摘要： A process is disclosed for sinking and sealing a blast hole for the seismic reconnaissance of geologic formations. The blast hole is sunk by a direct flush drilling process and is filled with a sealing material. As drilling fluid a slowly hardening hydraulic suspension made of water and a finely granulated mixture of clay minerals and hydraulic binder is used. After the blast hole is finished and the charge of explosives is introduced therein, the blast hole is filled with the suspension set so that it cures within 48 hours within the blast hole into a tight and solid stopper.

摘要： The invention concerns a method of replacing a plastic pipe line (15) by a new pipe line (30), the existing pipe line being ripped open and its bore increased by means of ram-driven drilling device (5) to produce a passage whose diameter is greater than the external diameter of the new pipe line, the new pipe line being drawn into the passage thus formed at the same time as the existing pipe line (15) is widened. The invention calls for the existing pipe line (15) to be cut into several strips along the longitudinal axis of the pipe line, these strips being forced radially outwards without being separated from the pipe line and the drilling device being supported by the strips of pipe line in the direction opposite to the direction of advance of the drilling device.

摘要： In a process for removing the earth core (7) from a pipe (5) laid without excavation by ramming or pressing, both ends of which are free, a scraper (1) is inserted into one end of the pipe and moved longitudinally through the pipe (5) so that the earth core (7) is pushed out of the other end of the pipe by the scraper (1). The scraper (1) is advanced in stages by means of a variable-length thrusting device (10) supported on the inner wall (4) of the pipe (5). The thrusting device (10) is returned to its initial position after each thrusting stroke and its support in the drive device is adjusted by the length of the stroke made. The scraper (1) consists of a header plate (2), a variable-length thrusting device (10) and clamping devices (11, 22); the header plate (2) is secured to one end of the thrusting device (10) and a first clamping device (11) and the other end of the thrusting device (10) is secured to a second clamping device (22). The clamping devices (11, 22) can be moved alternately into a clamping position in which they can be pressed against the inner wall (4) of a pipe and into a released position in which they are released from the inner wall (4) of the pipe (5).

摘要： Pipework for constructing a ground water measuring point with several measuring places arranged at different depths comprises a single multichannel pipe composed of individual, tightly connected lengths of pipe (4). The multichannel pipe has a smooth outer wall which can be filled and packed. The lengths of pipe (4) are divided by longitudinal dividing walls (5) into several channels (6a-6d) and are joined to each other in such a manner that their channels (6a-6d) are aligned with each other and not constricted at the junctions. Filter sections for admission of water are formed by individual lengths of pipe which have filter slits (9) in their outer wall in the region of one or more channels.

摘要： According to a process for carrying out civil engineering works in the area of the sole (4) of an existing waste dump, passable shafts (1, 2) designed as mutually spaced, cased large hole borings are sunk down to the waste dump sole (4). At the level of the waste dump sole (4) the shafts (1, 2) are interconnected by a passable tunnel (5), forming a continuous working room. A sufficiently large working room is thus simply created above the waste dump sole (4) for carrying out sanitation works.

摘要： The pipeline described comprises an outer pipe (2) with a medium-conveying pipe (1) disposed a certain radial distance inside it, the medium-conveying pipe (1) being surrounded by thermal insulation (3). The medium-conveying pipe (1) rests on spaced anchor points (6) which press axially against the outer pipe (2). The thermal insulation (3) consists of compression-resistant shaped elements, which are made in particular from glass or mineral micro-fibres and which are sufficiently resistant to compression that the medium-conveying pipe (1) is held by the insulation at a suitable insulating distance from the inside wall of the outer pipe (2).

摘要： In a releasable union for large pipes with a pipe sleeve (3) and a pipe spigot (4) insertable into said sleeve (3), the sleeve (3) and the spigot (4) have a plurality of evenly spaced supporting components (6, 13) on their inner and outer sides respectively with bearing surfaces (7, 14) which lie in the same plane perpendicular to the pipe axis. Between the supporting components (6, 13) there are recesses (15), where the peripheral length of the recesses (8, 15) on the spigot (4) exceed that of the supporting components (6) of the sleeve (3). After assembly, the spigot (4) is rotated in relation to the sleeve (3) through half the distance between the supporting components (6, 13) whereby the supporting components (6, 13) cover one another axially so that their bearing surfaces (7, 14) support one another and provide a positive union between the sleeve (3) and the spigot (4) in the tensile direction.

摘要： In the installation proposed, a retentate chamber through which the liquid or gas mixture flows is partitioned off from a permeate chamber by a semipermeable membrane composed of a number of separate hollow-fibre modules. In order to be able to accommodate a large-surface-area membrane in a small space and to keep flow losses small, the permeate chamber is formed by a long-sided tubular container (1) through which cylindrical sleeves (9) pass at right angles to the container axis, the sleeves making a pressure-tight seal with the container wall. The sleeves (9) have openings inside the container (1), and the two ends of each sleeve, which are closed by caps (4), are connected up to a feed line (6) and a retentate line (7) respectively. Fitted inside each sleeve (9) is a membrane cartridge (13) containing a bundle of hollow fibres, the open ends of each fibre connecting with the feed line and retentate line.
