Abstract
The utility model relates to a water stop needle which comprises a hollow screw cap (1), expansion sleeve tubes (2), an extension tube (4), and an injection mouth (5) with a unidirectional valve. The utility model is characterized in that the expansion sleeve tubes (2) are sheathed on the hollow screw cap (1), the expansion sleeve tubes (2) are two, and the lower part of each expansion sleeve tube is respectively provided with a metal circular ring (3); the extension tube (4) is spirally arranged on the hollow screw cap and is positioned below the metal circular ring (3), and the injection mouth (5) with the unidirectional valve (5) is screwed at the tail end of the extension tube (4). The utility model overcomes the disadvantages that parts of the existing water stop needle is multiple, structure is more complicated and tightly fixed and sealed effect is poor. The utility model has the advantages that clamping and sealing performance is good, when the task is knocked off, the operation is more convenient.
Description
Technical field
The utility model relates to a kind of basement, tunnel or related building of being used for when carrying out sealing leakproof operation, in order to perfusion a kind of Water slop injector that improves structure that blowing agent used.
Background technology
Concrete defect is that hydraulic concrete buildings is more general, one of more common disease, concrete underwater portion particularly, in case produce the underwater concrete defective, to cause leakage of buildings, general modal now promptly is to adopt the mode of " coat (coating) " to completely cut off seepage, but in basement, the tunnel, the building of dam class then can not adopt so mode, because it leaks is because phreatic accumulation, be subjected to simultaneously producing seepage in the slit by basement or related building behind the suitable pressure, this kind seepage never is to adopt coat to solve.
For the seepage in the building that solves basement or tunnel-like, now adopt a kind of specific leak-stopping method, the hole that runs through wall at the position brill one that seepage takes place, then blowing agent is poured into to the wall dorsal part by this hole, utilize blowing agent to meet the characteristic that water is frozen into the foaming shape, can reach the effect of the leakproof that blocks water.
The above-mentioned leakproof operation that blocks water must cooperate a kind of specific facility to carry out, and Chinese patent ZL96248916.6 discloses a kind of Water slop injector, but the component of this Water slop injector reach complexity of more than ten structure; Have only an expansion sleeve, the fit sealing effect is general when being fastened in the hole; Owing to this Water slop injector of the reason on the structure design after blowing agent perfusion is finished, it is disconnected generally to adopt external force that Water slop injector is struck along wall, and then to mend cubic metre of earth formula the slit shutoff is handled, the cumbersome and operation of this processing method has some setbacks again.
Summary of the invention
The purpose of this utility model is to overcome the weak point of existing Water slop injector, and a kind of Water slop injector that improves structure is provided.It adopts two or more expansion sleeve, and the fixing sealing performance is better; After construction finishes, even the parts that only Water slop injector need be revolved change to withdraw from and get final product, and do not need syringe needle is struck disconnected, thereby obtain splendid operation convenience.
The purpose of this utility model reaches by following measure: Water slop injector, it comprise hollow nut 1, expansion sleeve 2, extension 4, have the coupler 5 of one way valve, it is characterized in that described expansion sleeve 2 is sheathed on the nut 1 of hollow, described expansion sleeve 2 has two, all there is metal ring 3 each expansion sleeve 2 below, extension 4 is threaded onto on the nut 1 of hollow, and is positioned at the below of metal ring 3, and the coupler 5 with one way valve is threaded onto the end of extension 4.
In technique scheme, in the described extension 4 screw thread 4-1 is arranged, the screw thread 1-1 on screw thread 4-1 and the nut 1 and have screw thread 5-1 coupling on the coupler 5 of one way valve.
In technique scheme, described extension 4 is a regular hexahedron, and cannelure 4-2 is arranged on the extension 4.
In technique scheme, the cannelure 4-2 on the described extension 4 has two to five.
In technique scheme, an end of the nut 1 of described interior hollow has conehead end 1-2.
The utlity model has following advantage: it adopts two or more rubber system expansion sleeve, and the fixing sealing performance is better; Extension is generally aluminium, and above cannelure is arranged, thereby when striking disconnected operation more convenient operation; Even only extension rotation need be withdrawed from and get final product, and do not need syringe needle is struck disconnected.
Description of drawings
Fig. 1 is the surface structure schematic diagram of an embodiment of the utility model Water slop injector;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of Fig. 1.
The specific embodiment
Describe the performance of the utility model Water slop injector in detail below in conjunction with accompanying drawing, but they do not constitute to restriction of the present utility model, only do for example.
Among the figure 1 for the nut of hollow, 1-1 be screw thread, 1-2 be the conehead end, 2 for expansion sleeve, 3 for metal ring, 4 for extension, 4-1 be screw thread, 4-2 be cannelure, 5 for coupler, 5-1 with one way valve be screw thread.
Consult accompanying drawing as can be known: the utility model Water slop injector, it comprise hollow nut 1, expansion sleeve 2, extension 4, have the coupler 5 of one way valve, described expansion sleeve 2 is sheathed on the nut 1 of hollow, described expansion sleeve 2 has two, all there is metal ring 3 each expansion sleeve 2 below, extension 4 is threaded onto on the nut 1 of hollow, and is positioned at the below of metal ring 3, and the coupler 5 with one way valve is threaded onto the end of extension 4.In the described extension 4 screw thread 4-1 is arranged, the screw thread 1-1 on the nut 1 of screw thread 4-1 and hollow and have screw thread 5-1 coupling on the coupler 5 of one way valve.Described extension 4 is regular hexahedron or cylinder, and a cannelure 4-2 or two to five are arranged on the extension 4.One end of the nut 1 of described hollow has conehead end 1-2.
The utility model Water slop injector is to have Water slop injector now similar when practice, leak at wall earlier and locate pre-subdrilling one hole, Water slop injector is inserted in the wall hole then, then rotate extension, extension promotion metal ring and expansion sleeve are moved forward, expansion sleeve is expanded with support in advance, and make expansion sleeve and the complete driving fit of hole, because of two or more expansion sleeve are arranged, therefore expansion sleeve and hole driving fit performance are better, thereby the blowing agent after more effectively preventing to inject oozes out, then the coupler with one way valve to Water slop injector injects blowing agent, and blowing agent is at the end that enters hole by Water slop injector, and aqueous blowing agent is along the crack infiltration of wall, and meeting the sclerosis of water post-foaming, and fill up the crack of wall effectively.
After construction is finished, operating personnel must be exposed at Water slop injector the outer part of wall and strike disconnected, this moment is owing to have cannelure (can have one or more) on the utility model Water slop injector extension, thereby can conveniently strike disconnected, even only the rotation of the extension of Water slop injector need be withdrawed from and get final product, and do not need syringe needle is struck disconnected, and then, finish the leveling of wall with after mending soil the slit shutoff being handled.Need to prove that extension can be made into the convenient use in practice of the different all size of length.
Need to prove: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite that does not change the utility model principle, this belongs to protection domain of the present utility model equally.
