Description
Technical field
The utility model relates to a kind of retaining wall structure, particularly a kind of high wall-retaining structure of combining pile foundation and prestress anchorage cable.
Background technology
Retaining wall refers to supporting Roadbed Soil or the hillside soil body, prevent from banketing or the structure of soil deformation unstability.Different according to its rigidity and displacement mode, rigid retaining wall, flexible retaining wall and temporary support three class can be divided into.Different according to the setting position of retaining wall, be divided into curb wall, embankment wall, cutting wall and hillside wall etc.And divide by wall height: wall is high≤the common retaining wall of genus of 5m, and wall is high >=the high retaining wall of genus of 8m.When the wall of retaining wall is too high, in order to increase the bending rigidity of cantilever, longitudinally arranging one counterfort at a certain distance along wall is long, is counterfort retaining wall.Prestressd anchor cable construction technology is mainly used in Reinforcement Works of Rock Slopes at present, is all widely used at construction fields such as water conservancy and hydropower, highway, railway, mines.What traditional anchor cable construction was more is applied to rock slope, apply less in the collapsed accumulation body of complex geologic conditions and the side slope of deep covering layer, studying carefully its main cause has two, and one is anchor cable pore-creating difficulty, two is slip casting difficulties, is difficult to free section of anchor cable to fill.
For high retaining wall or retaining Wall, single reinforcing reinforcement props up gear measure to be difficult to meet the resistant slide of high retaining wall and the stability requirement of overturning or slip resistance analysis, particularly in the large-scale important people's livelihood, infrastructure construction engineering, for ensureing the construction of high barricade, the requirement of design and use, various combined type height wall-retaining structure is developed application gradually, as compound height retaining wall structures such as anchor shaft anchor cable class reinforced earth height barricade, pile formula Earthworking reinforced bar height retaining walls.These high retaining wall structures, except respectively having except advantage, also have its shortcoming and applicability, as: when high retaining wall carrying important building or traffic loading, its resistant slide scarce capacity; The ability of opposing geological disaster is more weak etc.
Therefore, need badly at present seek a kind ofly have that resistant slide resistance to capsizing ability that is high, that resist geological disaster is strong, reliable construction quality and the wall-retaining structure that second consolidation can be avoided to safeguard seems very important.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of and have the pile foundation prestressd anchor cable height wall-retaining structure that resistant slide resistance to capsizing is high, the ability of resistance geological disaster is strong.
This pile foundation prestressd anchor cable height wall-retaining structure, comprise the section of bearing down on one, outrigger base, base plate, pile tube, diagonal brace and anchor cable, the section of bearing down on one is arranged on outrigger base top, base plate is positioned at bottom outrigger base, pile tube embeds in the soleplate, arrange diagonal brace after outrigger base and be fixed on base plate top, diagonal brace is connected with outrigger base and base plate with the 4th fixed end by the 3rd fixed end, and anchor cable passes through the first fixed end and the second fixed end is inner through outrigger base, base plate and pile tube.
As preferably: the section of bearing down on one and base plate are reinforced concrete structure, arrange the second fixed end at the section of bearing down on one top, arrange the 4th fixed end on base plate top, are vertically provided with the first anchor cable preformed hole for connecting anchor cable in outrigger base.
As preferably: interval, outrigger base thickness of slab direction arranges outfall.
As preferably: built expansive concrete in the inner certain limit of pile tube, and fixed end is arranged in expansive concrete.
As preferably: anchor cable is divided into long anchor cable and short anchor cable, outrigger base, base plate are firmly connected with pile tube with the second fixed end with first fixed end at the section of bearing down on one top by being arranged on pile tube inside by long anchor cable, and base plate is firmly connected with pile tube with the 4th fixed end with first fixed end at base plate top by being arranged on pile tube inside by short anchor cable.
As preferably: described first fixed end, the second fixed end, the 3rd fixed end and the 4th fixed end are embedded.
The utility model has following feature and beneficial effect:
Pipe pile foundation is set under the base plate of high barricade, and pipe pile foundation is embedded in the base plate under outrigger base, ensure that the base plate of high wall-retaining structure and pile tube are connected as a single entity, enhance the globality of high wall-retaining structure from retaining wall foundation.
The section of bearing down on one is set at barricade breast boards top, and anchor cable preformed hole is set when building, after anchor cable is introduced, after outrigger base, base plate reach some strength, carry out stretch and inject, ensure that the smooth precompressed of long anchor cable, in addition, the section of bearing down on one also has circle beam action, ensures high barricade Equalsettlement.
In pipe pile foundation, prestress anchorage cable is set according to designing requirement, anchor cable top is arranged at outrigger base and base plate top respectively, combined closely firm to outrigger base, base plate and pile tube by long anchor cable and short anchor cable, fundamentally ensure that the resistance to plucking of high wall-retaining structure, anti-slipping property and anti-overturning.
