Description

A kind of external hanging type baffle prestress anchorage cable peg board retaining wall
Technical field
It the utility model is related to a kind of stake plate type retaining wall, more particularly to a kind of external hanging type prestress anchorage cable peg board earth-retaining Wall.
Background technology
Stake plate type retaining wall is developed by anchor pile, is most applied to earlier than the seventies in last century in cut slope, often Using cantilevered peg board wall construction, after with the accumulation of experience, be gradually available for the supporting of embankment.The height of stake plate type retaining wall can From the limitation of general retaining wall height, and due to the use of pile foundation, it is strong in the poor Regional suitability of geological conditions.
Common stake plate type retaining wall generally uses borehole pile, and ancestor's break is every borehole, then pours pile foundation, treats that pile foundation reaches Breast boards is installed again after to design requirement.Such a construction method to general embankment supporting or mountain area cutting supporting strong applicability, but The supporting to form highway cut is excavated for city existing building plot there are obvious shortcoming, is in particular in following several respects: 1st, the presence of plot existing building determines that supporting construction excavation construction is limited, and the displacement limit in digging process to foundation pit top System is tighter;2nd, the deep excavation construction infection scope of earthen foundation is larger;3rd, supporting construction will be used as highway cut barricade forever in itself Exist long, its alien invasion has certain landscape requirement.
Utility model content
For problems of the prior art, the utility model provides a kind of external hanging type baffle prestress anchorage cable peg board Retaining wall, can strictly control peg board retaining wall wall top displacement.
Technical solution according to the present utility model, the external hanging type baffle prestress anchorage cable peg board retaining wall, including more Bored concrete pile, anchor cable, external hanging type baffle and the Guan Liang on bored concrete pile top, the external hanging type baffle plate setting is outside the top of bored concrete pile Side, anchor cable are arranged on the external hanging type baffle between bored concrete pile, and external hanging type baffle is equipped with least row's anchor cable, external hanging type baffle On be additionally provided with spilled water hole.
Further, the anchor cable is prestress anchorage cable.
Further, the anchor cable includes anchoring section and free segment, and the upper thickness of earth covering of the anchoring section is at least 4m.
Further, the angle between the anchor cable and horizontal plane is more than 10 °.
Further, the anchored end of free segment is equipped with anchoring reinforcement block in external hanging type baffle inner wall on the anchor cable.
Further, the section of the bored concrete pile is circle.
Further, a diameter of 800-1500mm of the bored concrete pile.
Compared with prior art, structure of the present invention is in security, applicability, construction conveniency, the feature of environmental protection, economical and beautiful etc. Aspect is with the obvious advantage, there is preferable application prospect in urban road construction:The bored concrete pile of peg board retaining wall is drilled using convenient The circular cross-section of construction, avoids excavating pile;By the setting of external hanging type baffle meet at the same time between grout pile earth-retaining function with Landscape retaining wall demand;By the way that the setting of prestress anchorage cable strictly controls peg board retaining wall wall top on external hanging type baffle between grout pile Displacement, protects existing building.

Embodiment
With reference to specific embodiments and the drawings, the invention will be further described.
As shown in Figure 1 and Figure 2:A kind of external hanging type prestress anchorage cable peg board retaining wall, more bored concrete piles 1, anchor cable 4, external hanging type The Guan Liang 2 on 1 top of baffle 3 and bored concrete pile.External hanging type baffle 3 is arranged on the upper outside of bored concrete pile 1, and anchor cable 4 is arranged on perfusion Between stake 1 on external hanging type baffle 3, external hanging type baffle 3 is equipped with least row's anchor cable 4, and spilled water hole is additionally provided with external hanging type baffle 3 5.Specifically, anchor cable 4 is prestress anchorage cable, it includes anchoring section 41 and free segment 42, wherein, the upper thickness of earth covering of anchoring section 41 At least 4m.Angle between each row's anchor cable 4 and horizontal plane is generally higher than 10 °.The anchored end of free segment 42 is plug-in on anchor cable 4 3 inner wall of formula baffle is equipped with anchoring reinforcement block, strengthens partial result.The section of bored concrete pile 1 can be circle, be avoided that excavation into Stake, its a diameter of 800-1500mm.
The construction method of the utility model external hanging type prestress anchorage cable peg board retaining wall is as follows:A. cast-in-situ bored pile 1 is carried out Construction, the buried depth of 1 pile of bored concrete pile are determined according to the factor such as soil pressure, building load, anchorage depth after wall;B. bore After hole pouring pile is constructed, Guan Liang 2 of constructing;C. plot is excavated;D. after below ground certain depth is excavated to, carry out plug-in The construction of formula baffle 3 and tensioning first row anchor cable 4;E. continue to excavate downwards, layering progress external hanging type baffle 3 is constructed and stretch-draw anchor 4 until excavation construction is completed.Wherein, anchor cable 4 should avoid building basis and be anchored, and anchorage cable anchoring section should avoid being arranged on element Banket, in the unfavorable geology such as mud soil property,
Embodiment 1:Cutting depth is 6m or so, and the quantity of anchor cable 4 on facade grow from top to bottom by totally three rows, suitable Guan Liang 2 Spend direction anchor cable 4 to set together by 1.5m spacing, the length of 15m, wherein anchoring segment length 10m, applies prestressing force 180KN.With Peg board retaining wall overhead height is H, and wherein 4 tensioning of first row anchor cable is highly H-0.3m, and angle with horizontal plane is 15 °;Second The tensioning of row's anchor cable 4 is highly H-3.3m, and angle with horizontal plane is 15 °;The tensioning of 3rd row's anchor cable 4 is highly H-5.8m, with Horizontal plane angle is 20 °.External hanging type baffle 3 using thickness 35cm armored concrete panel, its surface can hanging plate do feature wall, Spilled water hole 5 is opened up at 3 distance from bottom ground 30cm of external hanging type baffle.Bored concrete pile 1 is the cylindrical stake that diameter of section is 1m.Second The anchored end for arranging free segment 42 on 4 and the 3rd row's anchor cable 4 of anchor cable is equipped with anchoring reinforcement block on 3 inner wall of external hanging type baffle.
The structure of the utility model is in security, applicability, construction conveniency, the feature of environmental protection, economical and beautiful etc. advantage Substantially, there is preferable application prospect in urban road construction:The bored concrete pile of peg board retaining wall is using the circle for facilitating drilling construction Tee section, avoids excavating pile;Earth-retaining function and Landscape retaining wall between grout pile are met by the setting of external hanging type baffle at the same time Demand;By the way that the setting of prestress anchorage cable strictly controls peg board earth-retaining wall top displacement on external hanging type baffle between grout pile, protection Existing building.
