Description

FIELD OF THE INVENTION

The present invention relates to a prefabricated screw pile having an adjustable height depending on specific requirements and conditions and which is therefore extremely convenient for use. The declared prefabricated screw pile can be used to fix the foundations of any type of buildings and structures, power lines and other structures, especially on marshy areas, unstable or flooded soils (embankments, piers, moorings, bridges), as well as in the construction of temporary or light structures (fences )

The present invention also relates to a screwdriving device for a prefabricated screw pile having a low height and therefore extremely convenient for use.

In addition, the present invention relates to a method for screwing a prefabricated screw pile, in the course of which the full advantages of the above-mentioned prefabricated screw piles and a screwing device for a prefabricated screw pile are fully exploited.

State of the art

Nowadays, solid cast one-piece screw piles are used everywhere, the height of which usually reaches several meters. In this regard, there are many problems and inconveniences associated with their application. Firstly, for the transportation of the above solid piles in most cases, lengthy trucks are needed, which complicates the transportation and increases its cost. Secondly, it is very difficult in advance, even before deepening (screwing) the piles, to accurately determine the necessary height (i.e., the length, when the piles are in a horizontal position) of the aforementioned solid piles, which often necessitates cutting off parts of the piles that are not resistant further screwing and protruding above the surface of the earth. Thirdly, the cost of the above solid cast piles is quite expensive due to the need to use special equipment for long products for their manufacture. Fourth, the screwing process of the above solid cast piles is extremely inconvenient and labor-intensive due to the need to use special equipment that allows piles to be impacted from a great height. Fifth, the above solid cast piles have a significant mass, which also complicates the process of installing them and, for the same reason, are not safe for workers.

The applicant does not know the patents of the Russian Federation for an invention or utility model in which prefabricated screw piles would be disclosed, which would allow to eliminate the above drawbacks and possess a high degree of reliability.

In connection with the implementation of screw piles, solid and integral, for their burial in the ground, a wide variety of special equipment is currently being used everywhere, including those installed on the basis of trucks. At the same time, the possibility of screwing the aforementioned whole-cast piles manually or using simple, low tools is practically excluded for the reasons mentioned above: first of all, due to the high height and mass of the piles.

The applicant does not know the patents of the Russian Federation for an invention or utility model in which convenient and low (or not requiring raising to a high height) screw pile screwing devices would be disclosed, which greatly facilitate the process of deepening piles of any height.

In connection with the implementation of screw piles solid and one-piece, the methods of their deepening into the ground involve screwing the entire pile into the ground immediately, even if the pile height is extremely large, which causes a lot of inconvenience and is inefficient, unsafe and takes a lot of time.

The applicant does not know the patents of the Russian Federation for an invention or utility model in which quick, convenient and safe methods of screwing screw piles of any height would be disclosed.

The implementation of the invention

A prefabricated screw pile according to the present invention includes a barrel 1 and at least one blade 2. The prefabricated screw pile is made of steel or any other suitable material. The barrel 1 consists of a group of elements sequentially mounted on top of each other, which contains end elements 3 and intermediate elements 4. As a rule, two end elements 3 are used: lower and upper. The number of intermediate elements 4 is not limited to any particular number and is selected based on specific requirements and conditions, as well as on the basis of the convenience of the process of screwing a prefabricated screw pile into the ground or any other surface.

The diameter of each intermediate element 4 preferably lies in the range from 38 mm to 114 mm, but may also go beyond it. The height of each intermediate element 4 (the length when it is horizontal) for the convenience of transportation, assembly and deepening of a prefabricated screw pile is preferably equal to 1000 mm (1 m), however, it can have another value. The diameters of the intermediate elements 4 of the parts 7 of the lower and upper end elements 3 also preferably lie in the range from 38 mm to 114 mm, however, they should allow the intermediate elements 4 to be mated with the corresponding counterparts of the 7 end elements 3. The diameters of the responses of the intermediate elements 4 of the 7 parts of the lower and the upper end members 3 may extend beyond the above range. The diameter of the blade 2 in its widest part preferably lies in the range from 120 mm to 300 mm, however, it may also go beyond it. A prefabricated screw pile may contain at least one blade 2, for example, on the lower end element 3, however, in the particular case, at least one intermediate element 4 can also be provided with at least one blade 2. The lower end element 3 is made at most of its height in the form of a vertical cylinder and contains a pointed and / or cut at an acute angle tip 8 for better screwing a prefabricated screw pile into the ground.

The upper end element 3 contains a response to the intermediate element part 7, made in the form of a vertical cylinder. In addition, the upper end element 3 comprises a group of stiffening ribs 9 for increasing the structural strength and a connecting flange 10 provided with a group of connecting holes 11 for connecting to an object supported by piles. The stiffening ribs 9 are preferably made in the form of flat trapezoidal or triangular plates (or plates of a similar shape) and are mounted vertically and evenly throughout the entire diameter of the cylinder. The connecting flange 10, which is a flat rectangular plate, is installed horizontally and on top of the cylinder. The overall height of the upper end member 3 is preferably 103 mm, but may have a different meaning. The length of the connecting flange 10 (which is the width of the upper end element 3) is preferably equal to 200 mm, however, it may have another value.

