Description

The manhole retreading construction method

Technical field

The present invention relates to that a kind of enhancing has been corroded even the manhole retreading construction method that renovates manhole interior week of the damaged sidewall of establishing manhole.

Background technology

As the representational job practices in the past of above-mentioned manhole retreading construction method, known have following two kinds of job practicess.

In first job practices, use the barrel-type bag shape corresponding with the shape of manhole inner peripheral surface, have the flexible resin(a) of liquid thermosetting resin to absorb the wadding that material forms by infiltration.Manhole is inserted in the folding back of this wadding, and utilize hydraulic pressure it to be opened, wadding is pressed on the inner peripheral surface of manhole from the inboard of wadding.By the warm water spray wadding is heated then, make the thermosetting resin heat cure of infiltration in wadding, thereby the manhole inner peripheral surface is laid lining (with reference to patent documentation 1).

In second job practices, as existing pipe, assembling external diameter, inner peripheral surface slightly littler than manhole internal diameter is the tubular body of continuous barrel surface in manhole.Therefore, use with existing pipe circumferentially and be divided into a plurality of on the short transverse (pipe range direction) respectively and the corresponding a plurality of fan-shaped parts as formed products (segment member) of parts formation at it.Should insert manhole successively by a plurality of fan-shaped parts, and upwards link in above-mentioned week, and on short transverse, pile up, thereby be assembled into existing pipe.Then, fill filler in the gap in manhole between week and the existing pipe periphery and make its curing, make existing pipe and manhole form one (with reference to patent documentation 2).

Fig. 1～Figure 14 illustrates embodiments of the invention 1.At first, Figure 14 represents the state after the renovation construction of the manhole of present embodiment is finished.As shown in the drawing, in the present embodiment, the manhole 1 of implementing the renovation construction forms the cylindrical shape that has opening 1a in the upper end.The top of the columnar sidewall of manhole 1 forms towards the below diameter and becomes big truncated cone, and the part under it forms certain cylindrical of diameter.Below, the truncated cone on the top of sidewall partly is called the 1b of skew wall portion, the cylindrical part under it is called the straight wall 1c of portion.In addition, the symbol with expression sidewall integral body is made as (1b, 1c).In addition, be formed with the groove 1e of cross section semicircular in shape at the bottom 1d of the circle of manhole 1.This groove 1e is communicated with the Lower Half of the circular open of the pipeline 2 of sewer pipe, and the pipeline 2 of this sewer pipe intersects with manhole 1.

In the renovation construction of present embodiment, form lining (liner) with certain thickness, make it cover the columnar inner peripheral surface integral body of sidewall (1b, 1c).Lining is formed by renovation tablet material 3 and filler 13.Renovation tablet material 3 forms the inner peripheral surface (surface) of lining.Filler 13 is filled in the gap between the inner peripheral surface of sheet material 3 and sidewall (1b, 1c).Filler 13 has flowability, solidifies along with the process of time, for example uses mortar.

Renovation tablet material 3 forms as with the shape of the inner peripheral surface integral body of lining, just the columnar radius of the inner peripheral surface integral body of sidewall (1b, 1c) is reduced the sheet material of the consistent barrel-type bag of columnar shape after the liner thickness.In addition, below the shape of lining inner peripheral surface integral body is called lining face shape.

As the sheet stock of the material of renovation tablet material 3 use soft, have water proofing property and/or anticorrosive property and on the filler (mortar) 13 that solidifies, have the material of stronger adhesive ability.For example, only use the double-deck sheet stock etc. of sheet stock that forms by high density polyethylene (HDPE) or the coat that on the base layer of high density polyethylene (HDPE), is formed with propylene.Such sheet stock is the Preprufe sheet stocks such as (registration marks) that Grace Construction Products company produces.

In the operation of the renovation of present embodiment construction, at first utilize above-mentioned sheet stock, image pattern 1 and form as shown in Figure 2 and renovate tablet material 3.That is, at first will grow and continuous sheet stock cuts into the sheet material 3a shown in the left side among Fig. 1, the shape of 3b.The band shape that is shaped as circular arc of sheet material 3a, form in the figure left border portion and lower lip portion on increased the shape of pasting usefulness portion 31,32.The band shape of above-mentioned circular arc is that the shape with the lining of the 1b of skew wall portion in lining face shape part is that the inner peripheral surface of truncated cone launches and the shape that forms.In addition, the shape of sheet material 3b is that the columniform inner peripheral surface of the lining part of the straight 1c of wall portion in lining face shape launches and increased the shape of pasting usefulness portion 33 in the rectangular left border portion that forms.

