摘要:
The present invention relates to a foundation structure vertically installed on the ground, and comprising: an upper support layer 10 formed on the ground in the vertical direction; and a lower support layer 20 formed so as to extend downward from the upper support layer 10 and such that the width thereof is less than that of the upper support layer 10. The disclosed upper support layer 10 and the lower support layer 20 are structures formed from soil solidified by means of feeding and mixing an earth and soil-solidifying agent therein, and therefore are efficient and prevent overload due to boring equipment.

The invention relates to a method for moulding a part (100), comprising the following steps: placing at least one prestressing device in a first element; placing the first element (20, 60) such that it faces a second element (1); prestressing of the at least one prestressing device; introducing ultra-high performance fibre-reinforced concrete (51) into the receiving space; controlling a progressive modification of one of the elements (20); and demoulding the tubular element (20).
摘要:
A cementation pile comprises a longitudinal through-hole (1) and a plurality of through-holes (2) that extend transversely to the longitudinal hole (1) from the longitudinal through-hole (1) to the outer face of the pile, and can additionally comprise check valves arranged in the transverse holes (2) and designed such that the transverse holes (2) and the check valves allow unidirectional communication between the inside of the pile and the outside of the pile, from the longitudinal through-hole (1) to the lateral outer faces of the pile.

Rammpfahl (1), mit einem im Wesentlichen zylindrischen Schaft (2), wobei der Schaft (2) ein erstes Pfahlende (1a) und ein zweites Pfahlende (1 b) ausbildet, wobei am Rammpfahl (1) im Bereich des zweiten Pfahlendes (1 b) eine Muffe (3) angeordnet ist, wobei die Muffe (3) oder der Rammpfahl (1) im Bereich des zweiten Pfahlendes (1 b) einen Anschlag (9) aufweist, sodass ein weiterer Rammpfahl (1) mit einem ersten Pfahlende (1a) bis zu einer durch den Anschlag (9) definierten maximalen Einstecktiefe (T) einsteckbar ist, wobei die Muffe (3) und/oder der Rammpfahl (1) im Bereich des zweiten Pfahlendes (1 b) im Inneren zumindest einen sich zumindest im Wesentlichen bis zum Anschlag (9) erstreckenden Hinterschnitt (8) ausbildet bzw. ausbilden.
摘要:
Prestressed composite structural elements, such as columns and beams comprise an open hollow member which is defined by enclosing walls which walls have internal and external side means, a first shear stress being applied to the said external side means and a filler material in said elements having an opposing shear pre-stress.
摘要:
A pile casing comprising a hollow that extends through an entire length of the pile casing, wherein the pile casing is manufactured of a first material selected from the group consisting of a polymer material and a composite material comprising a polymer material and at least one of glass fibers, carbon fibers, steel fibers and wood. A pile comprising such a pile casing and a filling that fills the hollow, wherein the filling comprises at least one material selected from the group consisting of sand, gravel, concrete, wood, glass, glass fibers, metal, carbon fibers, steel fibers, basalt fibers, asphalt, asphalt concrete, and a composite comprising at least one material selected from the group consisting of sand, gravel, concrete, wood, glass, glass fibers, metal, carbon fibers, steel fibers, basalt fibers, asphalt and asphalt concrete.
