Problems solved by technology

When using existing building composite materials such as concrete and masonry rubble, temporary mixing is required. Manual mixing will make the material mixed unevenly, which will generate a lot of dust. The labor intensity of the workers is relatively high, and the working environment is poor. low efficiency
[0003] In particular, in the existing soft rock roadway support technology, the joints and fissures at the bottom of the soft rock are relatively developed, the stability is poor, the f value is 1.5-4, and there are serious alteration phenomena, and the roadway is extremely unstable during the excavation process

Embodiment 1

[0039] Such as figure 1 As shown, it includes an upper fabric 1-1, a lower fabric 1-3, and a sponge cement layer 1-2 and a wire mesh sandwiched between the upper fabric 1-1 and the lower fabric 1-3, and the upper fabric 1-1 And the outer contour size of the lower fabric 1-3 is greater than the size of the sponge cement layer 1-2 and the wire mesh, the upper fabric 1-1, the sponge cement layer 1-2, the wire mesh and the lower fabric 1 -3 stitched together by fiber thread;

[0040] The wire mesh at least includes a lower wire mesh 1-4 arranged between the lower fabric 1-3 and the sponge cement layer 1-2;

[0041] Both sides of the lower wire mesh 1-4 are provided with handles 1-41.

[0042] The sponge cement layer 1-2 includes a sponge and the cement or the mixture of cement, quick-setting agent and sodium silicate filling the gaps of the sponge.

[0043] The density of the sponge is less than 18kg / m 3 .

Embodiment 2

[0045] Such as figure 2 As shown, the difference from Embodiment 1 is that: it also includes an upper layer wire mesh 1-5 arranged between the upper layer fabric 1-1 and the sponge cement layer 1-2.

[0046] The present invention also relates to a kind of preparation method of sponge cement blanket, comprises following embodiment:

Embodiment 3

[0048] Such as figure 1 , image 3 and Figure 4 As shown, the steps are as follows:

[0049] Step 1. Prepare materials, prepare upper fabric 1-1, sponge and lower fabric 1-3, the size of the lower fabric 1-3 and the upper fabric 1-1 are the same, the size of the sponge cement layer 1-2 Smaller than the size of the upper and lower fabrics, the density of the sponge is less than 18kg / m 3 ;

[0050]Step 2. Prepare the sponge cement layer 1-2, place the sponge on the vibrating platform 2, and the bottom of the vibrating platform 2 is provided with a cement recovery device (not shown in the figure), including the vibrating platform supporting leg 2-1, installed on the vibrating platform 2. The surrounding frame 2-3 on the support leg 2-1 of the vibration platform and the vibration motor 2-2 installed on the side of the surrounding frame 2-3, the lower floor wire mesh is provided in the described surrounding frame, and the surrounding frame The frame is provided with a groove,...

Abstract

The invention relates to a sponge cement blanket, which comprises an upper-layer fabric, a lower-layer fabric, and a sponge cement layer and a metal wire mesh clamped between the upper-layer fabric and the lower-layer fabric. The sizes of outer contours of the upper-layer fabric and the lower-layer fabric are larger than the sizes of the sponge cement layer and the metal wire mesh; the upper-layerfabric, the sponge cement layer, the metal wire mesh and the lower-layer fabric are sewn together through fiber silk yarns; the metal wire mesh at least comprises a lower-layer metal wire mesh arranged between the lower-layer fabric and the sponge cement layer; the sponge cement layer comprises sponge and cement filling gaps of the sponge, or a mixture of the cement, an accelerator and sodium silicate. The sponge cement blanket is convenient to use, low-cost and high in strength. The invention also relates to a preparation method of the sponge cement blanket, which comprises the steps of firstly preparing materials, then preparing the sponge cement layer on a vibration platform, and finally sewing on a sewing platform, so that the sponge cement blanket is simple and fast to prepare.

Description

technical field [0001] The invention relates to a sponge cement blanket and a preparation method thereof. Background technique [0002] With the development of social economy, the construction engineering industry and civil engineering industry have also developed rapidly, and the quality requirements for construction are getting higher and higher. Ditch, slope protection, mining area, etc. When using existing building composite materials such as concrete and masonry rubble, temporary mixing is required. Manual mixing will make the material mixed unevenly, which will generate a lot of dust. The labor intensity of the workers is relatively high, and the working environment is poor. low efficiency. [0003] In particular, in the existing soft rock roadway support technology, the joints and fissures at the bottom of the soft rock are relatively developed, the stability is poor, the f value is 1.5-4, and there are serious alteration phenomena, and the roadway is extremely unst...
