Problems solved by technology

In order to prevent the surrounding rock from collapsing due to deformation, sprayed concrete and steel reinforcement measures are usually adopted. Once the rock mass deforms, the force will be transmitted to the cave wall, increasing the risk of cave wall damage. A slight damage may cause huge losses and dangerous, and the price of steel bars and other materials is relatively high, and the large-scale use of steel support will cost more

Embodiment 1

[0037] see Figure 1-6 , a kind of sub-compartment lining pressure relief support structure with multiple fillings, which includes complete surrounding rocks 1, and surrounding rock plastic zones 2 are mixed between the complete surrounding rocks 1, and the complete surrounding rocks 1 and surrounding rocks The inner wall of the plastic zone 2 is provided with two linings 12, and a gap is provided between the two; inside the gap, a debris bin 4 is arranged on the inner wall of the complete surrounding rock 1 and the plastic zone 2 of the surrounding rock, A liquid debris layer 3 is arranged inside the debris bin body 4 , and a ceramsite bin body 10 and a water-filled carcass 5 are arranged in the gap between the debris bin body 4 and the second liner 12 . By adopting the above-mentioned lining pressure relief support structure, targeted support can be carried out for specific areas, and the fluid debris layer 3 can independently provide specified support reaction forces to the...

Embodiment 2

[0052] The construction method of the sub-compartment lining pressure relief support structure of any one of the various fillers, it comprises the following steps:

[0053] Step1: Material preparation: Prepare pressure sensor 13, automatic pressure relief valve 6, pressure gauge 7, rubber carcass 17, steel arch frame, waste fluid debris, ceramsite and carcass fluid 18;

[0054] Step2: Make filling package: put the selected waste liquid debris into the flexible package bag 15, and wrap the geotextile bag 16 outside to complete the debris bin 4; wrap a layer of carcass protection on the water-filled carcass 5 Layer 9, fill the carcass fluid 18 from the carcass fluid input port, and ensure good airtightness; after connecting the water-filled carcass 5 with the automatic pressure relief valve 6 and the drain pipe 8, set the automatic pressure relief Threshold of the valve 6, water is injected into the rubber carcass 17 to complete the water-filled carcass; the selected ceramsite i...

Abstract

The invention provides a split-cabin lining pressure-relief support structure with multiple fillers, and a construction method. The split-cabin lining pressure-relief support structure comprises an intact surrounding rock interspersed with a surrounding rock plastic zone. Two linings are arranged on the inner side walls of the intact surrounding rock and the surrounding rock plastic zone, and a gap is formed between the two linings; a clast cabin is arranged on the inner side wall, close to the intact surrounding rock and the surrounding rock plastic zone, in the gap; a liquid clast layer is arranged in the clast cabin, and a ceramsite cabin and a water-filling jig are arranged in gaps between the clast cabin and the two linings. The split-cabin lining pressure-relief support structure andthe construction method have the advantages that the surrounding rock is supported by the cabins with the different fillers in a stacking mode of up-down, left-right, front-back, etc. according to stress conditions and rock deformation of a tunnel at different positions, pressure relief is realized through the fluidity of the fillers in the cabins in case of the rock deformation, and accordingly,the advantages of different materials are combined and utilized maximally.

Description

technical field [0001] The invention is mainly aimed at the lining support and deformation pressure relief of the tunnel and the construction method, realizes the safe and economical pressure relief according to the stress conditions at different positions of the tunnel and the deformation of the rock mass while supporting the tunnel, and is applicable to various tunnels and Channels and other structures to be supported. Background technique [0002] The traditional lining is a permanent support structure built with reinforced concrete and other materials around the tunnel body. In order to prevent the surrounding rock from collapsing due to deformation, sprayed concrete and steel reinforcement measures are usually adopted. Once the rock mass deforms, the force will be transmitted to the cave wall, increasing the risk of cave wall damage. A slight damage may cause huge losses and dangerous, and the price of materials such as steel bars is relatively high, and it will cost m...
