Description
Technical field
The utility model relates to the space enclosing structure that the stake of hybrid reinforcement H template is combined with five axle Soil-cement Walls.This space enclosing structure is applicable to foundation ditch and the native sealing of gear is gone along with sb. to guard him in river course.
Background technology
The developed areas such as China's Yangtze River Delta, the annual expense for bracing of foundation pit is up to more than 100,000,010,000 yuan, the soil-baffling structure adopting in China's bracing of foundation pit at present mainly contains diaphragm wall, castinplace pile, the stake of SMW engineering method, soil nail wall and piled anchor structure, and the construction technology of these structures respectively has pluses and minuses.
Shallow foundation utilizes the situation of two axle mixing pile construction gravity dams a lot of in hole, two axle agitation pile technology are born in the eighties and are adopted so far always, frame is well cabinet frame, walk tubular type walking, stability extreme difference, work efficiency is very low, and labour intensity is large, another unit head partly adopts the conventional motor of 37kw, and starting is short of power.The darkest stake is long only has 18m, and bottom drilling rod only has two road blades, stirs inhomogeneously, and three stir two is sprayed into quality of pile and is also difficult to guarantee, 1.2 meters one group of each pile, causes the cold seam of stake overlap joint many, easily causes the phenomenon such as leak.
In SMW engineering method employing triaxial cement mixing pile, insert H shaped steel and come sealing and gear soil.This engineering method has that cost is relatively low, the duration is short, water-resisting property is strong, to features such as surrounding environment influence are little.After basement construction completes, H shaped steel can be extracted from cement mixing method, reaches the object that reclaims and again utilize.Therefore it is short that this engineering method is compared not only the duration with the form of going along with sb. to guard him of routine, and work progress is pollution-free, place clean and tidy clean, noise is little, and can save social resources, avoids safeguarding that body forever leaves in underground after basement construction, becomes underground obstacle.But there is following shortcoming in the stake of SMW engineering method: in the stake of SMW engineering method, mostly use H shaped steel.In actual construction work use procedure, the freight of shaped steel and lease expenses are all very high, and especially, in longer situation of duration, the lease expenses of shaped steel can increase use cost greatly.SMW engineering method pile driving construction need to be jet in addition, and cement mixing content is large (20%-22%), has the displacement soil of 20%-30% in work progress, cause environment pollution, and pile strength of the mixing pile is lower.
The cost of castinplace pile campshed enclosure wall is relatively excessive, and when construction the peripheral water seal curtain of need first constructing, then the castinplace pile campshed of constructing, has caused the dilatory of duration like this.
Consideration based on duration and cost aspect, the form of going along with sb. to guard him of implanting in recent years preformed pile in agitation pile is more and more subject to insider's concern, has also had a lot of Project cases simultaneously, and after construction, effect is better.But the method for implanting preformed pile in conventional agitation pile is: with motor eccentric vibrating hammer shake into.It is large that this method has vibration wave, shakes into the feature such as speed is slow.Preformed pile arrangement of reinforcement can be used high strength cast iron in addition, high tensile reinforcement tensile strength is high and low relaxes, has good upsetting performance, but high strength cast iron bendability and welding performance are very poor, so cause the bad overlap joint in preformed pile pile cover place with high strength cast iron arrangement of reinforcement, can only do single-unit stake.
The utility model has solved the deficiency of above-mentioned several techniques, has merged the bending resistance of prefabricated units and the stagnant water effect of structural performance and agitation pile simultaneously, than traditional space enclosing structure the utility model can significantly shorten the construction period, pollution-free, reduced cost.
Utility model content
The purpose of this utility model be exactly in order to overcome the defect that above-mentioned prior art exists, provide that a kind of bending resistance shear behavior is good, cost is low, effect is high, pollution-free, more piece can connect and can do the long space enclosing structure that dark novel hybrid reinforcement H template stake is combined with five axle Soil-cement Walls of doing.
The purpose of this utility model can be achieved through the following technical solutions:
The space enclosing structure that the stake of a kind of hybrid reinforcement H template is combined with five axle Soil-cement Walls, described space enclosing structure comprises, hybrid reinforcement H template stake and five axle Soil-cement Walls wherein, dispose high strength cast iron and conventional reinforcing bar in described hybrid reinforcement H template stake simultaneously.
Described high strength cast iron and conventional reinforcing bar are provided with many, and are distributed in respectively in the stake of H template.
Described its pile body diameter of five axle Soil-cement Walls is 500mm-1200mm.
Described hybrid reinforcement H template stake comprises middle interconnecting piece and two ends connecting portion, and middle interconnecting piece both sides and connecting portion termination, two ends are all provided with embedded iron.
In described hybrid reinforcement H template stake, high strength cast iron is through anchor plate, by anchorage head, realizes and being connected of anchor plate, and conventional reinforcing bar is realized and being connected of anchor plate by welding.
Described high strength cast iron is steel bar for prestressed concrete, is also tubular pile wire, PC rod iron, and its tensile strength is not less than 1420Mpa, and reinforcing bar adopts interior indentation.
Between described hybrid reinforcement H template stake, by welding between embedded iron separately, form more piece form.
Compared with prior art, the utlity model has following advantage:
1. a hybrid reinforcement H template stake, it has improved the rigidity of sheet pile, has increased the durability of sheet pile, has reduced vibration and elastic deformation, has strengthened bending resistance shear behavior, can greatly reduce the deflection of foundation ditch.
2. keep off soil with conventional insert H shaped steel, the conventional steel bar concrete sheet pile of H type and bored pile in cement-soil, Soil-cement sealing is compared, and can reduce costs 10-40%.
3. the stake of hybrid reinforcement H template is that batch production is produced, and to Site Welding, length is controlled, for underground 1～4 layer depth Foundation Pit Support Engineering of foundation ditch, is widely used.
4. hybrid reinforcement H template Zhuan Shi factory is customized, to on-the-spot just welding, then inserts in five axle cement mixing methods, and pollution-free without mud, the duration shortens greatly, and civilized construction degree is high.
5. former diaxon stirs because blade only has two roads, reaching that quality requirement need stir is that two sprays three are stirred, i.e. Three Up Three Down, and existing five axle cement mixing method technology adopt blades to increase by 2.5 times, reached one on the other the mixing effect of Three Up Three Down, whitewashing when lower brill is carried brill together.
6. in addition, compared with prior art, five five of axle cement mixing method one time piles adopt the piling of high-frequency hydraulic vibration hammer simultaneously, and pile sinking speed is fast, and efficiency of construction is high.
