Description

Technical Field

[0001] The invention relates to the technical field of building anti-seepage, in particular to a water-bentonite anti-seepage waterstop used for preventing seepage in construction joints of various structures above and below ground. Background Art

[0002] At present, bentonite waterstop strips are used to control water in building gaps. These strips are made of bentonite mixed with colloid and are placed in building gaps. Since the combination of colloid and bentonite limits the expansion coefficient of bentonite, the waterstop effect is poor and true waterstopping cannot be achieved. At the same time, the durability is far from satisfactory.

[0003] In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of bentonite anti-seepage waterstop to overcome the problems existing in the prior art. Summary of the Invention

[0004] In response to the technical problems of the prior art, in which the colloid in bentonite waterstop strips limits the expansion coefficient of the bentonite, resulting in poor waterstopping effect and durability, a bentonite anti-seepage waterstop strip is provided. The present invention primarily utilizes the anti-seepage expansion function of the bentonite material to adapt to bentonite waterstop structures, achieving an integrated anti-seepage effect of the material and structure, providing a permanent waterstop and anti-seepage effect for the building structure.

[0005] The technical means adopted in the present invention are as follows:

[0006] A bentonite anti-seepage water-stopping strip comprises: a long strip tubular bag;

[0007] Furthermore, the tubular bag is filled with bentonite.

[0008] Furthermore, the bentonite used is 200 mesh bentonite.

[0009] Furthermore, the tubular bag is made of PVA film.

[0010] Furthermore, the diameter of the tubular bag is 20-50 mm.

[0011] Furthermore, the wall thickness of the tubular bag is 0.3-0.5 mm.

[0012] Furthermore, a fixed sealing edge is provided on one side of the tubular bag for fixing the waterstop to the building.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The bentonite anti-seepage waterstop provided by the present invention ensures 100% purity of the bentonite by packing the bentonite in a cylindrical bag, and maximizes the water-stopping ability of the bentonite.

[0015] 2. The bentonite anti-seepage waterstop provided by the present invention brings into play the permanent water-stopping ability of bentonite.

[0016] In summary, the technical solution of the present invention solves the problem in the prior art that the colloid in the bentonite waterstop strip limits the expansion coefficient of the bentonite, resulting in poor waterstop effect and poor durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0025] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
