Abstract

The invention relates to foundations with a low grillage, erected on the ground, covered with water, and can be used in the construction of various structures: bridge supports, power lines. The construction of the foundation begins with the installation. The invention relates to foundations with a low grillage erected on a ground covered with water, and can be used in the construction of various structures, mainly bridge supports, power lines. The aim of the invention is to increase the bearing capacity of the foundation and to simplify the production of work during its erection in deep-water areas. guiding elements 5 along the radii of concentric circles and with their tips located above the surface of the water area, and each block 10 is immersed along the guiding elements 5 located on the same radii of different circles coinciding in direction, the blocks being installed from the bottom of the water area to the level of its surface, and after the blocks are submerged through coaxial holes 11 in them, 2 peripheral wells are made in the ground and peripheral supports are formed by filling the periphery with structural material. of the serial wells and cavities above them, formed by coaxial holes of the blocks of all Rus, then the guide elements 5 are removed and the cavity of the central well is developed through the cavity 17 formed by the inner ends of the blocks 10, followed by the formation of a central support by means of monolithic and overlying cavities with structural material and then monolithing is performed on top of the blocks of peripheral and central supports. 12 il.

Description

building elements with peripheral and central cavities; in fig. 9 - formation of peripheral wells; in fig. 10 - formation of the central well and the formation of peripheral supports; in fig. 11 - filling the central well with the formation of the central pillar of the foundation; in fig. 12 - building elements with spaced ridges with recesses.

To implement the proposed method of building the foundation, for example, from a pontoon or from any other (one or several) floating equipment 1 into the soil 2, which is under the water layer 3, the thickness of which should not exceed 100 m, guide mechanisms 4 are screwed in with the appropriate mechanisms elements in the form of metal rods 5, provided with spiral blades 6. The rods 5 are arranged in concentric circles 7 and 8, with the number of rods 5 in each of them being the same. Then the metal rods 5, the free ends of which should be located above the water surface, are fixed in a vertical position, for which using a floating craft 1 above the water surface, a jig-frame 9 is mounted, the dimensions of which are determined by the diameters of concentric circles 7 and 8. Thereafter, m 5, performing the function of guides, with the help of the watercraft 1 on the ground 2 they begin to lower the building blocks 10 made of concrete and having the form, for example, parts of a ring. Each building block is made with a through hole 11 and is equipped with two devices 12, facilitating its directional descent. The device 12 consists of a lug 13 fixed in the building block 10, a plate 14 covering the core 5, and an intermediate link 15 interconnecting the lug 13 and the plate 14. Due to the fact that each building block 10 is made as part of a ring when laying the blocks a closed ring is formed on the ground in one row (see Fig. 7). The building blocks 10, being recruited to the required height, form the basement body (see Fig. 8) with peripheral 16 and central 17 cavities, through which peripheral 18 and central wells 19 are then performed in the ground 2 (see Fig. 9. And 10) developed by known methods for the design depth. In this case, the soil 2 is developed through the peripheral cavities 16. After the zyugo well 18 and the cavity 16 of the grillage are filled with concrete, forming peripheral cavities.

foundation supports 20 (see FIGS. 9 and 10), when the required strength of the peripheral supports 20 is started, the conductor 9 is dismantled and removed from the ground

5 metal rods 5, which can be carried out in any sequence and by any known methods, in particular unscrewing with preliminary separation, for example, of an intermediate link 15

10 from the lug 13 of the building block 10. After all the metal rods 5 have been removed from the soil, they proceed to the development of the central well 19, at the end of which the well 19 and the cavity 17 of the grillage

15 is filled with concrete (see Fig. 11), forming the central support 21 of the foundation, and is molded with peripheral supports 20 of the foundation above the last row of building blocks 10. After the concrete,

20 forming the central part of the grillage and its top, acquired the necessary strength, the foundation is ready for operation. For a more precise orientation of the building blocks and, therefore, to ensure a higher foundation strength of the liver, the radially protrusions 22 and the recesses 23 can be made on the flat surfaces of the building blocks 10 (see Fig. 12).

30 When erecting a foundation on an inclined surface area, one should first prepare a horizontal platform with a diameter slightly exceeding the diameter of the foundation.

35 Foundation works as follows. The vertical load is perceived over its entire area, taking into account the formed supports. The horizontal load is perceived by the supports of the calculated

40 sections, taking into account the own weight of the foundation.

Using the construction elements of the specified form, with the application of the proposed method, you can build foundations

45 on the ground, the thickness of the water layer above which does not exceed 100m. The diameter of the foundation can reach 80-100 m, the diameter of the peripheral supports must be at least 40 cm, the thickness of the building block

50 can be practically any, and its recesses and protrusions can have a width and height of, respectively, 70-80 and 30-40 cm. The diameter of the central support of the foundation can be 50% of its diameter, and

55 diameter peripheral piles can reach 3-4 m.
