Now spread concrete when participating in the cintest and surround soft pipe flow guide system
Technical field:
The present invention is that a kind of rugged region of suitable leap of leading is removed the remote honest and clean just durable pipeline to hundred Ф 100 to the Ф 400mm latus rectums as for residential area, family feed flow air feed and set up using method.
Background technique:
How again the conventional pipeline of carrying water or gas is many is embedded in underground forming by iron and steel or concrete prefabricated hard tube, and cost is high and construction is difficult, and connecting port easy to leak, not only wastes but also be easily in danger; This pipeline is easily corroded again and is short-lived.For example the gas ductwork that each household hands over 2,000 yuan of installation fees also to need government subsidy to build is wanted in Guangzhou, only used about ten years and heard again and changed, no wonder all see everyday dig more than.If not too concentrated samll cities and towns of the rugged resident family again of distance are rural area even, this pipeline is more difficult laying just so that vast rural area now still difficulty use tap water and make many ills; More difficult extravagant hope pipeline gas or heated.
And hard tube is easily by bursting by freezing or impaired with foundation deformation, one is dug by mistake and has no buffering and gush to let out, and has many accidents just therefore to give birth to.
Though 200410077216.4 patent applications provide the concept that replaces part hard tube with the soft pipe of growing up, yet applicable be embedded in underground a large amount of in small-bore pipe network.
Summary of the invention:
For overcoming the deficiency of above-mentioned pipeline, the invention provides a kind of Lian Yi and manufacture the soft pipe flow guide system of encirclement of now spreading concrete when participating in the cintest that is easily laid in various landform region.
The present invention solves the technical measures that its technical problem adopts:
1, along the circuit of wanting pipe laying, on ground, dig out tunnel and slightly flatten compacting hole wall and the end, hole, more inferior and can contain the concrete of masonry and make to its upper surface more smooth again without spine more at the end, hole paving one deck.
2, with common needn't the be thick or easy autocratic pipe of scratching soft flexibility, drag it along this tunnel, to launch, and Zhan Shen limit, limit entirely holds some waste and old clothing cloth plastic bag films etc. outside it, and to be formed to thick be approximately 1/300 to 1/100 lamination of pipe outer perimeter, this lamination should be adjacent to soft pipe but unlikely its distortion, with bag, protecting after soft pipe, taking advantage of a situation and lie in that above concrete layer having solidified.
3, allow each port of this section of soft pipe all be connected with adjacent members, then manage the soft pipe of inflation as far as possible but few dilatancy.
4, the outer injection compared with high-quality and containing the concrete of pressing the soft pipe of thorn to be out of shape of soft pipe that keeps inflation at this, forms suitable thickness outward to the soft pipe of total incapsulation.After solidifying, add again conventional concrete [can contain masonry], to solidifying, reach the i.e. success of intensity of pressing in enough expansions.
Beneficial effect of the present invention is:
1, low cost easily construction again---be first soft Guan Changlian in hard tube [being iron pipe especially], and all branchiess any paragraphs are as long as rationally choose trend, avoid anxious complications curved, just can entirely exempt from the mouth of pipe of plugging into, and even entirely exempt from hard parts.Only along the ditch soft pipe of cloth of lying.This makes the larger saving again of accessory and operating expenses, can offset the cost of multiplex that common more honest and cleaner concrete completely and have a surplus.If adapted autocracy many take less by cheap glass fibre looping, plastic cement is more tough to be thinly suitable for disposable expansion and to set the soft pipe of no longer displacement and just more saved cost.For example supplied the Ф 400mm of ten thousand family waters to grow the soft pipe of 200 meters, internal layer is made by thick about 0.5mm high-quality plastics, approximately 3 tons of weights only after the sticky glass fibre of outsourcing and at a low price plastic cement binding, have winch or tractor to coordinate its along the line laying to can be jointless in 200 meters of easily carrying, and it is convenient as seen.What diameter was thinner just more easily does.