Each of the end elements 3 and each of the intermediate elements 4 is provided with a group of connecting holes 5. The connecting holes 5 in the intermediate elements 4 are preferably made in the amount of two pieces from each end and from each side (two sides) of the intermediate element 4. Thus , preferably, the number of docking holes 5 in one intermediate element 4 is eight. The connecting holes 5 in the end elements 4 are preferably made in the amount of two pieces at one end, but on each side (two sides) of the end element 3. Thus, it is preferable that the number of connecting holes 5 in one end element 3 is four. The fixation of the end elements 3 relative to the intermediate elements 4 occurs by means of fasteners, which are placed in the docking holes 5. As a means of fastening, any suitable means can be used: screws, bolts, screws, nuts, washers, etc.

Each intermediate element 4 is made of two mounted on top of each other vertical cylinders 6 of different diameters. This is necessary for easy installation of the cylinder 6 with a smaller diameter in the cylinder 6 with a large diameter to obtain a reliable connection of the cylinders 6 with each other. The connecting holes 5 in the intermediate elements 4 are preferably located in the same quantity on the cylinder 6 with a smaller diameter and on the cylinder 6 with a larger diameter. In each intermediate element 4, the height of the cylinder 6 with large diameters is preferably substantially (several times, for example 5-15 times) greater than the height of the cylinder 6 with a smaller diameter.

Prefabricated screw pile is assembled as follows. Already at the place where the piles are buried, the necessary number of intermediate elements 4 is installed on the lower end element 3 by means of fasteners, depending on the specific requirements and conditions of the work, as well as on the convenience of screwing the pile into the ground. After the piles are finally screwed onto the intermediate element, which turned out to be the upper one, the upper end element 3 is installed. For transportation of prefabricated screw piles, an ordinary truck of small or extra light capacity, and in some cases a car, is suitable. This is due to the fact that the piles from the moment of production and until the last element is buried in the soil are in a disassembled state.

The screwing device of the aforementioned screw pile assembly according to the present invention includes a housing 12, a pile fixing mechanism 13, a pile screwing mechanism 14 and a group of handles 15. The screwing device of the aforementioned screw pile assembly is characterized by the convenience, ease and depth of penetration of the pile due to the low height of the device itself and due to the lack of the need to raise it to a great height in connection with the prefabricated design of a screw pile. The housing 12 is the connecting link of the remaining elements of the device. Namely, a pile fixing mechanism 13 is attached from below to the housing 12, which can be made in the form of a sleeve, a coupling, a cartridge, or any other mechanism suitable for holding the pile, including a clamping mechanism. The pile fixation mechanism 13 comprises an opening that can be used to fix the prefabricated screw pile using fastening means. The upper part of the pile fixation mechanism 13 can be made in the form of a rotating axis, shaft, spindle, inseparably connected to the housing 12. The pile fixation mechanism 13 is equipped with all the elements necessary for holding the pile. On the housing 12 or partially in the housing 12 there is a pile screwing mechanism 14, which contains a light but strong worm gear (with a gear ratio, for example, 1 × 100) using a worm gear, and all the elements necessary for screwing the pile, for example, a drive ( for example, hydraulic drive), engine (motor), drill, hammer drill, winch, transmission, carriage, control unit and any other auxiliary equipment. On the sides of the housing 12 are mounted horizontally oriented handles 15, designed to create torque by acting on them by workers. The screwing device of the above-mentioned prefabricated screw pile can be twisted manually, as well as screw the existing pile. As a device with a worm gear today, this device is the only handheld compact device in the world for a drill, hammer drill or other manual rotary tool for wrapping piles. In terms of manufacturability and cost, the claimed device should become the most affordable in the world. The device has a small mass and is affordable.

The screwing device of the above assembled screw piles according to the present invention operates as follows. Mounted on top of one another or one element 3, 4 of the barrel 1 of a precast screw pile is inserted into the pile fixing mechanism 13. The workers create a torque by rotating the arms 15 and the screwing device of the above-mentioned assembly of the screw pile by means of a worm gear carries out the process of screwing the pile. The screwing device of the aforementioned screw pile assembly is universal, because and allows you to screw piles of any final height in any way: through the mechanism of screwing piles or manually.

The method of screwing the aforementioned prefabricated screw pile according to the present is characterized by the speed, convenience and safety of screwing a prefabricated screw pile. This is achieved due to the possibility of adjusting the height of the prefabricated screw pile by sequentially installing each other the necessary number of elements 3, 4 of the trunk 1 of the pile. Moreover, the adjustment of the height of the piles can be made before screwing the prefabricated screw piles. For example, initially, for screwing in, choose one lower end element 3 of the shaft 1 of the pile, having a length of only 1 m, and almost completely bury it in the ground, then install an intermediate element 4 on it, which also has a length of only 1 m) and almost completely bury it into the ground, after which the required number of times is repeated this stage and, finally, the upper end element 3 is installed and buried in the ground. In this case, the adjustment of the pile height can be made after partial screwing of the prefabricated screw pile. For example, in the event that the initial choice of the number of elements 3, 4 for screwing was inconvenient, inefficient, you can either add or remove one or more intermediate elements 4.
