Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is described in further detail by detailed description of the invention:
Embodiment 1: seeing Fig. 1 to Fig. 5, the elastic fetalism hole packer of a kind of braiding, including fetalism sealing of hole set 7 and flexible grout joint 3, described flexible grout joint 3 connects with the sealing of hole chamber of described sealing of hole set 7, and this flexible grout joint 3 is by slip casting adapter 301 and horizontal stroke Cross section is that the casting head 302 of flat tube shape is constituted, and described slip casting adapter 301 and casting head 302 are by injection moulding integrated molding, described note Slurry 302 is positioned at slip casting adapter 301 front end, and its inwall is provided with backstop structure 5, and described backstop structure is fish gill-like backstop structure (as shown in Figures 2 and 3).Described sealing of hole set two ends carry out micropore sealing treatment and form micropore blind end 9, micropore sealing treatment ratio As impregnation water-proofing treatment or spray treatment can be carried out, as long as the technique being possible to prevent sealing of hole to overlap 7 two ends infiltrations can be adopted With, this sealing of hole set 7 is for including cylindric sealing of hole set body, and described sealing of hole set includes cylindric sealing of hole set body, described cylinder One end of shape sealing of hole set body is pulled to the other end inside it or outside it, and two end interfaces are sewed up formation fetalism sealing of hole set, Sewing up the sealing of hole set body after port and form internal layer and the outer layer of sealing of hole set, it is envelope that sealing of hole overlaps the closing cavity in the middle of inside and outside layer Vestibule, described sealing of hole set body two ends are sewed up interface and are adjusted to sealing of hole set internal layer.Described sealing of hole set body uses high-strength line double Rib-loop circle is compiled craft woven and is formed, and through fire-retardant, antistatic treatment, uses the sealing of hole set body that above-mentioned material becomes with craft woven Diameter may be expanded to 2.5 to 3 times of green diameter, pressure bring up to 2 to 3 MPas.Above-mentioned high-strength line can use automobile Tire cord fabric embryo line and high-strength nylon embryo line etc..
Embodiment 2: embodiment 2 is essentially identical with embodiment 1 structure, and something in common does not repeats, except for the difference that: in order to improve Fastness in place of filling adaptor 3 and sealing of hole set connection, the described latter half of outer wall of casting head 302 is fixed with discoid fixing Sheet 10, this filling adaptor is fixed on sealing of hole set 7 by described stator 10, and described stator 10 is by by hot melt adhesion method The discoid stator of filling adaptor is fixed on sealing of hole set body, it is possible to reinforce further with lockstitch.Certainly, in order to Simplified flowsheet, it is also possible to casting head 302, slip casting adapter 301 and discoid stator 10 are passed through injection moulding integrated molding.
Embodiment 3: see 1 and 5, in order to improve the counterflow-preventing effect of flexible grout joint 3 and self-enclosed effect, described Casting head 302 outer sheath is clamped on casting head 302 outer wall equipped with flat spring 6, described flat spring 6.Described flexible grout joint 3 Form self-enclosed check valve-type elasticity filling adaptor with flat spring 6 combination, improve the reliability of the present embodiment work.
The present invention is woven elastic fetalism hole packer and is made by following manufacture method, particularly as follows:
Step 1: braiding sealing of hole set body: use high intensity line (such as automobile tire cord fabric embryo line or high-strength nylon embryo line) Compile craft woven through double rib circle and become cylindric sealing of hole set body;
Step 2: filling adaptor is fixed on sealing of hole set body: near one end on the sealing of hole set body that will obtain in step 1 Casting head, as the connecting hole of connection flexible grout joint, is penetrated sealing of hole intracavity by connecting hole, passes through hot melt by position punching Casting head is fixed on sealing of hole set body by bonding method;
Step 3: make fetalism sealing of hole set: the sealing of hole of the fixing upper flexible grout joint obtained in step 2 is overlapped one end of body It is pulled to the other end inside it or outside it, two end interfaces is sewed up and forms the elastic fetalism sealing of hole set of braiding;
Step 4: sealing of hole is overlapped two ends and carries out water-impervious process;
Step 5: packaging hole packer: first, the hole packer obtained in step 4 is sleeved on antistatic gas drainage pipe;Then, Filling adaptor is sewed up with hole packer body two ends and is pressed between hole packer and gas drainage pipe together with interface, fixed;? After, cover whole hole packer and gas drainage pipe with antistatic shrink-packaging's film, carry out heat sealed package.
Being additionally provided with stator 10 on described casting head outer wall, the part before this casting head is positioned at described stator is passed through Connecting hole is sleeved in the sealing of hole chamber of sealing of hole set, and described stator is bonded on hole packer body by hot melt adhesion method, and leads to Cross lockstitch and carry out sewn reinforcement.It is set with flat spring on described casting head outer wall, set is loaded onto the filling adaptor of flat spring It is secured together with sealing of hole set body, particularly as follows: casting head first half set is loaded onto the flat spring that shape is matched, described Flat spring is clamped on casting head outer wall, and flat spring is sleeved on together with casting head the sealing of hole chamber of sealing of hole set by connecting hole In, and be fixed on sealing of hole set body by hot melt adhesion method.
In step 3, sewing up the sealing of hole set body after port and form internal layer and the outer layer of sealing of hole set, sealing of hole overlaps in inside and outside layer Between closing cavity be sealing of hole chamber.
Using the present invention to weave the method for sealing of elastic fetalism hole packer, step is as follows:
Step 1: Grouting Pipe is connected in the slip casting adapter of flexible grout joint, whole hole packer is inserted in gas extraction hole To the technological design degree of depth, injection slurry injecting through Grouting Pipe and filling adaptor with grouting pump the sealing of hole intracavity of sealing of hole set, slip casting is arrived Set pressure and after pressurize a few minutes, terminate slip casting, extract Grouting Pipe out;
Step 2: after slip casting terminates, the pressure in flexible grout joint declines, and in flat spring and sealing of hole overlap, slurry pressure is double Under recast, flexible grout joint seal itself, prevention slurry reflux, keep the pressure of braiding elastic fetalism sealing of hole set intracavity, Until sealing of hole serosity microdilatancy solidify (as shown in Figure 6), complete sealing of hole operation.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way Restriction, as long as have employed the method design of the present invention and the improvement of various unsubstantialities that technical scheme is carried out, or without changing Enter and design and the technical scheme of the present invention are directly applied to other occasion, all within protection scope of the present invention.
