Abstract
A drilling type aperture control device comprises an aperture pipe (1) embedded in an underground lining structure, a pulp injecting and relieving bypass (2) equipped in the lower part of the aperture pipe exposed part, a gate valve (3) whose one end is connected with the other end of the aperture pipe through flanges, a replaceable elastic sealant backing plate (4) equipped between the flanges, a sealing sleeve pipe (5) connected with the other end of the gate valve through the flanges, a packing (6) equipped inside the sealing sleeve pipe and a sealing pressure tube (7) which the drilling rod traverses to enter into the aperture device, wherein the one end outer edge of the aperture pipe (1) adopts an inverted tooth screw thread structure. The sealing pressure tube (7) is inserted into the sealing sleeve pipe (5) and connected with the sealing sleeve pipe (5) and screwed through a bolt. By the sealing pressure tube (7) to apply axial force on the packing (6), the packing (6) is enabled to enclose the drilling rod, which forms a sealing system.
Description
Technical field
The utility model relates to a kind of brill notes type aperture control device, belongs to carry out carrying out in tunnel and the underground construction artificial stratum freezing hole and creep into the device of laying with frigo.
Background technology
The prominent sand of water burst can appear in the boring that artificial Freezing stratum as rapid need be laid in soft stratums such as similar mud or quicksand usually during construction, soil erosion because drilling hole amount is big, and is compared comparatively dense; A large amount of drilling constructions can cause settlement of stratum, therefore need gushing out of strict underground quicksand of control and water; After having laid freezing hole, need seal slip casting to managing outer hole wall gap or disturbed soil, guarantee that the aperture is anhydrous mobile, form otherwise have influence on frozen soil.Therefore the needs exploitation is a kind of can control underground water and mud flow, can guarantee the aperture control device that drilling rod is constantly pushed ahead again.
Summary of the invention
The purpose of this utility model provides a kind of brill notes type aperture control device, mainly solves and can carry out drilling construction continuously again discontinuously, and lay frigo, lays the problem that the aperture is sealed behind the freezing pipe that finishes.
The technical solution adopted in the utility model is: a kind of brill notes type aperture control device, it is characterized in that: comprise orifice tube, the orifice tube bottom is provided with annotates the plasma discharge bypass, orifice tube one end is connected by flange with an end of gate valve, be provided with removable breathing fluid sealant backing plate between the flange, the gate valve other end adopts flange to be connected with Sealed casing pipe, establishes packing in the Sealed casing pipe, and the sealing pressure pipe is inserted in the Sealed casing pipe and pushed down packing.
Described orifice tube other end outer rim adopts pawl screw thread structure.
One section ring-shaped lug is set in the described Sealed casing pipe,, and can passes through round drill rod as the backstop of packing.
Described notes plasma discharge bypass direction down, external valve.
The technique effect that the utility model reached is: can effectively control underground artesian water blowout and go out, guarantee drilling slurry circulation and retaining wall, frigo is laid the back that finishes aperture slip casting is sealed.
Description of drawings
Accompanying drawing 1 is the sectional drawing that the utility model bores notes type aperture control device.
The specific embodiment
A kind of brill notes type aperture control device, comprise that orifice tube 1 one end outer rims adopt pawl screw thread structure, be embedded in the underground liner structure, the bottom of orifice tube exposed parts is provided with annotates plasma discharge bypass 2, the orifice tube other end is connected by flange with an end of gate valve 3, be provided with removable breathing fluid sealant backing plate 4 between the flange, the gate valve other end adopts flange to be connected with Sealed casing pipe 5, establish packing 6 in the Sealed casing pipe, drilling rod passes sealing pressure pipe 7 and enters opening arrangement, sealing pressure pipe 7 is inserted in the Sealed casing pipe 5, sealing pressure pipe 7 is connected by bolt with Sealed casing pipe 5 and is screwed into, apply axial force by 7 pairs of packings 6 of sealing pressure pipe, make packing 6 hold around drilling rod, form sealing system.
