The joint includes a rigid cylindrical portion and a cylindrical flexible portion that has a covering portion to be fixed around an outer periphery of said pipe, a fixing portion fixed to an outer periphery of said rigid cylindrical portion and to be fixed to the manhole and a connecting portion connecting the covering portion to the fixing portion and made of an elastic material being capable of absorbing a displacement between the manhole and the pipe. The waterproof flexible joint is located around the outer periphery of the pipe, and the covering portion is fixed around the outer periphery of the pipe. Then, a filler for the manhole is poured around an outer periphery of the fixing portion.
Description
Technical field
The present invention about manhole structure's job practices, manhole structure with waterproof flexible joint and manhole structure.
Background technology
The job practices of pipe has by excavation and the job practices of backfill and, propelling construction method etc.The propelling construction method is at first to excavate two shafts (shaft) that advance and arrive, and secondly, utilizes jack flatly to release sewer pipe from advancing the hole beginning, utilizes level to bore control mechanical equivalent of light excavation lateral aperture simultaneously.
Fig. 4 is known manhole structure's 41 a skiagraph.As shown in Figure 4, manhole 42 is laid in the vertical core.The retaining wall of the occasion of excavation shaft generally is to use steel pipe for keeping minimum job area.When the constructing of manhole, its sleeve (casing) steel pipe becomes outboard template 44, and between the inner side template 45, forms manhole 42.
When this shaft was constructed manhole 42, the pipe 43 of the sewer pipe that lays earlier etc. was the relation that the space is set because of manhole 42, imbeds in people's hole wall portion concrete 46.
And as shown in Figure 4, the interface 47 of pipe 43 and people's hole wall portion concrete 46 becomes the relation of the waterway that leaks easily, and is good with adhering to of pipe 43 for making concrete 46, for the purpose of preventing to leak, uses the attached sand short tube that adheres to sand 48 at the outer peripheral face 43a that manages 43.
The problem that the invention desire solves
Manhole structure shown in Figure 4 41, concrete 46 is to become rigidity in conjunction with (rigid joint) with combining of pipe 43, and when earthquake etc., pipe 43 has damaged possibility.Especially, pipe 43 is the occasion of Hume's pipe (Hume concrete pipe) or earthen-ware pipe etc., the breakage by the domain displacement easily.
Pipe 3 be the occasion of the flexibility pipe of resin etc., though cause that by the domain displacement possibility of breakage is lower, still have high breakage possibility.And pitch tube is in succession in concrete, easily given birth to waterway during need not be attached husky short tube, and its sealing has problem.
Attached sand short tube is sunk and can be produced minim gap 49 etc. in the bottom of pipe 43 by the presclerotic dehydration of concrete 46 as shown in Figure 4, or after the several years, meeting is shunk because of the drying of concrete 46 and produced minim gap 49 etc., thereby leaks.
At the flexibility pipe of pitch tube etc., special, because flexual relation, it is flat by soil pressure etc. pipe to be become, though with attached sand short tube, can not get rid of the generation of waterway fully.
Summary of the invention
Problem of the present invention is to make manhole and pipe become softness by the manhole structure with waterproof flexible joint to combine (flexible joint), when earthquake etc., can prevent the breakage of pipe.
And problem of the present invention is that leaking between manhole and the pipe prevented fully.
The present invention is about manhole structure's job practices, be applicable to manhole is connected with pipe, comprise: producer's pore structure waterproof flexible joint, above-mentioned manhole structure has the body of scratching of the cylindrical body of rigidity and tubular with the waterproof flexible joint cording, above-mentioned tubular flexible body has the covering part of the periphery that is fixed in aforementioned tube, be fixed in the fixed part of above-mentioned manhole and make above-mentioned covering part and the linking part of said fixing portion binding, the periphery of above-mentioned cylindrical body is fixed in said fixing portion, above-mentioned linking part is formed by the elastic body that can absorb the displacement between above-mentioned manhole and the aforementioned tube, make above-mentioned manhole structure use water flexibility joint arrangement in the periphery of aforementioned tube, make above-mentioned covering part be fixed in the periphery of this pipe, pour into a mould the manhole filler in the periphery of said fixing portion.
And, the manhole structure of the present invention about making with waterproof flexible joint and above-mentioned construction method in above-mentioned construction method end user pore structure.
Knowledge Base of the present invention can make the pipe of propelling construction method become the soft manhole structure who combines with on-the-spot junction surface of watering the manhole of the concrete system of putting by by using fixed manhole structure to use waterproof flexible joint.
Have manhole, pipe and manhole structure in inventor's pore structure and use waterproof flexible joint, by the periphery at pipe make the manhole structure with waterproof flexible connect fixed after, constructed with filler with the outside of waterproof flexible joint cast manhole the manhole structure.
The cylindrical body and the tubular flexible body that possess rigidity about manhole structure of the present invention with waterproof flexible joint.The cylindrical body of rigidity is disposed at the radial outside of tubular flexible body, has the effect that makes tubular flexible body be fixed in manhole.
Have the covering part of the periphery that is fixed in pipe about tubular flexible body of the present invention, be fixed in the fixed part of manhole and make covering part and linking part that fixed part links.
Be fixed in the periphery of the cylindrical body of rigidity about the fixed part of tubular flexible body of the present invention.The tubular of this rigidity is to make the fixed part of tubular flexible body be fixed to manhole.
In the present invention, make the covering part of tubular flexible body be fixed in the periphery of pipe, in the periphery of the fixed part of tubular flexible body, cast manhole filler is to apply Access Opening's structure.
In the present invention, manhole comprises with filler and is poured in order to the concrete in the template of construction people wall surface of the hole at the scene or is fills up to the hole face of cutting that is formed on people's wall surface of the hole such as the vertical manhole of group, and between the flexibility joint, use so that the manhole structure is fixed to the filler of cutting the hole face with waterproof flexible joint.
About tubular flexible body of the present invention, its linking part is formed by the elastic body that absorbs the displacement between manhole and the pipe.This linking part has the effect that absorbs the displacement between these between manhole and pipe.
About rigid column of the present invention is when the periphery cast manhole of the fixed part of tubular flexible body use filler, has the fixed part of support tubular flexible body, makes this fixed part be fixed in the effect of manhole.
And, tie up between the fixed part of tubular flexible body and the covering part about rigid column of the present invention and to guarantee the space, in this space, the linking part of tubular flexible body absorbs the displacement between manhole and the pipe.
According to the present invention, after the periphery of pipe makes the manhole structure fix with waterproof flexible joint, by the manhole structure with the periphery of waterproof flexible joint, manhole is poured into a mould with filler, can the utmost point apply the manhole structure who makes the tool manhole efficiently and combine with the flexibility of pipe.
