Description

Prestressed anchor waveform sheet pile retaining structure
Technical field
This utility model relates to a kind of supporting construction, particularly relates to a kind of prestressed anchor waveform sheet pile Retaining structure.
Background technology
During underground engineering Facilities Construction, keeping foundation ditch and going along with sb. to guard him is stably an important content, Cast-in-place concrete support pile is one of conventional method as supporting construction.Supporting construction form and kind Numerous, as Deep-stirred Soil-cement barricade, reinforced cement earth stirring diaphragm wall, cast-in-situ bored pile barricade, Diaphram wall, precast concrete pile etc..Wherein, high-strength prestressed waveform sheet pile is prefabricated as one Concrete-pile has structure gear soil cross section greatly because of it compared with traditional concrete support stake, the construction period Short, the advantages such as construction technology is advanced, develop rapidly during underground engineering Facilities Construction, but its section Face size is less, and rigidity is less, it is possible to crosses ambassador's sheet pile because of horizontal loading and lost efficacy or deformed excessive, Design requirement can not be met, even may ftracture because stress is excessive with base plate of foundation pit junction.
At present, waveform sheet pile is mostly rendered as a kind of cantilevered, horizontal lotus as its top of supporting construction Carrying (water, soil pressure etc.) major part and rely on the strength support of sheet pile itself, therefore sheet pile self bears Bigger moment of flexure and shearing, under operating mode as bigger in cutting depth, may cross ambassador's sheet pile because of horizontal loading Lost efficacy or deformed excessive, it is impossible to meeting design requirement, even with foundation ditch (river course etc.) back plate connections May ftracture because stress is excessive, cause project failure.
Utility model content
This utility model purpose is the advantage utilizing waveform sheet pile and suspension roof support, and exploitation one can be wide General apply to prop up in the infrastructure constructions such as gear, river course revetment, seashore loke shore, embankment slope at foundation ditch hold Structure is kept off by the prestressed anchor waveform sheet pile composite support under greater level load case..
For realizing above-mentioned utility model purpose, the technical solution of the utility model is: prestressed anchor ripple Shape sheet pile retaining structure, including waveform sheet pile, anchor hole, anchor pole, described waveform sheet pile is prestress steel Tendon concrete structure, including top board, web and base plate, section form is rendered as waveform, two flanks Plate is respectively provided with a raised line and groove, built-in prestressed reinforcement framework, and thickness is more than 100mm, coagulation The grade of soil is not less than C40;Top board is provided with the anchor hole passed for anchor pole, and anchor hole is cylinder, anchor The diameter in hole is more than 50mm, is provided with the intensive aspect preventing waveform sheet pile stress from concentrating at anchor hole, strengthens Anti-corrosive antirusting paint is scribbled on body;
Anchor pole is that a single or many tendon utilizes normal pressure and high pressure to be repeatedly in the milk to form, including anchoring section, Non-anchored section and anchor head, anchor pole passes anchor hole, anchor pole and waveform sheet pile is connected by anchor head, anchor pole Anchoring section be arranged in steady soil, and by design requirement determine the size to anchor pole Shi Hanzhang;
Described anchor head include anchor tiltedly hold in the palm, anchorage, concrete sealing off and covering anchorage and mend in anchor hole slurry benefit slurry hole;
Described anchor pole is socketed with waveform steel pipe and spiral reinforcement through the outer surface of waveform sheet pile.
Preferred as one of the present utility model, described intensive aspect is steel pad.
Preferred as another kind of the present utility model, described anchor pole can also use high-strength steel bar or steel strand Silk, utilizes normal pressure or high pressure, one or many grouting to form.
The beneficial effects of the utility model are:
The most compared with prior art draw anchor formula waveform sheet pile can factorial praluction, quality controllable, produce effect Rate is high, it is to avoid the problem that site operation environmental pollution, quality control are difficult, and its sectional dimension is less, Economize on material;
2. can make full use of the natural action power of ground compared with waveform sheet pile supporting, reduce sheet pile and lost efficacy Rate, reduces sheet pile horizontal distortion, reaches to design requirement;
3., compared with suspension roof support, engineering excavation face can be set to vertical surface, decreases earthwork excavated volume, Therefore save financial resources, material resources, but also decrease the environmental pollution caused because of earth excavation, fully Respond the call of China's Ecological Civilization Construction;
4. can realize constructing without inner support, increase excavated section and construction space, accelerate efficiency of construction, Shorten the construction period.
