The invention relates to machines for filling and compaction of soil.A device for filling and compacting soil in trenches, which includes the basic machine with built in her sleepy auger and vibroplates mechanism.A disadvantage of this device is the fragility of the working body and the high energy intensity of the process.The closest technical solution is a device for backfilling and compacting soil in trenches, which includes base machine, a frame, a working body containing thrower soil .The disadvantage of this device is the low quality backfill and compaction. The aim of the present invention is polisen basic machine where the bunker, to the lower part of which is attached a guide surface casing, and mechanism of force feeding ground, equipped with a dosimeter, a check valve and an elastic shutter with adjustable stiffness, which divides the guide casing on the upper and lower chambers, the upper chamber with an additional hole is connected to the mechanism of force feeding ground in the form of an air pump, a check valve is installed between the last and the additional hole, and the dosimeter between the hopper and the top of the camera casing, and an elastic shutter is equipped with a spring-controlled fluid.In Fig. 1 shows the device, General view; Fig. 2 - elastic shutter; Fig. 3 - section a-a in Fig. 2.The device consists of a frame 1, which is fixed to the base machine 2 through a hinge 3 to the frame 1 attached to the guide casing 4, which is divided elastic stopper 5 on the top 6 and the bottom of the camera. The upper chamber 6 has two holes, one of which is intended for submission to it of the ground 7 of the hopper by means of the instrument 9, and the other through the check valve 10 is connected to the mechanism of force feeding ground in the form of an air pump 11, and the air pump 11 has a rigid kinetic the element 12, made of elastic material, a spring 13 and the adjusting screw 14.The device operates as follows. When moving the machine base 2 along the trench the guide casing 4 through a hinge 3, associated with the frame 1, is lowered to the operating position. Portions of the ground 7 by a dosimeter 9 fall from the hopper 8 into the upper chamber 6 of the guide casing 4. Compressed air from the air pump 11 through the check valve 10 is supplied to the upper chamber 6. The elastic element 12 of the elastic stopper 5 is adjusted to a predetermined hardness by means of a spring 13 and an adjusting screw 14, prevents the promotion of a portion of the soil 7 for guiding the casing 4 and creates in the upper chamber 6 high pressure. When the pressure of air in excess of the elastic properties of the shutter 5, the portion of the soil 7 sweep through the elastic stopper 5 on the guide casing 4 in a trench having a large kinetic energy, which in the fall is soil compaction.In connection with the use of an air pump that creates a high pressure, increases the efficiency of the process of laying the soil in the trench. The reliability and simplicity of design gives the advantage of this device over the prototype.So obratnykh technical solutions (analogues) in the study area leads to the conclusion about the absence of these signs, similar to the significant distinguishing features of the claimed device tab of the soil in the drainage trench, and to recognize the claimed technical solution meets the criterion of "significant differences".1. The DEVICE TAB of the SOIL IN the DRAINAGE TRENCH that includes the basic machine with installed on the hopper to the bottom of which is attached a guide surface casing, and mechanism of force feeding ground, characterized in that, to improve the quality of the backfill, it is equipped with a dosimeter, a check valve and an elastic shutter with adjustable stiffness, which divides the guide casing on the upper and lower chambers, the upper chamber with an extra hole, is attached to the mechanism of force feeding ground in the form of an air pump, a check valve is installed between the last and the additional hole, and dosimeter between the hopper and the top of the camera casing.2. The device under item 1, characterized in that the elastic stopper is equipped with a spring with variable stiffness.
SUBSTANCE: trench-burying device comprises a frame, a displacement mechanism, two dump scrapers and an accessory for displacement of dump scrapers. Dump scrapers are arranged symmetrically to the longitudinal axis of the frame symmetry, are hingedly connected to the frame and are installed as capable of rotation in the horizontal plane. The trench-burying device comprises an accessory for monitoring a displacement course and a guide block. The guide block is arranged with a connection element and with a working surface for interaction with the external surface of the installed pipeline. One end of the connection element is kinematically connected with the guide block. The connection element with the other end is connected to the frame by means of the hinged joint, which is arranged on the longitudinal axis of the frame symmetry. The accessory to monitor the displacement course is kinematically connected with the guide block.

SUBSTANCE: pipeline is mounted on a deck of a pipe laying ship and laid at the water reservoir bottom. A column of two machines moves along the pipeline: a pipe burying barge and a trench burying machine at some distance from each other, which is technologically substantiated, but not more than 100 metres. The pipe burying barge excavates a trench immediately under the pipeline and lays the developed ground into accurately shaped dumps on both sides; the pipeline is lowered into the trench under action of dead weight. The trench burying machine displaces the formed dumps into the trench and covers the laid pipeline with the ground earlier extracted from under it. Machines operate in an automatic mode, remotely controlled and provided with energy along cables hung on floats from an underwater or surface basic ship. The pipe burying barge is made in the form of two working elements of a back-acting shovel, which are mirror-like located relative to each other and each of which has the possibility of being turned in a horizontal plane and laterally inclined by means of horizontal and inclined hinges. Reactive forces of the working elements are closed on a common frame and not transmitted to a travelling gear.
EFFECT: improving efficiency and reducing costs at performance of works.

SUBSTANCE: construction method of adits containing a water-receiving element in the form of a solid unit of n number (n>2) of vertical longitudinal toe filters involves trench excavation by means of an excavating and drainage machine, laying into it of a drain pipe covered with protective filter material, and refilling of the trench by means of a padding device moving synchronously with the drainage machine and provided with a bunker for filter material with a drain chute. Laying of the drain pipe covered with protective filter material and refilling of the trench is performed simultaneously. The drain pipe covered with protective filter material is padded throughout the trench width to the depth of 15 cm above its crown from a duct to which filter material is supplied from the bunker via the drain chute. The duct represents a rectangular parallelepiped having width equal to trench width, and height that is somewhat bigger than trench depth. Duct bottom is located near the trench bottom at the distance of padding layer thickness of the drain pipe relative to the trench bottom. The duct is rigidly attached with front wall 7 to housing 8 of the excavating and drainage machine. On rear 9 wall of the duct there installed on the outer side are (n-1) vertical partition walls 10 parallel to each other and to walls 1 of the trench with a possibility of changing the distance between them according to thickness of the filters. Height of each of partition walls 10 is equal to the duct height. The filter material bunker is divided into sections by means of partition walls with a possibility of changing the distance between them and their number so that the number of bunker sections is more by one than the number of vertical longitudinal toe filters of the adit. Each bunker section is provided with its own drain chute, from which each adjacent vertical longitudinal filter is filled with heterogeneous filter material.
EFFECT: providing a possibility of filter refilling of the trench of the adit; improving hydrological action of adits and ecological and economic efficiency of draining of low-water-permeable middle and heavy loamy and clay soils.
