Seepage

Water escaping through or emerging from the ground along rather extensive line or surface, as contrasted with a spring, the water of which emerges from a single spot.

Seeper

Applied to infiltration during the first stages to quantify the slow ingress of water into a sewer through a defect or faulty joint.

Segmental Concrete Tunnel Liner

Used the same way as Liner PlateA proprietary product, used to line tunnels instead of casing, and comes in formed steel segments. When these segments are bolted together they form a structural tube to protect the tunnel from collapsing. The segments are made so that they may be bolted together from inside the tunnel. except that they are tunnel liners made of concrete.

Segmental Lining

The use of prefabricated segments in Man-EntryDescribes any trenchless technology process which requires an operative to enter a pipe, duct or bore. OSHA has no minimum size limit for Man-Entry; however, they address a much broader concept of "confined space" in Title 29 Code of Federal Regulations Part 1910.146. The minimum size for which this is permissible in the UK is 900 mm (approximately 36 in.). work to form a new lining within a defective pipe. The segments are usually sealed at the joints and the annulus is grouted. See Lining with Pipe SegmentsMethod of lining with pipe sections made of at least two pieces with both longitudinal and circumferential joints..

Segmental Sliplining

See Sliplining(1) General term used to describe methods of lining with continuous pipes and lining with discrete pipes. (2) Insertion of a new pipe by pulling or pushing it into the existing pipe and grouting the annular space. The pipe used may be continuous or a string of discrete pipes. This latter is also referred to as Segmental Sliplining.. See Lining with Discrete PipesMethod of lining with pipes shorter than the section to be renovated which are not jointed prior to insertion to form a continuous pipe, and which have not been shaped to give them a cross sectional diameter smaller than their final diameter after installation..
