exists wastes time and energy and influence normal construction.
The sealing part outside is provided with rapid hardening shutoff material, after sealing part is fixing, in the boring in the sealing part outside, adds rapid hardening shutoff material, guarantees the durability of shutoff.
The quantity of sealing part is several, and is equipped with nut and rapid hardening shutoff material between adjacent two sealing parts; With another sealing part be positioned at this sealing part nut outside and be inserted in steel pipe and rotate to the boring end, adding rapid hardening shutoff material continued swivel nut is to tightening in boring; Last repeatedly step to rapid hardening shutoff material level has further improved plugging effect in the boring port.
The outward flange of sheet metal slopes inwardly, and under the effect of sheet metal water or mud pressure in boring, to outside power of sheet metal, has further improved the sealing performance between sheet metal and sheet rubber and the boring inwall.Because increased after the sheet deformation and hole wall between frictional force, improved the fastness of plugging device in the hole.
Pressure weep hole quick blocking drainage method, step is following: find to have artesian water or mud to discharge behind a, the horizontal drilling; B, take out drill bit after, the nut of sealing part and its both sides is installed in steel pipe one end, and tightens the sealing part nut outside after this end stretched into boring; C, then with another sealing part be positioned at this sealing part nut outside and be inserted in steel pipe and rotate to the boring end, adding rapid hardening shutoff material continued swivel nut is to tightening in boring; D, repeatedly last step to rapid hardening shutoff material level in boring during port in the steel pipe outer end flow of installation and control valve control water or mud; E, the by-pass valve control other end are installed drainage tube water or mud are rationally discharged.
Reasonable in design of the present invention is reliable; Overcome existing tunnel engineering the drilling generation water or mud and sprayed the problem that the back shutoff exists wastes time and energy and influence normal construction; Realize shutoff quickly and efficiently to boring; Simultaneously with spray drainage to drainage system or concrete delivery trucks such as water or mud, ensure constructor's normal operation, be applicable to that the level of constructing tunnel drills the quick blocking and the control of artesian water or mud in advance; Also be applicable to simultaneously that hydraulic tunnel, underground mineral exploitation run into occasions such as artesian aquifer quick blocking and controlled discharge; Also can be used for the occasions of speedily carrying out rescue work such as other gushing waters, prominent mud, prominent gas.
