SU643091A3 - Stock multideck trench lining for laying pipelines - Google Patents

Description

can be trimmed together with the uprights: the already installed struts of the overlying walls prevent this. When dismounting the support, the disassembly of its elements (side plates of fastening trench walls, struts, vertical posts of box-shaped cross section) can be done only from top to bottom, which significantly complicates the work, as it requires additional measures to keep the walls of the trench from collapse.

The aim of the invention is to simplify the installation and disassembly of the lining.

This is achieved by the fact that in the proposed rack, each rack on its side, facing the inside of the trench, is equipped with rigidly connected vertical guide elements for interacting with the strut shoes, and the posts of the underlying Rus are equipped on the side around the trench. zannymi with racks guiding elements, while the guiding elements of the racks of the Lower Russ in the side facing the walls of the trench, are placed on at least partial stretch of the racks. The lower ends of the uprights of each overlying Rus can be located below the top of the uprights of the adjacent downstream Rus and are rigidly connected to each other.

FIG. 1 shows the proposed inventory of many Russian lining trenches for laying pipelines, the cross section along the trench wall; in fig. 2 - the same, the cross section of the rack overlying Rusa; in fig. 3 - the same, the cross-section of the rack nizhelyosch gb ps cs. ::;:,,; . . /. ; ; Inventory Many Russian crotch trenches for laying pipelines in each Russian have two rows and two pairs {one level against another vertical posts of the first box cross section, with spacers 2. Each side of the vertical posts 1, facing the adjacent rack of the same row, is provided the guide 3. In the guides 3 are mounted with the possibility of vertical movement of the side plates 4 of the fastening of the walls of the trench. Racks 1 of each tusk, on their side facing the inside of the trench, are provided with rigidly connected vertical Guiding Elements 5 for interacting with the shoes 6 spacers 2. Racks 1 of the underlying Rusa are fitted on the side facing the trench walls tightly connected to the racks 1 guiding elements 7, while the guiding elements 7 of the uprights 1 of the lower rio rio side facing the walls of the trench are placed on at least a partial extension of the uprights 1. The lower ends of the 8 uprights 1 of each

the overlying tusk can be located below the top of the 9 vertical uprights 1 of the underlying tress adjacent to it and rigidly connected to each other.

Mounting and dismounting the inventory of many brown lining for laying pipelines is carried out as follows.

Before excavating the trench, within each rus, the vertical posts 1 of this russ are driven. In this case, the vertical posts I of the underlying light brown are pre-inserted into the vertical posts 1 of the leachable Rus and are clogged with them. Then, as the trench of each Rus develops

3 side plates 4 are lowered in the guides, secured by the trench posts. On the tre. Spacers 2 are installed at the height of each tier. To do this, the bashmaks and struts 2 are inserted from above into the guide elements of 5 vertical posts. Wherein

Initially (before driving the uprights I of the underlying rus), the function of the struts of the overlying rus is performed by the struts 2 of the underlying rus. As the vertical uprights 1 below are driven

Rusa these struts 2 are lowered together with the vertical uprights 1 in the underlying Rus, and in the overlying train are lowering struts 2 that are lowering in the guiding elements 5 and the elongated struts 1 of the underlying Rus. 5 in the upright posts of the upstream Russ. rusa At the same time, the guiding elements 7 of the vertical posts I of each underlying rus are moved in the guides of the 5 vertical posts .1 of each

overlapping Rus .;

Inventory dismantling many roof supports are leading upwards through the Rus. Good dock

Thanks to the presence of the guiding elements 5 and 7, it is possible to install the bolts from top to bottom and to dismantle them in reverse order. In addition, the guiding elements 5 allow the spacers 2 to be installed at any height within each tier; their position can be changed if necessary, and the number of braces is unlimited. All this provides a simplified installation and dismantling lining.

Claims (2)

1. Inventory of many Russian lining trenches for laying pipelines, including in each tusk two rows of pairs installed one against the other and associated with the springs vertical pillars of box-shaped cross section, each side of which, facing the adjacent rack of the same row, is provided with a guide, and side plates of fastening trench walls mounted with the possibility of vertical movement in guides of two adjacent uprights of a row, while lining adjacent along the height of the trench of the Rus is connected to each other, that, in order to simplify installation and dismantling, the supports of each trench, on their side facing the inside of the trench, are provided with rigidly connected vertical guide elements for interacting with the spreader shoes, and on the side facing the trench walls, the iron beds are provided with guide elements rigidly connected to the uprights, while the STOM guide elements of the downstairs Rus stands are located along the side facing the walls of the trench, at least partially extending the posts. 2. Inventory of a lot of Russian lining according to claim 1, characterized in that the lower ends of the vertical posts of each overlying rus are located below the top of the vertical adjacent adjacent rus and are rigidly connected to each other.
