Preferably, the concrete lift with a thickness of 10cm-20cm.
Preferably, the concrete cushion with a thickness of 3-5cm.
Compared with prior art, the utility model has the beneficial effects that the utility model on top plate clay model by being equipped with
Blinding concrete, polyethylene benzene plate and clear water bamboo slab rubber frozen prevention measures, it is ensured that (concrete strength is to reach in the construction process
Before design value) the following soil body of top plate not frost heave, after concrete strength reaches, polyethylene benzene plate plays frost heave stress buffering again and makees
With, so that some column frost heaves be avoided to hurt, by setting concrete cushion, guarantee bed die intensity, by be laid with polyethylene benzene plate every
Absciss layer, by being laid with bamboo slab rubber, carries out concrete bottom die to reach heat insulation effect.
Detailed description of the invention
Fig. 1 is the integral mold plate structural schematic diagram of the utility model.
In figure: 1- lid excavation construction top plate, 2- protect wall, 3- concrete cushion, 4- polyethylene benzene plate, 5- bamboo slab rubber, 6-
Lumps of wood bracket, 7- bind steelframe, the first crown beam of 8-, 9- concrete lift, the second crown beam of 10-, 11- concrete retaining wall, 12-
Cover board.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, a kind of extremely frigid zones lid excavation construction prevents the template knot of top plate frost heave in the utility model embodiment
Structure, including lid excavation construction top plate 1, concrete cushion 3, polyethylene benzene plate 4, bamboo slab rubber 5, binding steelframe 7 and concrete lift
9,1 both ends of lid excavation construction top plate are equipped with protection wall 2, for protecting 1 two sides of lid excavation construction top plate, lid excavation construction top
Concrete cushion 3 has been set on the upside of plate 1, is guaranteed bed die intensity, polyethylene benzene plate 4 is equipped on the upside of concrete cushion 3, to reach
Heat insulation effect is equipped with bamboo slab rubber 5 on the upside of polyethylene benzene plate 4, is preferably laid with concrete bottom die, is provided on the upside of bamboo slab rubber 5
Steelframe 7 is bound, 7 inside of binding steelframe and upside have poured concrete lift 9, convenient for increasing the heat preservation degree on top,