2, being especially suitable for rural area geology landform complicated and changeable leads safely thin---and be first to hold soft Guan Yin to have and must go along with sb. to guard him by more tough glass fibre, Yi Lingrou pipe dilates that to split the curved hard tube being welded into of the equal iron plate of force rate higher; Outside holding concurrently, there is concrete to surround just stronger.Can give full play to the effective capacity of materials.When running into foundation deformation or being dug by mistake, obviously than hard tube, there is much better than expansion to damage ability.While firmly invaded by external force because of soft pipe again, must contract to keep away and be difficult for breaking; And it is outer adds again the bags such as duds thing waste plastics and protects and can exempt from and concrete layer adhesion [certainly easier by demand, cause adhesion], even if concrete layer is by extremely fracture of earth mover pick [if mistake pick, allowed already pick person's vigilance], this soft pipe is not easily followed concrete fission entirely yet, has telescopic resilience with soft anti-broken.This performance has more obviously been better than hard tube in the wilderness of rugged fluctuating, and soft pipe is not afraid of severe cold bursting by freezing.
3, can reduce the mutual corrosion between pipeline and contained fluid---the few joint of first soft pipe, can make fluid only contact with pipe internal surface to subtract with other object contact to cause complicated bad reaction to greatest extent.Just so again this fluid of the Yi Zaorou pipe ad hoc Cheng Buyu in inner surface layer produces bad reaction, and needn't be subject to tying down of other performance requirement.Realize specially material special use, ensure the purity of institute's deflector, increase again pipeline life and subtract leakage loss.
4, multi-functional---it both can be used for mountain village, also can be used for big city; Both can send benefit stream here, also can drain dirty stream; And be not afraid of general earthquake or floods; Also anti-erosion; Also extremely should develop into thicker going helps the south water to north, western gas east to send or even introduce the Engineering Service of Russia's rock gas.Formed concrete upper surface also can double as the guide rail of road or ridge or even following new-type machinery.
Accompanying drawing explanation:
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 surrounds soft pipe flow guide system and has installed into the water supply of a straight section Shallow-Embedded Under-Ground or gas pipeline along its tubular axis line place vertical guide cross-sectional schematic according to provided by the invention now spreading concrete when participating in the cintest, and Fig. 2 is that the A-A of Fig. 1 is to sectional view.
In figure: 1, carry out source capsule; 2, strangle hoop; 3, soft pipe; 4, base concrete; 5, all concrete; 6, guard beam; 7, upper concrete; 8, backfill; 9, pipe joint; 10, add and twine layer; 11, ground.
Embodiment:
As shown: allow the extraneous pipeline of supplying with user's water of the present invention or gas only expose a bit of and process or mix suitable rigidity and come source capsule 1 as port, be placed on the port of source capsule 1 to form connecting tube form outward the strong equal of head end of soft pipe 3 to be buried underground again, and strangle hoop 2 jails to not leaking.Along setting path, 11 dig out width than more than the wide 5cm of going out of this soft pipe 3 and " U " tee section ditch of dark approximately 1 meter earthward again, again along this bottom of trench paving fill with cheap base concrete 4 that approximately several cm thicks of thick layer needn't high-quality and its upper surface make to without point protruding try one's best smooth; After it solidifies, launch soft pipe 3 and twine layer 10 in its additional even folded close adding of discharge value of but not strangling the soft pipe 3 of change to approximately several millimeters thick as far as possible that twines waste and old clothing cloth plastic bag film and so on; Limit adds wrapped edge and takes advantage of a situation these Guan Fangzhi ditch central authorities are located immediately.
