The specific embodiment
Carry out the quick strengthening construction of super soft weak soil according to the following steps:
(1) constructs and forms the weak native bracing means in shallow top layer.
At first, shown in Fig. 1～4, separate curtain 01 subregion of constructing treating that stabilization zone 20 is provided with.Wherein, 10 is outside the stabilization zone among Fig. 2, and 20 is in the stabilization zone, and 30 is the mud scum surface, and 40 are the retaining plane.Because the weak ground face of land of handled ultra-soft is generally mud scum or mud, manually be difficult to lay geotextiles on the surface, after covering water, the palpus place carries out waterborne pavement by buoyancy of water.
Described separation curtain 01 comprises: plastic foam 11, batten 12, plank 13, derrick fastening devices 2, color steel 3, plastic sheeting 4.
Along the double plastic foam 11 of vertical layout of separating curtain, plastic foam 11 outward appearances are the cylinder of the long 90cm of diameter 50cm, two plastic removal strand foams, 11 horizontal spacing 0.5m, longitudinal pitch 1.4m.Every plastic removal strand foam 11 usefulness ropes and batten 12 colligations are fixed; Lay plank 13 at two row's battens, 12 end faces, and with nail that plank 13 is fixing with batten 12, separate the curtain main body thereby constitute.The thick 30mm of batten 12 wide 300mm, the thick 10mm of plank 13 wide 1200mm.
Vertically a derrick fastening devices 2 is installed along separating curtain every 30m.The construction technology of derrick fastening devices 2 is: squeeze into four steel pipes 21 to underground hardpan, constitute the stand of derrick fastening devices, level is laid double-layer pipe 22 on the mud face, 4 every layer, constitute the level frame of derrick fastening devices, be connected and fixed with fastener between stand and the level frame steel pipe, diameter of steel tube is 50mm.
A boundary line plugged the thick color steel 3 of 0.5mm outside act main body was enclosed in the edge separation, and steel plate is inserted dark 2.0～2.2m, exposes mud face 0.8m～1.0m, formed retaining mud and enclosed curtain, the separator bar of formation stabilization zone interior 20 and stabilization zone outer 10; And then enclose an act body edge boundary line and plug layer of plastic film 4 in the inboard of steel plate along separating, form retaining and enclose curtain.
Secondly, carry out the place retaining.
Then, stabilization zone 20 foundation surfaces lay one deck woven cloth 5 and one deck every mud nonwoven 6 to play every mud and security protection effect.
Because the top layer is super soft weak soil, bearing capacity is extremely low, when the constructor carries out every operation thereon, falls into mud easily, exists very big potential safety hazard; In addition, discharge pipe line must separate with the earth under it, avoids mud shutoff drainage channel, to guarantee shallow top layer super soft weak soil generation discharging consolidation under the situation of vacuumizing.Therefore, foundation surface laying one deck woven cloth 5 and one deck can play every mud and safety prevention measure effect every mud nonwoven 6 a little less than ultra-soft, because nonwoven is a loose structure, permeate well can play loaded filter and horizontal drainage cushioning effect in addition.This step also can be omitted, and decides on the job site condition.
As shown in Figure 5, woven cloth 5 laying technologies are as follows: with sewing machine the stick woven cloth is stitched into single-block area by land earlier and is about 3000～5000 square metres of woven cloth, then at the about 0.3～0.5m of stabilization zone 20 place retainings, under the buoyancy of water effect, woven cloth 5 frictional resistance reduce significantly, becoming piece woven cloth one border by 20～50 meters spacing colligation ropes 51, rope 51 by manually applying tractive force 53, becomes piece woven cloth 5 can launch smoothly to lay through assembly pulley 52 (be installed on the derrick device of separating dimension curtain 01 2).After each piece woven cloth laying finished, artificial again stitching waterborne formed an integral body.
As shown in Figure 6, nonwoven 6 laying technologies are as follows: at first at the about 0.3～0.5m of stabilization zone 20 place retainings, every bundle nonwoven 6 is launched and folding being placed on the floating platform 62, tie up on floating platform 62 with two ropes, 61 each end, the other end on the opposite bank, two ropes 61 by artificial traction opposite bank move floating platform 62, and meanwhile nonwoven 6 is laid automatically.Finish artificial stitching nonwoven waterborne behind each stick nonwoven.Floating platform 62 mainly forms with plastic foam, bamboo bar and plank colligation, and floating platform can be regulated size as required.
Then, utilize artificial board plug device 7 to plug the plastic draining short slab, lay the horizontal drainage pipeline, and lay one deck protection nonwoven and one deck sealing film thereon.
As shown in Figure 7, artificial board plug device 7 comprises bar handle 71, U word fork 72, rhombus steel knife 73.The band drain termination is positioned between U word fork 72 and the rhombus steel knife 73, then board plug device is down inserted rapidly, time dead man 71 handles get final product after being inserted into the depthkeeping degree, bar handle length is decided according to the required degree of depth that plugs, and this board plug device has characteristics such as construction is simple and convenient, efficient is high, plastic draining board does not rewind.
The main effect of laying one deck protection nonwoven 91 is to protect the sealing film 92 on it to avoid destroying and causing gas leakage, because nonwoven 91 is a loose structure, permeate well can play the effect of horizontal drainage body in addition.This step also can be omitted, and decides on the concrete condition of job site.
When laying sealing film 92 surface water in the stabilization zone place is drained, diaphragm seal is divided into about 5000～10000 square metres of single-block area, the people stands on the two-layer geotextiles and lays, and is bonding with glue between each piece diaphragm seal.The diaphragm seal film adopts polyethylene sheeting, and thickness is about 0.12～0.14mm, and diaphragm seal is in factory's heat seal one-shot forming, and diaphragm seal is treaded in the mud, treads in the degree of depth and is not less than 1.5m.
At last, connect vaccum-pumping equipment 8, form shallow top layer super soft weak soil bracing means by pipeline.
Select the assembling jet pump systems such as motor of 7.5kw for use, by 1000～1200 square metres of layings of every pump control.Vaccum-pumping equipment should be laid along separating dimension curtain or stabilization zone border, is convenient to safeguard that every equipment is installed on the floating platform in addition that along with water level in the place rises, the foam platform floats automatically, does not influence normally to vacuumize during vacuumizing.Vacuumize fate and decide on super soft weak soil matter, clay and content of colloid grain composition are high more, and permeability is low more, and the pumpdown time is then long more.
(2) the weak native bracing means in described shallow top layer is vacuumized;
Whether unload according to aggregation of data analysis and judgement such as pore pressure dissipation degree during reinforcing and ground settlements.Pumpdown time common visual field ground situation and decide was generally 10～45 days, can suitably increase the pumpdown time for the weakness zone that native water content is too high and transmission coefficient is too small, shallow top layer.
The bearing capacity of the super soft weak soil after step (2) is reinforced can reach 40～60kPa, can hand over, and also can implement to provide execution conditions for the ground integral reinforcing of step (3).
(3) remove sealing film, re-lay the horizontal drainage sand cushion and plug the plastic draining long slab, adopt conventional vacuum method or preloading that ground is carried out integral reinforcing then.
Because the super soft weak soil behind step (2) vacuum pre-press reinforcing reaches certain intensity, can bear the pressure of heavy construction equipment, can satisfy the execution conditions of job practicess such as conventional vacuum method or piling prepressing.
