Abstract
A splitter with arc plate is attached to pipe of vibration-type pipe sinking machine. Under action of pipe sinking machine, said splitter is sunk underground to split earth to form slot. The mortar is poured into arc slot via holes at head of pipe and grouting holes of splitter by mortar pump. Continuous construction can form an enclosed and continuous water-stop curtain.
Description
The invention belongs to the job practices and the equipment thereof of building foundation deep-foundation pit engineering.Deep pit digging blocks water; keep off native dirty Foundation Design; it is in the formation all around of the intending deep pit excavation case type curtain that blocks water of chain one-tenth together; stop underground water in foundation ditch, to infiltrate; to guarantee the dried operation of foundation construction; can stablize the outer underground water level of curtain again, make it to protect the safety of Foundation Design existing building thing on every side.
At present known domestic and international deep pit digging retaining soil, block water, seepage control technique all adopts underground reinforced concrete diaphragm wall, steel bar concrete is stake, deep mixing method and high-pressure rotary spraying method and grouting etc. continuously.All there is the construction costs height to some extent in said method, needs to use material various, and is technical strong, and complex process equipment, situation long in time limit.For example, adopt steel bar concrete diaphragm wall method, it is intended to adopt on the ground a kind of trench machine, periphery along basic deep excavation project, rely on mud off, excavate out a long and narrow deep trouth, and in groove, hang into reinforcing cage, use the tremie method underwater concreting with tremie method with displacement mud then, build up a unit groove section.Carry out so piecemeal,, build up continuous steel concrete wall one underground with certain joint style, in order to intercept water, antiseepage, load-bearing, retaining soil.There are the following problems for this job practices: the one, need more special-purpose machines and tools and equipment; The 2nd, construction technology is comparatively complicated, and need have certain technical level; The 3rd, bad if construction technology is grasped, be easy to occur the hole of collapsing, the concrete sandwich leakage problems also need have the management method of the mud off that is fit to different geological conditionss, and handles the measures that will take when breaking down etc.
Purpose of the present invention is to provide a kind of foundation pit construction easy, duration weak point, dependable performance, also suitable building compact district, and soil property is that the deep pit digging of viscosity, grittiness ground blocks water, anti-splitting grouting and water-proof curtain construction method and the equipment that blends retaining soil.
Splitting grouting and water-proof curtain construction method of the present invention is: the immersed tube that adopts special vibrating immersed tube machine will have the arc splitter is learned into underground, soil body splitting is become the second-degree parabola deep-slotted chip breaker, utilize mortar pump by immersed tube sink into in the vibration carried, small opening and the splitter both sides injected hole of lean concrete grout by the immersed tube head injected in the deep-slotted chip breaker, form the arc board wall, after constructing continuously, the curtain that blocks water of chain one-tenth sealing.
A kind of equipment that is used for above-mentioned job practices: utilize the arc splitter is set on immersed tube, the cross section is the second-degree parabola shape, with soil body splitting grooving, has the injected hole with the mutual vertical conducting of immersed tube inner chamber on the diagonal of splitter.
The present invention draws than having following advantage with prior art:
1, process is simple.Adopt splitter with soil body splitting grooving.Splitter sink into on propose once grouting moulding simultaneously, avoided the job practices of manufacturability such as existing steel bar concrete diaphragm wall, technical complexity.
2, impervious effective.It is 4 * 10 that number is adopted in the splitting grouting and water-proof curtain infiltration
-9Below the cm/s, and steel bar concrete diaphragm wall transmission coefficient 2 * 10
-4-2 * 10
-8Cm/s.
3, the construction period is short.The splitting grouting and water-proof curtain duration only accounts for 30% of the steel bar concrete construction of diaphragm wall phase.
4, cost is low.Splitting grouting and water-proof curtain reduces expense 58,76% than steel bar concrete diaphragm wall.
5, structural mechanical property is reasonable.Splitter adopts the second-degree parabola form, and second moment of area is big, and arch structure is stressed based on axial force, with the stake curtain integrated structure of soldier pile combining form.
Description of drawings:
Fig. 1 is splitter partial structurtes schematic diagrames.
Fig. 2 is the curtain wall schematic diagram.
Fig. 3 is the schematic diagram of stake curtain combination.
To do concrete description to the job practices and the equipment of splitting grouting and water-proof curtain of the present invention:
The soil body supporting curtain wall on slope is put in utilization, before the curtain construction, along the deep excavation project periphery, adopt shaping equipment DZ-40Y type exciting force 330KH vibration sinking tube machine, see Fig. 1, utilize on immersed tube, to be provided with the arc splitter is installed, its cross section is the second-degree parabola shape, underground in order to sink to, with soil body splitting grooving, and the injected hole that has on the diagonal of splitter with the mutual vertical connection of inner chamber of immersed tube is used for injecting slurries in groove.When foundation ditch allows to put the slope, the soil body supporting curtain wall on slope is put in the curtain utilization, the periphery of heavy deep excavation project, adopt the vibration sinking tube machine, the immersed tube that will have the arc splitter sinks to underground, because of the cross section of arc splitter is the second-degree parabola shape, soil body splitting is become thick 60mm, the second-degree parabola arcuate furrow of wide 900mm, by 100/15 molding sand stock pump (flow 100L/mm, pressure 15kg/cm) cement paste is injected in the immersed tube, immersed tube sink into in the vibration carried, lean concrete grout is injected lean concrete grout in the arcuate furrow by the small opening of immersed tube head and the injected hole of splitter both sides, it is thick to form 700mm after the slip casing by pressure, be second-degree parabola arc cement wall, (y=4fx(l-x)/l
2, chord length l=900mm, rise f=0.2, l=180mm, wall thickness s=70mm) and the curtain that blocks water of the chain one-tenth sealing in construction back is seen Fig. 2 continuously in certain sequence.
Fig. 3 is the embodiment of stake curtain associated methods.Utilize lagging pile supporting curtain (opposing lateral pressure), before the curtain construction, pile crown A side (A is that the outside, B are for inboard) is excavated to certain depth, slip casting splitter 2 two side ends are pressed close to after an a, the b point, slip casting splitter 2 avales, by mortar pump cement is injected in the immersed tube 1 equally, utilize immersed tube 1 sink into in the vibration carried, respectively the small opening of lean concrete grout by immersed tube 1 head and splitter 2 injected in the arcuate furrow.And block water, keep off soil and antiseepage by the sealing of the chain one-tenth of the order between stake.
