Description
CROSS-REFERENCE TO RELATED PATENT
The application requires the preference of the korean patent application No.10-2006-0115275 that submitted in Korea S Department of Intellectual Property on November 21st, 2006, and its content is drawn in this integral body and is reference.
Technical field
The present invention relates to a kind of manhole (manhole) and pipeline composite structure, it can change the pipeline direction, and more particularly, relate to a kind of manhole and pipeline composite structure that can change the pipeline direction, it has the serviceability of the height of opposing external force, prevent moving of pipeline, have the operability of height, and particularly importantly can prevent to leak.
Background technique
Manhole is made different shape and is used for using, for example square or oval.Yet usually, circular manhole uses at most, because it is conveniently made and has a tight security.Manhole use concrete material manufactures the cylindrical shape of hollow, approximately tens of centimetres of general diameters.Manhole is covered by the circular lid that the concrete of cast iron or reinforcement forms.The bottom that the bottom of manhole forms with pipeline is on the equal height, perhaps by tractive slightly downwards to hold sludge.On the contrary, consider mobile directivity, the bottom that is used to place the manhole of sewage conduct or addle pipeline can form the bottom that is higher than pipeline slightly.
Though have multiple difference between various situations, manhole generally includes a plurality of pipeline connection opening, and described opening radially is formed on the sidepiece of manhole main body, to admit an end of each pipeline.In order to use, at the manhole that is used for addle or sewage, waste pipe is connected to the pipeline connection opening, and described connection opening is formed on the sidewall of manhole main body.Yet manhole is mainly formed by concrete material, and pipeline is made by metal or nonmetal (PVC, PE etc.).Therefore, the material of manhole and pipeline differs from one another.In this respect, importantly guarantee between manhole main body and the pipeline waterproof, thereby the addle or the sewage that flow in pipeline can not revealed.
Below with reference to Figure 12-17 common manhole-pipeline composite structure and problem thereof described.
Manhole shown in Figure 12-pipeline composite structure is used the combination force of solidifying and hardening according to concrete 10 or mortar.In manhole main body 100, get out a plurality of holes, to form pipeline connection opening 110.The top hole is from 110 radial locations of pipeline connection opening.Usually, pipeline connection opening 110 has circular cross section, and forms in such a way, and promptly its internal diameter reduces gradually towards the inside of manhole main body 100.That is to say that pipeline connection opening 110 is tapered towards the inside of manhole.After pipeline 200 inserted in the rubber ring 300, an end of pipeline 200 inserted in the pipeline connection opening 110 securely.Rubber ring 300 is pulled in the end of pipeline connection opening 110, thereby rubber ring 300 inserts in pipeline connection opening 110 and the pipeline 200.Then, elastic force helps compressing between pipeline connection opening 110 and the pipeline 200, thereby at first guarantees waterproof.When plastics fixed support device 400 is positioned and concrete 10 when being placed between manhole main body 100 and the plastics fixed support device 400, concrete 10 sclerosis, thus pipeline 200 and manhole main body 100 are connected to each other, thus guarantee waterproof auxiliaryly.
Because above-mentioned manhole-pipeline composite structure has heavily stressed concrete, so it can fully resist external force.Yet,, therefore need long man-hour and very high cost because it need be placed on the original place with concrete 10.In addition, because the elasticity coefficient of rubber ring 300 (expansion coefficient) is different with concrete 10, so the connection power between rubber ring 300 and the concrete 10 is so not high.In addition, because the combinations thereof structure has been used the method on the sidepiece that in addition other concrete 10 is connected the manhole main body 100 that concrete material makes, so the combination force of concrete 10 and 100 is not high, unless use other sealing material (not shown).That is to say that the concrete 10 of filling may be from manhole main body 100 separately.
In addition, when placing concrete, the position of pipeline can change, thereby concrete not exclusively solidifies, and therefore can produce defective in structure.When not constructing accurately, can not guarantee waterproof.
Figure 13 shows another kind of common manhole-pipeline composite structure.The feature of this structure is that pipeline 200 and manhole main body 100 form each other in integral body when manhole main body 100 is manufactured.
This structure has solved the part in the problems referred to above (i.e. Xia Mian problem: fill concrete is not connected to the manhole main body, and owing to place concrete temporal differences, partially or completely breaks away from from the manhole main body).Pipeline 200 inserts in the rubber rings 301 with another that guarantee fluid-tight this structure and is characterised in that rubber ring 301 is hydrophily (hydrophillic) rubber rings, and expansion that described rubber ring is repeated or contraction depend on whether contact with water.When manhole main body 100 is mounted and hydrophily rubber ring 301 when expanding by contacting with water, the reinforcing that the expansion of rubber ring 301 causes has been guaranteed between pipeline 200 and the manhole main body 100 waterproof.
Yet because 301 reexpansions of hydrophily rubber ring and contraction, therefore, the gap between pipeline 200 and the manhole main body 100 is broadened, and water is revealed by described gap.
Figure 14 shows another kind of common manhole-pipeline composite structure.This structure has been used connecting element (auxiliary device) 510 and linkage unit 520 and 530 in addition.Linkage unit is the bolt 520 that combines and fastens (anchor) nut 530.
