Example 1

Referring to fig. 1, the present embodiment provides a composite cement blanket by needle punching, which includes a plurality of single bodies 1, wherein the single bodies 1 are integrally connected, and a breaking assisting line 2 is disposed between any two single bodies 1 for separating the two single bodies 1.

Cement blankets are commonly used in reservoirs, banks, channels, gutters, highways, railways, and the like. The cement blanket is the soft cloth of monoblock before meeting water and taking place hydration reaction, during the use, often need carry out various tailorres to the cement blanket to adapt to different occasions. However, in the construction process, the constructors often need to cut by other tools, and the cut shapes are not regular and regular, the sections are not flat, and the overall attractiveness is affected. The utility model discloses in, a plurality of monomers 1 constitute monoblock cement blanket, set up between two arbitrary adjacent monomers 1 and help the broken string 2, through this help the broken string 2, needn't tear monolithic monomer 1 with the help of the foreign object, and 1 appearances of monomer torn are pleasing to the eye, and the section is level and smooth, and the user is also labour saving and time saving more when the operation.

In some embodiments, the shape of the single body 1 may be circular, oval or polygonal, and the same cement blanket may be formed by multiple single bodies 1 with different shapes, so as to meet the construction requirement. The shape of the single body 1 is rectangular, as a rectangular cement blanket is a more classical shape, which is satisfactory for most applications. The adjacent rectangular single bodies 1 are intermittently connected (as shown in figure 1), and the 'broken' positions of the single bodies 1 at the left side and the right side are sealed, so that concrete, cement powder and the like at the inner sides are prevented from leaking; the connection part can be communicated with the inside, so that when a user pours water on the cement blanket, the concrete, cement powder and the like in the inside can be contacted with the water to generate hydration reaction and can be hardened into a whole without being influenced by the auxiliary breaking line 2. If the constructor does not need the whole cement blanket during construction, before the cement blanket is hardened, the cement blanket with the corresponding size is torn off along the auxiliary breaking line 2. The size of each single body 1 can be customized according to the application, or the common sizes can be set, and the length can be 1m, 5m, 10m, 20m and the like.

Example 2

Compared to the above embodiments, a better connection method is proposed for the connection of the adjacent monomers 1 in this embodiment.

In the above embodiments, there are some disadvantages, one is that the cement blanket is thick, the number of layers is large, the "break-and-continue" ratio of the broken line is not easy to be grasped, and if the "break" part is large, the single bodies 1 are easy to crack; if the continuous (i.e. connected) part is more, the tearing is not easy. Secondly, the remaining part after tearing probably will be idle for a long time, but the cross section department of tearing the department will expose partial middle part fiber framework 132 layer and concrete powder, and concrete powder still leaks out from the fracture department easily, is not convenient for deposit, easily wets and causes the waste.

In the present embodiment, the periphery of each single body 1 is sealed, a transition section 3 is also arranged between adjacent single bodies 1, and the breaking-assisting line 2 is positioned on the transition section 3 (as shown in fig. 2). Thus, when the user tears off the single-piece single body 1, the edges of the torn single body 1 and the single-piece single bodies 1 adjacent to the single body 1 are still closed, and the torn part does not expose the fiber skeleton layer and the concrete powder inside the single body 1. Can prevent that the concrete powder from revealing from the section mouth, avoid extravagant, easily deposit, it can be cleaner to use, and confined border can prevent that monomer 1 from weing, even if deposit for a long time can not influence the quality of cement blanket yet. In addition, the transition section 3 can be made of a material with low toughness to form a single layer, and compared with the method for punching intermittent holes on a multi-layer cement blanket, the intermittent holes on each layer are ensured to correspond to each other, obviously, the operation is easier, the using effect is better, and the cost is lower when the intermittent holes are punched on the single-layer transition section 3.

Example 3

Referring to fig. 3, in some embodiments of the present invention, any of the single bodies 1 includes a top fabric 11 and a bottom fabric 12 connected to each other, and a filling layer 13 is disposed between the top fabric 11 and the bottom fabric 12.

