Description

SUCTION FOR MAKING PILES IN SOIL

The invention relates to the construction, and in fact, to 5cz: equipment for the manufacture of printed ovay, and can be used in the construction of pile foundations of buildings and structures.

It is known yoTpo.iCTBO for extracting building elements from the ground, mainly casing pipes, including a support frame with a leveling device, a grip and power cylinders To remove a casing, a support frame with a leveling device is installed on the ground, the grip is fixed to the pipe, then installed between nsh.sh power cylinders are included in the work (Avt.sv. te 742533, E 02 D 11/00, BI No. 23-80gOo

To install the specified device requires special mechanisms and requires a lot of time. Periodic rearrangement of the gripper during the extraction of the casing also causes a waste of time. Near the casing under the support frame in the soil, a compaction zone is formed, which increases the friction forces when lifting the pipe. When using pile foundations, the upper layers of the soil often have high compressibility (bulk soils,

peaty., waterlogged and t / a,), which complicates the use of the device.

A device for making piles in the ground is also known, including two hollow longitudinal sections mounted with the possibility of radial movement, between which a rod with a tip and a conductor are placed. On the bar and side surfaces of the sections, wedge-shaped vytyups are made. After the device is immersed to a predetermined depth, the conductor is removed and the rod is drilled with a tip. Due to the interaction of wedge-shaped protrusions, the longitudinal sections are first squeezed to the sides, compacting the soil, and

then shifted to the theater, facilitating the removal of the device from the ground (AiST, Gj3. No. II42598, ji 02 D 11/00, BI No. 8-85.) "

DoZisce niTaiiPH requires a good job, so for this you need to wear soil, running t outside by using B8p2yOS1 obkzim l so that you can dig the soil under the ground. To ensure sufficient strength and instability, the rod and a large transverse pressure. This leads to an IMPROVEMENT of the full ... power of the device and an MALFUNCTION of the volume of the cavities of the longitudinal sowing. When lifting the device, stops will be necessary for additional loading of concrete from them. Narrow clearance by the tip and other in-hole machines makes it difficult to release concrete. The design of the device does not provide for the possibility of compaction of concrete soyoi c.

The closest in design to the proposed solution is a device for implementing the method of performing concrete constructions in the soil, the Method is carried out: development of a excavation in the ground, installation of a housing composed of two longitudinal sections in it, removing the housing with alternately raising and lowering the sections and vibration compaction concrete mix when placing 2; orts of sections at the same height (Avt.s with, and 1236062. MKI I 02 D 7/25, 1986 - prototype).

The location of the hydrocyliids of the MEU with the body and the vibration exciter, as well as the absence of: a node for staining sections with each other does not allow the device to be immersed without first developing a excavation in the ground. Compaction of the concrete mixture is carried out on a single lifting ramp using an exciter after closing the lower end of the housing. The end closure is carried out only in the middle of the interval of mutual movement of the sections, i.e. with their full combination in height. When lifting the longitudinal sections, reactive forces are perceived by the guides of the copra boom.

The claimed kzoreghenie iaprazleao to improve the work and quality of manufactured SBEI.

This is achieved by the fact that B; on the other hand, while making avai in the ground, including a casing of two products: sections .; I open two OH cylinders and open them; I extend the two-part block and fasten it securely; 1 on the sections, the power cylinders are articulated at their ends on the sections, with one cylinder placed horizontally and the other vertically, on the walls, one longitudinal grooves are formed from the sections, and “on the walls of another section there are fingers entering the grooves with some clearance. On each part of the shoe are replaceable pads height

about - 0.5 (-6 -j), where Vg is the stroke of the vertical power piston

cylinder, O - side of the cross section of the housing.

Known casing extraction devices require the creation of a painful ::: wow effort. For this, powerful lifting mechanisms or special devices installed on the soil surface are used. Their use is complicated by the fact that when using pile foundations, soils with high compressibility often lie on the surface. Concrete mixture is also densified by special mechanisms (vibration dampers, rammers, pneumatic systems, etc.). - The authors are not aware of the use of casing, consisting of two longitudinal sections, the alternate reciprocating movement of which is used to extract it from the soil and at the same time layer-by-layer compaction concrete mix. Therefore, the claimed solution. Meets the criterion of inventive step.

The invention is illustrated by a drawing, where in Fig. 1 its general view is shown in Fig. 2 is a longitudinal section, in Fig. 3 - transverse sections, in Fig. 4 and 5 show longitudinal sections of the device with a radial displacement of the sections. Fig. B shows the lower part

F11g. 9 and 10 explain the slave ;; zda crepedenine sections DR5G with DR5 / GOM. In FIG. II and 12 show the design of the shoe and the pads and slat oipotiCTsa when placing the armagra in the body of the pile.

