Detailed Description
The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.
As shown in fig. 1 and 2, a two waterstop structures for lining in tunnel, including tunnel wall 1, waterstop 2 and one deck cement body 3, two layers of cement body 4 of pouring side by side each other, one deck cement body 3 pastes in tunnel wall 1 below and pours, and one deck cement body 3 is close to the one end of two layers of cement body 4 and has seted up arc wall one 5, and two layers of cement body 4 are close to the one end of one deck cement body 3 and have seted up arc wall two 6, and a plurality of sunken holes 9 have inwards been seted up to the inner wall of arc wall one 5.
The water stop 2 is a hollow strip-shaped body with an oval cross section, the two ends of the water stop 2 are sealed, one end of the water stop 2 is provided with an air nozzle 7 communicated with the inside of the water stop 2, the water stop 2 is placed in a path formed by the first arc-shaped groove 5 and the second arc-shaped groove 6, a connector is arranged between the water stop 2 and the first arc-shaped groove 5, the connector can be a bonding agent, and also can be an object which plays a role in connection such as a magnet, a double-faced adhesive tape and the like and does not influence the recovery deformation of the water stop 2.
Air cock 7 is located tunnel wall 1 and is close to ground department, and air cock 7 exposes in one deck cement body 3 or two layers of cement body 4 outsidely, and air cock 7 is arranged in the outside in, can let go up the air cock 7 of blocking up after being convenient for two layers of cement body 4 of later stage pour and accomplish, and the air also can get into waterstop 2 when waterstop 2 self elastic potential energy is replied.
The outer wall of waterstop 2 is equipped with a plurality of bosss 8, boss 8 and 2 inside intercommunications of waterstop, boss 8 can inlay in sunken hole 9, area of contact increase, make waterstop 2 arrange arc wall one 5 in better, in arc wall two 6, when deformation is replied to waterstop 2 of inside evacuation, boss 8 also can expand, can arrange in sunken downthehole 9 more compactly and not run off the position, and waterstop 2 can with arc wall one 5, arc wall two 6 more in close contact with, the stagnant water effect obtains improving.
The specific working principle is as follows: firstly, a layer of cement body 3 is poured and adhered to a tunnel wall 1, after hardening and shaping are carried out for 24 hours, an arc-shaped groove I5 with a sunken hole 9 is milled at one end of the layer of cement body 3 which is about to start pouring two layers of cement bodies 4, air in the water stop 2 is pumped out through an air pump or other equipment connected with an air nozzle 7 of the water stop 2, the water stop 2 is made to be flat, then the air nozzle 7 is blocked by the air pump, an adhesive is coated in the arc-shaped groove I5, one side of the shrunken water stop 2 is adhered in the arc-shaped groove I5, besides the adhesive, magnets can be arranged on a part of a boss 8 of the water stop 2 and in the sunken hole 9, then the water stop 2 can be placed in the arc-shaped groove I5 through mutual adsorption of the boss 8 and the sunken hole 9, and the like, the method is not limited to the two methods, then the two layers of cement bodies 4 are poured and poured from the other side of the water stop 2, the two-layer cement body 4 of 2 opposite sides of waterstop is pasted and is poured in the part that waterstop 2 exposes arc wall one 5 outward, can form an arc wall two 6 like arc wall one 5 naturally and supply the waterstop 2 opposite side to place, pour the back, just also mean that waterstop 2 can not take out, arc wall one 5 and arc wall two 6 all have sunken hole 9, and 2 outer walls of waterstop have the benefit of boss 8, can increase waterstop 2 and arc wall one 5, area of contact between the arc wall two 6, through the embedding cooperation between boss 8 and the sunken hole 9, can expand more tightly in sunken hole 9 when 2 deformation of waterstop are replied, the stagnant water effect is more superior.
Wait 24 hours later, the 4 sclerosis of the two-layer cement body are stereotyped, open air cock 7, the air gets into 2 insides of waterstop again, waterstop 2 begins to reply original state under the assistance of self elasticity and air simultaneously, because arc wall one 5 and arc wall two 6 mill out when being flat according to waterstop 2, so arc wall one 5 and arc wall two 6 have the restriction effect to the waterstop 2 of replying deformation, effect under the three interact is exactly 2 outer walls of waterstop and arc wall one 5, the inner wall of arc wall two 6 is hugged closely all the time and is expanded tightly, thereby play the stagnant water effect. Contrast in the waterstop 2 that prior art level was placed, the emergence of the position phenomenon of running has been avoided, contrast in prior art need toward water 2 in fill water or inflatable waterstop 2, can not have the requirement to aerifing or the pressure of filling water, the phenomenon that there is too big atmospheric pressure or water pressure too big to lead to waterstop 2 to burst to appear, only rely on self deformation power to reply and tightly play fine stagnant water effect to the support of an arc wall 5 and two 6 walls of arc wall, and simple effective in the construction, therefore, the carrier wave prepaid electric energy meter is low in cost, and has wide application prospect.
The first and second arc-shaped grooves 5 and 6 are not limited to arc, but may be U-shaped, 21274, triangular, polygonal, etc. similarly, since the waterstop 2 is made of rubber material, it has excellent deformability, and the cross section is not limited to oval, polygonal, circular, etc.
