Abstract
This invention relates to a lining segment for tunnels e.g. sewer tunnels, comprising an arcuate member of synthetic plastics material, a plurality of which will form a circular lining, each segment having ribs 25 formed on its outer surface and extending around the edges of the segment. The side edges 10, 11 of each segment may be formed with grooves 12 and tongues (not shown) to interconnect adjacent segments. Alternatively the segments may be provided with rebates along their inner edges, the rebates being filled with mastic after assembly of the lining. <IMAGE>
Description
SPECIFICATION
Improvements In or Relating to Tunnels
This invention relates to tunnels e.g. sewer tunnels. Such tunnels are generally made of brickwork subject to deterioration and it is the object of the present invention to provide means for, and a method of, reconditioning tunnels.
According to the present invention I provide an article suitable for lining a tunnel comprising an arcuate member of synthetic plastics material suited to the shape of a tunnel and having end transverse surfaces of adequate radial depth to abut against the corresponding surfaces of a similar articles 7nd to be veined theretc, and provided with ribs of similar depth at its edges and on its outer side.
The invention further includes a method of improving a tunnel which consists in lining the tunnel with a plurality of the aforesaid articles joined together.
The invention will be further described by way of example with reference to the accompanying diagrammatic drawings wherein: Figure 1 is a perspective view of an article made in accordance with the invention;
Figure 2 is an end view of a tunnel lining made with such articles;
Figures 3 to 6 are views showing means and methods of joining two articles together;
Figure 7 is a perspective view of the assembled articles; and
Figure 8 shows the application of the tunnel at a manhole.
The article shown in Figure 1 may be a single integral homogeneous article moulded to arcuate form or made flat and then bent. It is made of synthetic plastics material such as polypropylene and may contain fillers such as glass fibres, stainless steel, iron, wood, titanium, aluminium, tin brass, copper and/or other materials for stabilizing or strengthening the article. It is of arcuate form of a shape which will fit against the wall of a tunnel and as shown fits around 90 degrees so that four of them formed together as shown in Figure 2 will extend completely around a circular tunnel wall. The articles will be also secured together lengthwise along the tunnel.
The article has a sufficient radial thickness to provide end walls 10 and side walls 11 which can be fixed to adjacent similar articles. Thus the walls 10 may be grooved as at 12 and adjacent articles may be provided with ribs 13 to engage in the grooves as shown in Figure 4. Alternatively adjacent articles may have grooves as shown at 1 5, 1 6 (Figure 3) at their inner arcuate corners which can be filled with a mastic 17. The joints may be heat welded e.g. at 18, Figure 3, or may be stuck with adhesive as at 20, 21 Figure 4.
Figure 2 shows four joints at 22 at the sides of the tunnel i.e. offset from the top and bottom and which might be weaker under load. The side articles in this example are shorter than the top and bottom articles in end view.
The articles are assembled into rings which may be assembled from quarter sections 500 mm wide by 1-50 m long. These sections may be joined together by joints, welding and/or solvent or adhesive.
The sewer lining may be constructed out of 25 mm thick polypropylene sheeting and each section, or article, will be provided with ribs 25 on its outer side and at its end and side edges. The articles and the joints will be watertight and acid and alkaline resistant.
In the example shown in Figure 5 a mastic, rubber or other sealant is provided at 26 across the adjacent faces of two articles. In the example shown in Figure 6 the sealant is provided at 29, 30 between the rib 13 and adjacent surfaces 20, 21 of the groove 12.
In order to allow for any irregularities in the walls of existing sewers there will have to be a proper survey before installation as it is possible to extend the strengthening ribs to allow to take up the irregularities.
The articles enabie a lining to be installed by one person.
The internal surface of the joined up articles will provide a smooth surface devoid of any undulations.
Where the lining pipe abuts a manhole as shown in Figure 8 the sections can be arranged using a purpose made article to form an access chamber 31. The article may be fabricated on site using glass reinforced plastics, steel or fibre glass or because of easy access the completed pipe can be incorporated and sealed flush with the face of the new brickwork in the access chamber. The floor and the sides of the access chamber, if constructed in brickwork, will have a smooth trowelled finish to the same contour of the pipe to facilitate the smooth flow which will have developed in the pipe. Where there are voids behind existing sewer wall over a critical dimension the size of which will be determined by the engineer grout or any other suitable substance will have to be injected. An access ladder is shown at 32. The street level is indicated at 33 and the manhole cover is not shown.
