The concrete column and crossbeam, which are provided with, to be used to insert the butting member that precast concrete blocks the docking dovetail groove in water stake, institute
State butting member to insert respectively in the docking dovetail groove that a pair of precast concretes block water stake, the top surface of crossbeam is inserted provided with one group of bridge floor
Access slot；The base end face touches with riverbed bottom connection, and the base passes through the swallow on one group of butting member and concrete column
Stern notch is docked so as to be connected on concrete column, and the gate is above the base；The prefabricated bridge bottom is set
There are two groups of inserting columns, two groups of inserting columns are inserted respectively into one group of bridge floor inserting groove that precast concrete blocks water stake and crossbeam top surface
It is interior；After check dam installation, affixed sealing is carried out by concrete spraying.
Operation principle：When building check dam, water stake first is blocked pouring a pair of precast concretes in the both sides in river, a pair
Precast concrete blocks water stake and gos deep into riverbed underground 5-20 rice, while a pair of frids are poured into a pair of precast concretes respectively and block water
In docking dovetail groove in stake interface, after pouring sizing, conserve 14-20 days, found concrete using after Large-scale Hoisting equipment
The butting member of post side is inserted into docking dovetail groove, then the butting member on base is inserted into pair on concrete column
Connect in dovetail groove, and on base, gate is set up between concrete column, finally a pair of butting members of crossbeam are inserted respectively
Precast concrete is blocked in the docking dovetail groove of water stake, and the bottom surface of crossbeam is fitted on the top surface of a pair of concrete columns, crossbeam
It is concordant that top surface with precast concrete blocks water stake；After each part abutting joint, one group of inserting column on prefabricated bridge is inserted respectively
In one group of bridge floor inserting groove for entering to precast concrete to block water stake and crossbeam top surface, carried out finally by concrete spraying affixed close
Envelope, after entirety conserves 15-20 days, you can install the related facility of water-power plant.
Beneficial effect：The utility model provides a kind of check dam for Hydraulic and Hydro-Power Engineering, reasonable in design, will block
Dam is divided into several big modules and assembled, therefore is not in due to the non-coagulation forming of inner concrete and the feelings that are flushed away when collaborating
Condition；The interflow of check dam is completed using each module self gravitation, substantially reduces the interflow difficulty of check dam, and and possess logical
Row function, there is good application and popularization value.
