Abstract
The utility model discloses a pile-supported cantilever retaining wall, which comprises a cantilever retaining wall, wherein the cantilever retaining wall consists of a bottom plate and a vertical wall arranged above the bottom plate. The pile-support cantilever retaining wall is characterized in that a cast-in-place bored pipe is arranged below the bottom plate and is rapidly connected with the bottom plate. The pile-supported cantilever retaining wall is simple in structure, can solve the problem that the bearing capacity of foundation soil does not meet the basement stress on the premise of not increasing the size of the bottom plate, and has the beneficial effects of improving the anti-overturning force and anti-slippage force.
Description
Technical field
The utility model relates to the retaining wall field, is specifically related to a kind of pile cantilever retaining wall.
Background technology
At present, cantilever retaining wall is commonly referred to as by base plate and is fixed on that wall on the base plate constitutes, and mainly leans on the weight of banketing on the base plate to keep stable retaining wall, and the wall height generally should not be above six meters.Because the cantilever retaining wall quantity of masonry is little, simple structure, easy construction can adapt to softer ground, has obtained fast development around the overturning or slip resistance analysis power that improves cantilever retaining wall and the improvement technology of anti-skid force in the last few years.Application number is 200820223651 to disclose a kind of Cantilevered type retaining wall reinforcement composite structure; Through stratification in the filler behind wall the GSZ lacing wire is set; Improve the overturning or slip resistance analysis power and the size that has in a disguised form increased base plate simultaneously of retaining wall; Thereby improved anti-skid force, thereby reduced quantity of masonry.But the overturning or slip resistance analysis power and the anti-skid force that improve retaining wall through this kind method are limited; And can't under the condition that does not reduce base plate size, solve the problem that bearing capacity of foundation soil does not satisfy base stress; Especially invade when using in the limit roadbed at soft foundation, karst region and railway, highway and have certain limitation, hindered further applying of the type retaining wall.At present, do not find to have as yet under the prerequisite that does not increase base plate size, to solve the problem that bearing capacity of foundation soil does not satisfy base stress, and can improve the retaining wall of overturning or slip resistance analysis power and anti-skid force.
The utility model content
The purpose of the utility model is in order to solve the deficiency that the above-mentioned background technology exists; Propose a kind of simple in structure, can under the prerequisite that does not increase base plate size, solve the problem that bearing capacity of foundation soil does not satisfy base stress, and improve the pile cantilever retaining wall of overturning or slip resistance analysis power and anti-skid force.
In order to realize above purpose, a kind of pile cantilever retaining wall that the utility model provides comprises cantilever retaining wall, and said cantilever retaining wall is made up of base plate and the wall of being located at the base plate top, and it is characterized in that: said floor below is provided with bored pile.
Specifically, said cantilever retaining wall and bored pile are reinforced concrete structure, and cantilever retaining wall and bored pile are rigidly connected.
Preferably, said bored pile has four, evenly vertically is arranged in floor below.
Preferably, the wall chest of said wall is vertical ratio of slope, and the ratio of slope of the wall back of the body is 1: 0.1～1: 0.3; The stake footpath of said bored pile is 0.8～1.5 meter; The length h that base plate is stretched on the stake top of bored pile is 5～20 centimetres.
The beneficial effect of the utility model: one of which, only below original cantilever retaining wall, set up bored pile, simple in structure; Its two, bored pile is hidden under the ground, can not cause the increase of base plate size, has effectively practiced thrift area; Its three, bored pile has bigger resistance to compression, resistance to plucking and anti-horizontal external bearing capacity, can improve overturning or slip resistance analysis power, skid resistance and the bearing capacity of foundation soil of cantilever retaining wall greatly.
Description of drawings

Among the figure: cantilever retaining wall 1; Bored pile 2; Spilled water hole 3; Base plate 1.1; Wall 1.2.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment: extremely shown in Figure 3 like Fig. 1; A kind of pile cantilever retaining wall that the utility model designed; Comprise cantilever retaining wall 1; Said cantilever retaining wall 1 is made up of base plate 1.1 and the wall 1.2 of being located at base plate 1.1 tops, and the wall chest of said wall 1.2 is vertical ratio of slope, and the ratio of slope of the wall back of the body is 1: 0.1～1: 0.3.Base plate 1.1 belows also are provided with four bored piles 2, evenly vertically are arranged in base plate 1.1 belows.Wherein, cantilever retaining wall 1 is reinforced concrete structure with bored pile 2, and cantilever retaining wall 1 is rigidly connected with bored pile 2.The stake footpath of said bored pile 2 is 0.8～1.5 meter; The length h that base plate 1.1 is stretched on the stake top of bored pile 2 is 10 centimetres, and the main muscle of bored pile 2 and spiral stirrup anchor into the requirement that the interior length of base plate should satisfy " Code for design of concrete structures " (GB 50010-2010).
Work progress is: (1) is provided with two rows in subgrade cross section direction, longitudinal section direction in foundation soil, and two of every rows are totally four bored piles 2.
(2) bored pile 2 pile foundations and cantilever retaining wall 1 base plate 1.1 are rigidly connected.
(3) bored pile 2 pours into the concrete of cantilever retaining wall 1 simultaneously, guarantees the globality of structure.
(4) setting is carried on the back to the spilled water hole 3 of wall chest 4% gradient by wall in the wall 1.2, and every separated 2m upper and lower, left and right are crisscross arranged, and the pvc pipe that diameter is 0.1m is set in the spilled water hole 3.
(5) this pile cantilever retaining wall 1 every joint 10m～20m is provided with build joint, reduces the secondary internal force that is produced by temperature and differential settlement.
(6) after the concrete of bored pile 2, wall 1.2 and base plate 1.1 reaches design strength, promptly form " pile cantilever retaining wall ".
The utility model adopts bored pile 2 and cantilever retaining wall 1 base plate 1.1 to be rigidly connected; Stressed clear and definite with force path; Base plate 1.1 is given pile foundation with the Load Transfer such as pressure that deadweight, upper load and wall 1.2 bear; Pass to foundation soil by pile foundation again, reached the purpose that improves overturning or slip resistance analysis power and anti-skid force under the prerequisite that does not increase base plate 1.1 sizes.Bored pile 2 bearing capacities are high in addition, and are embedded in the ground, make pile cantilever retaining wall 1 not receive the restriction of geological conditions, in soft foundation, karst roadbed, higher reliability arranged also, and are applied widely.
The above only is the preferred embodiment of the utility model, is not the utility model structure is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
