Abstract
A caulking material comprises a sheet 10 of a resilient material to be folded, preferably around a neoprene core 21, into a recess between opposed faces 17, 18 of a pair of tunnel lining segments 15, 16. The sheet has a pair of strips 14 of a water-swellable rubber material applied to the sheet at spaced locations on one side thereof to bear against opposed faces 17, 19 of the tunnel lining segments to form a seal therewith which is enhanced by swelling of the rubber when moisture is present. <IMAGE>
Description
IMPROVEMENTS IN OR RELATING TO CAULKING MATERIALS
This invention relate to caulking materials and is particularly concerned with caulking materials for use in joints of tunnel or shaft lining segments.
The invention provides caulking material comprising a sheet of resilient material to be folded into a gap between opposed faces a pair of tunnel or shaft linings, the sheet having a pair of strips of water-swellable material applied to the sheet at spaced locations on one side thereof which, in use, constitutes the outer surface of the sheet to bear against said opposed faces of the tunnel or shaft linings conform a seal therewith.
In one embodiment of the invention the sheet may have a pair of spaced grooves formed in said one side thereof and the water-swellable material may be applied to the grooves.
Further, the water-swellable material may comprise a water swellable rubber.
Preferably the surfaces of the strips of water-swellable rubber material in the respective grooves in the sheet may be substantially flush with the surrounding surface of the sheet.
The caulking material of any of the above arrangements may be combined with a core of resilient material around which the sheet is wrapped to seal between said opposed surfaces.
By way of example the core may be formed from a closed-cell neoprene.
In any of the above arrangements the water-swellable rubber material may be a 1, 3-diene rubber.
The 1, 3-diene rubber may be a rubber containing from 5-50 crystalline regions or glassy regions at room temperature. More specificially the 1, 3-diene rubber may be a chloroprene rubber.
The water-swellable rubber material may be formed as described in European Patent Application
No. 82300783.6.
The following is a description of a specific embodiment of the invention, reference being made to the accompanying drawings in which;
Figure 1 is a sectional view through a strip of material for use in caulking;
Figure 2 is a sectional through a joint between tunnel lining segments embodying a caulking material according to the invention; and
Figure 3 is a similar view to Figure 2 with the segments of the tunnel lining based slightly apart.
Referring firstly to Figure of the drawings, there is shown a material for use in caulking between tunnel/shaft linings comprising an elongate sheet 10 of neoprene rubber having an outer surface 11 and an inner surface 12. The outer surface of the sheet is formed with spaced parallel shallow grooves 13 extending the length of the strip in which strips of a water-swellable rubber sold under the name "Hydrotite" 14 are bonded. The surface of the strips in the grooves is substantially flush with the surface 11 of the sheet.
Referring to Figure 2 of the drawings, there is shown a pair of concrete tunnel lining segments 15, 16. The segments 15, 16 have abutting circumferential edge faces 17, 18. Adjacent the outer periphery of segment 16, edge face 18 is formed with a V section groove and outwardly of the groove the edge face 18 is stepped away from the opposing edge face 17 of the other segment to provide a narrow entry indicated at 20 to the recess between the groove 19 in segment 16 and the edge face 17 of the opposite segment 15. The recess receives the caulking sheet of Figure 1 as can be seen in Figure 2 with the sheet folded about a neoprene core 21 and with one of the water-swellable strips 14 in engagement with the edge face 17 of segment 15 and the other water-swellable strip engaging the sides of the groove 19 to form a seal between the segments.The neoprene core is dimensioned to hold the caulking sheet in sealing engagement with the segments and if any water should reach the water-swellable strips 14 of the sheet material, the sheet material will expand increasing the compressive force between the sheet and faces of the segments. In addition the water-swellable strips will "mould" themselves to the joint surfaces to take up any surface roughness. Thus the caulking provided by the sheet/core will resist penetration of the joint by water and any water reaching the upper side of the joint will tend to run around the outer periphery of the caulking and drain off from the lower part of the joint.
In order to cater for variation in the separation of the segments, cores 21 of different diameters are utilised. Thus if the segments should be separated slightly as illustrated in Figure 3, a larger diameter core is inserted at that location.
In that case the sheet material may be not long enough to extend to both side of the recess 19 in which case it may lie against one side only and the core 21 may projects from between the sheet material -and engage the other side of the recess 19.
The method of application following erection of
the rings of segments is as follows:
1. The sheet material 10 is inserted into the joint with a suitable tool and pushed back into
the recess.
2. Where the gap between segment is zero or small, a small diameter closed-cell neoprene core is
inserted in the sheet material. The the joint gap is large, a larger diameter core is inserted as shown in
Figure 3.
3. Where the joint gap varies between extremes, different core diameters are used to suit.
The caulking material described above can be used on wet surfaces (unlike mastics), does not require any bonding agent or surface priming and can cope with a highly variable joint gap. Furthermore
swell of the water-swellable material helps to compensate for any compression set which may occur in the material.
