(54) DEVICE FOR RECONSTRUCTION OF THE MOBILE QUAY ON A WEAK BASE

(57) The invention relates to the field of hydraulic engineering. The purpose of the invention is to increase work efficiency. The device is mounted on a platform 1 moved on crane rails and includes a drill; a new mast 6, a casing with a cylindrical tip and a piston in the lower part by the upward movement mechanism 9 (L

from: 4

In this part, a hollow rod with a working body, a pressure plate with a flat filter and a contour seal, which is mated with the casing can be rotated in a vertical plane, means for preparing and feeding fixing solution to the ground. After the completion of the process of manufacturing the cement-cement pile, the entire sliding part of the device is opened from the soil by mechanism 9. Mast 6 is tilted to a position corresponding to the position of the axis of the adjacent pile of a given fan row of piles, and the process is repeated 3 nl.

The invention relates to hydraulic engineering construction, in particular, to devices for reconstructing port mooring facilities, and can be used in sea and river ports for reconstructing quay berths, which is mainly performed while simultaneously deepening the water area.

The purpose of the invention is to increase the efficiency of work.

FIG. 1 device is shown in the working position; in fig. 2 - detail of the lower part of the device in vertical section; in fig. 3 - casing, cross section;

The device is mounted on the platform 1, which has the undercarriage 2 installed on the crane tracks 3. On the platform 1, there are means for preparing and feeding a fixing solution into the ground, including a mortar mixer 4 and a mortar pump 5.

On the console 1 protruding towards the water area, the platform 1 is mounted with the possibility of tilting the mast 6. In addition, winches and auxiliary mechanisms (not shown) are installed on the platform.

The guide casing 7 is made in the form of a pipe passed through the yoke 8, for example, of a rectangular cross section, adjacent by a wide face to the front surface of the mast 6 (Fig. 3, Fig. DC). In the upper part of the casing 7 there is a mechanism for its movement 9.

The lower part of the casing 7 is provided with a cylindrical tip 10 with a horizontal generatrix. Inside the casing 7 is placed a pistol 11 connected by rods 12 (FIG. 3) with an independent clamping mechanism and a lifting mechanism 13. The floor of the rod 14 is passed through a hole in the center of the piston 11,

At the lower end of the rod 14 is the working body 15.

The upper end of the rod 14 is connected to the rotator 16, and the cavity of the rod through the swivel 17 and the flexible pressure pipe 18 with the mortar pump 5. The plate 19 can be rotated relative to the cylindrical tip 10 and provided with a flat filter 20 and a contour seal 21. The flat filter 20 is connected with a flexible vacuum hose 22 with a vacuum pump located on platform 1 (not shown).

The device works as follows.

After the calculated deepening of the water area (Fig. 1), the device is installed on the crane paths of the reconstructed embankment. The mast 6 is brought into position corresponding to the axis of the cement-cement pile nearest to the front wall of the quay 23. Plate

19 is let into the bottom of the water area and after the start of vacuuming the soil through the filter 20 and the vacuum hose 22, the working body 15 is immersed in the ground with its simultaneous rotation using a 16o rotator. After the calculated depth of the working body 15, it stops pumping into the ground fixing ( for example, cement mortar): with a solution of a mortar pump 5 through a pressure pipe 18, a swivel 17, a hollow rod 14 and a working body 15. A cement cement 24 is formed in the soil with a gradual deepening of the working body 15 with simultaneous mennym its rotation. In case of poorly bearing soils with a fixed solution, additional loads of the working body 15 are made without feeding the fixing solution into the ground.

Soil vacuuming through the filter

20 provides a formable seal

piles and surrounding soil and removal of excess water, and mechanisms 9 and 13 - additional mechanical consolidation of the pile and soil, mainly after the completion of pile formation, and drawing the working body into the casing 7 close to the piston 11, as well as fixing the design level of the bottom of the water area .The production of soil-cement piles using a drilling technology without a pressure plate and vacuuming of the soil would be accompanied by a decompression of the surrounding soil, a rise in its surface and breaks of the fixing solution into aquatum. Oray in the manufacture of the upper parts of the pile.

After the completion of the process of manufacturing the cement-cement pile, including the mixing of the soil with the fixing solution, the evacuation and mechanical compression of the pile body with the surrounding soil, the vacuum pump has come out. The entire remote part of the device is also turned on (the housing 7 with the piston 11, the plate 19 and the working body 15 on the rod 14 is detached from the ground by the mechanism.9, the mast 6 is tilted to the position corresponding to the position of the axis of the adjacent pile of the pile row and the process repeats The adjacent ground-cement pile of this series is made with a partial serif of the body of the previous pile (Fig. 1), which is ensured by an appropriate limitation of the technological failure time between the production of adjacent piles of rows. In the past, Plastun (Primorsky Krai), the specified technological gap should not exceed 3 days. After completion of the production of all the piles of a given row, the device is moved along the embankment to the design plant between the axes of the rows and the production of piles in the adjacent row begins.

which can be located both close to the previously manufactured row, and with a certain gap.

Production of soil-cement piles under water at different inclinations of their axes to the horizon is provided by the hinge coupling of the plate 19 and the casing 7, which, in turn, is achieved by means of a cylindrical tip 10 with a horizontal shaping and reduced cross-section size; ozhu 7 in the plane of the relative rotation of the casing 7 and 5 of the plate 19,

If, in accordance with the calculation of the front wall of the reconstructed embankment, it is necessary to increase the point of application of the resultant soil stripper, then the upper soil zone 25 between the front wall of the embankment and the ground-cement pile nearest to it is meliorized by injection and inserting rigid spacer elements.
