Definitions
- ABSTRACT A method of laying generally horizontal wellpoint/- drainage tubing, comprising excavating a trench by mechanically digging out spoil which is then directed away from said trench, laying wellpoint/drainage tubing at the bottom of said trench, and backfilling the trench wholly or partially with water-pervious material other than said spoil, so as to promote a flow of ground water to the tubing.
- a mobile machine for digging and backfilling trenches comprises digging means for excavating spoil to form a trench along a predetermined route at a predetermined depth, directing means arranged to direct the spoil excavated by said digging means away from the trench, and backfilling means associated with the digging means for backfilling the trench with material different from the spoil.
- SUMMARY OF THE INVENTION point/drainage tubing comprising excavating a more or less continuous trench by mechanically digging out soil or the like which is then directed away from said trench, laying a length of flexible or semi-rigid wellpoint/drainage tubing at the bottom of said trench, and back-filling the trench either wholly or partially with suitably pervious material which promotes flow of water to the tubing.
- An open end of the length of wellpoint/drainage tubing may then be connected to a suction pump to draw water from the ground.
- gravity drainage may be achievable.
- Said suitably pervious material may be gravel, aggregate, or other material with similar properties.
- a mobile machine for forming trenches comprising a cutter or digger arm arranged to excavate a relatively narrow trench along a predetermined route at a predetermined depth, means to direct the excavated soil or the like away from the trench, and means for back-filling the trench with material other than said excavated soil or the like or a minor proportion thereof.
- the machine may also be provided with means for laying a length of wellpoint/drainage tubing in the trench as the machine excavates and back-fills.
- FIG. 2 is a perspective view of the machine of FIG. 1, with some modifications, in operation.
- the machine comprises a digger arm which is formed with a series of selfcleaning cutters 11 mounted on an endless chain.
- the machine may be mounted on self-laying tracks 12 of well-known form so that, when advancing along the line ofthe trench to be dug, the cutter arm 10 operates as a chain saw to excavate a. slot-like trench of the order of one foot wide and up to I5 or possibly 20 feet deep.
- a deflector plate 13 or similar device may be provided to direct the flying spoil to one side of the trench being dug.
- a conveyor (20 FIG.2) may be provided to carry the spoil to other means of disposal.
- the machine may also carry a coil of flexible or semirigid plastics tubing 14 which is preferably corrugated and is formed with suction openings along its length.
- the suction openings may be formed as a series of axial slits which also operate as filter openings, but an additional filter, for example in the form of a woven nylon sleeve, may also be provided around the tubing.
- the tubing is fed through a guide 23 into the newly excavated trench to lie along the bottom of the trench.
- the machine is also provided with a hopper 15 containing suitably pervious material such as gravel or aggregate 22, and a chute 16 extends into the trench so that, as the tubing is being laid at the bottom of the trench, the trench is back-filled over the tubing with the gravel, aggregate or the like, which is pervious to water.
- the chute 16 is provided with removable plates at the rear so that the level to which back-filling is effec'ted can be varied.
- a pair of metal tongues 17 may be provided along the working length of the digger arm 10 to hold the possibly unstable trench walls apart during laying of the tubing and also during the subsequent back-filling.
- the machine described above can be employed to lay horizontal tubing at relatively high speeds, and the back-fill of gravel or aggregate accelerates draining of ground water towards the tubing and may also act as a wick to carry water past any lenses of lower permeability (e.g. of clay) which might be present in the area in question.
- the tubing may be connected to a pump to act as horizontal wellpoint tubing or may feed to a suitable lower-level outlet to act as drainage tubing.
- the trench is back-filled as described above but the wellpoint/- drainage tubing 14 will not be laid.
- a method of laying generally horizontal wellpoint/drainage tubing for use in the dewatering of ground comprising progressively excavating a slot-like trench having a width which is small in comparison with the depth of said trench by advancing a digging mechanism along a predetermined route to mechanically dig out spoil, said digging mechanism including a substantially vertically oriented endless chain having a series of cutters thereon, said endless chain and its cutters being driven along a closed.
- said closed path having a length along said trench which is substantially smaller than the depth of said trench, supporting the sides of said trench as said excavating step proceeds by positioning a pair of vertically oriented horizontally spaced plates adjacent the sides of said trench and by advancing said plates along said trench together with said digging mechanism, directing the spoil brought to the top of said trench in a lateral direction away from and to one side of the trench being dug to prevent at least the majority of the spoil removed from the trench from being returned to the trench, laysaid tubing along said predetermined route together with said digging mechanism and supporting plates and by progressively feeding said continuous length off said coil and through a substantially vertically oriented guide structure which is located between said supporting plates at a position rearward of said digging mechanism, said guide structure extending into said trench to a position adjacent to but spaced from the bottom of said trench and said guide structure being advanced along said trench together with said supporting plates to direct said tubing in a substantially vertical direction toward the bottom of said
