RU188707U1 - TEMPORARY ANCHOR OF ANCHORING A DIVERTING UNIT AT THE PRESS MOVEMENT OF THE FLIGHT STRUCTURES OF ROAD PASSAGE BRIDGES - Google Patents

Abstract

The utility model (hereinafter referred to as PM) relates to the field of temporary workstations. It, in particular, can be applied when sliding over AWM span structures, for example, CARM-M.The PM’s technical task is to develop such a construction of a temporary anchor for securing an anchor block when sliding an AWG span type structures (CARM-M type) that will ensure sufficient anchor stability at the same time, it will consist of a smaller number of similar inventory elements of an AWP property and will make it possible in certain cases to exclude the use of specialized equipment (such as UZS, UCA-2), thereby increasing the pace of the device the bridge of the automated workplace (SARM-M type) on the transition axis. This TZ is solved due to the fact that the temporary anchor for securing the tap-off unit when sliding the span structures of the road collapsible bridges (SARM-M type) consists of three inventory driven anchor seals, that the spikes are combined into a rigid structure with two laying channels laid on the lining bars and interconnected with tightening bolts installed in pairs outside each pile, and the bypass unit is fixed to the middle pile by an annular sling.

Description

The utility model (hereinafter referred to as PM) relates to the field of temporary workstations. It, in particular, can be applied when sliding the spans of an automated workplace, for example, SARM-M (Medium road collapsible bridge modernized (CARM-M). Technical description and operating instructions. Moscow. Voenizdat. 2002) [1].

A known construction of a temporary pile-screw anchor with a bolt stop (Temporary pile-screw anchor with a bolt stop. Patent for utility model No. 171759. Registered on 06/15/2017. Bulletin No. 17) [2]. This anchor is adopted as a prototype of the proposed PM. The main disadvantages of the prototype are:

excessive bearing capacity of the anchor, sometimes not demanded when performing certain tasks;

simultaneous ineffective use of the inventory screw pile, additional link (set-up) and two anchors from the SARM-M property in its design [1];

the need to use for installation of this anchor specialized installations for the driving of piles (UZS, UCA-2);

the complexity of the device in the cramped conditions of the assembly site.

The technical task of the PM is to develop such a construction of a temporary anchor for securing the tap-off unit when sliding the AWS span structures (of the CARM-M type), which will ensure sufficient stability of the anchor, while it will consist of a smaller number of inventory elements of the AWP property and will allow in certain cases to exclude the use of specialized equipment (such as UZS, UCA-2), due to which the rate of arrangement of the bridge of the automated workplace (SARM-M type) on the transition axis will increase.

This TZ is solved due to the fact that the temporary anchor for securing the tap-off unit when sliding the spans of road collapsible bridges (of the CARM-M type) consists of three inventory driving anchors, the welds are combined into a rigid structure with two laying channels laid on lining bars and interconnected tie bolts installed in pairs outside each pile, and the tap-off unit is fixed to the middle pile by an annular sling.

The proposed design of PM and its elements are depicted in the figure, where it is indicated: FIG. 1 - a general view of the anchor without a withdrawal unit; FIG. 2 is a side view of the anchor and the position of the diverter unit; FIG. 3 is a view of the anchor with a branch block on top; pos. 1 - anchor pile; pos. 2 - lining bar; pos. 3 - laying channel; pos. 4 - coupling bolt with nut; pos. 5 - ring sling; pos. 6 - tap-off unit; pos. 7 - sling pin; pos. 8 - hole for slinging pin; pos. 9 - traction rope.

PM and its device on the assembly site is made in the following sequence. At the selected location for the anchor device, after centering work, three splices 1 are driven in (Fig. 1 and 2). On the lining bars 2, two laying channels 3 are installed, fastened to the piles 1 by tightening bolts with nuts 4 (Fig. 1, 2 and 3). Under the paired laying channel 3 for the middle pile 1, an annular sling 5 is put on. Then the tap-off unit 6 is connected to the annular sling 5 (Fig. 3). To do this, the slinging pin 7 is removed from the hole 8 of the cage of the block 6. A loop of the ring sling 5 is inserted into the space between the sidewalls (cheeks) of the block 6 and the trailing rope 9 is inserted into the cage of the diverter block. woman "manually the composition of the calculation. Pile driving is allowed both vertically and obliquely with an angle of up to 10 °, in the direction opposite to the applied pulling force.

Thus, the proposed PM provides sufficient stability of the anchor when sliding the superstructures of the automated workplaces, while reducing the number of types of inventory elements of the bridge to two and in certain cases, will release specialized equipment, without a significant increase in labor costs and time to build anchor.

It is assumed that this temporary anchor will increase the rate of assembly of road collapsible bridges up to 5%.

Claims (1)

Temporary anchor for fixing the tap-off unit when sliding the spans of road collapsible bridges, consisting of three inventory driven anchor welds, characterized in that the welds are combined in a rigid structure with two laying channels laid on the lining bars and connected to each other by tightening bolts installed in pairs each side pile, and the bypass unit is fixed to the middle pile by an annular sling.