Then, paste in the stickup usefulness portion 31 of sheet material 3a after the not shown two-sided tape, 3a rolls with sheet material, and the margo dexter portion among the figure of sheet material 3a is overlapping and stick on the two-sided tape.Then, the splicing tape shown in the right side among the figure 4 is overlapping and stick on the overlapping margo dexter and left border of sheet material 3a.Like this, be to become partly consistent shape with sheet material 3a shape with the 1b of skew wall portion of lining face shape.

In addition, paste in the stickup usefulness portion 33 of sheet material 3b after the not shown two-sided tape, 3b rolls with sheet material, and the margo dexter portion of sheet material 3b is overlapping and stick on the two-sided tape.Then, the splicing tape shown in the right side 5 is overlapping and stick on the overlapping margo dexter and left border of sheet material 3b.Like this, sheet material 3b is formed partly consistent shape with the straight wall 1c of portion of lining face shape.

Then, the stickup of the lower lip of sheet material 3a is overlapped with portion 32 on the last side edge part of sheet material 3b, paste, thereby finish renovation tablet material 3 as the barrel-type bag consistent with lining face shape with the splicing tape shown in the left side among Fig. 26.In addition, the formation operation of top renovation tablet material 3 can be carried out in the renovation job site, but preferably carries out in factory in advance.

Then, at the construction field (site), shown in the central authorities of Fig. 2, renovation tablet material 3 is folded into thinner form, and inserts in the manhole 1 from the opening 1a of the manhole shown in the right side 1.The sectional view of Fig. 8 is represented the form inserted.

But, before this inserts, as shown in Figure 7, a plurality of septs 7 of ring-type are pasted and fixed on a plurality of positions of inner peripheral surface of sidewall (1b, 1c) of manhole 1.After being used to guarantee, this sept 7 between sidewall (1b, 1c) inner peripheral surface and renovation tablet material 3, leaves the gap about the several cm that fill filler 13.In addition, with the rope shape fill out back of the body material 8 with in the inboard, lower end of the straight 1c of wall portion along the periphery of the upper surface of bottom 1d, again along the form at the edge of the first half of the opening of the pipeline 2 that on the straight 1c of wall portion, exposes, fix by bonding grade.It is used to guarantee to fill the gap of filler 13 usefulness, and prevents that filler 13 from flowing out from the lower end.After sept 7 being set like this and filling out back of the body material 8, as shown in Figure 8, will renovate tablet material 3 and insert in the manhole 1.

Then, the people enters in the renovation tablet material 3 that is inserted, and opens sheet material 3 from the inboard.Then, in the bag of sheet material 3, pile up, assemble framed successively from the below, this framed sheet material 3 that makes is stretched on its periphery sheet material 3 is supported to lining face shape.This framed circumferential profile shape and lining face shape corresponding shape that is assembled into integral body.

At first, use the framed block 9 of a plurality of a kind of fan shape shown in Figure 5, to shown in Figure 10, the straight wall 1c of portion of assembling and lining face shape is (cylindrical part) corresponding columniform framed part partly as Fig. 9.Shown in the left side of Fig. 5, framed block 9 be by with plastics with peripheral plate 9a, up and down side plate 9b and the end plate 9c at two ends is integrally formed constitutes.Peripheral plate 9a forms the outer peripheral face of framed block 9, bends to the circular arc of half circumference.The diameter of peripheral plate 9a is than the size of the aggregate value of the thickness of the thickness of the little renovation tablet of the internal diameter material 3 of the straight wall 1c of portion and sept 7 or than its slightly little size.In addition, the height of peripheral plate 9a for example is about tens of cm.Side plate 9b extends along the last lower limb of peripheral plate 9a respectively, stretches out given size towards the inboard of peripheral plate 9a.End plate 9c extends along the edge at the circumferential two ends of peripheral plate 9a, and given size is stretched out in the same inboard towards peripheral plate 9a with side plate 9b., be formed with two hole 9d respectively herein on each end plate 9c, this hole 9d is used for a pair of framed block 9 connected to each other.Though done omission for simplicity of illustration, in fact on the interior week of peripheral plate 9a, extended to form a plurality of ribs that strengthen usefulness along circumferential and above-below direction.