In this embodiment, the internal structural layers of all the single bodies 1 are almost the same, are layered structures, and may be composed of three layers, namely, a top fabric 11, a filling layer 13, and a bottom fabric 12 from top to bottom. The main performance is by the inside filler of outside fabrics parcel, and the filler is solidifiable combined material 131, like concrete powder etc. meets inside concrete powder of water and can partially spill over, and the fabric outside wrapping together solidifies into a whole, hardens into concrete layer to firmly attach above the ramming soil layer.

Referring to fig. 3, in some embodiments of the present invention, the filling layer 13 is filled with a curable composite material 131.

In the present embodiment, the filling layer 13 is mainly filled with a curable composite material 131, such as cement powder, concrete powder, or the like. The cement carpet can be quickly solidified by hydration reaction when meeting water, so that the whole cement carpet becomes hard. Convenient and fast use, no need of on-site blending and manufacturing, time saving and labor saving.

Referring to fig. 3, in some embodiments of the present invention, a fiber skeleton 132 is further disposed in the filling layer 13, and the curable composite material 131 is filled in the gaps of the fiber skeleton 132.

In this embodiment, the fiber skeleton 132 is further filled in the filling layer 13, the fiber skeleton 132 is internally provided with a dense mesh structure with intricate structure, and the cement powder or the filling concrete powder is filled in the gaps of the dense mesh, so that the powder in the dense mesh structure can be uniformly distributed in all places of the cement blanket, and even if the cement blanket is arbitrarily cut, the dense mesh structure with intricate structure can effectively prevent the powder in the dense mesh structure from falling from the fracture surface. The fiber framework 132 is mainly woven from polyethylene and polypropylene, and when the cement is solidified, the fiber threads can enhance the toughness of the solidified cement blanket and prevent cracking. And the addition of the fiber framework 132 can save more cement raw materials, reduce the cost and reduce the weight.

As a carrier capable of uniformly distributing concrete, the middle fiber framework 132 also has extremely strong water absorption performance, and absorbed water just generates hydration reaction with the mixed mud powder in the gaps, so that the cement blanket can be hardened as soon as possible. Other materials such as sponge and filling cotton can achieve the same effect, and the cost, the occasion, the cost performance and the like of the material need to be considered when the material is used specifically.

Example 4

Referring to fig. 3, in some embodiments of the present invention, a waterproof layer 14 connected to the bottom fabric 12 is further disposed between the filling layer 13 and the bottom fabric 12.

In this embodiment, besides the top fabric 11, the bottom fabric 12 and the filling layer 13 in the above embodiments, a waterproof layer 14 may be further disposed between the filling layer 13 and the bottom fabric 12, and the top fabric 11, the filling layer 13, the waterproof layer 14 and the bottom fabric 12 are sequentially arranged from top to bottom. The filling layer 13 is filled with a curable composite material 131, in this embodiment, cement powder, concrete powder, etc., and the upper and lower layers of fabrics sandwich the filling layer, and the top fabric 11 needs to be a water-permeable textile. Before use, the cement blanket is laid at the target area position, then a proper amount of water is sprayed on the cement blanket, the water penetrates downwards through the pores of the top layer fabric 11, the curable composite material 131 in the filling layer 13 undergoes hydration reaction when meeting water and is cured quickly, and the texture of the curable composite material becomes hard at one stroke. In addition, the waterproof layer 14 on the bottom fabric 12 can effectively prevent water from continuously permeating downwards, so that water is locked in the filling layer 13, water loss is avoided, more water is in contact with cement powder or concrete powder, and the reaction time is shortened.

In some embodiments of the present invention, the waterproof layer 14 is bonded or sewn to the bottom fabric 12, and the bottom fabric 12 is sewn to the top fabric 11.

