Problems solved by technology

[0005] The purpose of the present invention is to provide a method for building underground reservoirs to effectively solve the problems of limited land resources, poor conditions for building reservoirs, and difficult policy handling for building surface reservoirs in island areas. At the same time, the problem of water shortage in island areas can be solved by building underground reservoirs. It also solves the problem that the island is vulnerable to flooding and waterlogging

Embodiment Construction

[0017] The present invention will be further described below in conjunction with embodiment.

[0018] The invention relates to a construction method of an island underground reservoir, comprising:

[0019] a. Carry out geological exploration, determine the location of the main water storage tunnel, excavate the main water storage tunnel, excavate the main tunnel to the design depth, the design depth is 12m wide, 15m high, the tunnel roof elevation is 3m, and the national regulation is 85 elevation;

[0020] b. Carry out geological exploration, determine the location of the branch tunnel, and excavate the branch tunnel to the design depth. The design depth is 12m wide, 15m high, and the tunnel roof elevation is 3m;

[0021] c. Carry out geological exploration and excavate multiple surface water inlet wells around the periphery of the main tunnel and branch tunnels, so that the surface water inlet wells can meet the water sources of the main tunnel and branch tunnels;

Abstract

The invention relates to a novel construction method for an underground reservoir of a sea island. The construction method comprises the following steps: a, carrying out geological prospecting to determine the position of an impounding main tunnel, and excavating the impounding main tunnel to a designed depth which is 12 m wide and 15 m high, wherein the crest level of the tunnel is 3 m; and b, carrying out geological prospecting to determine the position of a branch tunnel, and excavating the branch tunnel to a designed depth which is 12 m wide and 15 m high, wherein the crest level of the tunnel is 3 m.

Description

technical field [0001] The invention relates to a method for building a reservoir, in particular to a method for building an underground reservoir, which belongs to the field of water conservancy construction. Background technique [0002] Reservoirs refer to artificial lakes formed by building barrages at the narrow mouths of ravines or rivers. After the reservoir is completed, it can play the roles of flood control, water storage for irrigation, water supply and fish farming. The islands in the Jiangnan area of ​​China all have the problem of water shortage and water abundance. The lack of water is due to engineering water shortage. The conditions for building reservoirs in the island area are poor, and the lack of effective water storage projects results in a small amount of water available for the island; the water is mostly due to the annual rainy season and typhoon season. Drainage, causing waterlogging, although many drainage pumping stations have been built at the ...