To being filled with suitable water in this soft pipe 3 to sealed against leakage after making soft Guan Quan bulge, just can outside it, spread all concrete 5 of filling with even and fine compared with high-quality again.This paving in filling with, must keep as far as possible soft pipe 3 locate and manage in sectional area try one's best small deformation [this easy-regulating interior water content of soft pipe 3 and pressure fitted successively suitably intermittently the height of all concrete 5 of paving filling reach].Allow the upper surface paving of all concrete 5 to grasping depending on live apart from soft pipe 3 tops approximately 5 to 15cm[] and solidify after, surface is put larger Iron And Steel Scrap or the old building of some Length Ratios " U " shape ditch width and is pulled down into the stronger native stone of piece as guard beam 6 thereon, and pouring upper concrete seven is to entirely covering guard beam 6 and can preventing damaging by pressure again.After solidifying, insert backfill 8 and completed the laying of this section of soft pipe 3 to putting down in 11 of original grounds.Because this soft pipe 3 easily causes, grew hundred meters of rolling, length of run can be any, and this tail end that does not launch still rolling up is very easily clamped to and does not leak again, and discharging amount easily chooses at random deacclimatizes the length of successively excavating pipe laying, to subtract, hinder land operations.
If this ground 11, place needs sclerosis, can estimate " U " shape ditch depth, on relief, concrete seven upper surface is put down in ground 11 and can have been saved backfill 8.Even allow on this concrete seven upper surface just more save trouble as road surface etc.And be less than 20cm for buried soft pipe 3 diameters, guard beam 6 also can have been economized.
When this section (volume) soft pipe 3 is to the greatest extent or when bifurcated answered by pipeline, can allow the tail end of this soft pipe 3 be tightly placed in that prefabricated supporting pipe joint 9 is outer and to strangle hoop 2 firm.This pipe joint 9 can cause similar town gas three form of pipe joint again, and prewired multiple applicable specification and not only have trident, also should have spider or two logical various ways; With just very easily allow soft pipe 3 arbitrarily be communicated with other any recanalization.Adopted the recanalization place of pipe joint 9 or alternate manner equally easily to add to protect with coagulation mount, just for rigid member is wherein easy to dismounting or repacking in the future, should be first in its appearance, has also wrapped to add and twine layer 10 and contact and be advisable with concrete again.One has to add and twines layer and 10 separate, and the concrete of hard parts outsourcing is when the time comes just easily by cutter stripping.And will chisel bag, be fixed in concrete [first watering Waste Sulfuric Acid easier] outside soft pipe 3 and at middle segment, therefrom add inserting again and refute new pipe joint 9 and in the stage casing of this soft pipe 3, reequip to increase and join branch road, must than to take apart hard tube that routine can only install and remove in order reequip again convenient.Visible the present invention is also stronger to the flexibility of adaptation social development resident transition.Until this pipe network as after being communicated with as routine can work.Soft pipe 3 also can be embedded among the concrete structure of other road surface, terrace or building as stated above so as to surrounding, and subtracts the ad hoc concrete consumption of assuring.
This soft pipe 3 easily causes again nonconducting, even if buried, during side's its water-filling leak detection, easily by commonly using resistance measurement instrument etc., predicts leak source; Section again wherein and can Lian Yi to add rapidly pipe-fitting joint 9 and so on and repair.If establish again the intensity of attached increasing people guard beam 6 and the support force of below thereof, can establish thicker soft pipe 3.
For better reaching object of the present invention, should accomplish: allow flexible or flexible long tube put into the hole that ground pick is opened as far as possible, the concrete that allows again this soft pipe be injected into hole under the state of inflation is surrounded, the soft pipe bulging until this concrete around congeals into after integral body, can replace the common underground rigid conduit that is laid on.By soft plastic, cause length to be greater than 30 meters, diameter is no less than the soft pipe 3 that 10cm, wall thickness be greater than 0.2 millimeter and puts into the hole that ground excavates, and by concrete grout, is surrounded under the state of inflation.This soft pipe 3 contains the pressure of fluid than the large 0.5kg/cm of the pressure of extratubal fluid
2after surround being surpassed 24 hours by concrete grout when above, just allow pressure reduction in soft pipe 3.Soft pipe 3 concrete thickness is around greater than 2cm, and the top of this soft pipe 3 be provided with across guard beam 6.
