Abstract
A soil retaining structure with different inclination angles of an anti-skid cement soil pile comprises a vertical cement soil pile, a vertical casting pile, an SMW (soil mixing wall) pile, a steel plate pile or an underground continuous wall and cement soil reinforcing piles, wherein the cement soil reinforcing piles are obliquely connected with the vertical cement soil pile, the vertical casting pile and the SMW pile through top press beams or waist beams. The sol retaining structure with different inclination angles is characterized in that the cement soil reinforcing piles are identical in length and different in inclination angle. According to the above structure, the piles are high in anti-skid performance, and anti-skid performance of a to-be-reinforced soil slope is improved greatly by the anti-skid soil retaining structure formed by combination of the vertical retaining piles and the anti-skid cement soil reinforcing piles which are constructed at different positions of a soft soil layer at the same inclination angle and in the same length.
Description
Technical field
The utility model relates to the geotechnical engineering technical field; Concrete reinforcing that relates to a kind of rock construction and supporting and protection structure, through adding cement-soil antiskid pile body in soft soil, and through combination; Form a kind of soil-baffling structure, improve its reinforcing and support capacity greatly.
Background technology
In the engineering construction in China area such as coastal, riverine, ubiquity foundation soil weakness, poor stability, the characteristics that bearing capacity is on the low side especially in the developed area, are used for ground processing and the employed expense of bracing of foundation pit, and will have more than hundred billion yuan every year.At present; In China's ground processing and bracing of foundation pit engineering; The soil-baffling structure that adopts mainly contains diaphragm wall, bored pile, soil nailing wall, SMW worker's method and piled anchor structure; Often there are many defectives in the construction technology of these structures and receive the restriction of engineering geology and construction environment, is difficult to pore-forming when running into silt soil strata, powder soil horizon or flour sand layer like soil nailing or anchor pole, the deep-mixed pile processing degree of depth is limited.Deep-mixed pile body itself usually only uses as water-stop curtain, and can not singlely use as soil-baffling structure because intensity is lower.In order to reach the native purpose of retaining, need be in deep-mixed pile H shaped steel, in diaphragm wall, bored pile combine, support or anchor pole, form soil-baffling structure, often like this cause big difficulty for design and construction, construction cost is significantly improved.
Use the difficulty of construction and the more high deficiency of cost of existence respectively in view of above-mentioned soil-baffling structure; Through experimental study for many years; We have invented a kind of new soil-baffling structure---anti-slip cement soil pile soil blocking structure; This soil-baffling structure has not only overcome all deficiencies of soil-baffling structure at present commonly used, and is a kind of not only safety, environmental protection but also economical and the new structure fast of constructing.
The utility model content
The utility model technical problem to be solved is, overcomes the problem that exists in the prior art, and a kind of soil-baffling structure that has different angle antiskid cement earth pile is provided.
For the technical scheme that addresses the above problem the utility model is such:
A kind of soil-baffling structure that has different angle antiskid cement earth pile; Comprise the cement earth pile of vertical direction, vertical castinplace pile, the stake of SMW worker's method, steel sheet pile or diaphragm wall; With with its through the stake of putting more energy into of capping beam or the oblique cement-soil that links to each other of waist rail; It is characterized in that the cement-soil pile length of putting more energy into is identical, the inclination angle is different.
A plurality of antiskid cement-soils put more energy into the stake different with the angle theta of vertical direction, θ is 0～90 °.
On the same horizontal plane a plurality of antiskid cement-soils put more energy into the stake different with the angle Φ of soil-baffling structure, Φ is 0～90 °.
The antiskid cement-soil is put more energy into stake for churning, stirring pile body, is inserted with pretensioned muscle body in the pile body, and the muscle body is steel strand or wire rope.
The beneficial effect of the utility model is:
(1) pile body skid resistance height: do same inclination angle through on the diverse location of soft layer, executing, make up, form the antiskid soil-baffling structure and increased the skid resistance that is reinforced slight slope greatly with the antiskid cement earth pile and the vertical retaining stake of length;
(2) effectively control slope displacement:, the initial displacement of side slope is eliminated when the stretch-draw through the muscle body in the oblique antiskid cement earth pile is applied pretension;
(3) the combination antislide pile becomes overall structure: set up horizontal waling the oblique antiskid pile body on the same level is all locked above that; Combine with vertical soil-baffling structure, make the oblique antiskid pile body of different level all be combined into an overall structure through vertical soil-baffling structure.
Description of drawings
Specify the utility model below in conjunction with the accompanying drawing and the specific embodiment;
Fig. 1 is the described cross-sectional view that has the soil-baffling structure of different angle antiskid cement earth pile of the utility model.
Fig. 2 is the described horizontal development structural representation that has the soil-baffling structure of different angle antiskid cement earth pile of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and Fig. 2; A kind of soil-baffling structure that has different angle antiskid cement earth pile; Comprise that vertical direction retaining stake in a row constitutes soil-baffling structure 1, soil-baffling structure is connected with the stake 2 (shown in A1, A2, A3, A4 among the figure) of putting more energy into of oblique a plurality of oblique antiskid cement-soil, and the stake of putting more energy into of a plurality of antiskid cement-soils is connected the top or the waist of retaining stake; A plurality of antiskid cement-soils pile length of putting more energy into is identical, and the inclination angle is different.A kind of specifically be the antiskid cement-soil put more energy into the stake different with the angle theta of vertical direction, θ is 0～90 °.Another kind is, the stake of putting more energy into of the antiskid cement-soil on same horizontal plane is different with the angle Φ of soil-baffling structure, and Φ is 0～90 °.Designing this kind structure can better increase the skid resistance of soil-baffling structure.
The stake 2 of putting more energy into of a plurality of antiskid cement-soils is connected on the horizontal waling at retaining stake top.
The stake 2 of putting more energy into of a plurality of antiskid cement-soils is connected on the waist rail of retaining stake waist.Among the figure, A2, A3, A4 connect waist rail 3, and A1 connects on the top, horizontal waling 4.
