RU16001U1 - DEVICE FOR ESTABLISHING A PACKED PILES - Google Patents

Abstract

A device for erecting a stuffed pile containing a casing pipe, characterized in that the casing pipe is made with chains fixed around the perimeter of the lower end of the casing pipe, and a pointed metal core is inserted into the inner cavity of the casing pipe.

Description

Stacked pile device

The utility model relates to construction, namely to the construction of pile foundations.

A device for manufacturing a printed pile containing a casing with a lost shoe, a stopper with an annular cavity and a conical cover, a bottom made of filter material, a concrete conduit and a drain pipe equipped with non-return valves is known. (Copyright certificate No. 966156, class E02D 5/38, U02D 7 / 00.1982). The disadvantage of this device is the design complexity.

The closest analogue is a device for erecting a stuffed pile containing a casing with a skinny plug} installed in its cavity, a shoe and a screed drive. (Copyright certificate No. 1224381, RV, class E02D 5/38, 5/42, 1986.). The disadvantage of this device is the presence of a filter plug, a lost shoe and spring-loaded clamps.

The technical result of the proposed utility model is to simplify the design of the pile device without reducing the strength and bearing capacity of the printed pile.

The problem is solved due to the fact that the casing is complete with chains fixed along the perimeter of the lower end of the casing and

E02D 5/38, 5/42

A pointed metal core is inserted into the inner cavity of the casing.

A causal relationship between the totality of the essential features of the claimed utility model and the achieved result is as follows. The use of fixed chains around the perimeter of the lower end of the casing allows you to create a gap between the casing and the wall of the well, which facilitates the extraction of the casing from the well. The use of a pointed metal core eliminates the filter plug, the lost shoe and spring-loaded clips from the known device, which simplifies the design of the pile device without reducing the strength and bearing capacity of the stuffed pile.

Pa fig. I shows a device at the time of well formation; FIG. 2 - device at the time of concreting the well.

The device consists of a casing pipe 1 with chains 2 fixed to the perimeter of the lower end of the casing pipe 1 and a pointed metal core 3 is inserted into the inner cavity of the casing pipe 1. The device works as follows in a scanty way. The casing 1 with chains 2 and with a pointed metal core 3, is immersed in the ground with a hydraulic hammer to the desired elevation to form a compacted well. Then the metal core 3 is removed from the casing 1 and

the casing 1 is installed reinforcing frame 4 for reinforcing piles. The casing pipe 1 is filled with dry concrete mixture 5 with the required amount of water and is removed from the well. In this case, the concrete mix fills the formed well. The gap formed by the chains 2 between the casing 1 and the wall of the well facilitates the removal of the casing 1 from the well. As a result of wetting the dry concrete mixture and its further setting, concrete is compacted and hardened in the well.

The proposed device simplifies the technology of construction of a stuffed pile without reducing strength and layers; it has the ability of a stuffed pile.
