Abstract
The invention discloses a special hydraulic orifice sealer by an orifice sealed grouting method. The special hydraulic orifice sealer comprises an upper lock sleeve, an outer sealing sleeve pipe, an inner sealing capsule and a three-way lock sleeve, wherein one ends of the upper lock sleeve and the three-way lock sleeve are provided with cylindrical screw threads and conical screw threads and are respectively connected with the outer sealing sleeve pipe and the inner sealing capsule, and an outer-pressing and inner-locking elastic sealing structure is formed. A water inlet nozzle is arranged on the outer sealing sleeve pipe of the elastic sealing structure. During the grouting, water is pressed through a hand pressure water pump, the capsule in the elastic sealing structure generates expansion, and a grouting drill rod is fast sealed. The special hydraulic orifice sealer solves the problems that the orifice sealing and the installation of the existing rubber ball mechanical filling and pressing type sealed structure are inconvenient, and the vertical movement of the grouting rod in the grouting process is limited.
Description
Technical field
The present invention relates to a kind of orifice closure, particularly a kind of " aperture closure grouting method " dedicated water pressure type orifice closure for grouting.
Background technology
" aperture closure grouting method " is used widely in China's grouting works at present as a kind of simple applicable high pressure grouting engineering method.Mainly adopt glueballs machinery inserted enclosed construction (see figure 1) as " aperture closure grouting method " supporting orifice closure at present, by sealing glueballs 11, hold-down bolt 12, friction top 13 sealing grouting drilling rods 10.Generally, so for preventing the long-time grouting generation of admittedly running affairs, generally need in the filling process often to rotate and up and down grouting drilling rod, because the grouting drilling rod connects by a plurality of joints, the body of rod and joint external diameter are variant, the outer short round bur bar through being complementary with the glueballs internal diameter of one of existing glueballs machinery inserted enclosed construction General Requirements special configuration.To this, make troubles to grouting orifice sealing installation on the one hand; The up and down of grouting drilling rod also is subject to certain limitation in the filling process on the other hand.
Summary of the invention
Technical problem to be solved by this invention is, not enough for prior art, a kind of " aperture closure grouting method " dedicated water pressure type orifice closure is provided, solves the aperture sealing of existing glueballs machinery inserted enclosed construction the up and down limited problem of grouting drilling rod in inconvenience, the filling process is installed.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of " aperture closure grouting method " dedicated water pressure type orifice closure, adopt a kind of elastic sealing structure with interior sealing capsule, and described elastic sealing structure is enclosed within on the grouting drilling rod.
As preferred version, described elastic sealing structure comprises lock tube, covering sleeve pipe, interior sealing capsule, threeway lock tube, one end of described upper lock tube, threeway lock tube is with cylindrical thread and tapered tread, described upper lock tube, threeway lock tube all are connected with the covering sleeve pipe by cylindrical thread, described upper lock tube, threeway lock tube all are connected with interior sealing capsule by tapered tread, form a kind of external pressure internal lock elastic sealing structure; Described covering sleeve pipe is provided with the water inlet tap of intaking or discharging water in the elastic sealing structure; Described threeway lock tube lower end is provided with the supporting connecting thread of grouting orifice pipe, and described threeway lock tube is provided with the overfall passage and with the gas thread of the supporting connection of overfall control pressurer system.
As preferred version, described interior sealing capsule adopts high resiliency braided steel wire rubber tube.
By the handlance pump setting-out, make in the elastic sealing structure and expand in the capsule generation, fast the closure grouting drilling rod during grouting.
Compared with prior art, the beneficial effect that the present invention has is: hydraulic type orifice closure of the present invention need not to dispose short round bur bar, and all plain adapter drilling rods all can be used as the grouting drilling rod, and fitting operation is convenient, and sealing is reliable; Can under closed state, directly be in the milk generally speaking in the filling process up and down revolution activity of drilling rod, when if the revolution activity need be passed through the grouting tool joint up and down, can be by the water inlet tap pressure release that discharges water, revolution activity grouting drilling rod up and down behind the quick elastical retraction of interior sealing capsule, fast setting-out sealing after complete, the pressure release retraction switches quick with interior swollen sealing.

The specific embodiment
As shown in Figure 2, one embodiment of the invention adopts a kind of elastic sealing structure with interior sealing capsule, and described elastic sealing structure is enclosed within on the grouting drilling rod; Described elastic sealing structure comprises lock tube 1, covering sleeve pipe 2, interior sealing capsule 3, threeway lock tube 4, described upper lock tube 1, threeway lock tube 4 are all with single head cylindrical thread and tapered tread, described upper lock tube, threeway lock tube all are connected with covering sleeve pipe 2 by the single head cylindrical thread, described upper lock tube, threeway lock tube all are connected with interior sealing capsule 3 by single head tapered tread, form a kind of external pressure internal lock elastic sealing structure; Described covering sleeve pipe 2 is provided with the water inlet tap 5 of intaking or discharging water in the elastic sealing structure; Described threeway lock tube 4 lower ends are provided with the supporting connecting thread 8 of grouting orifice pipe, and described threeway lock tube 4 is provided with the overfall passage and with the gas thread of the supporting connection of overfall control pressurer system.
Hydraulic type orifice closure of the present invention uses flow process as follows:
1, carries out the assembling of hydraulic type orifice closure by structural requirement; Be equipped with handlance pump and be connected leather hose with setting-out; Carry out hydraulic type orifice closure assembling rear enclosed performance test by the structure closure principle, stand-by after the assay was approved;
2, before grouting is lowered to the grouting drilling rod, first sealing threeway lock tube lower end, hydraulic type aperture is connected with the grouting orifice gas thread; The threeway lock tube overfall mouth overfall control pressurer system that is threaded;
3, be lowered in accordance with regulations the grouting drilling rod according to hole depth;
4, water inlet tap connects the handlance pump leather hose, and handlance pump can carry out pressure grouting to hydraulic type orifice closure setting-out (hydraulic pressure is advisable greater than grouting pressure 1MPa) by the overfall control pressurer system behind the closure grouting drilling rod;
5, in the filling process according to grouting situation in the hole, rotate up and down the grouting drilling rod in good time, can under closed state, directly be in the milk the generally speaking up and down rotation of drilling rod, if rotate up and down when needing by the grouting tool joint, can be by the handlance pump pressure release that discharges water, rotate up and down behind the quick elastical retraction of interior sealing capsule, finishing after the rotation more fast, setting-out seals again;
6, grouting complete after, carry out first the handlance pump pressure release that discharges water, behind the quick elastical retraction of interior sealing capsule, extract again the grouting drilling rod, removal hydraulic type orifice closure cleans, sealing capsule abrasion condition in checking maintains intact stand-by.
