Buttress-type steel structure dam

Abstract

The invention discloses a buttress-type steel structure dam. The buttress-type steel structure dam comprises a water retaining plate, a foundation and a support truss, wherein an anchoring piece is arranged in the foundation; the anchoring piece is fixedly connected with the bottom part of the truss on the upper part; the truss comprises a certain number of master rods which are approximately vertical to the water retaining plate, vice rods which are vertical to the master rods, and inclined rods which are connected diagonally, wherein the master rods are long rods; the vice rods are short rods; the two ends of each vice rod is connected with each of the master rods; the distance between adjacent master rods is L; the distance L becomes larger gradually from the lower part to the upper part of the water retaining plate; the two ends of the truss are provided with side piers; and the shape of the side piers are matched with the shape of the cross section of the steel structure dam. The supporting capacity of the truss of the buttress-type steel structure dam is high; the truss structural design is reasonable; the two ends of the truss of the steel structure dam of the invention are provided with the side piers; and other water conservancy facilities such as an escape gate, a ship passing gate or the like can be arranged on the side piers, so that the steel structure dam also has other functions besides the functions of retaining and storing water.

Description

[0001] technical field [0002] The invention relates to the technical field of water conservancy engineering, in particular to a pier-type steel structure dam. Background technique [0003] At present, the water retaining structures in water conservancy and hydropower projects mainly include gravity dams, earth-rock dams and arch dams. The water conservancy projects of these three types of dams all have the characteristics of large investment, long construction period, difficult construction and relatively large impact on the environment. For different building types, the following specific analysis of the existing deficiencies. [0004] The working characteristic of the gravity dam is to rely on the anti-sliding force generated by the dam body's own weight to meet the stability requirements of the dam body, and rely on the compressive stress generated by the dam body's own weight to offset the tensile stress caused by the water pressure. This determines that the grav...
