(57) Abstract:The invention relates to the field of construction, in particular, to the design of driven piles with a drop-down blades. The invention helps to enhance the body piles, to improve safety, increase operational speed and to reduce the pile. Driven pile includes a barrel attached to it located in recesses formed in the shaft, blades, and a device for opening the blades. The positive effect of the application of the new piles is due to the fact that the barrel it is made monolithic, blades attached to the hinge, are U-shaped in plan form and taper from the end wall toward the location of attachment of the side walls of the blade to the body of the pile. Device for opening the blades is represented in the form of a nozzle with a smooth mating surfaces is spherical, facing the body of the pile, and flat, facing toward the end wall of the blade and rigidly connected with it. Put this device in the spherical groove on the body of the piles in the area in contact with the front wall of each blade, and is triggered by the expansion of mortar powder NRS-1, filling the spherical groove of the camera. T the tion piles in the ground. 5 Il. The invention relates to the field of construction, particularly construction of driven piles with a drop-down blades.Known knock-pile, comprising a barrel attached to it located in formed on the stem niches blades and a device for opening the blades. The blades are made trough-shaped with a curved bottom, and the bottom of each niche is also curved, with each blade attached to the barrel by means of a metal plate is cantilevered from the body of the trunk above the niche, and the other in the corresponding blade. The pile shaft provided with transverse channels, indicating niche with the cavity of the barrel, the device for opening the blades presents a hydraulic system located in the cavity of the trunk, and each blade is spring-loaded. /Cm.

The disadvantage of this pile is a hollow shaft with transverse channels, which significantly affects its strength, in addition, the blade having a thickness in the form, are initially in the bulk of the niches in the body of the pile, which also weaken the structure. The blade turned 90oremains connected with the body piles curved metal plate, Naya very low-tech in manufacturing.Strengthening the body piles and improve safety when driving is achieved by the fact that in the driven pile, comprising a barrel attached to it located in recesses formed in the shaft, blades, and a device for opening the blades, the pile shaft is made of a monolithic, blades attached to the hinge, made U-shaped in plan and having tapering to the location of the hinge mounting the blade shape, with the joints of adjacent mounting height of the trunk of blades located on opposite sides of the axis of the barrel at his sides, opposite the end wall of the respective blades, and camera made in the pile shaft in the areas adjacent to the locations of the end walls of the blades, in which is placed the device for opening the blades, but the camera made in the form of spherical grooves on the entire width of the face of the barrel, and a device for opening the blades in the form placed in the groove of the pipe with a smooth mating spherical surfaces facing the body of the pile, and flat, facing toward the end wall of the blade and rigidly connected with it, and a length corresponding to the distance apart of the side walls of the blade, with each pipe laid rest the Fig. 1. In Fig.3 the blade and the pipe after curing solution NRS-1 /enlarged/. In Fig.4 and Fig.5 tube for covering the holes in the side walls of the blades.Driven pile includes a monolithic barrel 1 with the hinge attached and placed in a formed on the stem 1 and 2 niches U-shaped in plan drop-down blades 3 and device for disclosure of these blades 3. The hinges 4 mounting adjacent the height of the barrel 1 of the blades 3 are located on opposite sides of the longitudinal axis of the shaft 1 at its face opposite the end wall 5 of the corresponding blade 3. The side walls 6 of the blade 3 are tapered from the end wall 5 in the direction to the location of the hinge 4 mounting the blade shape.In the barrel 1 in the zones adjacent to the locations of the end walls 5 of the blade 3, is formed chamber 7 for accommodating devices for disclosure of the blades 3. Device for opening the blades are made in the form of a pipe 8 having a flat surface 9 facing the end wall 5 of the blade, and spherical 10, facing the body of the pile 1, smoothly conjugate to each other, and the length corresponding to the distance apart of the side walls 6 of the blades 3 with its nozzle races/P> The gaps at the ends of the pipes should be minimal to prevent leakage of the solution NRS-1 when pouring it into the pipe 8.In the side walls 6 of each blade 3 against the end face of the socket 8 are threaded hole 11, which is closed by a stopper 12 having the outer side of the socket 13 for the key.In the niches of 2 padded pins 14, one end of which is filled in the body of the pile, and the other fixed on the lower part of the end wall 5 of the blade 3 for its retention against inadvertent disclosure when driving piles into the ground.The operation of the piles is as follows. Before driving piles into the ground turn the tube 12 and through the hole in the inner cavity of the socket 8 pumped creamy mortar mix with water powder NRS-1, created by Vniistrom. Tube twist. Thus obtained solution NRS-1 in all the nozzles 8.The pile is then immersed in the soil to the desired depth of one of the known methods and leave in this state for one day. During this time the drug NRS-1, crystallizing, increases its volume by almost half. Under the action of the current on the inside of the pipe 8 to the pressure he takes a cross-section of a spherical shape and has Dave 14, and the blades 3, turning on the axes of the hinges 4, depart from the plane of the piles.Upon further driving piles blade 3 under the action of the soil will turn to lock the upper part of the end wall 5 of the blade 3 in the body of the pile. Driven pile, comprising a barrel attached to it located in the recesses formed on the shaft, the blades and the device for opening the blades, characterized in that the pile shaft is made of a monolithic, blades attached to the hinge, made U-shaped in plan and having tapering from the end wall in the direction to the location of the hinge mounting the blade shape, with the joints of adjacent mounting height of the trunk of blades located on opposite sides of the axis of the barrel at his sides, opposite the end wall of the respective blades, and cameras made in the pile shaft in the areas adjacent to the locations of the end walls of the blades, in which is placed the device for opening the blades, but the camera made in the form of spherical grooves on the entire width of the face of the barrel, and a device for opening the blades in the form placed in the groove of the pipe with a smooth mating spherical surfaces facing the body of the pile, and apart side walls of the blade, and in each pipe laid a detergent solution LDC-1 Vniistrom.