In this embodiment, the waterproof layer 14 and the bottom fabric 12 are bonded or sewn, but since the waterproof layer 14 is thin and is close to the bottom fabric 12, the waterproof layer 14 can be bonded to the inner side of the bottom fabric 12, then the bottom fabric 12 and the waterproof layer 14 as a whole are sandwiched with the top fabric 11 to sandwich the filling layer 13, and finally the four-layer structure is connected together by the fiber yarns (or they can be tightly connected by pressing). Another way is to press the four-layer structure together first and then fix it further with fibre threads. By adopting the two connection modes, the connection is firm, the cost is low and the operation is simple. Of course, a waterproof silicone coating may also be applied to the inner side of the base fabric 12 as the waterproof layer 14.

Example 5

In some embodiments of the present invention, the top fabric 11 comprises a single-layer or multi-layer nonwoven fabric.

In this embodiment, the top fabric 11 is made of a nonwoven fabric, and may be one or more layers. Nonwoven fabrics, also known as nonwovens, are composed of oriented or random fibers.

In addition, in terms of environmental protection, since most of the nonwoven fabrics used are polypropylene and the plastic bag is polyethylene, the two materials have similar names but are far from each other in terms of chemical structure. The chemical molecular structure of polyethylene has quite strong stability and is extremely difficult to degrade, so that the plastic bag can be decomposed in 300 years; the chemical structure of polypropylene is not firm, molecular chains can be easily broken, so that the polypropylene can be effectively degraded, and can enter the next environmental cycle in a non-toxic form, and the pollution degree of the discarded polypropylene to the environment is only 10% of that of a plastic bag, so that the polypropylene has little influence on the environment and is reversible. The concrete number of layers in the cement blanket may depend on the application, and is not particularly limited in this embodiment.

In some embodiments of the present invention, the base fabric 12 comprises a single layer or a plurality of layers of woven or knitted fabric.

In this embodiment, the base fabric 12 is made of an organic woven fabric (geotextile), and may be one or more layers. The geotextile has multiple functions of seepage prevention, reverse filtration, drainage, isolation, reinforcement, protection, sealing and the like, and has the advantages of low investment, simple construction process, short construction period, good seepage prevention effect, high effective utilization coefficient of channels and the like compared with the seepage prevention effect of the conventional stone building and concrete material. In addition, the material has good corrosion resistance, is not easy to be damaged by microorganisms, worms and the like, and is very convenient to transport, lay and construct due to light and flexible material. Besides the above beneficial effects, the bottom fabric 12 can also reinforce the solidified cement blanket, and has the functions of plane isolation and protection.

In some embodiments of the present invention, the waterproof layer 14 is made of silica gel.

In this embodiment, the waterproof layer 14 is made of silica gel, and has wide temperature adaptation, good sealing performance and insulation performance, high and low temperature resistance, and less interference from the external environment, so that it is an ideal waterproof and sealing material, and is non-toxic, odorless, less in influence on the surrounding environment, environment-friendly and safe. This silica gel waterproof layer 14 can prevent effectively that water from continuing to permeate downwards, locks moisture at filling layer 13, avoids moisture to run off, makes more water and cement powder or concrete powder contact, reduces the time of reaction, also avoids unnecessary moisture to dip the rammer layer of below simultaneously, influences the result of use of cement blanket.

Example 6

Referring to fig. 3, in some embodiments of the present invention, the thickness of the filling layer 13 is 1/3-9/10 of the total thickness of the single body 1.

In the present embodiment, the cement powder in the filling layer 13 is a core material for realizing the hardening of the cement blanket from soft, and the thickness of the filling layer 13 plays a decisive role in achieving the purpose, and a smaller proportion of the filling layer 13 in the whole thickness (in general) means that the less cement powder is filled, and the larger proportion of the filling layer 13 in the whole thickness is, the more cement powder is filled. The user can customize and select the cement blanket with the corresponding thickness according to the actual condition. In this embodiment, the thickness of the filling layer 13 is preferably about 3/4 to 5/7 of the entire thickness of the single body 1.
