Description

The utility model relates to road construction and can be used, in particular, in the construction of motorways.
Known road construction [Copyright certificate of the USSR 1211373, publ. 02.15.86], including a coating laid on a soil base and longitudinal elements laid on piles, driven into the ground along the edge of the roadway. The longitudinal elements are made with bevels facing the axis of the road structure. The coating plates are made in the form of an arch supported on the base, and with longitudinal ends on the longitudinal elements. The arched shape of the tiles gives added rigidity. The main drawback of the design is its complexity, as well as the presence of joints that are subject to termination.
Known design of the roadway [RF Patent 2027822, publ. 01/27/1995], including the underlying layer of sand material through which piles are driven into the subgrade, the rows of which are located along the edges of the canvas and along its axis. Reinforcement is mounted in the tops of the piles left above the surface, on which a cement concrete coating is laid, sealed with a vibratory beam. The main disadvantage of the design is its low strength.
As a prototype, the road structure described in the patent of the Russian Federation No. 2076165 [Patent for the invention of the Russian Federation No. 2076165, publ. 03/27/1997]. The device incorporates piles driven into the ground, on the protruding ends of which reinforced concrete caps are worn. Piles are arranged in rows across the roadway. The headbands are pre-cast reinforced beams with holes, the size and location of which correspond to the size and location of the piles so that the headbands can be freely mounted on the upper ends of the piles. The molded coating slabs rest on the headgear of adjacent piles to ensure that their lower surfaces come into contact with the ground. Alignment of the level of installation of the plates is ensured with the help of trims placed on the headgear, and additional fixation of the plates is ensured with the help of bolts and fixing nuts. The asphalt pavement is laid after installation and alignment of the slabs.
The design described in the patent of the Russian Federation No. 2076165 is difficult to manufacture and causes great difficulties during installation, because when driving piles, it is difficult to achieve strict parallelism and uniformity of the protruding ends. This complicates the installation of headrests and the assembly of the road structure. In addition, it is necessary to seal joints between reinforced concrete slabs.
The utility model is based on the task of expanding the arsenal of funds, namely the creation of a road structure of high strength (load capacity), and technological in manufacture due to the fact that its load-bearing elements, except for piles, are made on site and do not require sealing joints of a reinforced concrete sheet.
The problem is solved in that the road structure includes reinforced concrete piles driven into the soil of the subgrade, the protruding parts of which are interconnected by beams, over which a reinforced concrete sheet is formed. The design differs from the prototype in that, additionally, a excavation is made in the soil filled with sand with the formation of a sand cushion, the reinforcing elements of the piling parts protruding above the level of the sand cushion are joined together by longitudinal and transverse rod reinforcing elements, on top of which the reinforcing is laid and fastened with them grid. In this case, the longitudinal and transverse rod reinforcing elements are constituent elements of grillage beams formed by pouring the mentioned rod elements with concrete mortar in the formwork pre-installed on the sand cushion, and the reinforced concrete sheet is formed by the concrete mortar pouring all the mentioned reinforcing elements and mesh with the formation of a single monolithic structure. Preferably, the thickness of the sand cushion is 10-90 cm.
A layer of asphalt can be laid on top of a reinforced concrete sheet.
In order to better demonstrate the distinctive features of the utility model, as an example, not having any restrictive nature, the preferred embodiment is described below.
An example implementation is illustrated by the Figure of the drawing, which shows a design diagram.
Before the construction of the road structure, excavation is carried out - a road trough with removal of soil to a depth of 10-100 cm.
The road structure includes reinforced concrete piles 1 hammered into the ground to a depth exceeding the freezing depth, which prevents them from being squeezed out during frost heaving of the soil. Practically piling can be from 1 to 9 meters. Piles are clogged over the trough area in longitudinal and transverse rows. The pitch of the rows of the pile field along the axis of the road is 1-5 m. The maximum distance between piles (in the transverse section of the roadway) does not exceed 1.5 m. Pile heads protrude above the level of the bottom of the trough.
A sand cushion 2 with a thickness of 10-90 cm is formed in the road trough. The reinforcing elements of the parts of adjacent piles protruding above the sand cushion are joined together using longitudinal and transverse rod reinforcing elements (not shown in the Figure). As the latter, steel rods with a cross section of 5-50 mm can be used; they are connected to the protruding reinforcing elements of the pile heads by welding or strapping. These steel rods are located in the previously completed formwork of the longitudinal and transverse beams of the grillage (pos. 3 and 4, respectively) connecting the piles. A reinforcing mesh is laid on top of the steel rods, it is fastened with them, as well as with reinforcing elements of piles. Pouring concrete formwork for the longitudinal and transverse beams 3 and 4 of the grillage and the roadway 5 itself with a steel mesh inside is carried out simultaneously, with the formation of a single monolithic structure. The height of the cross section of the grillage beams is 10–40 cm, the width is 10–60 cm, and the thickness of the canvas is 10–35 cm. A side fence can be formed along the edge of the canvas to fix the stacked asphalt layer. Asphalt paving is laid over the entire width of the reinforced slab (including the width of the curbs).
Thus, the base of the road is a reinforced structure, with longitudinal and transverse ribs formed by grillage beams resting on a pile field. A single monolithic frame has no connecting seams and does not require fitting parts during installation. High manufacturability of the construction is ensured by the fact that all structural elements (except piles) are made directly at the construction site. Prefabricated reinforced concrete structures are not used in this technology. The strength characteristics of the monolithic structure are so high that the formed relatively low sand cushion is only the basis for pouring concrete mortar, and is not a supporting element. The design works similarly to the pile-flyover structures used in the construction of bridges.
In addition, the manufacture of reinforced concrete foundation directly at the construction site allows arranging elements of road safety, as well as the fastening of the corresponding signs, road infrastructure.
