Description
Technical field
The utility model belongs to the reinforcing and the water-plugging technique of tunnel and underground construction weak surrounding rock, mainly proposes a kind of Drilling rod back sublevel grouting device of.
Background technology
In the weak broken water bearing ground, 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, cause that the face of land caves in when serious, groundwater table decreasing 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, for applying of supporting and protection structure creates conditions.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, the slip casting of segmentation retrusive.Segmentation retrusive grouting method is divided into the segmentation retrusive slip casting of mounting sleeve and mounting sleeve not again, and hole wall directly ends the segmentation retrusive slip casting of slurry.The method of the segmentation retrusive slip casting of mounting sleeve generally is applicable to shallow bore hole slip casting, and during as hole depth, slip casting core pipe and stop grouting plug block easily, are difficult to extract.The method that hole wall directly ends the segmentation retrusive slip casting of slurry generally is suitable for more complete hole wall, more as slit on the hole wall, connective each other strong, to at the bottom of the hole or during centre portion slip casting, slurries return the stop grouting plug rear portion easily from the stratum, embrace core pipe and stop grouting plug, cause stop grouting plug to lose efficacy, can't retreat, influence slip casting effect.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of Drilling rod back sublevel grouting device of, makes it can satisfy the requirement that drilling rod retreats segmenting slip casting.
The utility model is finished its invention task by the following technical solutions: this device mainly comprises rig, grouting pump, drilling rod, orifice tube, anti-gushing water device, deslagging exhaust plant, ends slurry tube and stop grouting plug; Orifice tube one end is positioned at the aperture of boring and is fixed on the hole wall by the anchoring agent, the other end is positioned at outside the boring and connects the deslagging exhaust plant and be connected with anti-gushing water device at deslagging exhaust plant rear portion by flange by flange, anti-gushing water device rear portion by flange with end slurry and tin connect, end in the slurry tube stop grouting plug is set, stop grouting plug is the hollow frustum structure by hole enlargement behind the forward direction, and only slurry tube its rear end large-diameter pipe of reducer pipe structure connects with the hollow platen by flange makes stop grouting plug be compressed by the hollow platen; The drilling rod rear portion of hollow is communicated with inlet pipe and water inlet pipe respectively.
The utility model slip casting course of work: bore shallow bore hole by rig, withdraw from drilling rod, in drilling orifice, install and fix orifice tube, and connection is gone up deslagging exhaust plant, anti-gushing water device and ended slurry tube, stop grouting plug etc.; The flange plate bolt that connects with the hollow platen of counter-rotating loosens stop grouting plug, continues boring to designing at the bottom of the hole behind the position (the edge joint long drill pipe is bored on the limit), connects supply channel will hole interior silt particle and rock dust discharge; Tightening flange plate bolt makes the hollow platen compress stop grouting plug, it is expanded seals tight drilling rod and ends the gap of starching between the tube inwall, close water supply valve, open for slurry valve and begin slip casting, slurries are delivered at the bottom of the hole by drilling rod, and return to the hole along the space between drilling rod and the hole wall, by the stop grouting plug shutoff, and rear slurry begins to spread in the stratum; When grouting pressure and grouting amount reach design, can retreat the drilling rod certain distance, carry out the slip casting of next section, backstep is suitably adjusted apart from eating slurry amount size according to the stratum, drilling rod is drawn back so step by step, the stratum is all withdrawed from all drilling rods at last from progressively being reinforced to the aperture at the bottom of the hole, sets up grouting device again and carries out the disposable additional slip casting in full hole.(orifice tube is stayed in the boring) all unloaded grouting device in slip casting after finishing, withdraw from drilling rod, can begin the slip casting of creeping in next hole.
Its structure design of the device that the utility model proposes is simple, and applicability is strong, and is easy and simple to handle, can realize drilling rod retrusive segmenting slip casting and make pressure controlled, reaches slip casting effect preferably, has bigger popularizing value.
