Abstract

FIELD: construction.

SUBSTANCE: invention relates to construction and is intended for reliable and durable water-resistance of both aboveground and underground and underwater construction. Method of producing multilayer construction articles includes serial laying in form with sides of reinforcement mesh with anchor elements, concrete mixture, waterproof layer of elastic material in form of film. Vacuum pressure is created in space limited by form and film fixed to its sides. Hardening material of protective finishing layer is placed to embrace anchor elements with it. Wherein laying of concrete mixture is made separately: at first, coarse filler is supplied simultaneously with laying of reinforcement mesh, after vacuum creation hardening solution is supplied in pore space with simultaneous laying of protective-finishing layer material.

EFFECT: technical result is high efficiency of hydroprotection, improvement of strength of article.

Description

The present method relates to the field of construction and is applicable in conditions where increased requirements for the reliability and durability of water protection are required.

A separate method of concreting is known when the pore space formed by a large aggregate is filled with a hardening mortar under pressure.

("Technology of industrial construction from cast concrete." M., S.I. 1989, p. 262, under the editorship of S.S. Ataev).

The disadvantages of this method include the subsequent complexity and unreliability of water protection under the influence of groundwater.

A known method of manufacturing multilayer construction products, including sequential laying in the form with the sides of the reinforcing mesh with an equidistant mesh plane fixed on it with linear anchor elements facing the opposite side to the mold bottom, the hardening mixture of the protective-finishing layer, a waterproofing layer of elastic material with coverage and fixing it to the anchor elements and the sides of the form and creating a vacuum in the formed closed space, where to increase the bearing capacity on TIG layers provide relief in one of the layers (RF Patent № 2012489).

The disadvantages of the method include the complexity of manufacturing products experiencing shear pressure during precipitation of soil backfill, or other seismic movements of the soil.

The purpose of the invention is to reduce the complexity of manufacturing products in which shear forces act on the layers of the product during operation when moving surrounding soils, in particular seismic.

This goal is achieved by the fact that in the method of manufacturing multilayer building products, including sequential laying in the form with the sides of the reinforcing mesh with anchor elements, concrete mixture, a waterproofing layer of elastic material in the form of a film and creating a film in a space limited by shape and fixed to its sides , vacuum pressure with subsequent laying of the hardening material of the protective and finishing layer with the coverage of its anchor elements, the concrete mixture is laid separately, first coarse aggregate is laid simultaneously with the laying of the reinforcing mesh, and after creating a vacuum, a hardening solution is supplied into the pore space with the simultaneous laying of the material of the protective-finishing layer.

In FIG. 1 shows a fragment of the formwork with the image of the described solution.

A reinforcement 3 with anchor elements 4 is installed in the mold 1 with sides 2, then a large aggregate 5 is fed (here a fragment of the aggregate is shown facing the waterproofing layer 6).

After that, a waterproofing layer is supplied in the form of a film 6 with inlets 7, which is hermetically connected to the sides around the entire perimeter of form 1. A vacuum is created under the waterproofing layer 6 and form 1, under which layer 6 compresses the anchor elements 4 and is pressed against the filler layer 5 repeating its embossed surface.

Then the material of the protective and finishing layer 8 is supplied, which fixes the relief created by the layer 6, and only then the hardening solution is fed into the pore space of the filler 5 under pressure.

In FIG. Figure 2 shows an example (a little fantasizing) of using this solution when constructing a tunnel underwater using prefabricated segments 1, each of which can be 6-10 meters long, on a tunnel section 100-200 meters long.

After assembling segments 1 in underwater conditions, the ends of the tunnel are muffled, water is removed from the assembled section of the tunnel (by ensuring crimping of elastic fittings 2), and then, in dry conditions, the tunnel space is completely and guaranteed dry by folding inlets 3 of the waterproofing layer into the fold 4 and sealing it at the junction of segments according to the example, in particular, solutions known from RF patents No. 1719575 or No. 1654485, already in dry conditions.
