COATING DESIGN OF LOCALLY RECOVERED SLABS

The utility model relates to aerodrome and road construction, namely, to constructions of cement concrete coverings of runways (HW), taxiways (taxiways), parking lots (MC) locally restored due to operational damage, and can be used in the repair of damaged cement concrete sections Dodog coatings, laying new and repairing existing communications located under cement concrete coatings, as well as during joint repair of defective coating sections with simultaneous laying of sludge and repair of communications.

There are known constructions of reconditioned coatings containing bearing plates laid on the base with adjacent faces to form a repair cavity between them, filled with an insert in the form of a mixture of various constituent components. (Great Britain, patent No. 2287976AI, MKI: ЕСС 23/07 publ. 4.10.95; Germany, patent № 4237512, MKI: 23/06, 19 / 10.48, publ. 11.05.94)

The impossibility of achieving the technical result provided by the claimed technical solution is due to the fact that the installation and repair work on laying the same structures requires considerable time due to the need to set sufficient strength of the inserts placed in the repair cavity in the form of a raw mixture, which makes this design especially unacceptable during repair Runway, RD, MS due to violation of the flight schedule.

MKI6: EOlC 5/06, 7/14, 23/09

bearing plates with inclined adjacent faces diverging to the lower surface, forming a repair cavity between them with an insert installed therein with a gap relative to the faces, flush with the driving surface of at least one bearing plate and interacting by means of embedded gaskets mounted in the gap from the adjacent ny (1st faces, and the shape of the insert corresponds to the shape of the repair cavity (USSR, AS No. 1604884AI, MKI: E01C 23/09, published on November 7, 1990)

The impossibility of achieving the technical result provided by the claimed design is due to the fact that the design of the restored coating described in the prototype is not designed to restore plates with defective areas of the driving surface, including runways, taxiways, MS, as well as repair at the same time damaged sections of slabs and communications, which limits the range of applications of such a construction.

Installation in the design of the prototype liner, which is part of the restored coating itself, which has been used for some time, does not allow the restoration of plates to improve their performance and increase the durability of the coating.

In addition, in the known design, embedded gaskets fulfill the functions of supporting bridges without providing sliding of the insert, which complicates the installation of such a structure.

The need to perform inserts by cutting them along the bottom surface and cutting the side faces lengthens the repair and restoration of the coating.

When developing the claimed design, the task was to create a coating of locally reconstructed slabs, used in a wide range from pryggy runways, RD, MS, requiring restoration of slabs with defective zones, to

(/

road surfaces requiring restoration of cracked slabs with simultaneous repair of communications.

In solving this problem, a technical result was obtained consisting in the creation of a coating with block modules, which made it possible to equip the slab structures in a wide recovery range with simultaneous increases in the operational reliability and durability of the coating, as well as to simplify the installation of slabs and reduce the time for repair and restoration of coatings.

The specified technical result is provided by tagL, that the design of locally-restored plates contains at least one supporting plate laid on the base with adjacent faces forming a repair cavity between them with a liner installed in it with a gap-seam relative to the faces, flush with the driving surface, at least one carrier

plates and interacting by means of embedded gaskets mounted in

, | 1 / ve the gap with adjacent faces, and the shape of the liner corresponds to the shape of the repair

cavities.

New in the design of the coating structure is that the liner is made of at least one section of the molded block module, and the distance in plan between the upper ribs of adjacent faces located in the driving surface of at least one plate corresponds to its defective size zones in the plan, and the embedded gaskets are made in the form of sliding guide inserts with the possibility of their removal.

In addition, adjacent granite of at least one carrier plate can be made in a vertical or wedge-shaped, or arcuate planes, sections of the block modules can be equipped with fitting devices, as well as voids and ribs in the lower part, and the defective zone of the plates can be located along seams of a covering.

The construction device is shown in the drawings, which depict: FIG. 1 is a sectional view of a co-construction of two restored plates in front; FIG. 2 - the same, top view; FIG. 3 is a view of the structure of the coating of several restored plates

a plan indicating defective areas; FIG. 4 - coating design with a set of sections of block modules.

