Abstract
The lining of a sewer is effected by means of sheets 18, 19 of plastics material so formed and shaped that, when assembled, they conform to the cross-section of the sewer, the longitudinal edges of the sheets being formed with interlocking tongues 20 and grooves 21 whereby the sheets may be connected together to form a lining. The abutting ends of adjacent lining sections may be connected by means of locking rings or by means 22, 23 formed integrally with the lining sheets. <IMAGE>
Description
SPECIFICATION
Improvements in or Relating to Sewers,
Tunnels and the Like
This invention relates to the lining of sewers, tunnels and the like.
Various methods have been proposed for the lining of sewers, tunnels or the like (hereinafter referred to as sewers) such as the use of glassreinforced concrete and glass-reinforced plastic materials.
The invention has among its objects to provide simple and effective means for lining a sewer that are easy to manufacture and install within the sewer.
According to the invention in its broadest aspects, means for lining a sewer comprise two or more sheets of plastics material so formed and shaped that, when assembled, they conform to the cross-section of the sewer, the longitudinal edges of the sheets being formed with interlocking tongues and grooves whereby the sheets may be connected together to form the lining.
The invention also provides means for connecting sections of lining constructed as described in the preceding paragraph. According to one embodiment, said connecting means comprises a locking ring which is adapted to engage the abutting ends of adjacent lining sections, the locking ring being provided with an internal flange to engage the end of a lining section to hold the ring in position on the lining.
According to another embodiment, the adjacent end faces of the lining sections are formed with interlocking tongues and grooves, the tongues being secured in the grooves by means of pins. This method of connecting the lining sections is particularly applicable in the case of sewers of large bore.
According to yet another embodiment that enables sections of !ining to be inserted and positioned within the sewer without it being necessary for workmen to enter the sewer, each lining sheet is formed integrally at one end thereof with a peripheral flange that projects beyond the end of the sheet, the flange on a sheet that is to form part of the upper portion of the sewer having its end portions of greater diameter than the flange on the sheet that is to form part of the lower portion of the sewer, whereby said upper sheets may be slid into position over the lower sheets previously slid into position.
According to another feature of the invention, the tongues and grooves on the longitudinal edges of the lining sheets are so formed that the assembled lining has a smooth and unobstructed inner surface.
The lining sheets may advantageously be formed by moulding a thermosetting polyester resin of the isophthalic type reinforced with glass fibres. Alternatively, the lining sheets may be made by extruding or injection moulding a thermoplastic resin such as polyvinyl chloride.
It is particularly advantageous to use a transparent or translucent material for the production of the lining since it is then possible to check visually that the space between the lining and the wall of the sewer has been satisfactorily grouted.
The invention will now be described by way of example with reference to the accompanying drawings, in which:
Figure 1 is an exploded sectional view of one embodiment showing two lining sheets about to be assembled,
Figure 2 is a perspective view of the assembled lining,
Figure 3 is an exploded perspective view of another embodiment,
Figures 4 and 5 are end views and longitudinal sections respectively of the assembled sections, and
Figure 6 illustrates the method of installation.
In the embodiment illustrates in Figures 1 and 2, each section of the lining is formed from two sheets 10 and 11 of translucent glass-reinforced polyester resin which are so formed and shaped that when assembled they form a lining conforming to the cross-section of the sewer. The longitudinal edges of the sheet 10 are formed with offset tongues 1 2 which are adapted to engage grooves formed by channels 13 on the longitudinal edges of the sheet 11 such that the inner surfaces of the lining are smooth and presents no obstruction in the bore of the sewer, since the longitudinal edge of the inner arm of the channel 13 coincides with the edge of the sheet 10 from which the tongue 12 is off-set, as indicated at 14 in Figure 2.
Adjacent sections of the lining are connected by means of a locking ring 1 5 which is formed on one rim with an outwardly flared lip 16 to facilitate its positioning on the lining section and internally with a flange 1 7 to engage the end of said section.
The operation of lining the sewer is carried out as follows.
The sheets are loaded as required into the sewer without the necessity of removing the main manhole cover. The sheets are then assembled to form the lining by the engagement of said longitudinal tongues and grooves. A flexible adhesive sealant may be inserted in the groove and the tongue is pressed into the packed groove to form a watertight joint that allows for expansion and contraction. Unless other steps are taken, it would be necessary to leave the joint for several hours before it can be disturbed but this delay is avoided by applying and, if necessary, bonding the locking ring to an end of the lining section. The space between the lining and the wall of the sewer is then filled by conventional grouting and the fact that the lining is translucent enables the grouting operation to be checked visually.
Referring now to Figures 3 to 6, each section of the lining is formed from two sheets 18 and 19 of translucent glass-reinforced polyester resin which are so formed and shaped that when assembled they form a lining conforming to the cross-section of the sewer. The longitudinal edges of the sheet 1 8 are formed with off-set tongues 20 which are adapted to engage grooves formed by channels 21 on the longitudinal edges of the sheet 1 9 such that the inner surface of the lining is smooth and presents no obstruction in the bore of the sewer, since the longitudinal edge of the inner arm of the channel 21 coincides with the edge of the sheet 18 from which the tongue 20 is off-set.
The sheet 1 8 is formed integrally at one end, which may be termed a socket end, with a peripheral flange 22 which projects beyond the end of the sheet, while the sheet 1 9 is formed with a similar flange 23. The edge portions of the flange 23 are of greater diameter than the flange 22 so that the sheet 19 may be slid over the sheet 18.
This construction enables the lining sections to be inserted and positioned within the sewer without it being necessary for workmen to enter the sewer. Thus, as shown in Figure 6, the lower sheets 1 8 are first slid into the sewer with the spigot ends engaging the socket ends. The upper sheets 1 9 are then slid into position over the lower sheets with the tongues 20 engaging the channels 21 and the flange 23 overlapping the flange 22. The space between the lining and the wall of the sewer is then filled by conventional grouting. The engagement of the flanges 22 and 23 locks the sections together and prevents distortion during grouting operation.
The formation of the lining from sheets of lightweight plastics material of adequate strength has the advantage that the sheets can easily be handled, transported, inserted into the sewer and assembled, without the use of cranes. The sheets can be made of any desired curvature to suit the cross-section of the sewer and of various lengths for ease of working.
The invention also comprises a sewer system, wherein the sewer has a lining comprising a plurality of sections according to the invention, said sections being connected together by means of locking rings applied to the abutting ends of the sections or by means of interlocking means formed integrally on the ends of the sections.
