Technical field
The present invention relates to construction machinery, particularly relate to fluting, paving molding apparatus that the vacuum drainage consolidation for soft base is constructed.
Background technology
In recent years, vacuum preloading consolidation, as a kind of economic, effective soft base processing method, is used widely in reclamation engineering.Conventional vacuum preloading deep layer lateral seal technology mainly adopts mud stirring wall technology, its sealing mechanism is: the soil nature of mud stirring wall is mud mulling, by the mix in proportion of mud and sand, particle reconfigures, glutinous grain is filled to the space between sand, forms the soil that particle is more uneven, grating is good, greatly reduces the transmission coefficient of layer of sand, cut off the contact of permeable (gas) layer inside and outside stabilization zone, made body of wall meet the needs of vacuum preloading lateral seal.
But part coastal area utilizes hydraulic reclamation or Cast-in-situ Piles in Sand-filling to carry out reclaiming land around sea, formed auger ground, on cover special formation condition compared with thick sand bed, or in self-assembling formation soil layer, there is deep burning into sand layer.Due to the existence of above-mentioned highly permeable (gas) layer of sand, after starting to vacuumize, occur liquid phase seepage flow, seepage flow accelerates, and in body of wall, fine grained is easily pulled away, and the lasting impermeability now stirring body of wall reduces, and then affects vacuum pre-press reinforcing effect.
For a difficult problem for above-mentioned deep layer lateral seal technology, be necessary to develop the better Apparatus and method for being beneficial to the construction of vacuum preloading deep layer lateral seal.

Detailed description of the invention
As shown in Fig. 1 ~ 2, for the fluting paving for the construction of deep layer lateral seal of the present invention moulds all-in-one, mainly comprise frame, traveling crawler 1, hydraulic system, grooving mechanism and plastic-laying machine structure.
Frame is used for fixing and supports each parts, and frame is also provided with truss 7.
Described hydraulic system is moulded all-in-one and is provided hydraulic power for synchronous slotting paving, such as grooving mechanism lifting and change angle and power be provided, mould operation for the lifting of plastic-laying machine structure and paving power is provided, power can also be provided for the walking of complete machine.
Described grooving mechanism comprises auger stem 9, hydraulic arm 13, filling system and sand-removing system.Hydraulic arm 13 one end is articulated with the piston rod that auger stem 9 other end is articulated with hydraulic system, stretching by piston rod, changes the luffing angle of hydraulic arm 13 thus the adjustable height of change auger stem 9 and luffing angle.The both sides of auger stem 9 are furnished with circular or square slideway as unit head 14, and unit head can slide up and down along slideway and detachable.Screw socket is adopted to be connected with auger stem under unit head.Can realize vertically advancing of auger stem by unit head, the walking of complete machine drives the level of auger stem to motion.Filling system comprises the grouting port 10, pump for mortar transmission and the feed pipe for mortar 12 that is connected between grouting port 10 and grouting pump that are arranged at auger stem head.Sand-removing system comprises to be taken out stock pump (not shown) and takes out sandpipe 8.Take out sandpipe 8 and be fixed on a cross bar, this cross bar is fixedly connected on truss 7.
Described paving mould structure comprise paving mould reel 4, Double-gear transmission device 5, reel lifting motor 3 and paving mould motor 6.Double-gear transmission device 5 is fixed on truss 7 both sides, and it is made up of two groups of chain and sprocket driving devices, often organizes chain and sprocket driving device and comprises driving wheel, follower and driving rack.Two groups of chain and sprocket driving devices are symmetrically arranged at the both sides that paving moulds reel 4.Often organize chain and sprocket driving device and include driving gear, driven gear and driving rack, wherein driving gear is individually fixed in the bottom of truss 7, and driven gear is individually fixed in the top of truss 7 and is meshed with driving rack.Paving is moulded reel 4 and is fixedly connected on a locating rack 4.1, and the two ends of locating rack 4.1 are fixedly connected on the tooth bar of both sides gear drive respectively.Reel lifting motor 3 drives the driving wheel in two groups of chain and sprocket driving devices to two opposite direction synchronous axial system, thus order about paving mould reel steadily vertically rise or decline.It is hollow cylinder that described paving moulds reel, and geomembrane being collected in winding manner is in cylinder bore, and cylinder barrel offers the slit of outwards unfolding out from cylinder bore for geomembrane, and the initiating terminal of geomembrane has a film initiating terminal fixed bar.When film initiating terminal fixed bar fixedly inserts in after in the soil body, traveling crawler is walked, and paving is moulded motor 6 and driven on one side paving to mould axle in reel and rotates, thus makes paving mould reel rotation, and geomembrane is moulded reel external surface from paving and unfolded and come.
Reel lift motor 3 is hydraulic drive motor, is fixed on the bottom of truss 7.The main oil pipe of reel lift motor 3 is connected with the turnover oil pipe of hydraulic system oil cylinder respectively with oil return pipe.
This synchronous slotting paving is moulded all-in-one constructing operation step and is:
1, primer fluid pressing system, hydraulic oil promotes hydraulic arm 13 through oil cylinder and piston, makes auger stem 9 be positioned at the construction line-putting position and perpendicular to ground, place, starts first guide hole of slotting of constructing.
2, open grouting pump slip casting, the elevation angle of screw drilling rod 9 after design elevation of constructing at construction guide hole simultaneously, make it tilting screw and cut sandy soils.After slot grooving certain length, put into deslagging pump and extract the sandstone falling into groove, control the proportion of mud, prevent collapse hole in work progress, if there is collapse hole to occur, adjustment auger stem angle is stirred again.By circulation slip casting and deslagging, form continuous print groove section.
3, construction about 2 ?start paving after the long one section of groove section of 4m and mould preparation, primer fluid pressing system, the main oil pipe of reel lift motor 3 passes in and out oil pipe with hydraulic arm 13 oil cylinder respectively with oil return pipe and is connected, hydraulic pump is utilized to be transmitted for hydraulic energy the mechanical energy of motor, then being turned by hydraulic energy by reel lift motor 3 returns as mechanical energy, drive the Double-gear transmission device being fixed on truss 7, driving gear drives the paving being fixedly welded on driving rack to mould reel 4 and moves up and down, complete that once paving moulds press down, lifting work.
Reel is pressed in the groove that step 2 digs by Double-gear transmission device, after arriving design elevation, volume film being loosened one section, film initiating terminal fixed bar is inserted slotted eye bottom and fixes, then by spreading the rotation of moulding motor 6, seepage by geo-textile material being unfolded in the mud of paving groove inlet section automatically.After first volume material has been established, lifting single shaft paving is moulded reel 4 and is completed the replacing of new film, press down paving by Double-gear transmission device and mould reel 4, with groove in oldly mould the place that lap length is no less than 2.0m and insert film initiating terminal fixed bar, reel is fixed in slotted eye bottom, completes whole laying work and so forth.As shown in Figure 1a, traction steel wire 2 is moulded reel bottom by the hoist engine be fixed on equipment support and wire rope and paving and is flexibly connected, and moulding in reel press-in groove paving and fixed by wire rope after projected depth, is that it reduces the deflection deformation in traveling process.
4, after completing the Work sectors laying geomembrane, the reserved geomembrane (being no less than 1.0m) exposed is layered in vacuum preloading district, is then in the milk in groove section, precipitate, and the construction that repeatedly circulates.Lay diaphragm seal in vacuum preloading district, diaphragm seal is pasted onto on reserved geomembrane, and treads in certain depth in grooving.
