Abstract
In order to seal a crack or joint gap 1 in a tunnel wall, a groove or channel 2 is cut along the crack or gap and a waterproof strip, which may be in sections 3 sealingly bonded together, is attached in a watertight manner by its edge portions to the tunnel wall at opposite sides of the groove or channel. The strip is provided with waterproof fasteners F. Water seeping through a crack or gap 1 either flows along the groove or channel or falls on to the strip and flows along the strip to a drainage gully whence it can be discharged from the tunnel. The fasteners can be opened to enable the groove or channel 2 and the adjoining face of the strip to be cleaned, and can then be closed again to re-make the seal. <IMAGE>
Description
SPECIFICATION
Improvements relating to the watertight sealing of cracks and joints in tunnels
This invention relates to tunnels and is concerned with the sealing of water leaks through cracks or joints in the tunnel wall.
The tunnel must not only be strong and robust but must also have proper arrangements for dealing with water leaking through the tunnel wall, whether underground or undersea, because otherwise the water leakage may be dangerous especially if the tunnel has electric wiring, as in an electric railroad tunnel.
Water may leak in through a joint in a concrete wall of the tunnel or through a crack in the tunnel wall.
One conventional practice when there is a water leak through a crack or joint in a concrete tunnel wall is to cut a groove wider than the gap or crack in the concrete so that the gap or crack comes within the groove, and to secure a waterproof plate to the tunnel to seai the groove watertight so that the leak water may flow down the groove and then be discharged. Though this method works in preventing the leakage water from dripping into the tunnel, it has the disadvantage that over a long period dirt will accumulate in and may even clog the groove, emitting an unpleasant smell. This phenomenon is especially noticeable in undersea tunnels.
This invention is concerned with enabling dirt and other substances adhering to the groove to be easily removed when necessary.
According to the present invention there is provided a sealing device for a tunnel comprising a waterproof strip extending along a crack or joint in the inner surface of the tunnel wall, said strip having its lengthwise-extending edge portions respectively sealingly secured to the said surface at opposite sides of the crack or joint said waterproof strip having one or more waterproof fasteners which can be opened to provide access to the surface of the strip facing the crack or joint and which can be re-closed.
The invention also provides a tunnel having a crack or joint in the wall thereof covered by a sealing device on the inner surface of the tunnel wall, the sealing device comprising a waterproof strip having its lengthwise-extending edge portions respectively sealingly secured to the said surface at opposite sides of the crack or joint said waterproof strip having one or more waterproof fasteners which can be opened to provide access to the surface of the strip facing the crack or joint and which can be re-closed.
The invention further provides a method of sealing a crack or joint in a tunnel comprising the steps of forming a groove or channel in the inner surface of the tunnel wall to the base of which groove or channel the crack or joint opens, and sealingly securing to the said surface at opposite sides of the groove or channel the lengthwiseextending edge portions of a waterproof strip having therein one or more waterproof fasteners which can be opened to provide access to the surface of the strip facing the crack or joint and which can be re-closed.
One embodiment of this invention will now be described with reference to the accompanying drawings in which:
Figure 1 is a view of the inside face of a tunnel according to the invention,
Figure 2 is a sectional view of the tunnel joint in
Figure 1, and
Figures 3 and 4 respectively show sectional views corresponding to Figure 2 but showing modified arrangements for securing the waterproof strip in place.
Reference numeral 1 indicates a gap at a joint in the concrete wall of a tunnel t. Reference numeral 2 represents a recess or groove which is formed in the concrete along the gap 1 and which is wider than the gap 1. A waterproof strip made of neoprene rubber and having watertight fasteners F at appropriate locations is secured in a watertight manner to the tunnel t to seal the recess 2, which can communicate with the open air in the tunnel when the fastener F is opened.
The strip 3 may be continuous or, as shown, may be in lengths which are welded or otherwise bonded together end to end in a watertight manner, and the fastener F in each length may extend over only part of the length. For purposes of securing the strip to the tunnel wall two rows of watertight cushion members 4 are bonded by a bonding agent 5 to the surface of tunnel t on each side of the recess 2. A caulking compound is charged between the cushion members 4, and the waterproof strip 3 is placed on them and secured to the tunnel 5 by anchor bolts 7.
In this way the gap in the tunnel is sealed and the recess 4 is made to communicate with a drain (not shown). In the tunnel thus constructed, if water leaks in through the gap 1 from the ground above the tunnel, the water will flow down the recess 2 or fall onto the waterproof strip 3 and then flow down the strip 3 to the drain, to be pumped or otherwise discharged from the tunnel.
Over a long period, dirt and other substances may accumulate and adhere to the surface of the recess 2 and the waterproof strip 3, blocking the passage of water through the recess and emitting an unpleasant smell. These latter effects can be avoided by opening the watertight fastener F periodically and cleaning the recess 2 and waterproof strip 3.
Though in this embodiment the watertight fasteners F are arranged lengthwise with respect to the waterproof strip 3, i.e. along the circumference of the tunnel t, this invention is not limited to this arrangement. The fasteners may be arranged transversely or stepwise.
The waterproof strip 3 with the watertight fastener F may alternatively be bonded in a watertight manner to the tunnel t as shown in
Figure 3 or Figure 4.
Referring to Figure 3, a block 8 made of rubber or synthetic resin which is U-shaped in cross section is bonded in a watertight manner to the tunnel t on each side of the recess 2, and the waterproof strip 3 is placed on them and firmly secured to the tunnel t by anchor bolts 7.
In the arrangement of Figure 4, a groove 9 is formed in the tunnel ton each side of the recess 2 and a block 10 of rubber or synthetic resin is fitted into the groove 9 with caulking compound 11 charged between them. Placed on these blocks 10 is the waterproof strip 3 which is secured to the tunnel t with the anchor bolts 7 penetrating the strip and blocks.
The methods described above can thus be applied in preventing water from dripping into the tunnel when the water leaks through a gap at a concrete joint or through cracks formed in the tunnel concrete, and can be applied either during or subsequently to construction of the tunnel.
Claims (7)
