(57) Abstract:

Usage: the construction of a closed horizontal drainage in the irrigation zone. The essence of the invention: in the bunker of granolithic consistently are two vertical rods. At first in the direction the rod is fixed loosening milling elements, and the second sealing screw elements. Both rods are mounted on a common rod. 1 Il.

The invention relates to irrigation and drainage construction and can be used, in particular, the construction of a closed horizontal drainage in the irrigation zone.

A device for soil compaction and drainage backfill including rack with step offset in the vertical plane of the sealing elements, at this hour, and sealing elements are installed at an obtuse angle to the direction of movement, the sealing elements are in the form of wedges, side faces (leaf) which is mounted a hinged and spring-loaded one with respect to another.

The disadvantages of this device are uneven soil compaction and poor performance due to the large frontal resistance, movement of the device.

The disadvantage of this device is the low productivity associated with the need for layer-by-layer sprinkled soil and seal.

The purpose of the invention is the improved performance of the sealing device by loosening and seals throughout the depth of the trench.

This objective is achieved in that the working elements of the device for soil compaction drainage trenches consist of two vertical rods located outside the hopper granolithic and mounted on the deadlift, and the first movement of the rod is provided with a loosening milling, elements, and the second sealing screw elements, sealing is carried out along the entire depth of the first trench by pre-grinding of the soil, then move it up and down while forward movement of the device along the trench.

Unlike the prototype, the proposed device loosening and sealing work items are located in the vertical plane, allowing the seal layers, and throughout the depth of the trench.

When comparing the proposed device with the prototype can the technical solutions such signs were found, that allows to make a conclusion about the adequacy of this invention, the criterion of "substantial differences".

The drawing shows a General view of the device for soil compaction and drainage trenches.

The device includes a base machine, such as granolithic with the hopper 1, which has upper and lower links 2. The lower rod ends of the jacks, in which the bearings in the vertical plane coaxially installed two rods; one with a milling elements 3 and the other with a screw elements 4. Top link end gear 5 with the actuator 6 from granolithic. With gear 5 connected to the upper part of the rods.

The device operates as follows.

When laying drainage lines in the ground 7 backfill using a belt conveyor 8 is fed between the feed hopper of granolithic and device for sealing.

From the practice of construction of drainage in water-saturated soils it is known that the backfilling has a lumpy shape, trudnootdelema compaction due to the formation of voids and cavities.

In the process of movement of granolithic through the actuator 6 and the gear 5 is the rotation of the work items. Rod with milling the cavity of the trench. In addition, it significantly reduces the resistance of the soil to promote the device. Rod with screw work items 4 way reverse rotation moves the crushed soil down to the bottom of the trench uniformly compacting it around the section of the trench. To eliminate thrust of the work items in one direction, they rotate towards each other.

The proposed device for compacting soil drainage trench is mounted working body, allowing you to use it as a complete with genocidical and other basic machine (tractor, and so on). The device operates by the method of rotation of the work items in a vertical plane, which allows the process seal continuously around the profile of the trench during the movement of the device along with the speed, not inferior to the speed of granolithic.

DEVICE FOR COMPACTING SOIL DRAINAGE TRENCH that includes the basic machine with work items, characterized in that, to improve performance by tilling the soil and seal along the entire depth of the trench, the device is provided with a hopper granolithic, work items are made in the form of two vertical stge, the first installed along the rod from loosening milling elements.

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.
