SU998635A1 - Prefabricated knock-down paving for temporary roads over marshland - Google Patents

Description

The invention relates to road construction and can be used in the oil and gas industry in repair and emergency response of underground pipelines in wetland conditions. .

Known collapsible coatings are used to reduce the specific pressure from. loads on the base, which are wooden, shields of various designs, laid-. mym in the form of two tapes kolvsoprovods11

The disadvantage of such coatings is their low distribution capacity, and, as a result, low bearing capacity.

Closest to the invention of the neotechnical essence and the achieved result is a prefabricated assembly of temporary roads in the swamps, including shields with flooring made of transverse elements with longitudinal slopes and wheels laid on top of the flooring.

These coatings have low rigidity and insufficient bearing capacity and cannot bear the load when passing through windows encountered in swamps.

The purpose of the invention is to increase the bearing capacity and rigidity of the coating.

The goal is achieved by the fact that in a collapsible roofing temporary roads in the swamps, including shields with a floor of transverse elements with longitudinal lying below them and laid

10 on top of the flooring wheels, wheels and longitudinal rigs are rigidly interconnected at the ends of the matching shield shields and crimped into collapsible metal joints,

15 kgikdy of which includes the lower fixed sheet, placed under the appropriate longitudinal we lay, the rack with the lower ends, bent under the lower fixed sheet, 1 top-g

20 Scientific and Research Institutes a movable sheet placed on the appropriate wheel drive and installed with the ability of vertical movement and removable transverse stop plates supported on the upper heads of racks with clamping screws located in their center.

FIG. 1 shows the facade covering; in fig. 2 - the same plan; in fig. 30 3 - the same, cross section; in fig. 4 - collapsible metal joint. The coating consists of a transverse flooring 1, extended to the longitudinal legs 2, made, for example, from bars, wheel outlets 3 made of the same material are laid on the edges of the flooring above the extreme levels. The wheel outlets, and the lying of the mating flights, are mutually crimped at the ends by a collapsible metal joint 4, which consists of the bottom 5 and the top b longitudinal sheet, for example, a channel bar, vertical posts 7, removable transverse stop bars 8 with threaded holes 9, and clamp screws 10. To skip the wheel load, the track or continuous plank floor 11 is laid on the crossbars. The presence of a rigid junction of the mating spans is capable of transmitting a bending moment, and the mutual reduction of the lying b by wheel unloading allows init them to work together to claim composite beam principle and essential but increase the rigidity of the coating. In this case, the load is distributed to a significant number of unloaded crossbars along the length of the floor, resulting in an increase in its carrying capacity. Gesture bone coating; can be adjusted by the number of combined wheel drive and top lying along the edges of the flooring, so it can be used when going through the windows to the rails (rtsg. wine marshes of the marshes as a supporting bridge bridge span Formula of the invention from the transverse elements with longitudinal holders located under them and the wheels of the floor laid on top of the flooring, from that, in order to increase the carrying capacity and rigidity of the coating, the wheels Otoboi and longitudinal lezhny rigidly interconnected at the ends of the mating shields and crimped collapsible metal joints, each of which includes the lower fixed sheet placed under the respective longitudinal we stand, racks with lower ends, bent under the lower fixed sheet, the upper movable sheet, laid on the corresponding wheel outboard and mounted for movement, and removable transverse support plates supported on the upper heads of the racks with clamping screws located in their center.
