Adit construction method

FIELD: construction.

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.

The invention relates to reclamation construction and can be used in the construction of private collectors in the Nonchernozem zone, intended for the drainage of the medium and heavy loamy and clay soil with atmospheric and alluvial types of water supply.

As you know, private collectors disperse water from the soil surface and gravitational water from the arable layer. The backfilling of a private collector, as a rule, has a permeability higher permeability of the surrounding soil on the order and more.

Known private collector (Patent RU 2411322 C1, CL. E02B 11/00, 2011), including rainwater, an element in the form of a prism, placed in a drainage trench with vertical walls and laid in her drainage tube, wrapped protective filter material. Prism made of n-th number correct vertical longitudinal prisms, where n≥2. Prisms form a single unit. At the same time every adjacent prisms (for increased contact filtration) filled dissimilar filter material. As the filter material can be used sand, slag, linen fire, the mixture was removed from the drainage trench soil with the soil plow layer or emaciated with additives such as sand, slag, dolomite, etc.

A known method of construction W�indoor gatherers (Temporary recommendations for the design and construction of drainage structures in slabovodopronitsaemyh soils on the plots of the non-Chernozem zone of the RSFSR / group of authors; Sevdiyim-Lenmelioraciâ-Lingeroption. - L: Sevdiyim-Lingeroption, 1988. - 52 p.; prototype, p.4.2) that includes digging a trench excavator-trencher, laying in the drain pipe, wrapped protective filter material and backfilling through precipates, moving synchronously with the trencher and equipped tank filter material with drain tray, designed for feeding the filter material in the trench. While laying drainage pipe wrapped protective filter material and backfilling is carried out simultaneously.

The reasons that create difficulty in the use of this technology in the construction of private collectors, is the inability of mechanized operations in the drainage trench backfill consisting of n-number (n≥2) vertical longitudinal filter prisms. Domestic machine-building industry produces special tools and machines.

The problem to be solved by the claimed invention is the expansion of technological capabilities of equipment for the construction of private collectors - construction of private collectors, the backfilling which is not one, but n, for n≥2, a vertical longitudinal filter prisms.

The technical result of the decision delivered� task is to reduce the cost of construction by ensuring that the mechanical execution of the filtering trench filling of a private collector, having in the trench, the n-th number (n≥2) vertical longitudinal filter prisms, as well as by performing operations simultaneously on the laying of drainage pipes, powder her filter material and backfilling the trench, and, in addition, improve the hydrological action of private collectors and the promotion of ecological and economic efficiency of drainage slabovodopronitsaemyh medium and heavy loamy and clay soils.

The task is solved in that in the method of construction of private collectors, rainwater containing element in the form of a single block of n-number (n≥2) vertical longitudinal filter prisms, including digging a trench excavator-trencher, laying in the drain pipe, wrapped protective filter material and backfilling through precipates, moving synchronously with the excavator-trencher and equipped tank filter material with drain tray, and laying drainage pipes, wrapped protective filter material and backfilling is carried out simultaneously, the drain pipe, wrapped protective filter material, simultaneously with laying it in a trench, put some filter material over the entire width of the trench 15 cm above suligoi out of the box, which is a rectangular parallelepiped, having�th, width equal to the width of the trench, and the height somewhat greater than the depth of the trench, wherein the bottom of the box is placed above the bottom of the trench to the thickness of the layer of powder of the drain tube relative to the bottom of the trench, the front wall of the box is rigidly attached to the body of the excavator-trencher, and on his back the wall from the outside set (n-1) vertical, parallel to each other and the walls of the trench with the possibility of changing the distance between them in accordance with the thickness of the prism walls, the height of each of which is equal to the height of the box, in addition, the tank filter material is divided into sections by means of partitions with the possibility of changing the distance between them and their number so that the number of sections of the bunker was one more than the number of vertical longitudinal filter prisms of a private collector, with each hopper section is provided with its drain tray from which each adjacent vertical longitudinal fill the prism of dissimilar filter material. The vertical partitions mounted on the rear wall of the box with the outside of his hand, is equipped with skids at their lower end. Backfilling of the initial portion of the trench, the length of which is equal to the length of the box with partitions, produce according to specific conditions. The top of a single block of the n-th produce specific condition�th. The top of a single block of n-number (n≥2) vertical longitudinal filter prisms of a private collector on arable land is placed at the level of the plow pan plow layer, and the hayfields and pastures are placed on the soil surface.

The claimed method of construction of private collectors, rainwater containing element in the form of a single block of n-number (n≥2) vertical longitudinal filter prism, due to the expansion of technological capabilities of the equipment for the construction of private collectors allows to mechanize the perform backfilling of drainage trenches. Perform operations simultaneously on the laying of drainage pipes, powder her filter material and backfilling the trench also reduces the cost of construction of a private collector. The ability to mechanize the perform backfilling drainage trenches with water-receiving element in the form of a single block of n-number (n≥2) vertical longitudinal filter prisms will have an impact on improving the hydrological action of private collectors and the promotion of ecological and economic efficiency of drainage slabovodopronitsaemyh medium and heavy loamy and clay soils.
