Abstract
The utility model discloses a mixed earth dam and gravity dam arrangement structure which comprises homogeneous earth dams and a gravity dam, wherein the homogeneous earth dams are arranged on soil matrixes on both shores; the gravity dam is arranged between the two homogeneous earth dams and on a riverbed rock foundation; the left side and the right side of the gravity dam are connected with the homogeneous earth dams on the corresponding sides through concrete gravity retaining walls; the gravity dam is composed of an overflow dam section, a five-hole flood discharge dam section with a breast wall gate, and a desilting underport dam section from left to right; the gate holes of the flood discharge dam section are separated by middle piers; the left side and the right side of the flood discharge dam section are connected with the overflow dam section and the desilting underport dam section through abutment piers; a stilling basin is arranged on the downstream side of the gravity dam; a water diversion opening is formed in the upper part of the desilting underport dam section. According to the utility model, the functions of dam overflow, flood discharge, desilting and the like are arranged on the riverbed middle rock foundation, and the homogeneous earth dams capable of retaining water are arranged on soil matrixes on both shores, so that earth dam slopes on both shores are prevented from being eroded on the premise of meeting energy dissipations of overflow, flood discharge, desilting and the like.
Description
Technical field
The utility model relates to the check dam in water conservancy construction, especially relates to the arrangement that earth dam+gravity dam mixes dam type.
Background technology
In dam work hinge arrangement, usually to select dam type in conjunction with local geological conditions.Conventionally, the riverbed of a dam site is all consistent with the basis of two sides, selects gravity dam when both dam foundation is all rock, selects earth dam when dam foundation is all loess.But, the basis, two sides that runs into dam site is loess and basis, riverbed is under the geological conditions of rock, if when dam is all made concrete gravity dam, can cause two sides dam foundation excavation amount huge, and do not meet the excavation requirement of concrete gravity dam specification to the dam foundation, the concrete gravity dam dam foundation must be located on basement rock.
Summary of the invention
The utility model object is to provide a kind of earth dam+gravity dam to mix the arrangement of dam type.
For achieving the above object, the utility model is taked following technical proposals:
Earth dam described in the utility model+gravity dam mixes the arrangement of dam type, comprises the homogeneous earth dam being arranged on the soil matrix of two sides, is arranged on the gravity dam in riverbed rock foundation between described two homogeneous earth dams; The described gravity dam left and right sides is connected with the homogeneous earth dam of respective side by concrete gravity retaining wall respectively; Gravity dam is made up of Overflow Section, the flood discharge monolith of five pore area breastwork gates, bottom hole for sand flushing monolith from left to right; Between the lock hole of described flood discharge monolith, adopt Zhong Dun interval, the left and right sides of flood discharge monolith is connected with Overflow Section and bottom hole for sand flushing monolith by abutment pier respectively; Be provided with absorption basin in gravity dam downstream; Be provided with irrigating gate on bottom hole for sand flushing monolith top.
The utility model advantage is to take the functions such as dam overflow, flood discharge, sand discharge are arranged in the rock foundation of middle part, riverbed, the homogeneous earth dam of water retaining function is arranged in to the arrangement form on the soil matrix of two sides, reaches homogeneous earth dam and concrete gravity dam are effectively combined.Therefore,, meeting under the prerequisite of the energy dissipatings such as overflow, flood discharge, sand discharge, avoided washing away two sides soil property dam slope.
