Problems solved by technology

In the existing scientific research, the tunnel lining is often simplified as an equivalent permeable layer, but it is difficult to realize it in experiments, so most of the research in this area focuses on analytical research and numerical research
Without the support of test data, the success of theoretical research will be greatly reduced. Therefore, in order to overcome the shortcomings of existing research methods and supplement the experimental data in related research fields, the present invention has developed a test mold for lining pouring of partially permeable tunnels.

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0022] like figure 1 As shown, the present embodiment provides a trial mold for lining of a partially infiltrated tunnel, which includes four parts: a trial mold base 1 , a trial mold outer cover, a trial mold liner and a separation piece 6 .

[0023] like figure 2 As shown, the test mold base 1 is a circular iron plate with 4 concentric circular grooves. In this example, the diameter of the circular steel plate is 250mm, and the thickness is 20mm. The inner and outer diameters of the first groove are respectively 200mm, 220mm, the second groove is 160m, 180mm, the third groove is 120mm, 140mm, the fourth groove is 80mm, 100mm.

[0024] The tryout cover includes a bottom cover, a standard cover and a top cover.

[0025] like image 3 As shown, the bottom cover is two consistent 180° curved steel plates A2-1, the inner and outer diameters ...

Abstract

The invention discloses a local seepage tunnel lining pouring test mold. The mold comprises a rest mold base, a test mold outer cover, a test mold inner container and a separation piece. The test moldbase is a circular iron plate caved with multiple concentric ring-shaped grooves. The test mold outer cover comprises a bottom layer outer cover, a standard layer outer cover and a top layer outer cover. The test mold inner container is a long hollow cylinder. The separation pieces are four long-strip-shaped thin iron sheets. By assembling the test mold outer cover, the test mold outer cover andthe test mold inner container and the separation pieces are arranged on the test mold base to form four independent fan-shaped pouring spaces. Accordingly, by adjusting the sizes of the test mold outer cover and test mold inner container, local seepage hollow cylinder mortar test pieces with different specifications are poured. Effective test data support can be provided for research of underwatertunnel water-earth pressure, and help is provided for theoretical analysis.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to a pouring test mold for lining of partially infiltrated tunnels, which can be used for pouring linings of partially infiltrated tunnels with different thicknesses and heights of test pieces. Background technique [0002] Some scholars pointed out that in the next ten years, my country will build 20,000 kilometers of various types of tunnels, including road tunnels, high-speed rail tunnels, water conservancy tunnels, and urban subways. In order to reduce the water pressure on the tunnel, seepage channels are often reserved, coupled with the assembly joints of the lining tunnel and the lining cracks caused by long-term operation, all of which make the tunnel lining have a certain degree of permeability, but the number of cracks in different parts of the tunnel lining is different. , which leads to different permeability in various parts of the tunnel. Existing scientific resea...
