Abstract
The utility model provides a drilling hole stepped advance type block up water grouting device, which mainly comprises a grouting pump, a grout inlet pipe (1), an orifice tube (8), a grouting tee and an exhausting and residue extraction means (6) and a water inrush resisting device (5), wherein one end of the orifice tube (8) is positioned in a drilling hole and fixed on the hole wall, the other end of the orifice tube (8) is positioned outside a drilling hole (11) and connected with the exhausting and residue extraction means (6) by a joint (7), the exhausting and residue extraction means (6) is connected with the water inrush resisting device (5) by a flange, the other end of the water bursting resisting device (5) is connected with the grouting tee with a grout inlet valve (2) and a pressure relief valve (3) by a flange, and the grouting tee is communicated with the grouting pump by the grout inlet pipe (1). The drilling hole stepped advance type block up water grouting device is suitable for high hydraulic pressure water-rich running sand or soft broken water shutoff, drills and grouts repeatedly, the pressure can be controlled, the grout disperses uniformly and the grouting effect is good, which can ensure excavation safety, increase construction speed and has large popularization and application value.
Description
Technical field
The utility model belongs to the leading water blockoff and the reinforcing technique of tunnel and the high hydraulic pressure of underground construction, rich water weak broken wall rock, mainly proposes a kind of boring segmentation protrusive grouting for water blocking device.
Background technology
In high hydraulic pressure, rich current layer of sand or soft stratum, carry out tunnel and underground engineering construction, the problem of easy appearance is the country rock large deformation and caves in and excavate face water burst, prominent mud, jeopardize personnel, device security, cause casualty accident, when serious, may cause that the face of land caves in, drawdown, vegetation is withered, influences resident's normal life, and ground environment is damaged.In order to guarantee construction safety, stratum consolidation and shutoff method commonly used both at home and abroad at present are slip casting method, slip casting method is exactly by certain pressure a certain amount of gelling material to be injected the rock stratum or the soil body, make that it flows in formation fractures or soil body space, diffusion, filling, fixed, be formed with the adhesive bond of certain intensity and low permeability, strengthening stratum, shutoff underground water, thereby improve the self-stabilization time of country rock, guarantee excavation safety.According to the difference of slip casting principle, technology, equipment, grouting method relatively more commonly used both at home and abroad at present is the disposable slip casting in full hole.This method slurries often form passage along some weak part on the drill hole wall, spreads far, and other position slurries diffusions seldom or do not spread, and causes the uniformity of stratum consolidation relatively poor.This in addition method relatively is fit to shallow bore hole slip casting, when carrying out deep hole grouting, if drill hole wall caves in or grouting tube on slurry outlet stopped up by silt, may cause at the bottom of the hole and middle some position is difficult to into slurry, influence slip casting effect.
Summary of the invention
The purpose of this utility model is to propose a kind of boring segmentation protrusive grouting for water blocking device, and the segmented slip casting that is used to hole makes the slurries diffusion ratio more even, obtains reasonable slip casting effect.
Technical pattern of the present utility model is: it mainly comprises grouting pump, inlet pipe and orifice tube, slip casting threeway and deslagging exhaust plant, anti-gushing water device; Orifice tube one end is positioned at drilling orifice and is fixed on the hole wall, its other end is positioned at outside the boring and by joint and connects with the deslagging exhaust plant, the deslagging exhaust plant connects with anti-gushing water device by flange, the anti-gushing water device other end is connected with the slip casting threeway that has slurry-inlet valve and relief valve by flange, and the slip casting threeway is communicated with grouting pump by inlet pipe.
The utility model device slip casting course of work: get out shallow bore hole (about 1.8m) with rig earlier, withdraw from drilling rod, orifice tube one end is headed in the boring with rig and be fixed on the port wall with the anchoring agent, orifice tube is positioned at boring outer an end and deslagging exhaust plant, anti-gushing water device connects, by the deslagging exhaust plant, anti-gushing water device begins to continue boring after design hole depth, withdraw from drilling rod, anti-gushing water device is by its other end flange and have slurry-inlet valve, the slip casting threeway of relief valve connects, carry out the slip casting operation, slip casting front opening slurry-inlet valve, close relief valve, open grouting pump, slurries to the stratum diffusion, are reinforced water blockoff along boring, after slip casting reaches designing requirement, stop slip casting, by anti-gushing water device, the deslagging exhaust plant, orifice tube is proceeded the boring of next section, slip casting again after boring is finished, so boring is one section, whole circulation slip casting section is finished in one section of slip casting, carries out next hole drill hole mortar depositing construction again.
The boring segmentation protrusive grouting for water blocking device that the utility model proposes is applicable to rich current sand of high hydraulic pressure or weak broken water blockoff, bores repeatedly and annotates, and pressure is controlled, the slurries diffusion ratio is more even, and slip casting effect is better, can guarantee to excavate safety, improve speed of application, have bigger popularizing value.
