Description

Cement blanket

Technical Field

The utility model relates to a material for building specifically is a cement blanket.

Background

The existing cement blanket generally comprises a net structure consisting of a top layer, a bottom layer and a connecting layer, wherein the top layer, the bottom layer and the connecting layer enclose a cavity, and cement-based dry powder is filled in the cavity. After the cement blanket is constructed, the cement blanket can be solidified when meeting water to form a concrete-like structure, and is firm and durable. However, the existing cement blanket has the defects of complex structure and high production cost, and the cement-based dry powder needs special equipment for filling.

Disclosure of Invention

The utility model aims to solve the technical problem that, to the not enough of prior art, provide a simple structure, low in production cost, construction convenience's cement blanket.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the cement blanket comprises a bottom layer, a velvet layer and a permeable top layer, wherein the velvet layer and the permeable top layer are arranged on the bottom layer, the top layer is compounded on the velvet layer, and a cement-based composite material is filled in the velvet layer.

Preferably, the bottom layer is a waterproof film or a water permeable film. In some projects that allow water penetration, a cement blanket with a water permeable membrane as the bottom layer may be used. In the project which does not allow water seepage, a cement blanket with a waterproof film as the bottom layer is used.

Preferably, the cement-based composite material is cement-based dry powder filled into the wool layer at a construction site, or, preferably, the cement-based composite material is cement paste sprayed into the wool layer at the construction site, depending on construction requirements and construction environment.

Preferably, the pile yarn layer is composed of a plurality of pile yarn bundles, and the pile yarn bundles are arranged on the bottom layer at intervals.

Preferably, the plurality of tow bundles are arranged on the bottom layer at equal intervals, and the distance between two adjacent tow bundles is 2-50 μm.

Preferably, the wool layer is made of fibers, so that the filling effect and firmness of the cement-based composite material are ensured.

Furthermore, the velvet layer is formed by blending glass fibers and polyester fibers, and the bottom layer is formed by hot-pressing or gluing the glass fibers and the polyester fibers. The bottom layer and the velvet layer can ensure the ductility, the elastic recovery capability and the strength of the cement blanket, can ensure the wrinkle resistance, the thermal stability, the corrosion resistance and the mechanical strength of the cement blanket, and avoid hair sticking.

Preferably, the floss layer is arranged on one side of the bottom layer through a drawing process or a gluing process. The velvet layer is connected with the bottom layer through a gluing process, so that the bottom layer and the velvet layer can be conveniently and independently transported, the bottom layer can be laid firstly during construction, and then the velvet layer and the bottom layer are glued together, so that the velvet layer is flexible and convenient.

Preferably, the gram weight of the cement blanket is 5-14 kg/m²The thickness of the bottom layer is 1-4 mm, and the thickness of the velvet layer is 3-12 mm. 5 to 14 kg/m²The ductility, the flexibility and the strength of the cement blanket can be ensured by the gram weight of the cement blanket and the thickness of the bottom layer of 1-4 mm, and the cement blanket can be conveniently supplied in a rolled manner. The thickness of the floss layer of 3-12 mm can ensure the filling thickness and the filling effect of the cement-based dry powder.

Compared with the prior art, the utility model has the advantages of as follows: the utility model discloses a cement blanket simple structure, the supply of goods form can be forms such as coiled material, sheet, its manufacturing cost has more had the cement blanket can reduce more than 50%, construction convenience, and is environment friendly, and the durability is good, can be applied to railway and highway bank protection along the line and curb laying, all kinds of irrigation canals and ditches are built fast, prevention of seepage hangs the ditch construction, soil erosion and water loss are administered and are prevent wind the firm sand, rescue and relief disaster road and mine gallery and urban construction facility maintenance, oil and gas pipeline connects and submarine pipeline, submarine optical cable and cable protection etc..

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The cement blanket of example 1, as shown in fig. 1, includes a bottom layer 1, a pile layer 2 disposed on the bottom layer 1, and a permeable top layer (not shown in the figure), the top layer is compounded on the pile layer 2, the pile layer 2 is composed of a plurality of pile tows 3, the plurality of pile tows 3 are arranged on the bottom layer 1 at equal intervals, a distance between two adjacent pile tows 3 is 15 μm, and the pile layer 2 is filled with a cement-based composite material (not shown in the figure).

In example 1, the bottom layer 1 is a waterproof film, and the cement-based composite material is cement-based dry powder filled into the wool layer 2 at the construction site. After construction, the cement-based dry powder is watered to be solidified and molded.

The cement blanket of embodiment 2 is different from embodiment 1 in that in embodiment 2, the pile yarn layer 2 is the pile yarn layer 2 formed by blending the glass fiber 4 and the polyester fiber 5, the pile yarn layer 2 is arranged on one side of the bottom layer 1 through a drawing process, the bottom layer 1 is a water permeable membrane formed by hot pressing the glass fiber 4 and the polyester fiber 5, the cement-based composite material is cement paste sprayed into the pile yarn layer 2 at a construction site, and the cement paste is cured and molded after being dried.

In example 2, the diameters of the glass fibers 4 and the polyester fibers 5 constituting the ground layer 1 and the pile yarn layer 2 were all 7D, and the weight of the cement blanket was 8 kg/m²The thickness of the bottom layer 11 is 2mm, and the thickness of the floss layer 22 is 5 mm.

The cement blanket is convenient to construct, environment-friendly and good in durability, and can be applied to slope protection and road shoulder laying along the railway and the highway, rapid construction of various ditches, seepage-proofing suspended ditch construction, water and soil loss treatment, wind prevention and sand fixation, rescue and relief roads, mine tunnels, urban construction facility maintenance, petroleum and natural gas pipeline joints, submarine pipelines, submarine optical cables, cable protection and the like.
