Problems solved by technology
In this patent, the drainage board is used for the drainage board. The cross-section of the drainage board is wavy, and it is difficult to withstand large pressure, so it will weaken the lining to prevent deformation or collapse of the surrounding rock, resulting in a decrease in the strength of the lining.

Embodiment Construction
[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0020] Such as figure 1 As shown, a lining support device with an improved structure, the lining support device with an improved structure includes a peripheral protective layer 11, a main waterproof layer 21 and a prefabricated arch layer 31 arranged in sequence, the peripheral protective layer 11, the main waterproof layer 21 and The cross-sections of the prefabricated arch layers 31 are circular and concentric. The outer protective layer 11 is formed by pouring concrete. The inner surface of the outer protective layer 11 has a number of water diversion grooves 12 arranged in the circumferential direction. The main waterproof layer 21 is fixed on the outer peripheral surface of the prefabricated arch layer 31. The main w...

The invention provides a lining supporting device, and belongs to the technical field of tunnel construction. The lining supporting device solves the technical problem that an existing lining supporting device cannot meet the requirements for high lining strength and good water leakage prevention performance at the same time. The lining supporting device comprises a peripheral protective layer, a main waterproof layer and a prefabricated arch leaf layer in sequence, wherein a plurality of water diversion grooves which are formed in the peripheral direction are formed in the inner side face of the peripheral protective layer, the main waterproof layer is fixed on the peripheral surface of the prefabricated arch leaf layer, the prefabricated arch leaf layer comprises a plurality of prefabricated slabs, fixing pipes are further fixed on the prefabricated slabs, each prefabricated slab comprises a slab body, a first abutting portion and a second abutting portion, each first abutting portion and each second abutting portion are arranged at the two ends of each slab body respectively, the first abutting portions and the second abutting portions of adjacent prefabricated slabs are fixed in a staggered mode, rubber pads are arranged between the first abutting portions and the second abutting portions, and the first abutting portions and the second abutting portions are fixed through rivets. The lining supporting device has the advantages of being high in strength and good in water leakage prevention performance.
Description
technical field [0001] The invention belongs to the field of tunnel construction and relates to a lining support device with an improved structure. Background technique [0002] my country has a coastline of nearly 20,000 kilometers, dotted with islands and bays. In the future, with the further development of the national economy and the further improvement of people's living standards and quality, the demand for cross-sea transportation will increase day by day. It has been a long-standing dream of people of all countries to connect islands and even continents far away from the mainland by means of bridges or tunnels to facilitate people's travel and promote regional economic development. With the development of modern survey technology, building material technology and construction technology, these dreams have been gradually realized in many places. When constructing a road or railway passage across the sea, you can choose between the bridge scheme and the tunnel scheme....
