In the elastic body material therefor, special preferred rubber.Because this material of rubber itself has elasticity, can stretch, to the displacement of pipe, be suitable for bringing into play its tracing ability.
Water the partition wall of people's hole wall usefulness filler into when cylindrical body of the present invention can be used as in-situ casting, between cylindrical body and pipe, guarantee the space that the tubular flexible body is required.Therefore, this cylindrical body preferably can be out of shape because of the pressure of casting concrete etc.
In the present invention, can use and manage the cylindrical body of same material.But in the manhole structure 41 in past shown in Figure 13, the pipe 43 of sewer pipe and so on becomes the passage that leaks easily with the interface of people's hole wall 44.
Figure 14 is the front view of the manhole structure in finding past in the vertical shaft.As Figure 13 and shown in Figure 14, among the manhole structure 41 in the past, because dehydration is sunk and in cylindrical body gap that the bottom produces in the course of hardening, with after the several years, shrink reasons such as producing minim gap 47 owing to concrete is dry, the interface place with people's hole wall 44 leaks easily at sewer pipe and so on pipe 43.
Therefore, use in cylindrical body of the present invention under the situation with the identical material short tube of pipe, the attached sand short tube that can use outer peripheral face to be stained with sand makes cylindrical body surface and people's hole wall with adhering between the filler well.
In cylindrical body of the present invention, people's hole wall made from concrete etc. can be attached to the tubular dignity that contacts with filler with the people's hole wall that constitutes people's hole wall with bonding bonding material or the bonding material of filler.
Described bonding material or bonding material can adopt water-expansible rubber class bonding material or the bonding material of non-vulcanization butyl rubber (butyl rubber) class.
And, the bonding material of the preferred non-vulcanization butyl rubber-like of described bonding material or bonding material.Water-expansible rubber class bonding material sucks and immerses water and expand, with its turgor pressure sealing, butyl rubber be bonding material then in the process of people's hole wall with the filler sclerosis, and people's hole wall is with chemical adhesive between the filler, sealing is higher.
Described bonding material or bonding material can prevent owing to people's hole wall produces leaking that the gap causes with sinking to the cylindrical body bottom under the dehydration before the filler sclerosis, also can prevent because shrink the generation minim gap and leaking of causing through people's hole wall for many years with filler is dry.
Cylindrical body periphery of the present invention can be installed a bead (flange).This bead is goed deep into people's hole wall filler of people's hole wall, helps to make cylindrical body to be fixed in the concrete of people's hole wall, the compactness of people's hole wall of lifting cylindrical body and people's hole wall between the filler.
People's hole wall that described bead is goed deep into people's hole wall is with in the filler, as long as it can not have special restriction to its material at people's hole wall with fixing in the filler, and preferred being difficult for because of casting the material that people's hole wall is out of shape with the pressure of filler.
And the face that people's hole wall of people's hole wall that bead of the present invention and concrete etc. are made contacts with filler and the above-mentioned cylindrical body and the contact surface of people's hole wall can and attach with filler bonding bonding material or bonding material with people's hole wall equally.
Described bonding material or bonding material can use above-mentioned water-expansible rubber class bonding material or the bonding material of non-vulcanization butyl rubber-like, preferably use the bonding material of non-vulcanization butyl rubber-like.
Described manhole structure comprises the cylindrical body with above-mentioned bead structure with flexible water-stopping joint, and be pasted with bonding material or bonding material in its outside, the bonding material of described bead and cylindrical body periphery or bonding material attach, and people's hole wall of imbedding people's hole wall is used in the filler, can interdict the immersion of going between people's hole wall and cylindrical body, can prevent fully from people's hole wall leaking with the interface of filler.
