Abstract

The utility model relates to the field of construction of permanent engineering structures on roads. In particular, it can be used for arched viaducts and pedestrian walkways assembled from corrugated metal structures constructed by means of forcing through existing embankments of highways. The technical task of the utility model is to develop such a corrugated sheet structure that is capable of completely filling the gap between the concrete mixture the surface of the arch of the overpass and the soil of the embankment formed during the development of the soil in the process of forcing the arch of the overpass through the creatures This can be solved due to the fact that the corrugated sheet with pipes, which is a convex-concave element with corrugations, differs in that on its internal (concave ) the surface between the crests of the corrugations there are several tubular nozzles freely inserted into the holes arranged in the sheet and rigidly attached to the sheet by bolts, while through the control holes are drilled in the sheet, the diameter of which exceeds the diameter of the wire probes.

Description

The utility model (hereinafter referred to as PM) relates to the field of construction of permanent engineering structures on highways. In particular, it can be used for arched overpasses and pedestrian walkways, assembled from metal corrugated structures (MGK), constructed by way of forcing through existing embankments of roads [1, 2, 3].
It is known that various facilities are being built from MGK on roads and railways [2].
The main element of the CIM is a corrugated sheet, which is a convex-concave structure with corrugations of a certain height.
Such a sheet is adopted as an analogue of PM. Gofrolists are widely used, for example, for the assembly of tunnel-type arch viaducts under embankments of various heights. [2]
When such overpasses are arranged by forcing through an existing embankment of a highway, a gap (void) is formed between the arch surface and the embankment ground. This gap should be filled, for example, with concrete mixture in order to prevent subsidence of the roadway. Filling the gap is carried out mainly by winding into the gap of a flexible concrete pipe, through which the concrete mixture is supplied under pressure. The mixture, spreading from top to bottom on the surface of the arch fills the gap. At the same time, the end of the hose is gradually moved from the middle of the overpass to its heads, thereby ensuring that the gap is filled with concrete.
However, the use of existing corrugated sheets with this method of filling a gap with a concrete mixture makes it difficult to guarantee full filling of the gap due to the presence of corrugations and depressions between them on the sheets, especially with a significant length of the overpass. At the same time, it is practically impossible to control the presence of concrete in the gap in various parts of the arch.
The technical task of PM is to develop such a corrugated sheet construction that is able to completely fill the gap between the surface of the overpass arch and the soil of the embankment formed by the concrete during the process of forcing the arch of the overpass through the existing embankment of the highway, as well as to monitor the presence of concrete in the gap in various sections along the length of the overpass.
This technical problem is solved due to the fact that the corrugated sheet with nozzles, which is a convex-concave element with corrugations, is characterized in that on its inner (concave) surface between the ridges of the corrugations there are several tubular nozzles freely inserted into openings arranged in the sheet and rigidly bolts attached to the sheet, while through the test holes are drilled in the sheet, the diameter of which exceeds the diameter of the wire probes.
The proposed design of the corrugated sheet with nozzles is shown in the figure, where it is indicated:
FIG. 1 - General view of the corrugated sheet; FIG. 2 - the position of the pipe; 1 - corrugated sheet; 2 - nozzles; 3 - concrete hose; 4 - a collar ;. 5 - bolts with washers; 6 - soil embankment; 7 - concrete filling the gap; 8 - holes for assembly bolts; 9 - control holes.
PM is made and used in the following sequence.
Typical corrugated sheets are equipped with nozzles at the factory or in a mobile workshop on the assembly site (Fig. 2)
The number of nozzles and control holes in the sheets is determined by calculation depending on the strength and workability of concrete. From ready-made corrugated sheets (Fig. 1), links (or sections) are assembled on the assembly site, of which the length of the arch is gradually increased as it is pushed.
The technology of the method of forcing, for example, lining tunnels, culverts, collectors, etc. is known [1].
Since the task of the PM is the design of the corrugated sheet, a description of the process of forcing the arch of the corrugated sheets in the text of the description of the PM is not given.
After completion of the process of forcing the arch under both its ends, concrete foundations are arranged according to the design of the overpass.
After the concrete has set the foundations of the calculated strength, the concrete hoses 3 are mounted and fixed on the nozzles 2, fixed with clamps 4 (Fig. 2) in such a way that the concrete mixture 7 fills the gap from the bottom up and from the middle of the arch to its heads (portals) simultaneously from both sides of the arch to prevent distortion of the arch. The presence of concrete mixture in the gap and the layer thickness is controlled by wire probes through the control holes 9.
Thus, the proposed design of the corrugated sheet with nozzles ensures complete filling with concrete mixture of gaps between the surface of the arch of the overpass and the soil of the embankment under pressure with the device of the road overpass from the MCC elements by forcing through the existing embankment of the highway. At the same time, it is also possible to control the completeness of concrete filling the gap along the entire length of the arch of the overpass.