With the renovation tablet material 3 of so framed block 9 in the opening 1a of manhole 1 inserts manhole 1 successively one by one, every with two framed blocks 9 as one group of insertion, the people of the inside just will be somebody's turn to do as such binding the shown in the right side of two framed block 9 image patterns 5 of one group, form the short tube 10 of framed usefulness.At this moment, the end plate 9c at two framed block 9 two ends is separately docked each other.Then, as shown in Figure 6, by the logical bolt 11 of end plate 9c hole 9d interpolation each other after from a side towards butt joint, 11 screw on nut 12 and fastening from opposition side towards bolt, and two framed blocks 9 are connected to each other, can form short tube 10.The outer peripheral face of this short tube 10 is the continuous barrel surface that is formed by peripheral plate 9a.

Like this, the framed block 9 that links two group in the bag of renovation tablet material 3 is successively assembled short tube 10, as Fig. 9～shown in Figure 10, successively piles up on the 1d of the bottom of manhole 1 with level.At this moment, by the outer peripheral face with short tube 10 be pressed on sheet material 3 the bag the inboard, short tube 10 is arranged to level, can make the part tensioning of the sheet material 3 on the outer peripheral face that is pressed on short tube 10, it is supported to the cylindrical shape consistent with the outer peripheral face of short tube 10.

In addition, also can adopt such structure: one in the linking portion at two framed block 9 two ends each other of formation short tube 10 can be adjusted, so that the end plate 9c of butt joint can expand out each other to given size.For this reason, can consider to sandwich sept each other, perhaps adopt the binding structure of screw bolt and nut, adjust size between above-mentioned end plate 9c according to the screw-in amount of nut at above-mentioned end plate 9c.So, just can tackle the straight wall 1b of the portion corresponding big slightly situation of size of diameter partly of renovating in the tablet material 3 with lining face shape.That is, in this case, expand out each other by under the state that sets short tube 10, making above-mentioned end plate 9c, can will be pressed on the part of renovation tablet material 3 on the outer peripheral face of this short tube 10 successfully supported with the state of abundant tensioning.

Like this, assemble identical short tube 10 one by one, as shown in figure 10, pile up multilayer, near the height the upper end of the straight wall 1c of portion of manhole 1.Like this, the assembling columniform framed part partly corresponding with the lining of the straight 1c of wall portion.The corresponding part of renovation tablet material lining part 3 and the straight wall 1c of portion is stretched on the outer peripheral face (outer peripheral face of short tube 10) of this framed part, is supported for the cylindrical shape of above-mentioned outer peripheral face.

Then, carry out the filling of filler 13 as shown in figure 10.That is, fill filler 13 in the gap between the inner peripheral surface of part that is supported by above-mentioned framed part of renovating tablet material 3 and the straight wall 1c of portion.In order to carry out this filling, the container 14 that will be full of filler 13 places near the manhole 1 the ground.Then, by flexible pipe 15, inject filler 13 towards the gap of its below, fill under filler 13 spontaneous currents from the upper end of the straight wall 1c of portion and the position between the renovation tablet material 3 from container 14.

In addition, also can carve at this moment and the moment before, promptly one deck only assembles the bottom of framed integral body to several layers short tube 10 the moment is set at first carries out the filling of filler 13.This is in order to prevent that filler 13 from flowing out from the lower end.In this case, in the filling first of bottom,, preferably fill the filler that solidifies in the short time as filler 13.

Then, use the framed plate 16 of fan shape shown in Figure 3, as Figure 11～shown in Figure 12, the framed part that assembling is partly corresponding with the 1b of skew wall portion of lining face shape.Shown in the left side of Fig. 3, the smooth plate that framed plate 16 forms as circular arc Rack, half circumference.Framed plate 16 for example can be formed by sheet materials such as veneers.Then, with two identical framed plate 16 as one group, shown in the right side of image pattern 3 like that with framed plate 16 each other the two ends butt joint and link with web 18, constitute the circular ring flat-plate 17 of corresponding framed part partly thereby form with the 1b of skew wall portion.

