Embodiment Construction
[0041] Inventor Li Lanjing works in the Gezhouba Hydropower Survey and Design Institute, and has certain favorable conditions for implementing the present invention. The inventor hopes to have the opportunity to cooperate with the construction unit and all units and individuals that have the opportunity to cooperate, and to jointly make the following points :
[0042] 1. Pay attention to methods and work conscientiously: Applying the present invention to "Building a Reservoir in the Blind Valley" will not only make the "replenishment" method technology to build a reservoir on the complex karst stratum, a prospect of "the willow will be dark and the flowers will be bright" may appear, and it will be consistent with "hiding, intercepting The combination of the two methods and comprehensive application, in the karst arid mountainous area, in its deep valleys or terraces at all levels, can select some "blind valleys" or "similar blind valleys" according to the natural and geographi...

The invention relates to reservoir construction in a blind valley, which means an engineering project for building an artificial reservoir with high circumference and low middle part in the blind valley by using the topography of the blind valley and through the peculiar water channel of the blind valley so as to be short for the reservoir construction in the blind valley. The reservoir construction in the blind valley is applied to water resources utilization in water shortage limestone mountain regions and carbonate bed stratum regions, which belongs to the technical field of engineering construction. The success of basic leaking stoppage and anti-leakage techniques in the reservoir construction is not recorded abroad at present and China is also short of successful experience. The applicant of the invention improves the invention after achieving success on leaking stoppage of small blind reservoirs, seepage prevention and trial assembly of 'a check valve'. The invention mainly adopts the technical core of the design of the check valve and anti-blocking and anti-seepage measures, namely, 1, the installation of one-way anti-leakage facility, the design of the parts thereof and integration into one-way anti-seepage control assembly; 2, observation and monitoring of ground water of karst caves; and 3, silting prevention measure for sand washing, and the like.
Description
Technical field: [0001] Blind Valley Reservoir Construction refers to an engineering project that uses the "Blind Valley" terrain to build an "artificial reservoir". Therefore, it should belong to the field of engineering construction and water conservancy and reservoir engineering technology. "Blind Valley" is a unique valley terrain in the carbonate rock stratum area: the surrounding high and low, like the "eye sockets" of a blind person, so it is called "Blind Valley". Because of the water-soluble nature of carbonate rock formations, the surface landscapes of such rock formations, such as blind valleys, stone forests, karst caves, water outlets / sinkholes, etc., can be seen everywhere, and they are collectively called "karst" or "karst" in geology. "Landform. The "Blind Valley" reservoir area is mostly located in the lower part of the valley area. During the dry season, there is one or several karst caves to drain the surface water. The groundwater level is low, and its lo...