Connecting element 510 has " [" shape section, and comprise the open pores (not shown) usually.Open pores is formed on the plat surface of connecting element 510, and has the internal diameter identical with the external diameter of pipeline, thereby pipeline inserts in the described open pores.End 111 is formed on pipeline connection opening 110 places of manhole main body 100, and a plurality of anchor bolt 530 be placed on end 111 below, thereby be fixed to pipeline connection opening 110.
In this structure, after the open pores of described connecting element 510 is passed in pipeline 200 insertions, pipeline 200 inserts to be fixed to pipeline connection opening 110, and bolt 520 inserts and passes the connection hole (not shown) that is formed on the connecting element 510, thereby bolt 520 and anchor bolt 530 are connected to each other, thereby pipeline 200 and manhole main body 100 are linked together.
Reference character " 302 " expression hydrophily rubber ring, it is identical with above-mentioned hydrophily rubber ring 301.
According to the combinations thereof method, not slight when mobile by external force when the pipeline 200 that combines with manhole main body 100, sewage can not revealed.In addition, because the connection power between pipeline 200 and the manhole main body 100 is relatively very high, so serviceability and the reliability height that prevents to leak.
Yet, when manhole main body 100 or pipeline 200 since around be embedded with manhole main body 100 ground differential settlement or because external force and slight when mobile, because the major part of manhole main body 100 load concentrates on connecting element 510 and/or linkage unit 520 and 530, therefore coupled condition becomes lax, and restraining force reduces.As a result, between manhole main body 100 and pipeline 200, produce the gap, leak thereby cause.Because pipeline 200 and manhole main body 100 be only by using linkage unit 520 and 530 and connecting element 510 and structurally combining, therefore for the unusual static load of low-load, composite structure is durable.Yet, do the time spent when being subjected to dynamic load, connection power reduces, and therefore water is revealed.
Figure 15 shows another kind of common manhole-pipeline composite structure.This composite structure used serum cap 540 and two auxiliary be with 550 and 560.Serum cap 540 is fixed to the inboard of pipeline connection opening 110, and is water-tight to guarantee.A pair of subband 550 and 560 is used for serum cap 540 is expressed to pipeline connection opening 110 and pipeline 200.
After serum cap 540 inserted in the pipeline connection opening 110, the rotary unit 551 of subband 550 was rotated so that serum cap 540 is expressed to pipeline connection opening 110, shown in Figure 15 and 16.Concrete is, when bar bolt 552 rotations of subband 550, trip ring 553 expands, thereby serum cap 540 is extruded to pipeline connection opening 110.The helical thread portion (not shown) is formed on the whole outer surface of bar bolt 552, and rotary unit 551 is positioned in the intermediate portion of bar bolt 552.Bar bolt 552 is connected by support device 554 with ring 553.Each support device 554 is fixedly attached to ring 553.On support device 554, get out the tapped hole (not shown), thereby bar bolt 552 inserts when rotation.The helical thread portion (not shown) is formed in the tapped hole, and described helical thread portion is identical with the helical thread portion that forms on the outer surface of bar bolt 552.According to this structure, the rotary unit 551 that keeps by the hand by the user when bar bolt 552 is during along any direction rotation, and support device 554 and encircles 553 open part 559 broad that becomes gradually away from each other, expands thereby encircle 553.
By using described subband 550, the front end of serum cap 540 is fixed and is expressed to the inboard of pipeline connection opening 110, and the other end of serum cap 540 is extruded to pipeline 200 by using another subband 560.Subband 560 has the driving principle identical with subband 550, thereby but is used for connecting described ring by described ring is shunk.Different with subband 550, in subband 560, a pair of support device 564 forms towards the outside of ring 563 outstanding.Bolt 562 is connected to nut 561 by the tapped hole (not shown), and described tapped hole is formed in the support device 564.Link to each other because bolt 562 inserts in the nuts 561 and with nut 561, thus any other helical thread portion can not be formed in the tapped hole of support device 564 be formed on screw rod 562 on the helical thread portion (not shown) corresponding.According to this structure, when screw rod 562 rotation, support device 564 becomes more gradually near each other, and therefore, ring 563 shrinks, thereby the other end of serum cap 540 is extruded to pipeline 200.
Yet this connection is to carry out at the scene, and is identical with the concrete composite structure of above-mentioned use.Therefore engineering is complicated, and is being disadvantageous aspect man-hour and the cost.In addition, as shown in figure 17, when ring 553 when in subband 550, expanding, the open part of ring 553, i.e. two of open part ends 559, the interior curve towards ring 553 causes shape to deform.By this distortion, serum cap 540 is spaced apart with pipeline connection opening 110, and water is revealed by described space.
As mentioned above, because common manhole-pipeline composite structure can not be attached to gratifying level with manhole and pipeline, so they have many problems.
In addition, in common manhole, lid is placed on the top of manhole main body.Yet, because lid is remained on the top of manhole main body simply, do not utilize any special linkage unit, thus lid can by external force from the manhole body portion from.
