A cable guide includes an upper face and a lower face. The lower face has a generally convex form so as to lie in contact with the flow channel when fitted in the flow channel. The upper face has a generally concave form and is shaped to minimize disturbance of the flow when fitted in the flow channel. A passage is defined between the lower face and the flow channel having an entrance opening at a first end of the cable guide and exit openings on the sides of the cable guide towards a second end. By utilizing a cable guide, disruption to the flow within the channel by the entrance or exit of the cable is minimized.

Laying network cables in sewers

A cable guide includes a substantially cylindrical pipe section with a substantially outwardly projecting flange at one end. A channel is formed in the outside surface of the pipe section and extends from a first point at one end of the cable guide to a second point at the other end of the pipe section and further extends through the flange. The two opposite ends of the channel are located at different positions around the circumference of the pipe section. The channel is sized and configured to provide a passage for accommodating a cable. The channel forms a ridge on the inside surface of the pipe section which is shaped so as to minimize the disturbance to the flow of waste water through the cable guide and, therefore, to decrease the likelihood of blockages occurring.

Cable guide

One form of sewer comprises a pipe having a bottom sectionincorporating a flow channelalong which sewage flows. A cable guidecomprises a body sectionand an arm section. The body comprises a panelcurved so as to be able to lie substantially flush with the walls of the flow channeland the arm comprises a tube with an internal passage. The armprojects from the bodyand the passage within the armextends from an openingprovided in the bodyto an openingprovided at the distal end of the arm. The openingsand the passage within the armare of suitable dimensions to carry a cable. The body is also provided with a cable clip

A network and method of laying network cables in water supply pipes is disclosed. A building is situated near a roadway along which is laid a trunk cable. A water supply pipe branches off the water main to enter the building. A water supply pipe is provided at the time of construction of the building and is an underground pipe. It is conventional to provide a dedicated (and usually underground) conduit for a branch cable, which is expensive and disruptive. In the present invention the branch cable is laid along water supply pipe, enabling the cable to cross between the trunk cable and the building with minimal disturbance of the ground therebetween. This is achieved by introducing cable to pipe by use of a suitable Y-junction at location and removing the cable from the pipe by use of a second such Y-junction at location.
