Problems solved by technology

However, if you want to use this sealant as a waterproof layer, according to the relevant standards, the net content of bentonite in it is far from enough. In order to make the content of bentonite in it meet the waterproof requirements, its thickness will be very large, making it impossible to fix the waterproof blanket.

Embodiment 1

[0079] A waterproofing system such as figure 1 As shown, the waterproof system is composed of concrete structure base 1, bentonite clay layer 2, PE film 3 and bentonite waterproof blanket 4 from the concrete structure base to the outside, wherein the bentonite waterproof blanket 4 constitutes the first waterproofing; bentonite clay layer 2 It is composed of continuous and uniform bentonite clay, which constitutes the second waterproofing of the present invention. At the same time, under the pressure of the backfill soil layer 5 and the protective layer, the bentonite clay has been squeezed and combined with the concrete, and some will penetrate into the void of concrete to form a third waterproofing. It should be noted that the double-layer waterproofing of such a structure is by no means a simple superposition of double-layer waterproofing. It is essentially different from the waterproof system constructed with double-layer waterproof blankets. Taking the waterproof project ...

Embodiment 11

[0087] A bentonite waterproofing system such as figure 2 As shown, it is composed of concrete cushion 6, non-woven fabric layer 41, bentonite layer 43, woven fabric layer 42, PE film 3, bentonite clay layer 2 and concrete structure base 1 from bottom to top. Bentonite clay can be directly covered on the PE film.

[0088] The bentonite waterproofing system of this embodiment is suitable for base plate construction, that is, before the concrete construction of the building, some special parts need to be waterproofed first, and then the base plate is used. During the construction of the bottom slab, due to the concrete structure layer, it does not exist (no construction). At this time, the bentonite cement can be replaced by bentonite particles. During the waterproof construction of the bottom slab, after the steel bars are bound, spread the bentonite particles evenly under the steel bar layer. .

Embodiment 12

[0090] A bentonite waterproofing system is different from the above-mentioned embodiments in that bentonite powder is attached to the surface of the bentonite clay layer 2 .

Abstract

The invention provides a bentonite waterproof system and a construction method thereof. The bentonite waterproof system includes a bentonite waterproof blanket. The waterproof blanket includes a non-woven fabric layer, a bentonite layer and a woven cloth layer, and also includes bentonite clay. The bentonite clay is combined with Concrete structure base contact. The construction method of the bentonite waterproof system includes fixing the bentonite waterproof blanket on the surface of the concrete structure base, and evenly covering the surface of the concrete structure base with a bentonite cement layer. In the bentonite waterproof system and the construction method of the bentonite waterproof system provided by the present invention, the bentonite waterproof blanket constitutes the first waterproofing, and the bentonite mastic layer and the bentonite mastic infiltrated into the base layer of the concrete structure constitute the second and third waterproofing, so that the original single layer The waterproof has become multi-layer, which greatly improves the reliability of waterproof. At the same time, because the bentonite clay layer and its penetration into the concrete structure base, it also has the performance of preventing water crossing, and has the effect of anti-drainage combination, and has a wider range of applications.

Description

technical field [0001] The invention belongs to the field of building waterproofing, and in particular relates to a bentonite waterproofing system and a construction method. The waterproof system can be widely used in waterproof and anti-seepage construction in municipal, highway, railway, water conservancy, environmental protection and industrial and civil buildings, especially suitable for underground waterproof and anti-seepage projects of structures with concrete structures. Background technique [0002] In construction engineering and civil engineering, in order to ensure the use function of the building and the durability of the engineering life, to prevent the penetration of water into the structure or the outflow of sewage to the outside, it is necessary to use appropriate waterproof materials to block, and at the same time use The correct way to carry out construction. Practice has proved that no matter how good the waterproof material is, it needs to be equipped w...
