UA147282U - INSTALLATION FOR FORMATION OF FIELD FIELDS - Google Patents

Abstract

The installation for forming pile fields includes a chute for feeding concrete mixture, a nozzle for forming piles, made in the form of a cylinder with blades, which is transmitted rotational motion. At the same time the nozzle allows to form a pile directly in soil.

Description

The useful model belongs to the field of construction, namely to methods of erecting a pile foundation.

The means of mechanization that ensure the execution of pile works are based on the implementation of a number of construction processes: impact action, indentation, drilling of various types, in particular under clay mortar, vibration, rolling, combining the rotation of the casing pipe with its simultaneous indentation, placing the concrete mixture in the borehole by by the method of a vertically moving pipe, a combination of extracting soil from a well with its fastening with a concrete mixture (the auger method), etc.

This method involves the installation of pre-made piles in the design position with the help of a special technological complex. This method is not suitable for arranging other types of piles.

There is a method of erecting a pile foundation (Patent KO 2549633 C1. Method of construction of a pile-plate foundation of a high-rise building / OJSC "Stroitelstvo Research Center" - 2013158040/03;

The disadvantage of this method is the need to install injectors in the pile frame, which makes it difficult to concretize the pile and increases the complexity of construction work. It is difficult to determine the necessary amount of injected solution in each specific case, which can lead to its overuse. With this method of injection, reliable contact between the solution and the side surface of the pile is not ensured, as a result of which the pile may not gain the design resistance on the surface of the pile.

The essence of the method is the formation of piles in the well using vibrators. The disadvantage of the device is that the high quality of the formed piles is not guaranteed. Due to the applied method of vibrovacuum of concrete mortar, it is difficult to control the thickness of the pile walls, which can lead to overspending of materials and an increase in the cost of construction.

The basis of the useful model is the task of developing an installation for the formation of pile fields. The task is solved by the fact that the installation for forming pile fields has a common feature with the closest analogue in the presence of a chute for feeding the concrete mixture, which differs in that it contains a nozzle for forming piles, made in the form of a cylinder with blades, to which rotational motion is transmitted, while the nozzle allows you to form a pile directly in the ground.

The task is solved by the fact that the installation for the formation of pile fields, containing a chute for feeding the concrete mixture, according to a useful model, contains a nozzle for forming piles, made in the form of a cylinder with blades, to which a rotational movement is transmitted, while the nozzle allows forming a pile directly in soil

The claimed device differs from the closest analogue in that, for the formation of pile fields, a pile formation nozzle is used, made in the form of a cylinder with blades, to which a rotational movement is transmitted, while the nozzle allows for the formation of piles directly in the ground, which provides during the process of piling and concrete pressing, the formation of a strong contact between the pile and the soil, makes it possible to form piles in a short time, and, thus, to arrange pile fields with a sufficiently large number of piles.

The drawing schematically shows the installation for the formation of pile fields.

The installation for forming pile fields consists of a nozzle for forming piles 1, a drill bit 2, an overlay to ensure the distance 3, a reducer 4, an electric motor 5; control panel b, chute for feeding concrete mixture 7; wheels 8, anchor 9 and frame 10.

The formation of the pile begins with the immersion of the nozzle to the bottom of the well, the rotation is turned on and a fine-grained, semi-dry concrete mixture is fed on top, which forms a pile under the compressive action of the nozzle blades. 60 The arrangement of the pile field is carried out as follows:

1. At the first stage, a well is drilled using a drill 2. 2. After the drilling process is completed, the frame 10 is moved and a nozzle for forming piles is lowered into the previously drilled well. 3. Turn on the electric motor 5 and feed the semi-dry concrete mixture through the chute 7. During the pressing process, the nozzle that forms the pile gradually rises to the surface. 4. After the formation of piles is completed, the frame 10 is moved to a new place, where the process is repeated.

The advantage of the proposed installation is that it is easy to use, allows you to increase work efficiency by accelerating the transition from drilling to pile formation. As a result, the labor intensity and time of piling field construction is reduced, which allows to reduce material costs.
