Abstract
The utility model belongs to the reinforcing and water shutoff technique of tunnel and underground engineering weak enclosing rock and provides an aperture pipe for high hydraulic mud injection, which is characterized in that an aperture pipe 2 is a seamless steel pipe with the outer diameter of Phi108mm, the wall thickness of 6mm and the length of 1.5m, one end of the aperture pipe 2 is welded with a flange disc 7, the other end is sealed into a caecal tube structure with cement mortar 6, the pipe wall of the aperture pipe 2 is provided with flax silk 4 which is twisted in a spindle mode, the aperture pipe 2 is located in a drill hole 3 with the depth of 2.0m on a grouting wall 1 or a grouting disc, and the space between the aperture pipe 2 and the pore wall of the drill hole is filled with sulphoaluminate cement mortar. The aperture pipe which is proposed by the utility model can satisfy the mad injection demands with the maximum pad injection pressure of 10Mpa.
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 orifice tube that is used for high hydraulic pressure slip casting.
Background technology
Carry out tunnel and underground engineering construction in bad geological section especially high pressure, rich pool, water under high pressure in the stratum or water under high pressure very easily occurring carries charges such as silt and gushes out from the excavation face, jeopardize personnel and device security, casualty accident in various degree takes place, and cause groundwater table decreasing, soil erosion damages surrounding enviroment, brings to resident's productive life to have a strong impact on.For guaranteeing construction safety and reaching environmental requirement, processing method commonly used is a slip casting method both at home and abroad at present, 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.For preventing that underground water is gushed out in the boring procedure, guarantee boring, slip casting safety, need in advance at wall for grouting or end on the magmatic rock dish orifice tube is installed and anchoring firm, gate valve is installed then, hole again, anchorage style relatively more commonly used at present is to put the anchoring agent at tube wall place, orifice tube aperture, in case of necessity at aperture peace flange, at wall for grouting or end and beat anchor pole on the magmatic rock dish and orifice tube is anchored in the boring this method complex process, the anchored force that provides is limited, the pulling capacity that orifice tube is subjected in the time of can not resisting high-pressure slip-casting is difficult to realize high-pressure slip-casting, can't guarantee slip casting effect, and orifice tube easily is ejected in the slip casting process, causes bigger potential safety hazard.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of orifice tube that is used for high hydraulic pressure slip casting, makes it can satisfy that grouting pressure is the requirement of the high-pressure slip-casting of 10Mpa under the high hydraulic condition.
The utility model is finished its invention task in the following ways: a kind of orifice tube that is used for high hydraulic pressure slip casting, orifice tube is the seamless steel pipe of external diameter φ 108mm, wall thickness 6mm, length 1.5m, and orifice tube one end welding flange, the other end constitute the blind pipe structure by the cement mortar shutoff; Have the flax silk that twines with the spindle pattern on the tube wall of orifice tube, described orifice tube is positioned at wall for grouting or ends the dark boring of 2.0m on the magmatic rock dish, and between the hole wall of orifice tube and boring filling sulphate aluminium cement slurries.
Description of drawings
The user mode schematic diagram of Fig. 1 for adopting the utility model orifice tube the aperture to be carried out anchoring.
Among the figure: 1, wall for grouting, 2, orifice tube, 3, boring, 4, flax silk, 6, cement mortar, 7, flange, 8, reducer pipe.
The specific embodiment
In conjunction with the accompanying drawings the utility model embodiment is illustrated:
As shown in Figure 1, orifice tube 2 adopts the seamless steel pipe processing of external diameter φ 108mm, wall thickness 6mm, length 1.5m, and tube wall twines flax silk 4 by the pattern of spindle, mouth of pipe welding flange 7, and the pipe end, utilize cement mortar 6 shutoff, constitutes the blind pipe structure; Utilization is furnished with the rig of φ 130mm drill bit and goes up the dark hole of brill 2.0m at wall for grouting 1 (or ending the magmatic rock dish), put into the sulphate aluminium cement slurries of water/binder ratio W/C=0.3～0.4: 1 in 3 in boring, the amount of putting into is advisable to be full of 2/3 of boring length, after treating cement mortar 6 curing at the 2 pipe ends of orifice tube, adopt rig to be connected with reducer pipe 8, orifice tube 2 is headed in the boring 3, extruding sulphate aluminium cement slurries make it fully fill space between tube wall and hole wall, treat that the sulphate aluminium cement slurries solidify the anchoring of then having finished orifice tube after about 2h.
