Description

and a package of disc springs alternating with washers, which is installed in the cylinder with the ability of one of the ends to interact with the locking element of the safety valve, and the other with the adjusting nut of its adjustment, each spring has an axial hole, a washer - side, and in the saddle the valve is made an additional, hole for the solution component.

FIG. 1 shows the hardening pattern of the hotplates in FIG. 2 shows an apparatus for carrying out the method; in fig. 3 shows section A-A in FIG. in fig. 4 shows a section BB in FIG. 2j in FIG. 5 is a section bb of FIG. 2.

The injection of the reinforcing solution is carried out by an injection unit 1, which includes a pump 2 for resin and a pump 3 for the hardener, supplying pipes 4 and 5 with pressure gauges; 6 and 7, an adapter 8 and a supply sleeve 9. Inject the injector with a sealer 10 into which a removable mixer 11 is mounted. A flexible metal conduit 12 is passed inside the inlet sleeve 9 and the sealer 10. The sealer 10 includes a sealing sleeve 13 , end cups 14 and conical nipples 15 for clamping sealing sleeve 13 and connecting with inlet sleeve 9 and mixer 11. Internal flexible metal conduit 12 passed through supply sleeve 9 and sealer 10 is connected, for example, by soldering with a tip ohm 16. Tip 16, with a seat valve, is provided with an axial channel 17 connected to an internal pipe 12, a series of side channels 18 for connection to a cavity 19 and a shoulder 20. Removable mixer 11, which is also a safety valve, consists of a housing 21, made in the form of a hollow cylinder, in which the shoulder 20 of the tip 16, the locking element 22 of the safety valve, the mixing element in the form of a package of belleville springs 23 and washers 24, the adjusting nut 25 Package bags, which are secured from turning by means of a figure washer 26, spring washer 27 and bolt 28. Cup springs 23 with axial holes 29 and washers 24 with bob holes 30 are installed in an alternating flow pattern to create a turbulent flow of reinforcing solution. The mixing element from the package of disc springs and washers is the spring of the safety valve. The locking element 22 of the safety / valve is made with a flat working surface that covers all the channels in the saddle of the tip 16, with

side grooves 31 for passing the components of the solution and the shoulders .32 to prevent it from falling out of the mixer body. The adjusting nut 25 of the setting of the safety valve is made with outlets 33.,

When assembled, the mixer 11 is threaded onto the threads of the conical: nipple 1b of the sealer 10, while sealing the sealing ring 34 and the shoulder 20 of the tip 16. The locking element 22 sits on the flat saddle of the tip 16 and closes all the channels for the resin and hardener.

The strengthening of rocks according to the proposed method is carried out as follows.

assembled and connected to the injection unit 1, becoming from the supplying Tpy6onpOBOjEXOB 4 and 5, the sleeve 9, the sealer 10 and, the mixer 11 is introduced into the well 35 to the required depth, simultaneously turn on the pumps 2 and 3 of the injection unit 1, spreading the sealer at a pressure, for example 4-4 MPa (pressure setting of the safety valve), and inject the required amount of reinforcing solution into the well, which consists, for example, of the components that follow,% by volume

The synthetic resin solution flows under the closure element 22 in the following way: from pump 2 through supply pipe 4 through adapter 8 to cavity 19 and from it to side channels 18 of tip 16, and hardener solution from pump 3 through supply line 5 through perhodnik 8 - into the internal flexible metal conduit 12 and from there into the axial channel 17 of the Tip 16. After the sealer expands into the well-bore with a solution of synthetic resin, the locking element 22 of the safety valve and the components of the reinforcing solution are opened sideways vym its protochkam31 fed to the mixer and run through openings 29 and 30, disc springs 23 and washers 24, between a mixing Referring in one way and then the reinforcing ready solution enters the well through the passages 33 of the adjusting nut 25.

After pumping the required amount of reinforcing solution into the well, the pumps 2 and 3 stop, the closure element 22 closes the sleeves 17 and 18 in the tip 16, isolates the solution components from each other, relieves the pressure of the resin solution in the cavity 19 (the drain valve opens for a while pump 2), the assembled stand is removed from the well, poured out of the mixer by tilting the remains of the reinforcing solution and pressurizing into the next well or rolling to a coil and placing it at the injection unit. Mixer 11 is prevented after a while for time, reduced, disassembled and washed. Claims 1. The method of strengthening rocks, including the introduction of an injector with a condenser into the well, spreading the sealant and pumping it into the array separate pipelines and mix them at the exit and of the injector, which is of a kind, so that, in order to simplify the technological scheme of strengthening of rock formations, the radpore of the sealer is produced by pressure of one of the components 2. A device for strengthening the rocks, including a mixer and an injector with a well sealing / which has a safety valve with a locking element, an adjusting adjustment nut and an opening for the pacTBojxa, placed in its saddle, o / t l and h This is due to the fact that the mixer is mounted in a pressurized seal at its outlet and is made in the form of a hollow cylinder and a package of disc SPRINGS alternating with the shields, which is installed in the cylinder with the ability of one of the ends interacting with the locking element -enforcement of the valve, and the other - with an adjusting nut its settings, wherein each diaphragm spring has an axial bore, washer - side, and the saddle valve performance {1 holds additional opening for the solution components.
