Description

one

There is a known method of construction, for example, by vibrating a stuffed pile with a wider & nyuyu well penetration and subsequent concreting with a SLIM solution using the method of a vertically moving pipe.

However, this method does not provide high labor productivity using only ONE, for example, a vibrator grab.

The aim of the invention is to increase labor productivity by using only ONE vibratory grapple and ensuring the quality of the ramming pile, for which the ramming of the ramming pile is carried out by successive penetrations through equal angles in the plan of a number of workings at an angle to the vertical axis of the well and their subsequent wrapping.

FIG. 1 shows the broadening operation; pas figs. 2 shows a concreting operation under a clay solution.

The proposed method is carried out in the following sequence.

First, a well is drilled under a CLAY solution. To maintain the CLAY solution in a mobile state, it is embedded in it. Then, in order to form the broadening in the well at the bottomhole,

2

a device including a cylinder 1 with a bottom shoe 2, provided with a window and an inclined guide 3.

Following the installation of the device, a vibration grab with a intake part 4 of a smaller diameter than the diameter of the well as far as it goes into the inclined guide will be hoisted. When longitudinal vibrations of the vibration grab are switched on, the latter, slipping along the inclined guide, collects and extracts the soil surrounding the well, and thereby creates a local broadening.

After removing the vibrator grab, the guide device is raised,

reversal and subsequent immersion in a new position. In order to be fixed in terms of the guide means, the cylinder has plates 5 which, through the cutting of the borehole wall, prevent the possibility of rotation of the guide means.

By turning the guide: nr 1 device, they create a sound around the entire perimeter. Thus, the broadening of the pile piles

carried out by successive penetrations through equal angles in terms of a number of workings under the ANGLE to the vertical axis of the well followed by their obontirovanie.

For concreting under the clay solution IB, the concrete pipe 6 is lowered, the radial blades 7 are located in the lower part, and the top of the pipe is fastened to the vibrator grab vibrating mechanism. After the pipe is filled with concrete mix 8, concrete is laid. In this case, rotational vibrations are communicated to the tube, which is immersed by the lower vanes with the blades in the newly laid concrete mix, with the help of a vibrator. The radial blades, having made rotational oscillations, interact with the concrete mixture and give it greater mobility. Thus, by increasing the mobility of the concrete mix using iradial blades, it is possible to use more rigid concrete mixes, which increases the load-bearing capacity of the pile and reduces the consumption of cement.

In addition, the rotational vibrations of the vibrator prevent the concrete mixture from getting stuck in the concrete pipe and provide for the laying of concrete without voids. With

concreting with the method of a vertically moving pipe, the clay solution is displaced by concrete from the well into a separate one at the bottom. At the end of the concreting of the beta, the continuous pipe is freed from the mixture and removed to the surface.

Subject invention

A method of raising, for example, a stuffed pile with a vibrating grab by drilling a well and then concreting under a mud solution using a vertically moving pipe method, characterized in that, in order to increase labor productivity by using only one, for example, a vibrating grab and ensuring an increase in the quality of a stuffed pile , the broadening of the ramming pile is carried out by successive penetrations through equal angles in terms of a number of workings at an angle to the vertical axis sk and important, followed by both onirovaniem.