And, in Japanese patent laid-open 9-32020 communique (JP-A-9-32020), described a kind of manhole structure and used flexible water-stopping joint.Figure 15 is to use the skiagraph of one of this flexibility water-stopping joint example.This flexibility water-stopping joint 301 is pressed and fixed on cutting on the face 302a of hole of manhole 302 to an end 301a of the flexible joint 301 of rubber system with spreading belt 303, to cover the periphery of sewer pipe 304.Be fixed on the pipe 304 by the other end 301b of rubber system flexible joint 301 is right after crimping with tight ligament 305, make the manhole 302 and the junction surface of sewer pipe 304 become flexible structure, guarantee sealing simultaneously.
Described manhole structure, should be installed on the manhole before managing in succession in advance with flexible water-stopping joint.
When manhole is during at produce in factory, the hole of inserting sewer pipe and so on pipe is to process with the assigned address of concrete drilling machine at manhole.Cut the hole face though rubber system flexible portion is pressed to be fixed on by spreading belt, it is not necessarily smooth and smooth to cut the hole face.
The drill bit position of concrete drilling machine is embedded with diamond, machinable cement mortar and aggregate.But the vibration in drilling machine when work can produce uneven about 2～3mm, and especially, when improving when changeing hole speed, it is big that concavo-convex fluctuating becomes.Concrete itself contains some bubbles in addition, and this also becomes concavo-convex reason.As shown in figure 16, Figure 15 is the partial enlarged drawing of Figure 16, leaking between the described uneven end 301a who causes cutting hole face 302a and flexible joint 301 easily who cuts the hole face.
Therefore, rubber system flexible portion must have certain rigidity, and must be the rubber of not creep (creep) because its be pressed and fixed on by spreading belt that manhole cuts on the face of hole should sealing, can absorb displacement simultaneously watertight again.
But, adopting this kind elastomeric material, single expansionary force with spreading belt can not be followed manhole and be cut the concavo-convex of hole face, therefore has the situation of leaking.
And, with the increase of number of drills, the drill bit abrasion, 2～3mm can be reduced by in the aperture.Cause adopting the spreading belt of appointment not press thus.
Under above rough sledding, must qualitative control completely the manhole manufacturing site location install flexible water-stopping joint.
But, when under the situation of laying pipe with pipe jacking method, using the combined type manhole (at the produce in factory manhole, removing to the scene more in advance) because flexible water-stopping joint need manhole install and with pipe in succession after, could insert manhole and cut between hole and the sewer pipe, so technology in the past is inapplicable.
In the present invention, between the cylindrical body of pipe and rigidity, the manhole structure is housed and uses flexible water-stopping joint,, can not cause problem so cut the concavo-convex of hole face because the manhole structure does not directly contact the hole face of cutting of manhole with the rubber system flexible portion of flexible water-stopping joint.
And, in the present invention, between the cylindrical body of cutting hole face and rigidity of combined type manhole, can attach and above-mentioned people's hole wall bonding bonding material or bonding material of filler, or installing hydroexpansivity macromolecule resin.
In the present invention, a preferred cylindrical body that has to the rigidity of the side-prominent banded protuberance of people's hole wall.This protuberance helps to determine to flow into the position of people's hole wall of cylindrical body periphery with the end of filler.
And this protuberance both can prevent that manhole from overflowing the outside of manhole with filler, also can increase people's hole wall of contacting with cylindrical body thickness with filler, thereby can promote the compactness of cylindrical body and the attaching of people's hole wall.
Described protuberance can adopt different shape, and can be made from a variety of materials.Preferably adopt with the material of cylindrical body homogeneity and make, the people's hole wall that adopts the same ability the to pour into material and the shape of filler with cylindrical body.
Described spreading belt and tight ligament can be made with the macromolecular material with suitable stiff, also can adopt other materials, as long as this material can make the abundant crimping of tubular flexible body be fixed in tubular flexible body and pipe, and abundant sealing are got final product therebetween.
Described each bead, cylindrical body, spreading belt and tight ligament are advisable with steel, especially are advisable with the strong stainless steel material of corrosion resistance.
