Definitions

  • the invention relates to the technical field of foundation piles.
  • H / B where B is the width of the foundation and H the seat depth, there are: the superficial foundations, for which H / B is less than 6, for example for soles and rafts; deep foundations, for which H / B is greater than 6, eg for bars, wells and piles.
  • Dark piles can be made of reinforced concrete, prefabricated, or coffered in progress, or even in steel (H profile with reinforced core or palpieu) and are put in place with discharge of the soil.
  • the drilled piles are made of reinforced concrete cast in place in a borehole. When the cohesion of the ground allows it, drilling is done without protection (simple bored pile). In other cases, a metal tube protects the bore (cased drilled pile) or a drilling mud is injected (pile drilled with mud). The drilling is done by auger or roto percussion.
  • the beaten or drilled piles can be of the high-pressure injected type, an injection system composed of cuffed tubes allowing the injection of a grout into the ground.
  • the invention relates more particularly to micropiles of foundation.
  • micropile technique was developed in 1952 by the company Fondelile under the direction of the Italian engineer Lizzi. These first piles were drilled and sealed to the ground by a mortar. These products were used in Italy under the name of "root pile”.
  • minipiles minipiles
  • micropiles root batteries
  • needle batteries the terminology is not fixed. They are called mikropfahl, verpresspfahle, wurzelphale in German.
  • micropiles of foundation conventionally designate piles of modest cross-section, typically of diameter less than 250 mm, set up with tools of small, light and manageable dimensions, in particular for underpinning.
  • micropiles are conventionally bonded to the structure either by sealing with anti-shrink mortar, in the existing foundations, or by a distribution plate embedded in a reinforced concrete header.
  • Drilled micropiles are quite commonly used for undercuts in a small space, in the case of individual habitats in particular. Micropiles are also used in groups (set of vertical micropiles) or in networks (set of vertical and inclined micropiles) for soil reinforcement.
  • micropiles are illustrated in the documents EP-0954645 or US 4650372 .
  • the aim of the invention is to provide a new device for placing micropiles of foundations.
  • the invention also aims to provide a new method of setting up such micropiles, allowing a compressive stress of these micropiles.
  • the first means comprise a sleeve housing with functional play the upper end portion of the micropile head.
  • This sheath guards the micropile sections during their insertion into the ground. This sheath also facilitates the positioning of the first micropile section relative to the foundation element.
  • the second means comprise a transverse bearing surface against the underside of a foundation element such as a sole or a slab or a construction element such as a wall.
  • this transverse bearing surface may be a solid metal plate.
  • the transverse bearing surface is advantageously a metal frame frame.
  • the second means comprise a longitudinal bearing surface and fixing against a lateral face of a foundation element such as a sole or a sill.
  • the device comprises means for adjusting the position of the longitudinal bearing surface and fixing relative to the console.
  • the adjustment means comprise at least one sliding axis and a stop.
  • the adjustment means comprise two substantially radial axes, a first axis supporting an adjustable position stop, a second axis forming a sliding axis of a support plate and fixing against a lateral face of a foundation element. such as a sole.
  • the adjustment means comprise two non-parallel axes, a first substantially radial axis supporting an adjustable position stop, a second inclined axis forming a sliding axis of a support plate and fixing against a lateral face of a foundation element such as a sole.
  • the first axis comprises a threaded portion on which the stop is mounted adjustable in position.
  • the fourth means comprise at least two male parts such as tie rods which are housed in female parts carried by the console, quick coupling means ensuring the connection between said female parts and the console.
  • the concreting is carried out while maintaining an axial compressive stress on the micropile head.
  • the micropile has a residual stress or a prestress in compression, opposing the vertical forces that a swelling soil could exert on the micropile.
  • the method further comprises concreting the micropile head, after hardening the concreting of the volume housing substantially the entire console.
  • the method further comprises concreting a volume placed above the micropile head, this volume containing reinforcements previously fixed on the masonry supported by the foundation element.
  • Drought and soil rehydration can lead to differential movements of land and damage to buildings.
  • some surface soils vary in volume depending on the weather conditions: withdrawal during drought and then swelling on return from the rains.
  • the susceptibility of soils to shrinkage / swelling can be evaluated on the basis of four parameters: plasticity index, methylene blue value, swelling coefficient, linear shrinkage.
  • clay soil is meant a fine soil, including significant proportions of clay minerals (mainly kaolinite, illite, glauconite, smectites such as montmorillonite and beidellite, and interstratified clay minerals). When clay minerals are associated with calcium, the soil is called clayey limestone, marl, or hard clay.
  • the volume of clay soils varies with the water content, between a shrinkage value and a swelling value.
  • the shrinkage can be 30% and the swelling 50% of the initial volume.
  • Subsidence causes disorders in the structural work: traction or shearing cracks, especially at the angles of the openings (doors and windows). These cracks can reach several centimeters of opening.
  • the base of the building can be modified: spill, rotation.
  • Subsidence also causes disorders in the second work fixed on the shell: malfunctioning doors and windows due to the distortion of the bays, detachment of veneers, plaster, tiles and pavements, rupture of pipes and pipes.
  • contiguous blocks can be placed to extend continuous soles. It is also possible to make insulated wells on longrins, in the work.
  • micropiles makes it possible to accommodate a wide variety of soil types, unlike other repair techniques.
