Description
Technical field
The utility model relates to earth-boring Sealing Arrangement technical field, and particularly the moisture unconsolidated formation of high pressure creeps into obturator.
Background technology
The impact of unfavorable geology often can be subject in the Rock And Soil work progress of underground; a large amount of time is spent to go slip casting of punching; cleaning silt etc., at present, drilling technique is widely used in underground construction; this technology relative maturity; but when the moisture unconsolidated formation of high pressure is holed, do not return water when easily creeping into, gush sand, embrace the phenomenons such as brill, substantially increase engineering difficulty; affect programming, even cause engineering accident.
Summary of the invention
The purpose of this utility model is, for above-mentioned problem, provides the moisture unconsolidated formation of high pressure to creep into obturator.
To achieve these goals, the technical solution of the utility model is specific as follows:
The moisture unconsolidated formation of high pressure creeps into obturator, comprise orifice tube 1, large gate valve 2, orifice mechanism 3, little gate valve 4, bleed off pipe 5, it is characterized in that, orifice tube 1 one end arranges flange, described orifice tube 1, its one end side being provided with flange arranges bleed off pipe 5, described bleed off pipe 5, it coordinates little gate valve 4 is installed, described orifice mechanism 3, it comprises drill pipe, sealed tube, sealing ring, described drill pipe, its two ends are provided with flange, and its inner one end arranges joint ring, described sealing ring, it is inner that it is arranged at described drill pipe, and be positioned at joint ring side, sealed tube one end arranges flange, it is inner that the other end is installed on described drill pipe, and contact with described sealing ring, large gate valve 2 one end is connected by the flange of described orifice tube 1 one end and orifice tube 1, the flange of drill pipe one end of other end passing hole mouth mechanism 3 is connected with orifice mechanism 3.
The moisture unconsolidated formation of described high pressure creeps into obturator, it is characterized in that, described orifice tube 1, bleed off pipe 5, its material is steel.
The moisture unconsolidated formation of described high pressure creeps into obturator, it is characterized in that, described orifice mechanism 3, the material of its drill pipe, sealed tube is steel.
The beneficial effects of the utility model are, structure is simple, novel in design, practical reliable, play good sealing function when can creep into the moisture unconsolidated formation of high pressure.
