The groove 41 of conjunction, and then after sealing ring 4 is placed on into the outer wall of socket 2, firmly engage projection 23 and groove 41, and then sealing ring
4 outer walls for being not easily disconnected from socket 2 simultaneously slide.
As shown in figure 3, the forward direction injected hole 6 in grouting is inserted into high pressure Water slop injector 7, high pressure Water slop injector 7 utilizes ring
Solid principle is compressed, head is provided with unidirectional stop valve, can prevent elastic sealant from falling to spray under high pressure pushing, it is to avoid be elastic close
Sealing is wasted, while in filling process, can suitably increase certain grouting pressure, so that the elastic packing in grouting cavity
Glue is more closely knit, with more preferably sealing effectiveness.
As shown in figure 4, the upper end outer wall in high pressure Water slop injector 7 is provided with card in the storage tank 72 of ring-shaped, storage tank 72
Rubber ring 71 is embedded with, rubber ring 71 is sealed in the gap between the inwall of injected hole 6 in the outer wall of high pressure Water slop injector 7 and Fig. 3,
With sealing effectiveness, then in filling process, elastic sealant is difficult to be spilt from the gap, in the situation of better tightness
Under, elastic sealant can fill more closely knit in grouting cavity, further increase the close of elastic sealing layer 5 in Fig. 3
Envelope effect.
As shown in figure 5, the outer wall of rubber ring 71 is integrally formed with multiple annular ridges 711, adjacent annular ridge 711 it
Between there is certain interval, annular ridge 711 includes contacting at the arc surface 7111 of the madial wall of injected hole 6 in Fig. 3, arc surface 7111
Be conducive to Fig. 4 mesohighs Water slop injector 7 and rubber ring 71 to slip into injected hole 6, accelerate installation effectiveness.
Installation process, the polish inwall of bellmouth 1 and the outer wall of socket 2, and hair side 8 is formed, then brushed on hair side 8 many
Road nano microcrystalline material simultaneously forms rigid seal back-up coat 3, after treating that rigid seal back-up coat 3 is fully cured, sealing ring 4 is consolidated
Due to after caulking groove 21, the inwall of outer wall, the outer wall of sealing ring 4 and bellmouth 1 in socket 2 smears a small amount of vaseline, and will
Socket 2 is aligned and inserts in bellmouth 1, until the end of socket 2 contacts at limited block 9, in the outer wall brill injected hole 6 of bellmouth 1, and to
Injected hole 6 is inserted into high pressure Water slop injector 7, then injects elastic sealant to being in the milk in cavity by high-pressure grouting machine, and is formed
Elastic sealing layer 5.Again in the outer wall brushing nano microcrystalline material of bellmouth 1, and form rigid reinforcing layer 10.The utility model passes through
Limited block 9, sealing ring 4, elastic sealing layer 5, rigid seal back-up coat 3 and the multiple waterproof construction of rigid reinforcing layer 10 are prevented
Ooze, with preferably sealing effectiveness.
