Abstract
It the utility model is related to a kind of closed U-type groove structure of anti-floating, substrate is provided with below U-type groove, U-type groove both sides end face outside is provided with toe board before anti-floating type, U-type groove bottom plate upper surface both sides are fixedly connected with side wall I, side wall II is fixedly connected with side wall I, the upper surface of side wall II is provided with anti-collision structure, and U-type groove cell body upper surface is provided with retaining wall, and retaining wall upper surface is fixedly connected with anti-collision structure.U-type groove side wall outside is set into toe board before anti-floating type, so as to increase the anti-floating power of structure.
Description
Technical field
A kind of U-type groove structure is the utility model is related to, particularly a kind of closed U-type groove structure of anti-floating, belongs to city and has stable political situation
Highway construction field.
Background technology
With flourishing for economic construction of China, the communication such as railway and highway has obtained development at full speed, builds
It is required that also improved constantly with standard.In order to ensure road speed and safety, substantial amounts of railway level-crossing is all changed to grade separation shape
Formula, it is this it is flat change vertical engineering inevitably in the form of cutting under break-through cross the higher location of level of ground water, so closing
Formula U-type groove there have been.
In the higher place of some levels of ground water, only by the frictional resistance of banketing in U-type groove and both sides without
Method resists its water buoyancy, thus can be by U-type groove float, and generally we can solve this in the form of uplift pile is set
Problem.But in Practical Project case, the drawbacks of setting uplift pile, is also very more, and piling work needs to expend substantial amounts of people first
Power material resources, cost is high, long construction period.Secondly because construction joint between resistance to plucking pile head and bottom plate be present, pile crown structure type
Cause base plate waterproofing can not be closed at pile crown position.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of closed U-type groove structure of anti-floating, by outside U-type groove side wall
Side sets toe board before anti-floating type, so as to increase the anti-floating power of structure.
To solve problem above, concrete technical scheme of the present utility model is as follows：A kind of closed U-type groove structure of anti-floating,
Substrate is provided with below U-type groove, U-type groove both sides end face outside is provided with toe board before anti-floating type, and U-type groove bottom plate upper surface both sides, which are fixed, to be connected
Side wall I is connected to, side wall II is fixedly connected with side wall I, the upper surface of side wall II is provided with anti-collision structure, and U-type groove cell body upper surface is set
There is retaining wall, retaining wall upper surface is fixedly connected with anti-collision structure.
Described substrate is made up of blotter, plain concrete cushion layer and waterproof roll.
Toe board lower surface and U-type groove bottom plate lower surface are respectively positioned on waterproof roll in same plane before described anti-floating type
End face.
Described anti-collision structure is anticollision barrier.
Described retaining wall is gravity retaining wall.
The described height of side wall II is higher than retaining wall.
What the utility model was brought has the beneficial effect that：It is low to apply the more conventional uplift pile of cost for toe board before anti-floating type.Secondly, resist
Toe board applies simplicity before floating, can significantly shorten construction period.Finally, anti-floating power can be significantly increased in the structure, and will not break
The integral waterproofing system of bad U-type groove structure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- blotters, 2- plain concrete cushion layers, 3-U type groove bottom plates, toe board before 4- anti-floating types, 5- side walls II, 6-
Anticollision barrier, 7- retaining walls, 8- waterproof rolls, 9- side walls I.
Embodiment
As shown in figure 1, a kind of closed U-type groove structure of anti-floating, the lower section of U-type groove bottom plate 3 is provided with substrate, U-type groove bottom plate 3
Both sides end face outside is provided with toe board 4 before anti-floating type, and the upper surface both sides of U-type groove bottom plate 3 are fixedly connected with side wall I 9, consolidated on side wall I 9
Surely side wall II 5 is connected with, the upper surface of side wall II 5 is provided with anti-collision structure, and the cell body upper surface of U-type groove bottom plate 3 is provided with retaining wall 7, gear
The upper surface of cob wall 7 is fixedly connected with anti-collision structure.
Described substrate is made up of blotter 1, plain concrete cushion layer 2 and waterproof roll 8.
The lower surface of toe board 4 and the lower surface of U-type groove bottom plate 3 are respectively positioned on waterproof roll 8 in same plane before described anti-floating type
Upper surface.
Described anti-collision structure is anticollision barrier 6.
Described retaining wall 7 is gravity retaining wall.
The described height of side wall II 5 is higher than retaining wall 7.
Before excavation of foundation pit, dewatering well is laid in U-type groove setting area, ensures that level of ground water is located at excavation of foundation pit face in foundation ditch
0.5~1m below.
After excavation pit, first in U-type groove substrate making blotter 1, then plain concrete cushion layer 2 is set to be rolled up with waterproof
Material 8, next step construction should be carried out as early as possible after the completion of above-mentioned engineering, groove of forbidding to dry in the air is soaked.
Formwork supporting plate, the first reinforcing bar of colligation bottom plate and part side wall, pour toe board 4 before U-type groove bottom plate 3, U-type groove anti-floating type
And the concrete of side wall I 9；Then the reinforcing bar of tied part side wall, the concrete of side wall II 5 is poured, placement layer by layer, is vibrated, phase
Time interval is poured no more than 2 hours adjacent two layers, it is ensured that upper and lower two layer concrete is combined before initial set, does not form construction
Seam.
The Gravity Retaining Wall 7 between car lane and bicycle lane in U-type groove is applied, and on U-type groove side wall top and again
The top of power formula barricade 7 sets the built-in fitting of anticollision barrier.
After the completion of concreting, treat that concrete strength reaches design requirement, the dismounting that can carry out template and support is made
Industry.
The foundation ditch of symmetrical backfill U-type groove both sides, thin layer gently ram, and heavy-duty machinery must not be used to be compacted, its compacting factor must not
Less than 0.95.Car lane and banketing in bicycle lane and pavement structure are applied simultaneously.
Anticollision barrier is installed, and carries out antiseptic and rustproof processing.
Above-described is only preferred embodiment of the present utility model.It should be pointed out that the ordinary skill people for this area
For member, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, also should be regarded as belonging to this
The protection domain of utility model.
