2. the setting of baffle: pouring the slip casting back up coat on the baffle, support column, foundation pile and former cantilever retaining wall panel can play the supporting role to the slip casting back up coat for the bearing capacity of newly-widened partial road surface structure becomes more stable, also can reduce the settlement effect of newly-widened road surface loaded.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the widened embankment structure for the high retaining wall filling section near the water suspension wall mainly comprises an original pavement structure 1 and a newly widened partial pavement structure. The new widened partial pavement structure comprises a waterproof inclined wall 2, an inclined wall connection 3 and a retaining wall panel support. The inclined wall connection 3 is a connecting column made of reinforced concrete, and two ends of the inclined wall connection 3 are respectively connected and fixed with the waterproof inclined wall 2 and the original cantilever retaining wall panel 11. Retaining wall panel supports including a plurality of support columns 5 and foundation pile 6, and support column 5 and foundation pile 6 are made by concrete and reinforcing bar, 5 one end of support column and 6 fixed connection of foundation pile, the other end and 11 fixed connection of former cantilever retaining wall panel. Ground foundation pile 6 set up the stability that can improve the part structure of new-widening road surface on the one hand, and foundation pile 6 can play the support fixed action to former cantilever retaining wall panel 11 with the setting of support column 5, and waterproof skew wall 2 can improve the steadiness ability of waterproof skew wall 2 through skew wall connection 3 like this, further improves the stability of the part structure of new-widening road surface.
A waterproof interlayer 7 is arranged below the foundation pile 6, the waterproof interlayer 7 is integrally connected with the waterproof inclined wall 2, and a sealing structure is formed between the waterproof inclined wall 2 and the waterproof interlayer 7, so that water below the waterproof interlayer 7 and outside the waterproof inclined wall 2 is prevented from entering the newly widened part of the pavement structure through a gap between the waterproof interlayer 7 and the waterproof inclined wall 2.
Newly widen partial road surface structure including newly drawing the road surface, newly rubbing 4 below of road surface and having laid slip casting back up coat 8, slip casting back up coat 8 mainly comprises concrete and mud stone mixture, makes newly widening partial road surface structure and becomes comparatively firm like this. In order to reduce deformation and sinking of a newly-widened part of pavement structure under the action of pressure, the supporting columns 5 are fixedly sleeved with the plurality of baffles 9, the baffles 9 are perpendicular to the supporting columns 5, and thus the baffles 9 and the supporting columns 5 can play a certain supporting role under the condition that the grouting reinforcement layer 8 is under the action of external pressure.
The horizontal reinforcement body 10 is laid below the waterproof interlayer 7, the horizontal reinforcement body 10 penetrates through an original cantilever retaining wall panel 11 to be connected with an original pavement structure 1, the vertical reinforcement body adopts a screw-thread steel bar with the length of 2000mm and the diameter of 16mm HRB345, the length of the section of the vertical reinforcement body extending into a solidified soil layer is 800mm, and the vertical reinforcement body are arranged at intervals of 500 mm. A waterproof interlayer 7 is laid between the new road-expanding surface 4 and the grouting reinforcing layer 8, and the waterproof interlayer 7 adopts a needle-punched non-woven fabric and PE film composite non-woven geotextile.
In order to reduce the ponding on the new road surface of rubbing 4, reduce ponding infiltration to the part road surface structure of newly widening inside, the new road surface of rubbing 4 upper surfaces are equipped with a plurality of escape chutes.
The implementation principle of the embodiment is as follows: when the staff is widening former road surface structure 1, can set up foundation pile 6 earlier, be connected support column 5 and foundation pile 6 and former cantilever retaining wall panel 11 fixedly, play the supporting role to former cantilever retaining wall panel 11, later utilize skew wall to connect 3 and be connected waterproof skew wall 2 and former cantilever retaining wall panel 11 and fix with 3 boards of skew wall connection, later the staff lays waterproof interlayer 7 in foundation pile 6 top, and pour slip casting back up coat 8 in waterproof interlayer 7 top after being connected fixedly with waterproof skew wall 2 through concrete with waterproof skew wall 7, later be provided with waterproof interlayer 7 in slip casting back up coat 8 top, and lay new road surface 4.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