The coating structure comprises at least one, and in the represented FIG. 1 two load-bearing reinforced concrete pliggs (1) with adjacent faces (2), which could be located in vertical or, for example, wedge-shaped inclined diverging to the bottom surface of the plates and to the base (3) (Fig. 1) or arcuate, etc. planes. A repair cavity (4) is formed between the faces (2), in which a insert is installed made in the form of at least one section of a block module (5) preformed in accordance with the shape of the repair cavity (4). The insert (5) is installed with a gap-seam h (Fig. 1) relative to adjacent faces (2) of the respective plates (1).

The linear distance li (Fig. 2,3) between the ribs (6) of the faces (2) located in the driving surface (7) of each plate (1) corresponds to the linear size of the defective zone (8) (Fig. 3). In this case, the linear dimensions Imi of the block module could be smaller than the linear dimensions in the plan between the upper ribs (6) of the faces (2) corresponding to the linear dimensions in terms of the defective zone, for example, by twice the width h of the gap-joints .I

Between the block module (5) and the faces (2) of adjacent plates (1), a embedded gasket is mounted in the gaps, made in the form of a sliding guide insert (9).

If the defective zone (8) is extendable, then the liner is mounted from several sections of the block modules (5) (Fig. 4). Each block module is equipped with mounting

devices (10) and is made flush with the driving surface (7) of the plates (1), while in the lower part it can be filled, for example, with voids 11 and ribs 12.

Defective zones (8) of the driving surface (7) of the plates (1) can be located mainly along the transverse (13) or longitudinal (14) joints (Fig. 3), or, for example, in any other local place on the driving surface of the plates.

The specified design is mounted as follows:

At airports in between flights, according to the flight schedule, local areas of defective areas (8) of airfield coatings to be determined

recovery, and their linear measurements are made LI,

In the past, non-disturbing graphics of the departure of aircraft, vertical or inclined, etc. cuts are made cuts along the rectilinear contours of defective zones (8) of the coating and sliding cuts are installed in the resulting cuts

guide inserts (9), providing free-sliding dismantling of the destroyed areas to be removed. Saws are made to the lower base of plate 1. In this case, the directions of adjacent faces (2) of adjacent plates (1) turn out to be vertical, or inclined to the base, etc.

The notch & k / 1ad1shap is produced by any mechanism sufficient

lifting capacity using, for example, collet grips, or anchors with bolts screwed into them, suction grippers, etc.

The removed damaged parts of the plates are taken out of the airfield for storage or further processing. Then, in the resulting repair cavity 4, the base (3) is embossed and the molded sections of the block modules (5) brought in or formed into the cavity (4) are mounted, or one of them is provided with the specified gap width between the block module (5) and the faces (2) ) respectively.

mounting loops and so that the upper surface of the block modules is installed flush with the driving surface (7) of the plates (1). The resulting grooves (seams) after removal (removal) of the inserts (9) are sealed with sealant.

Similarly, the installation of coverings from locally reconstructed slabs is carried out during the laying of new and repair of existing underground utilities located under cement-run coatings.

The feasibility of the claimed utility model is confirmed by the use of known means (for example, equipment for cutting faces of plates of various widths and configurations described in Japan patent, MKI: E01C 23/12, No. 6057931B4, publ. 3.08.94) and non-deficient materials, including for signs presented at the level of functional generalization with the achievement of technical results, consisting in the expansion of the range of restored coatings with a simultaneous increase in their operational reliability and durability due to ichiya design blokmoduley preformed and hence neiznoschennyh, and also due to the fact that their linear dimensions correspond to the dimensions of defective coating areas, and the shape of the shape of the repair cavity. These block modules allow you to quickly replace defective or destroyed sections of plates or whole plates, including significant sizes, by installing a set of sections of block modules, which reduces the time for repair and restoration of the coating. In addition, this design allows to simplify its installation by ensuring the sliding of the corresponding elements.

And, finally, all of the above listed results in their totality ensure the safety of takeoff and landing of aircraft.