Fig. 4 has represented the binding structure of framed plate 16.That is, form porose 16a in each end of the framed plate 16 that is docked.In addition, on web 18, also be formed with two hole 18a.Each end of framed plate 16 is docked each other overlapping web 18 thereon.Then, distinguish inserting hole 16a and 18a from the below with two bolts 19.Then screw in nuts 21 and fastening across packing ring 20 respectively being projected on the part above the web 18 of bolt 19, thus framed plate 16 is connected to each other, form ring flat-plate 17.

For the framed part of assembling and the 1b of skew wall portion part is corresponding, with two blocks of identical framed plates 16, be two blocks of identical framed plates 16 of diameter as one group, prepare many groups of different framed plates 16 of diameter each other.In the illustrated structure of Figure 12,11 groups have been used.The diameter of the group of the maximum of framed plate 16 is identical with the diameter of the lower end of the 1b of the skew wall portion part of lining face shape, that is to say identical with the straight wall 1c of the portion diameter partly of lining face shape.In addition, the diameter of Zui Xiao group is identical with the diameter of the upper end of the 1b of the skew wall portion part of lining face shape.Differ certain size (for example counting about cm) successively from group to minimum this diameter of a plurality of groups of group of maximum.

With a plurality of groups of groups from the diameter maximum of so framed plate 16, the size order of pressing diameter inserts under the state that does not link in the bag of renovation tablet material 3 successively by group, links to form ring flat-plate 17.Then,, will be arranged to level by sept 22 by the ring flat-plate 17 of the size order assembling of diameter successively, and keep up and down being deposited in step by step under the state of roughly certain appropriate intervals (for example about 5cm) on short tube 10 framed as Figure 11～shown in Figure 12.As stereogram, Figure 13 also shows its form.Like this, assembling and the corresponding framed part of the 1b of skew wall portion part step by step.

In addition, for suitably adjust ring flat-plate 17 each other between the upper and lower every with the levelness of ring flat-plate 17 etc., sept 22 preferably can be adjusted height changeably.But, also can with the sept of the certain altitude corresponding with above-mentioned interval and can overlapping side disposed thereon or the thin sept used of the Height Adjustment of below be used in combination.

As mentioned above, assembling like that shown in the framed part energy image pattern 12 corresponding with the 1b of skew wall portion part.This framed part that assembles becomes the corresponding truncated cone shape of shape of the 1b of skew wall portion part of circumferential profile and lining face shape that a plurality of ring flat-plates 17 pile up the integral body of formation.In addition, the periphery of each ring flat-plate 17 of this framed part is pressed in the inboard of the bag of renovation tablet material 3, thereby as hand lamp, tensioning renovation tablet material 3 supports to above-mentioned truncated cone shape with it on the periphery of this framed part integral body.

Then, once more as the filling of carrying out filler 13 as shown in Figure 12.Promptly, pass through flexible pipe 15 from the container 14 that places ground filler, gap injection filler 13 between inner peripheral surface from the position between the upper end of the upper end of the 1b of skew wall portion and renovation tablet material 3 towards the 1b of skew wall portion of its below and the renovation tablet material 3 is filled under filler 13 spontaneous currents.Then use the not shown portable filling container that has inlet, fill filler 13 towards the gap between the upper end of the upper end of the 1b of skew wall portion and renovation tablet material 3.

After the filling of filler 13 is finished, wait for that the filler 13 of being filled all solidifies.Solidify by filler 13, renovation tablet material 3, filler 13 and sidewall (1b, 1c) form one.The certain thickness firm lining that is formed by renovation tablet material 3 and filler 13 can form with the form of the inner peripheral surface of covering sidewall (1b, 1c).

After filler 13 solidifies, with the framed decomposition in the manhole 1 and remove.Afterwards, as shown in figure 14, utilize encapsulants 24 such as epoxy resin, seal between the periphery with the first half of the opening of the periphery of the lower lip of renovation tablet material 3 and bottom 1d and pipeline 2.The moment before this will be sealed the part excision of renovation tablet material 3 of the first half of the opening of pipeline 2 in advance.In addition, utilizing encapsulant 23 will renovate between the periphery of the periphery of upper end of tablet material 3 and opening 1a seals.Like this, the renovation construction is finished.

The lining that utilizes above-mentioned construction to form, the interior week that can strengthen sidewall (1b, 1c).In addition, utilize, can prevent that sealing and moisture enter sidewall (1b, 1c) the renovation tablet material 3 of water proofing property lining as surperficial (inner peripheral surface).