The device contains two closed P-obrvzny longitudinal sections I and 2, nested in each other. Longitudinal grooves 3 are formed on the walls of section 2, and fingers included in the grooves are placed on the walls of section I, and the width of the grooves is slightly larger than the diameter of the fingers. In the upper part of the section there are shelves 5,6, with which a double-acting vertical power cylinder 7 is connected through cylindrical hinges. A horizontal double-acting power cylinder 8 is connected through the cylindrical hinges to the walls of the sections. To increase the rigidity of the structure, the enclosed section I should be reinforced with additional walls E 10. On the outer wall of one of the sections there is a loading window with a b-unker II for supplying concrete sushi. The shoe is made up of:, 1 and two parts 12 and 13, fixedly mounted on the sections. On each of the parts of Bash1U1ak, lining 1 and 15 are placed, allowing you to change the angle of inclination of the lower ends of the sections to the horizon. The removable cover 16 with the protrusion 17 is installed on the upper ends of the sections when their top is divorced in the radial direction (Fig. 1,2,3).

The device operates as follows.

The device is installed on the ground surface. The horizontal power cylinder 8 is included in the work. When the rod is pushed out, the top of sections I and 2 is bent in the radial direction. The sections unfold relative to each other around the fingers until the gap between the parts of the shoe 12 and 13 and the pads 14 and 15 (game 4) closes. After installing the removable cover 16, ycTpo.iCTBO is immersed in the ground with conventional pile driving2 / 1 equipment

They had a vibro-load of 8 m, forming a pyramidal cavity in the ground. At the open (stage I in Fig. B), the removable cover 16 rises and the horizontal power cylinder is again put into operation. When the rod is retracted, the top of the sections is shifted to the center. Due to the fact that the width of the grooves in the assembly unit of the sections with each other is greater than the diameter of the fingers, the sections are deployed around their lower ends, pinched in the ground, and take a mutually parallel position. With further retraction of the rod., The power cylinder 8 sections begin to unfold around the fingers. The lower ends of the sections are moved apart, additionally compacting the surrounding soil and creating a broadening of the cavity, which contributes to an increase in the load-bearing capacity of the pile (stage P on d ..ig, b). When the device is clamped in dense soils, the B of which the widening of the cavity broadening by spreading the sections is difficult, retraction of the rod is stopped after the BO sections are brought into a mutually parallel position. Two to five-fold reversal of the stem movement leads to the formation of a pyramidal or X-cavity in the soil with stable walls and a sharp decrease in the friction forces between the soil and

sections.

After sections I and 2 are brought into a mutually parallel position, a concrete mixture is fed into them through hopper II (stage Щ

The master cylinder 8 is translated into a neutral position, in which free movement of the rod is allowed. Then the vertical power cylinder 7 is turned on. When the rod is pushed out, section I remains in place, resting part of the shoe 12 through the overlay 14- on the ground, and section 2 rises up so that a hole for concrete mix forms between the part of the shoe 12 and the overlay 15 ( stage 1U). When the rod is retracted, section 2 drops down, the hole between the shoe part 12 and the pad 15 closes the concrete mixture under the lower ends of section 2

densified (stage U). Due to the resistance of the concrete mixture, the movement of section 2 down stops and the rise of section I begins. Int.; At the part of the shoe 13 and the lining 1 it opens from the door through which the concrete mix enters the cavity in the ground (stage U1) Repeated reversal of the shaft in the power cylinder 7 leads to the extraction / stroma from and layer-by-layer compaction of concrete in the pile body. In this case, in the lifting aode at any elevation, you can turn on the work of the power cylinder 8 and create additional broadening on the pile shaft.

The lifting of the device is carried out by alternately supporting the sowing onto the concrete mixture from the cavity formed in the ground. Depending on the increase or decrease in the angle of inclination of the lower ends of the sections to the horizon, a corresponding increase or decrease in the concrete mix to the walls of the cavity will occur, which will mean 11, a pile with a different cross section will be formed. To regulate this process, depending on the given bearing capacity of the piles and engineering-geological conditions, the proposed device uses interchangeable pads 14 and 15, placed on the parts of the shoe 12 and 13. The pads can have a different angle of inclination of the lower faces to the horizon (Fig. , 7). The value of this angle does not significantly affect the immersion of the device in the soil, as evidenced by the successful use of the construction of pile bases of the tip.

The speed of extraction of the device from the soil depends on the mutual vertical displacement of the sections to it. The higher the value О, the faster the device will rise. However, the displacement cannot exceed half the piston stroke of the vertical power cylinder. At the same time, the hole must remain with the shoe parts and pads, providing a free exit of the concrete mixture from the cavity of the device.
