Formed by a base (2) in a "U" cross section with a bottom (4) and side walls (5), finishing at one end in a larger spherical sector of the base (12) and at the other in a smaller spherical sector of the base (13), and a cover (3) with a curved cross section finishing at one end in a larger spherical sector of the cover (17) and at the other in a smaller spherical sector of the cover (18). Once the cover (3) and the base (2) are joined, the larger spherical sectors (12) (17) complement one another to form a larger spherical surface, and the smaller spherical sectors (13 (18) complement one another to form a smaller spherical surface designed to remain within the interior of the larger spherical surface thereby forming a hinge joint. Figures 6 and 11.
摘要:
The invention is essentially focused upon the development of elements made of a flexible material which will cover the cutting edges of the rails (2) and of the posts or vertical sections (1) which support the rails of the metallic guard-rails found in roads. They consist of a protective element for the cutting edges of the rails (2), an upper protective cap (8) which fits at the head over the upper side of the section (1) which protrudes from the rail, and lower lateral protective elements which embrace the front or rear sides of the section where it protrudes from the rail, or which independently attach to each of its flanges.

Based on the system of the invention, provisional road sign barriers and even permanent medians can be formed based on the correlative, interconnectable arrangement of a number of equal modules, some male and others female, for connecting, which are made of adequate plastic, are hollow and equipped to enclose an electrical supply and corresponding internal lamps that will provide a correct view and real volume of the formed barrier. The modules include, in addition to a metallic reinforcement structure, some sheets that act as elements which absorb the impact of vehicles. The modules will be filled with bags of water, or with sand and/or concrete, as weights, to form a static barrier that carries out the function of signposting and beaconing for works on highways and similar places, and of protecting against the impact of vehicles.

The invention relates to an underground pipe and cable gallery which can be inspected. The inventive gallery comprises two vertical, opposing trays (1). One of the aforementioned trays (1) is equipped with support trays (2) which are intended to support cables and pipes, while the other tray comprises supports (26) which are used to support numerous flip covers (15). Said flip covers are articulated to the support trays (2) and can occupy two positions, namely: a first essentially vertical position in which the cover is connected to the two adjacent support trays in order to form an independent compartment and a second essentially horizontal position whereby the cover is resting on the supports (26), such that the compartment thus created can be accessed from the outside.

The invention relates to an articulated conduit that is used to house underground pipes. The inventive device comprises a U-shaped base (2) having a bottom part (12) and lateral walls (5). One end of said base comprises a larger spherical base section (12) while the other end thereof comprises a smaller spherical base section (12). Moreover, said device comprises a curved cover (3) comprising, at one end thereof, a larger spherical cover section (17) and, at the other end of same, a smaller spherical cover section (18). Once the cover (3) and the base (2) have been connected, the larger spherical sections (12, 17) join together to form a larger spherical surface and the smaller spherical sections (13, 18) join together to form a smaller spherical surface which is designed to remain inside the larger spherical surface, so as to form a ball-and-socket joint.

It comprises two opposite, vertical trays (1), whereof one is equipped with pallets (2) used to hold cables or conduits whilst the other has supports (26) whereon a plurality of hinged lids (15) can rest. The latter are connected to the pallets (2) and can have two positions; an appreciably vertical one to form an independent compartment joined to the two adjacent pallets, and the other position is appreciably horizontal and resting on the supports (26), so that the compartment thus defined is accessible from the outside.

Modular chest for underground mains made up of various identical panels (2) coupled amongst each other with overlapping. Each panel (2) has on one of its borders, a plurality of hooks (4) capable of introducing themselves into the corresponding lodges (6) placed on the front side of another panel (2) previously assembled. Once the panels are flushed at the same height, the combination cannot be decoupled by simple traction. Figures 2 and 4.
摘要:
Procedure for making in-situ underground manholes intended for the passage of electric and telephone ducts which are dimensioned so as to permit the operator's work inside for carrying out repairs, mounting, maintenance, etc. of electric and/or telephone networks. The procedure is based on obtaining a module made of a tough, nonconducting rustproof light-weight material which is laid in the corresponding hole on the ground and then it is externally filled up with concrete to complete the manhole construction. The inner mould or module is made by joining together two identical square cross-section pieces (1) with a longitudinal profile which will determine the manhole opening in this joining together of both pieces.
