Abstract

This invention relates to a machine and system for constructing closed trench tunnels without holding up traffic, which comprises a pre-fabricated steel arched bridge structure over which the vehicles travel. A roadheader machine or mining cutter head, or any other system, is suspended from the structure, and excavates the area to be constructed, while a collecting shovel, also suspended from the structure, removes the earth excavated by the roadheader and deposits it in armoured vehicles towed by trucks that are inside the tunnel already constructed. Once a certain area has been excavated, pre-fabricated concrete segments, that will give the closed trench tunnel its shape, are installed or assembled, with a combination of three different types of segments (side, floor and roof), which are transported on low beds or slabs towed by trucks that pass through the tunnel. Said segments are hooked and lifted by a crane installed suspended from the structure of the bridge. Once the segments have been assembled and secured using bolts or any other method, forming a new stretch or section, the machine (bridge) advances to a new stretch using wheels that raise it and rotate it in any direction hydraulically and place it in the required location to construct the new stretch or section.

Claims

MODIFIED CLAIMS received by the International Office on July 10, 2012 (07/10/2012).

1. Machine for the construction of closed trench tunnels without stopping vehicle traffic, characterized by being composed of a structure in the form of an arch bridge (20) designed to allow the passage of vehicles over it, by which it is possible to work in the construction of the tunnel at the same time that the vehicles follow their normal traffic and constitutes the main characteristic and advantages of this invention.

2. Machine for the construction of closed trench tunnels without stopping vehicle traffic according to claim 1 characterized in that the structure (20) of the machine is designed in prefabricated sections that can vary in their shapes, sizes, materials and capacity according to the need and that facilitate their assembly or disassembly in any place where its operation is required.

3. Machine for the construction of closed trench tunnels without stopping vehicle traffic according to claim 1, characterized in that it has rails (3) in the lower part of the structure (20) which allow a head to hang and move from there cutting or shearing machine (1) mining type or any other available technique that allows the excavation of any material that presents the land a shovel collecting which is in charge of collecting and depositing in the tanks (4) the excavated material and that can vary in its shape or size as needed, a bridge type crane (5) which allows them to move and can lift and place the prefabricated segments (12,14,15) in their assembly place.

4. Machine for the construction of closed trench tunnels without stopping vehicle traffic according to claim 1, characterized by having a system of hydraulic wheels (17) located in the two support points of the structure (20) that allow it to lift it and move in any direction until your next section or section to be built.

5. Machine for the construction of closed trench tunnels without stopping the traffic of vehicles according to claim that is characterized by having a main motor that uses hydraulic power and distributes it to give mobility and operation to the different components of the machine.

6. Machine for the construction of closed trench tunnels without stopping the traffic of vehicles according to the claim that is characterized by using a design of prefabricated segments {12,14,15) that allow it to be transported by its size and shape within the same tunnel already built by means of slabs or low beds (16) pulled by a vehicle or tractor.

7. Machine for the construction of closed trench tunnels without stopping the vehicle traffic according to claim 6 because it is characterized to use prefabricated concrete and steel segments that thanks to the prefabrication are very fast for its manufacture, transportation, assembly and which can be pre-designed by previous studies according to the direction of the tunnel.

8. Procedure for the construction of closed trench tunnels without stopping vehicular traffic is characterized by construction stages that determine a cycle in a certain time and which consists of a first stage of construction that consists of demarcating the area next to excavate with a paving cutting machine (9) which allows a cleaner cutting that can not be done by the cutting head (l) second stage of construction that consists of lifting and advancing the machine to its location by means of its hydraulic wheels (17) which can be operated by a computerized system, manual or any other available technique. third stage of construction that consists of using the cutting head or scraper (l) to excavate the area and can be operated by a computerized system, manual or any other Available technique. Fourth stage of construction consisting of using the shovel picker (2) or any other technique such as mini vehicles excavators and deposit and extract the material excavated in tanks (4) that transited inside the tunnel. fifth stage of construction that consists of conditioning the excavated area using planers, compactors (10) or any other available technique as well as the application of some sealant (11) or slurry in the area that can improve the conditions of assembly and construction of the tunnel. sixth stage of construction that involves transporting inside the tunnel the prefabricated lateral or wall segments (12) in plates or low beds (16) to the excavated area where the bridge type crane (5) hooks them, lifts and places them in position where it is secured to the previous one using bolts (13) and any other available technique, 3 wall voussoirs (12) are installed on each side in total 6. seventh stage of construction consists of transporting inside the tunnel the prefabricated floor segments (14) in plates or low beds (16) to the excavated area where the bridge type crane (5) hooks them, lifts them and places them in position where it is secured to the previous one using bolts (13) or any other technique available, 2 floor segments are installed in total. eighth stage of construction that consists of transporting inside the tunnel the prefabricated roof segments (15) in plates or low beds (16) up to the area excavated where the bridge type crane (5) hooks them, lifts and places them in position where it is secured to the previous one using bolts (13) or any other available technique, 2 roof segments are installed in total and thus completing a whole new section or section with a total of 10 prefabricated segments and which can be sealed or secured by any other available technique such as the injection of concrete or cement slurry.
