Description
Technical field
The utility model relates to the used three-dimensional water discharging body of a kind of preloading soft soil foundation; Be particularly related to and a kind ofly can be applicable to that vacuum preloading, piling prepressing, well-points dewatering etc. need set in the various soft base and soil body treatment project of water discharging body in ground to the three-dimensional water discharging body of a plurality of direction drainings.
Background technology
Preloading is one of Soft Ground method, and is different according to the load that applies, and can be divided into vacuum method and preloading again; Wherein vacuum method is on the basis of the sand cushion that sets, vertical drainage body, filter pipe, seals with the soft soil that is reinforced the formation vacuum of bleeding with closing membrane; Make and produce negative pressure in sand cushion and the vertical drainage passage; And then the generation precompression, the pore water under the effect of precompression in the foundation soil flows in the vertical drainage body continuously, and pore water enters into chimney filter through vertical drainage body; And then excrete, foundation soil is accomplished fixed.This method is proposed in nineteen fifty-two by the W. Kjellman of geological institute of Sweden imperial family, after multinational sequential trial, the utilization of just in the reinforcing soft foundation of U.S.'s Philadelphia International Airport runway, succeeing first until 1958.China during 1957 ~ 1961 years successively in Tianjin, ground such as Shanghai and Harbin carry out overtesting research, just promote the use of after until on December 7th, 1985 through national-level appraisal.Vacuum method in China's successful Application near twenty or thirty year, but also run into many problems, wherein vertical drainage body adopts the row's of moulding plate and the sand drain that drainage direction is single, drainage path is relatively long always; The row's of moulding plate has been wasted a large amount of natural resources as disposable vertical drainage body, and the row's of moulding plate and sand drain all exist and smear and the well inhibition effect; The drainability of its middle and later periods reduces greatly; Its drainage effect almost disappears during to the later stage, has had a strong impact on the consolidation draining speed of foundation soil, and the precompressed cycle is often longer; So expend the more energy (electric energy); Can't satisfy subtract instantly can the row of saving demand, in addition, the foundation soil bulk strength after traditional vertical drainage body is handled is uneven, low from water discharging body intensity far away.In sum; The vacuum method of the existing vertically row of moulding plate or sand drain associating can't reach the purpose that the precompressed cycle shortens; Can't be fast and reinforce the barged-in fill ground in high quality; And consume a large amount of natural resources and the energy, can not accomplish the purpose of energy-saving and emission-reduction, the preloading of other type also is faced with such problem simultaneously.
The utility model content
The purpose of the utility model overcomes above-mentioned defective exactly, provides a kind of preloading soft soil foundation used three-dimensional water discharging body, and is three-dimensional, multidirectional, can reuse.
The three-dimensional water discharging body that a kind of preloading soft soil foundation is used; Comprise the vertical drainage pipeline; It is characterized in that pipeline opening being set at the sidewall of vertical drainage pipeline; In the pipeline opening coupling for fixed pipe installations, lateral drainage piping erection can rotate the lateral drainage pipeline at vertical direction in pipe joint, and vertical drainage pipeline and lateral drainage pipeline evenly are provided with permeable hole.
The three-dimensional water discharging body that aforesaid preloading soft soil foundation is used is characterized in that at pipe joint and lateral drainage pipeline through relative bolt, the lateral drainage pipeline is that axle rotates with the bolt at vertical direction.
The three-dimensional water discharging body that aforesaid preloading soft soil foundation is used is characterized in that the parcel screen pack in the outside of vertical drainage pipeline and lateral drainage pipeline.
The three-dimensional water discharging body that aforesaid preloading soft soil foundation is used is characterized in that at the two ends of vertical drainage pipeline end thread being set.
The three-dimensional water discharging body that aforesaid preloading soft soil foundation is used is characterized in that the end sealing of lateral drainage pipeline away from the vertical drainage pipeline, other end opening, and offer bolt hole.
The water discharging body of the utility model has following characteristics and beneficial effect:
(1), the lateral drainage pipeline being set on the vertical drainage pipe shortens the drainage path of foundation soil greatly; Drainage direction becomes three-dimensional from traditional unicity, can know according to the knowledge of soil mechanics, and what drainage path was reciprocal square is directly proportional with consolidation time; Therefore; Under identical overlying burden condition, shorten squeeze time, realize the rapidity and the high efficiency of treatment of soft foundation.
(2), have solid, multidirectional characteristics; Make the foundation soil consolidation draining more even; Foundation soil total bearing capacity after the processing improves evenly, avoided foundation soil bulk strength after traditional vertical drainage body is handled uneven, from defectives such as water discharging body intensity far away are low.
(3), the lateral drainage pipeline can rotate through the circular arc that bolt can carry out about 0 ° ~ 90 °; When on when pulling out three-dimensional water discharging body; The lateral drainage pipeline becomes with the vertical drainage pipeline and is the approximate parastate about 0 ° by being near normal state about 90 ° with the vertical drainage pipeline, resistance and scratching surrounding soil when pulling out three-dimensional water discharging body on having reduced.
(4), in the perforate of draining even tube wall, the pipe outer wall wrap up geotechnological seepy material, water discharging body promptly can bear lateral earth pressure, can also guarantee the smooth discharge of ground mesopore water.
(5), adopting the mode of cell cube assembling to connect into design sets needed length, has avoided the inconvenience of making, transportation and construction.
(6), can reuse.
