Abstract
Provided is a strain transducer installation and fixing device which can be used in a borehole. The whole device comprises a rubber bag, a hollow sealing bolt, a sealing nut, a bulkhead screw cap, a cable waterproof connector, an injection pipe connector, and an injection pipe. The rubber bag is connected with the hollow sealing bolt and the sealing nut at a bore position at one end. The bulkhead screw cap and the hollow sealing bolt are connected via a screw thread. The bulkhead screw cap is connected with the cable waterproof connector and the injection pipe connector via an inner thread hole disposed in the bulkhead screw head. When the device is used, the strain transducer is placed in the device, and the strain transducer data transmission cable is led out from the device via the cable waterproof connector. When the whole device is placed in the designed testing depth of the borehole, the inner cavity of the rubber bag is injected through the injection pipe of the device, and then after the solidification of the grout, an integrated structure of the strain transducer, the grant solidification body and the hole wall of the borehole is formed, and the strain measurement can be conducted.
Description
Affiliated technical field
The utility model relates to strain transducer fixing device for installing in a kind of boring, especially can realize strain transducer Fast Installation and stable stationary device in boring.
Background technology
In boring, conventional strain ga(u)ge type sensor is column at present, such as looking like utility model patent: a kind of for testing the sensor (patent No.: ZL201220044301.0) of adopting seat earth deformation extent.For this type sensor at present conventional installing and fixing method be: at strain transducer, transfer in boring after the design test degree of depth, from drilling orifice cement injection slurries or chemical grout, strain transducer is submerged in slurries, after slurries solidify, form the structure of sensor, slurry consolidation body, borehole wall one, then realize the measurement to strain.Above-mentioned method has two large defects, and the one, when the water outlet of boring nature, the slurries of perfusion are just easily watered down when uncured, and the solidification intensity of final slurries and stability, by variation, have also just finally affected the accuracy of strain testing; The 2nd, for boring hole depth upwardly extending situation, then while adopting the method from aperture perfusion, slurries cannot enter boring, also just cannot realize the installation to sensor.
Utility model content
In order to overcome the deficiency of strain transducer installation method in conventional boring, the utility model provides strain transducer fixing device for installing in a kind of boring, this device can not only customer service during boring water outlet strain transducer measure the inaccurate and boring problem that strain transducer cannot adopt grouting to install upwards time, and can realize sensor Fast Installation and stable fixing.
The utility model solves the technical scheme that its technical matters adopts: in boring, strain transducer fixing device for installing structure comprises rubber pocket, hollow envelope capsule bolt, envelope capsule nut, silently silk cap, Waterproof connector of cable, Grouting Pipe joint, Grouting Pipe.Wherein rubber pocket is built and is formed by rubber, is open column shape, one end perforate; Silently on silk cap, screw thread and hollow envelope capsule bolt screw thread coincide; Silently on silk cap, open two internal thread holes, one of them is positioned at a cap middle position, and another position does not have specific (special) requirements, and middle position internal thread hole and Waterproof connector of cable screw thread coincide, and another internal thread hole and Grouting Pipe joint screw thread coincide; Hollow envelope capsule bolt, envelope capsule nut are realized and being connected of rubber pocket by Suo Kai hole, rubber pocket one end; Hollow envelope capsule bolt and silently silk cap are by male and female screwed connection; Waterproof connector of cable, Grouting Pipe joint are connected respectively by two internal thread holes on silk cap silently and a silk cap silently; Grouting Pipe is connected with Grouting Pipe joint.
Before this device is used, keep hollow envelope capsule bolt, envelope capsule nut to be connected with rubber pocket, Grouting Pipe joint is connected with a cap silently, and other parts are all in released state.During concrete use, be divided into sequentially following four steps: 1. strain transducer data cable is oppositely passed to the silently hole of silk cap central authorities, and then pass Waterproof connector of cable and tighten sealing adaptor, screwed connection by silently institute of silk cap central authorities perforate is silk cap and Waterproof connector of cable silently, so just realized the sealing to cable, can effectively anti-sealing and gas by cable and the Clearance Flow of institute of silk cap central authorities perforate silently; In this step, be according to the length of rubber pocket, the sensing data transmission cable of reserved suitable length, the length of pre-testing cable is advisable with the length of 1/2nd rubber pockets; 2. hollow envelope capsule bolt with silently silk a cap by male and female screw thread, be closely connected; 3. extract out or extrude the air in rubber pocket with hand, then Grouting Pipe is closely connected with Grouting Pipe joint; 4. the design of the device of in-built sensor being transferred to boring fathoms, from Grouting Pipe, inject chemical grout or cement grout, grouting amount will equal or be slightly larger than the volume of rubber pocket complete expansion, and the flocculation time of slip casting slurries used must not be shorter than the time that slip casting process consumes.Complete the structure that above-mentioned four steps have just formed strain transducer, slurry consolidation body, borehole wall one after slurries fully solidify, also just can carry out strain measurement.
The beneficial effects of the utility model are, can customer service during boring water outlet routine aperture grouting method fixedly unstable the and boring of strain transducer upwards time strain transducer cannot adopt the problem of grouting installation, can realize sensor Fast Installation and stable fixing, and simple in structure, easy to operate.
