By adding the first silk screen 12 and the second silk screen 14 in matrix 1 in the utility model, to substantially increase chance
The whole tensile strength of water expansion sealing strip, ensure that construction quality.
The first glutinous block 21 and the second glutinous block 22 in the utility model are fixed in the glutinous block slot 16 of matrix 1, so that
Glutinous block assembly 2 is linked together with matrix 1, in addition because of the first glutinous block 21 and the second glutinous block 22 cohesive force with super strength and powerful
Creep penetrating power, so that the first glutinous block 21 and the second glutinous block 22 penetrate into the hole of concrete wall 3, therefore by means of
One glutinous block 21 and the second glutinous block 22 enhance the bonding strength of matrix 1 Yu concrete wall 3.
On the one hand the utility model can be played to from concrete by offering guiding gutter 17 in about 1 two sides of matrix
The water oozed out in the crack of wall 3 carries out water conservancy diversion, reduces the hydraulic pressure that water expandable waterstop is subject to, and improves water expandable waterstop
Service life；On the other hand reduce materials, save production cost.
The utility model makes it be not exposed to dust impurity by wrapping up matrix 1 and glutinous block assembly 2 with protective film
In, the cleaning of outer surface is maintained, the destruction not scraped by dust, cement mortar and operation.
It will be appreciated by those skilled in the art that the accompanying drawings are only schematic diagrams of a preferred implementation scenario, module in attached drawing or
Process is not necessarily implemented necessary to the utility model.
It will be appreciated by those skilled in the art that the module in device in implement scene can be described according to implement scene into
Row is distributed in the device of implement scene, can also be carried out corresponding change and is located at the one or more dresses for being different from this implement scene
In setting.The module of above-mentioned implement scene can be merged into a module, can also be further split into multiple submodule.
Disclosed above is only the specific implementation scene of the utility model, and still, the utility model is not limited to this, any this field
Technical staff can think variation should all fall into the protection scope of the utility model.
