Definitions
- the present invention relates to a method of projecting a predetermined profile of the cross section of a section of a tunnel to be excavated, together with the draft plan where appropriate, and to a device for executing said method.
- Tunneling works of the tunnel are complex, for example, requiring the realization of a front slope to draw on it the tunnel embossment and, subsequently, the free interior section of the tunnel. These types of jobs are not exempt from presenting deviations from the predetermined profile initially designed on a plane.
- the possible deviations committed are a function, for example, of the physiognomy of the surface where the tunnel truss is located and, consequently, of the difficulty of the personnel, who will excavate the tunnel, of visualizing and locating on the outer surface of the ground the tunnel emboquille.
- An object of one embodiment is to provide a method of continuous and permanent projection of the continuous trace of a cross section or free interior section of a tunnel to be excavated by direct excavation and / or by blasting according to a draft plan. previously defined in order to reduce the costs incurred when an envelope or infra excavation of the inner section is made tunnel free.
- Another aspect of the embodiment is to provide a continuous reference of the geometry of the tunnel cross section regardless of the type of surface on which the projection is made, that is, on the outer surface on which the work is carried out. tunnel embossing or on the surface that represents the excavation advance front of the tunnel itself.
- Yet another aspect of the embodiment is to provide a method of projection to perform staking and definitive location of the tunnel embankment regardless of the type of orography of the exterior surface of the land where the tunnel will be located, allowing personnel to Carry out the tunnel excavation visualize the tunnel embouching and develop the preparatory work of the front slope in a simple way, which avoids the appearance of complex execution problems, in a reduced time and cost.
- the controller module is configured to modify a section Transversal of the standard tunnel depending on the measurements made by the measuring device.
- the controller module comprises an input-output interface of information data.
- Figure 1 shows in a plan view and in elevation a free interior section of an excavating tunnel
- Figure 2 shows in an elevation view the draft plan and the corresponding theoretical section of an excavating tunnel
- Figures 3a and 3b show in perspective an emboquille of a theoretical tunnel between two different surfaces and the same emboquille corrected according to the orography of the exterior surface of the land where the tunnel will be built.
- the projection device 11 shown is adapted to continuously and permanently project on the excavation front of a tunnel both the blasting plan and the free interior cross-section, as well as the tunnel embossments on the exterior surface of the land where the tunnel will be built.
- the measuring device 12 acquires distance data from the physical location of the measuring device itself to the surface where the excavation of the free internal cross-section of the tunnel is carried out, ie excavation front.
- the measuring device 12 is adapted to make topographic maps, 3D maps of the tunnel surface, etc.
- the transmitter-receiver equipment is configured, for example, as a communication module.
- the tunnel excavation advance front refers to both the tunnel truss and the free interior section of the tunnel.
- the modification step of the standard cross-section is performed by the controller module, the modification being a function of the distance data currently acquired by the measuring device 12.
- the controller module is adapted to modify the stored standard cross-section to geometrically compensate for the deviation of distances between different planes existing in the excavation advance front.
- the different distances between planes of the attack front would cause aberrations in the projection of the projected cross section on the excavation advance front.
- a consequence of the opening of the projected laser beam is the generation of an enlarged cross section that would cause an over-excavation of the free interior section of the tunnel.
- the laser projector 13 projects a continuous and permanent laser beam associated with the desired tunnel pattern cross section, where the part of the laser beam of the projected cross section on the transverse plane farthest from the excavation front is corrected by the controller module based on the distance data acquired by a rangefinder, for example.
- the projector device 11 based on the distances acquired is capable of modifying the initially designed tunnel embankment and adapting and projecting an emboquille adapted to the exterior surface of the terrain.
- the controller module calculates the cross-sectional excavation section and the corrected blasting plan associated with each moment of the excavation feed front based on the distance data acquired through the rangefinder and the geographical or physical position of the projection device 11.
- controller module is adapted to supply drill disposal data to the laser 13 projector projecting said positions on the excavation front. Explosive charges are housed in drills made by drilling through a Jumbo in a scenario where tunnel excavation is done by blasting.
- the projection device 11 does not necessarily have to be located in the central axis of the free interior section of the tunnel, being able to be in proximity to a gable, in the key, etc. from the free section of the tunnel. Therefore, the projection device 11 avoids interfering in the development of the tunnel excavation and, consequently, the number of displacements to which the projection device 11 must be subjected is reduced and, in addition, allows the projector laser 13 to emit a beam Continuous and permanent laser of the corrected cross section.
- the laser 13 projector emits a single laser associated with the corrected cross section. It is necessary that the local laser coordinates be associated with the topography coordinates, which are actually the ones that control the excavation. For this, the guidance device cooperates with the rangefinder that supplies distance data to the controller module.
- the projection device 11 When the excavation of the tunnel is carried out by means of explosives, the projection device 11 is protected by a shield that protects the laser set, rangefinder. When images are to be projected, the shielding is automatically removed, otherwise, the laser beam would collide with the shield, making any visualization of the corrected cross-section of the tunnel impossible. The need for protection is given by the violence of the shock wave, and by the projection of rocks as shrapnel.
- the introduction of the necessary data for the visualization of the section to be excavated can be of several forms. The first, manually through a GUI graphical interface included in the controller module. Another way is to use the input-output port through which a file that includes the geometry of the standard cross-section is downloaded and a third way is to use the transmitter-receiver of communications equipment through which it is received from the server projection the cross section pattern.
- the projection device 1 1 comprises a protective housing that acts to protect the projection device 1 1 from dust and water present in the tunnel excavation.
- the housing prevents any damage resulting from environmental factors.
- the projection procedure can be performed by a computer, loadable into an internal memory of a computer with input and output units and, also, with processor units.
- the computer program comprises for this purpose codes configured to execute the steps of the aforementioned process when executed by the computer.
- executable codes can be recorded on a carrier medium readable within a computer.
