Abstract
A kind of dam configuration that frost damage prevention destroys, including dam body, it is characterised in that: apply waterproof mortar layer on protecting slope of dam face, be Flexible Sliding layer above waterproof mortar layer, several push plates that disappear being mounted side by side are equipped with above Flexible Sliding layer, the push plate bottom that disappears is placed on limit supporting plate；The utility model is sliding surface using protecting slope of dam slope surface, and the push plate that will disappear is installed on slope surface underwater equal to ice sheet thickness depths, disappear push plate under ice sheet promotion along protecting slope of dam slope surface upward sliding, guide ice sheet to grow up along slope surface；Or ice sheet is made to prolong the push plate plate face growth that disappears, change ice sheet thrust direction, mitigates the pressure to protecting slope of dam face.Since the push plate that disappears increases the contact surface with slope surface, the ice pressure on bank protection slope surface unit area is decreased, so that ice is persistently increased bank protection static pressure and becomes to be gradually reduced dynamic pressure, protects protecting slope of dam not squeezed locally directly by ice sheet and destroys.After ice sheet spring melts, the push plate that disappears falls back to the water surface by self weight, and next winter continues to play a role.
Description
Technical field
The utility model belongs to water conservancy project freeze proof technique field, more particularly, to one kind prevent ice sheet push directly on dykes and dams,
Slope protection generates the dykes and dams that freeze injury destroys.
Background technique
Currently, domestic seasonal frost region reservoir, lake dykes and dams, slope protection works winter, because ice sheet pushes directly on to generate bank protection surface layer grand
Rise, cracking, leakage etc. freeze injuries destroy, belong to high-incidence freeze injury.Traditional method of disposal is simple to carrying out at local eminence, cracking
Maintenance is removed, it is still necessary to repair cofferdam in dykes and dams when large area freeze injury occurs, to dam reinforcement after draining, project amount is huge, water money
Source waste causes environmental pollution, and loss is very big.Even if as excellent as before through the above maintenance dam body and bank protection, after being pushed again by ice sheet
The above freeze injury can occur repeatedly.
Utility model content
The project amount present in the above-mentioned background technique is huge, environmental pollution, serious waste of resources aiming at the problem that, this is practical
Novel purpose is to provide a kind of dam configuration that frost damage prevention destroys, and protects dykes and dams, slope protection not to be squeezed locally directly by ice sheet broken
It is bad.
To achieve the above object, the utility model provides a kind of dam configuration that frost damage prevention destroys, including dam body, feature
It is: applies waterproof mortar layer on protecting slope of dam face, is Flexible Sliding layer above waterproof mortar layer, is equipped with above Flexible Sliding layer
Several push plates that disappear being mounted side by side, the push plate bottom that disappears are placed on limit supporting plate.
The high strength reinforced concrete skewback that push plate is upper-thin-lower-thick that disappears.
The limit supporting plate is L shape, with the anchor connection of protecting slope of dam face.
Pre-buried anchor ring is contacted by drag-line and is fixed at the top of dykes and dams at the top of the push plate that disappears.
The Flexible Sliding layer is polyfluortetraethylene plate, and plate body hard, surface are smooth.
The utility model is sliding surface using protecting slope of dam slope surface, and it is thick equal to ice sheet that the push plate that will disappear is installed on slope surface underwater
Spend depths, disappear push plate under ice sheet promotion along protecting slope of dam slope surface upward sliding, guide ice sheet to grow up along slope surface；Or prolong ice sheet
The push plate plate face that disappears growth, changes ice sheet thrust direction, mitigates the pressure to protecting slope of dam face.Since the push plate that disappears increases and slope surface
Contact surface, decrease the ice pressure on bank protection slope surface unit area, so that ice is persistently increased bank protection static pressure and become gradually to subtract
Small dynamic pressure is protected protecting slope of dam not squeezed locally directly by ice sheet and is destroyed.After ice sheet spring melts, the push plate that disappears is fallen back to by self weight
The water surface, next winter continue to play a role.

Specific embodiment
Referring to Fig.1, specific embodiment of the present invention is: waterproof mortar layer 5, waterproof mortar are applied on protecting slope of dam face
Layer is Flexible Sliding layer 6 above, is equipped with several push plates 4 that disappear being mounted side by side above Flexible Sliding layer, the push plate bottom that disappears is placed in limit
On the supporting plate 7 of position.1 is ice sheet, and 2 be broken ice sheet, and 3 be the drag-line for connecting all push plates that disappear, and the Flexible Sliding layer is poly-
Tetrafluoroethene plate, plate body hard, surface are smooth.
Referring to Fig. 2-Fig. 5, the high strength reinforced concrete skewback that push plate is upper-thin-lower-thick that disappears, by cold-rolled strip
Rib reinforcement 9 and C50 concrete 10 are constituted, and pre-buried anchor ring 8 is contacted by drag-line 3 and is fixed on dykes and dams top at the top of the push plate that disappears
Portion.
Referring to Fig. 6, the limit supporting plate is L shape, is made of cold rolled reinforcing steel bar with ribs 9 and C50 concrete 10, and and dykes and dams
The anchor connection of slope protection face.
The utility model Specific construction process:
The push plate 1. prefabricated reinforced concrete disappears, conserve to reach transport installation intensity when transport dykes and dams erecting bed to；
2. reinforcing smooth dykes and dams, slope protection slope surface, waterproof mortar layer is applied on protecting slope of dam face, is soft above waterproof mortar layer
Property sliding layer, water level before the winter is entered according to reservoir, lake, installation limit supporting plate is fixed in top of the slope or dam crest installation the push plate drag-line that disappears
Anchor ring；
3. selecting manpower installation or crane installation method that the push plate that disappears is mounted side by side on the Flexible Sliding layer of protecting slope of dam face, disappear
Plate surfaces want smooth, seam tight, play a role to the ice sheet formation push plate that disappears.
Disappear push plate under ice sheet promotion along protecting slope of dam slope surface upward sliding, guide ice sheet to grow up along slope surface；Or make ice sheet
Prolong the push plate plate face growth that disappears, change ice sheet thrust direction, mitigates the pressure to protecting slope of dam face, protect protecting slope of dam not by ice sheet
Directly part, which squeezes, destroys.
