Abstract

This invention relates to the field of land reclamation. The purpose of the invention is to eliminate the additional amount of earthworks and reduce the consumption of filter material.

Upon reaching the required length, set by the project according to the groundwater level, the upper third line 7 is stopped laying. To protect against sludge, the end of the pipeline is closed with a cap. The laying of the remaining two first 3 and second 4 lines of the pipeline continues. Upon reaching the required length, the second line 6 is processed, its end is also closed with a plug 9, the remaining first line 3 is laid to the required length, after which the end is also closed with an agglume 9.

Description

eleven

The invention relates to land reclamation and can be used in the construction of closed horizontal drainage,

The purpose of the invention is to eliminate the need for additional work and reduce the consumption of filter material.

FIG. 1 shows a drainage pipe; its end is also closed by a suction pipe, a longitudinal profile; FIG. 2 is a section A-A in FIG. 1, in FIG. 3 - section. BB in FIG. 1. Method of construction closed

9. The use of a multilayer method of laying a drainage pipeline line provides the necessary water-holding capacity throughout the horizontal drainage, includes draining the drain, simultaneously trenching 1, backfilling the underlying laying technology and reducing the first layer of the filter (sand and gravel construction of drainage, mixing) 2, laying of the first line and 3 of the drainage; In addition, a multi-layered lined pipeline 4, an overhead drainage pipeline provides the filter layer 5 and through a certain 20 continuous In case of a proper gap, the second drainage work - laying the second 6, and one or two lines

further and third, 7 drainage lines; tailing 4 and backfilling 8 of the trench 1. The ends of the laid drainage lines of the pipeline 4 are closed with a bottom 9.

The method is carried out as follows.

Laying the pipeline 4 start from the mouth of the part. At the same time, all three lines of the drainage pipeline 4, backfill by filter 5 are laid at once. Upon reaching the required length, set by the project according to the groundwater level, the upper third line 7 is stopped to be laid. For silting protection, the end of the pipeline is closed with a plug 9. YesA-A

Further, the laying of the remaining two first 3 and second 6 lines of the drainage pipe 4 is continued. Upon reaching the required length, the second line 6 of the pipeline is cut off, the end of which is also closed with a plug 9. The remaining first line 3 of the pipeline is laid to the required length, after

actions at least one line.
