Description

The invention relates to modular construction. In particular, the invention is an improved modular system for constructing the foundations of an overhead line support and / or support pile.

Existing systems for the construction of foundations for the support of an overhead line and / or support pile create the foundations completely in place by the following steps: manual or mechanical excavation, positioning of the concrete pipe, manual pouring of concrete, installation of the pile by mechanical means.

The main difficulties in using this system are: mismatch of the centers of the concrete pipe and the base of the foundation, non-observance of the distance between the excavation in the soil and the base of the concrete pipe, which reduces the installation depth of the pile in the soil; difficult quality control of concrete, which is usually prepared on site or purchased from the manufacturer and transported to the construction site; possible displacement of the concrete pipe due to the outflow of concrete from it; difficulty squaring the walls of the base of the foundation; possible occurrence of defects in the surface of the base due to the formation of slopes that interfere with rainwater runoff.

These problems, although in other industries, are partially resolved in US patent applications No. 6178714 and 2004000114.

US Application No. 6178714 relates to a system for the construction of a removable modular structure consisting of a flat concrete base with holes spaced at regular intervals into which vertical columns and / or columns are inserted and fixed; a number of blocks of standard size, each of which has one or more fixing holes; a number of fixing columns or racks, which in their installed state are a fixing element for assembling subsequent blocks, as a result of which a wall is created for which there is no need to use concrete and which is easily dismantled.

US application No. 2004000114 relates to a modular system for block construction, which is a semi-finished product having several internal channels. Semi-finished products can be made of plastic and filled with concrete or steel reinforcement to make foundations, foundations, beams, walls and roof.

But the well-known construction methodology and the two patent applications mentioned do not eliminate the mentioned disadvantages.

The objective of the invention is to provide an improved modular system for the construction of the foundations of the support of the overhead line and / or supporting piles, aimed at solving all problems and eliminating all the shortcomings of existing systems.

In particular, the improved system is aimed at implementing the method of building the foundation, which provides increased efficiency due to the fact that it is made less susceptible to uncontrolled changes that occur during the installation stages and create the mentioned difficulties.

The problem is solved due to the fact that the modular system for constructing the foundations of the support of the overhead line and / or supporting piles contains three types of ready-made modules (A, B, C) and round steel reinforcement (D), moreover, type A module is a ready-made unit, used as a base for modules B and C, having four holes located one at each corner, for mounting the fixing fittings of the finished block, restoring the solidity of the block itself, and having recesses for the jack necessary to move the module, type B module is a ready-made block used as the top layer for type A module, while type B modules are used in sufficient quantity to provide the depth of foundation required depending on the pile being mounted, and type B module has four holes located one at a time in each corner, for mounting the fixing fittings of the finished unit, restoring the solidity of the unit itself, and has recesses for the jack necessary to move the module, as well as a central hole for mounting with and underground cable channels, the Type C module is a finished block located on top of the surface of Block B, the Type C module has four holes located one at each corner to mount the fixing fittings of the finished block, restoring the solidity of the block itself, and has recesses for the jack necessary to move the module, as well as a central hole for mounting piles and a surface slope for rainwater drainage, while the steel reinforcement contains round elements that They are inserted into each corner hole of modules A, B and C, and each element is then fixed by filling the hollow space with an expanding mortar with a high degree of adhesion and which is pumped under low pressure to fix all the block layers by uniting the module and restore solidity of the block itself.

Preferably, the modular system for constructing the foundations of the overhead line support and / or support pile has the full versatility provided by the composition and combination of the required number of ready-made type B modules corresponding to the technical requirements for the foundation according to the type of pile used.

More preferably, the modular system for constructing the foundations of the overhead line support and / or support pile has a guaranteed centering of the support and / or pile with respect to the foundation block.

In addition, a modular system for constructing the foundations of the support of the overhead line and / or supporting piles can be made with the possibility of regulating the depth of introduction of the supporting piles.

Additionally, a modular system for constructing the foundations of the support of the overhead line and / or supporting piles can be made with the possibility of using piles made of reinforced concrete, galvanized sheet, wood, polymers.

In more detail, the present invention consists of three types (A, B, C) of finished modules having different geometric characteristics and which can be performed on different samples in accordance with all the requirements for the construction of the foundation according to the type of pile and steel reinforcement used for fixing completed base layers and restoration of solidity of the foundation blocks. The construction characteristics of the mentioned modules are listed below.

- Type A module: the finished block, used as the base for modules B and C, has four holes (one in each corner) for mounting the fixing fittings of the finished block, restoring the solidity of the block itself; and has recesses under the jack necessary to move the module.

- Type B module: a prefabricated block used as the top layer for a type A module. Type B modules are used in sufficient quantities to provide the foundation depth required depending on the pile being mounted. The type B module has four holes (one in each corner) for mounting the fixing fittings of the finished block, restoring the solidity of the block itself, and has recesses for jacks needed to move the module; and a central hole for mounting piles and underground cable channels.

- Type C module: prefabricated unit used on top of a unit protruding above the surface. A type C module has four holes (one at each corner) for mounting the fixing fittings of the finished block, restoring the solidity of the block itself, and has recesses for the jack necessary to move the module; central hole for mounting piles and surface slope for rainwater drainage.

- Steel reinforcement: round elements inserted into each corner hole of modules A, B and C. Each element is then fixed by filling a hollow space with an expanding mortar, which has good adhesion and which is pumped under low pressure to fix all layers of the blocks (“uniting the module ») And restore the solidity of the block itself.

The main distinguishing feature of the invention lies in its modularity, which, thanks to the preparation of the foundation from the finished elements, improves and simplifies its construction compared to the methodology carried out on site. The invention provides the possibility of building block foundations with high technical and quality characteristics and solves all problems and eliminates all the difficulties of the prior art.

Advantages of the Invention

1. The complete modularity of the invention, due to which, by applying the required number of ready-made modules, it is possible to provide the required foundation depth, consistent with the pile being mounted.

2. High technical and quality characteristics of the foundation block.

3. Convenient mounting, providing the ability to center the piles and perform the necessary slopes to drain rainwater.

4. Regulation of the depth of introduction of the supporting piles.

5. Scientific quality control of concrete used for a modular structure manufactured directly at a concrete plant.

6. The absence of problems associated with the aging of concrete.

Concrete can be considered “matured” only 28 days after concreting, and therefore all stresses that adversely affect the foundation block before the expiration of these 28 days can cause a violation of the concrete elements.

7. No time required to wait for concrete to cure.

8. Delamination of inert materials is not required.

9. The problems caused by the construction site have been fixed, as the quality of the foundation block made on an uneven place is the same as the block made on a flat plane.

10. Reduced construction time

These advantages are explained in the description of the accompanying drawings below.

The invention is illustrated in the drawings,
