Abstract

The invention discloses a water diversion pipe structure in a local material dam and a construction method, wherein the water diversion pipe structure comprises a lining structure, a water diversion pipe, a bracket and a deformation space, the lining structure comprises a bottom plate, straight segments and circular segments, the straight segments are symmetrically fixed on the two sides of the bottom plate, the circular segments are arranged on the top portions of the straight segments, the water diversion pipe is arranged in the lining structure, and is fixed through the bracket, the bracket comprises support blocks and support feet, and the deformation space is arranged between the lining structure and the water diversion pipe. The construction method comprises the steps: 1 the size of the lining structure is determined; 2 structure materials are selected; 3 the lining structure is made; and 4 the water diversion pipe and the bracket are mounted. The water diversion pipe structure in the local material dam and the construction method excellently solve the integration problem between deformation characteristics of local material dams and the water diversion pipe, greatly reduces engineering quantity of a water diversion system, saves project investment of a water conservancy and hydropower water diversion system, and reduces construction period of the water conservancy and hydropower water diversion system.

Description

technical field [0001] The invention relates to a water diversion pipe structure and a construction method in a local material dam, and belongs to the technical field of water diversion in hydropower and water conservancy projects. Background technique [0002] According to the existing technical level of local material dams, and considering the long-term (more than 2 years) continuous uneven settlement characteristics of local material dams, in order to ensure the safety of local material dams, local material dams cannot be arranged in conjunction with water diversion systems. Usually, water diversion The system is arranged on the shore in the form of tunnels or channels, avoiding mixed arrangements with local material dams and mutual influence. However, this layout method increases the engineering quantity of the water diversion power generation system to a certain extent, prolongs the construction period of the water diversion power generation system, and increases the in...
