Description

The invention relates to the field of construction and concerns the construction of concrete structures with wall drainage of their underground part.

The purpose of the invention is to simplify the method for performing the concrete structure with drainage elements.

FIG. 1 shows a concrete structure made by the proposed method (an embodiment of the ribs with transverse protrusions adjacent to the water-permeable sheet), plan; in fig. 2 - the same, (an embodiment of the ribs with transverse projections adjacent to the permeable sheet and the concrete structure); in fig. 3 - the same (an embodiment of the ribs with transverse protrusions spaced from the permeable sheet).

The concrete construction of the proposed method is carried out using formwork panels and drainage elements, each of which includes a permeable sheet 2 with longitudinal ribs 3 made with anchor heads 4 fixed in the concrete structure 5 (for example, the underground part of the building, structure) in the process its concreting, and with transverse ribs 6, designed for installation of formwork panels 1 in the period of concreting of the structure.

The drainage element can be made of a polymeric material (polyethylene, polyvinyl chloride, polypropylene, etc.) by pressing, extrusion, or some other method of processing thermoplastic polymeric materials.

The permeability of the sheet 2 can be achieved by its perforation followed by the device, if necessary, to prevent possible clogging of the perforations of the geotextile material.

In the manufacture of precast elements of reinforced concrete and concrete structures of underground parts of buildings and structures, the drainage element with pre-installed formwork panels 1, fixed with ribbed ribs 6, is installed in the formwork form, intended for the manufacture of precast concrete structures or reinforced concrete elements of the building structure, so that the permeable sheet 2 faces the shape pallet. The formwork panels 1 can be made of sheet metal, pressed waterproof plywood, etc.

The formwork is then filled with concrete and the molded product goes through the usual manufacturing steps. After the molding has been completed, the product is dismounted and the formwork shields are removed 1. The flexibility of the drainage element and its fins, as well as the lack of adhesion of the polymer material to concrete, this operation does not present technological difficulties.

Another possible option for the manufacture of prefabricated elements is the insertion of the anchor heads 4 into the outer layer of freshly laid concrete products, followed by observing the usual technological cycles of its manufacture. In this case, the transverse ribs are limiting, preventing excessive embedding of the anchor heads in freshly laid concrete and guaranteeing the necessary clearance between the water-permeable sheet 2 and the concrete surface of the structure to be protected.

In this case, the construction of the drainage wall under construction conditions with the use of prefabricated prefabricated elements coincides with the usual installation of the bearing part of the underground part of the building (structure) of the prefabricated elements, which virtually eliminates the labor costs for the construction of the drainage wall under the conditions of construction production and reduces construction costs.

During the construction of the underground part of buildings and structures made of monolithic reinforced concrete, drainage elements with shuttering boards 1 inserted into them are installed from the outside of the building and perform the functions of external formwork. Formwork for concreting the inside of the structure is performed by conventional methods, as well as subsequent concreting of the structure.

After the concrete has gained the necessary strength, the internal formwork is removed and the formwork panels 1 are dismantled. In this case, the drainage wall is performed simultaneously with the concreting of the supporting structure, which will significantly reduce the complexity of the work on its design.

The proposed method will significantly reduce labor costs in the construction of underground structures and the device of the drainage walls.
