Abstract

A device for erecting stamped foundations containing a base machine, a guide, an immersion mechanism connected to a holder and a support plate, characterized in that the base plate is rigidly connected to the holder using guide bushings, support springs, adjusting fingers, and to create in the face the rammed foundation of the broadened base of hard material in the lower part of the working body provides the ability to install removable platforms for the device to work as a rammer.

Description

DEVICE FOR THE ESTABLISHMENT OF PRESSED FEDERATION FACILITIES

A useful model for construction and can be used in devices for erecting stamped foundations,

A device for erecting a foundation is known, including a tambouring device in the form of a foundation block attached to the bottom of the surface of a massive element (a.c. USSR J 706496 JB 02 D 27/28),

Closest to the utility model is a device for erecting a foundation, containing a base machine that guides the immersion mechanism connected to the working bodies by a clip and a base plate with a jack (AS USSR K & II530JI A E 02 D 7 / EO)

,

The disadvantages of these devices are high labor costs and the construction of foundations and lack of reliability

The purpose of creating a utility model is to increase the reliability of work, reduce labor costs. With the installation of rammed foundations

This goal is achieved by the fact that in the known device for erecting stamped foundations we provide a basic machine, a guide, an immersion mechanism connected to a holder and a support plate, the base plate is rigidly connected to the holder by means of guide sleeves, - ponds of adjusting fingers, and to create in the face of the rammed foundation of the broadened base of hard material in the lower part of the working body of the pre-injector; the ability to install removable plates

to operate the device in, as a tamper

A device for introducing rammed foundations consists of a basic machine about a guide, a cone-shaped working member I, rigidly connected to a clip 2, a support pin 3 is fixed about a clip 2 with the help of guide bushings 4, support springs 5, for changing the depth of tamping of the foundation pit and guide bushings 4

holes 69 are made in which the adjusting fingers 7 are inserted,

Support plates 8 are installed on the guide sleeves 4, and stiffeners 9 are made on the base plate 3

For fastening, give a clear working body I about the base machine with a bracket 10, the hammer is connected to the working body I by cable grips through the eyelets II on the headgear 12

When executing in the face of the rammed foundation a broadened base of hard material, removable plates are installed in the lower part of the working body I, 13 with latches 14

A device for the construction of rammed foundations works as follows

After delivery to the construction site, the device for erecting the foundations is transferred from the transport position to the working one. For this, the damaging mechanism is mounted on the base machine (copying machine). The principle of operation of the device for erecting rammed foundations is shock-mechanical. Rammed foundations are made by a copier equipped with diesel a hammer with a guide and a conical working body I with a spring mechanism for removing it from the ground

The working body I is mounted on the guide using the bracket 10, and the impact from the diesel hammer is transmitted to the working body I through the headgear 12 When working with a diesel hammer in rdul2X

After repeated impact, the cone-shaped working body I is immersed in the base soil. When the ground surface reaches the support area 3, the support springs 5 begin to compress, and at the moment when the accumulated compression force of the support springs 5 is greater than the friction forces and adhesion of the surface of the working body I on the pit wall, separation occurs working body I from the soil medium.

Due to the operation of the lower base plate 3 located along the perimeter of the rammed foundation pit, decompression, loosening, and ground penetration in the area located in the immediate vicinity of the surface of the foundation pit are excluded

The punching process is accompanied by compaction of the soil about the formation of a compacted zone around the side walls and below the plane of the tip of the working body I, associated with the creation of a new soil structure and a decrease in the values of the porosity coefficient

Correction of the neo-ears of the ability of the rammed foundation is done by changing the depth of the excavation of the excavation pit with fixing the length of the guide bushings 4 relative to the holder 2 with the adjustment fingers 7. It is possible to perform stamped foundations with the same neo-soil ability on the ground

For the device of the broadened base with the aim of increasing the bearing capacity (for example, the face of the rammed foundation pit is filled with hard material in portions). Then, removable shushki 13 are installed to the working body I, they are fixed with clamps 14, and the device must be rammed if necessary

After tamping the pit, the working body I is lifted with a spring mechanism, after which the pit is filled with monolithic concrete with compaction with a deep vibrator or in the face

the prefabricated element is immersed and the device is mixed to the place of manufacture of the next foundation
