Description

The invention relates to a construction vehicle (ground tracer) for laying pipes, mini-pipes, cables and installations in asphalt roads, but also in any other soil condition, at a depth of for example 100 cm. The mini tubes etc. are laid quickly and comfortably in one go. In these mini tubes then, for example, optical fibers or copper / coaxial cables or other applications for transporting various media, whether liquid or solid form, built to move so quickly, for example, communication lines to build a state-of-the-art fiber optic telecommunications network can. This can be used, for example, to lay cable TV and communication lines for telephony, video and broadband Internet.

In the current market, there are some individual components that make up the ground tracer, such as pumps, suction devices, and prime movers, but which are only suitable for cutting the asphalt. Other components such as the tractor, such as a tractor, must be particularly powerful, because high hydraulic power is needed. For the introduction of the pipes and various installations, a unique tracer sword is needed, which, as a result of the built-in cameras, enables fully automatic laying, monitoring and thus reproducibility of the installation process. Furthermore, as a result of the built-in nozzles backfilling and immediate stabilization of the processing piece of road including all security measures are possible.

According to the current state of the art, however, there is no construction equipment that makes Künetten for the laying of pipes in a depth of up to 100 cm, then laid at the same time mini pipes and in a work train the jail again filled to make the road immediately accessible again. In the conventional production of a cable bezel, ie removing the asphalt surface, separating the soil, exposing the internals, laying the pipes and cables, Einsanden the laid pipes and cables, insertion of a warning tape, refilling and compression of the soil or the new road installation and finally until new asphalting, often pass to 12 months.

All this saves you from the groundtracer. You can lay state-of-the-art technology such as fiber optic cables as well as all other media that can be transported through pipes in minutes. The groundtracer travels through a street in one, laying all the pipes in one go for a total length of 2 km, for example. The advantageous effect of the invention is that almost no disruption of the traffic or the environment a laying of mini tubes or fiber optic cables, as well as all other lines, which can be introduced simultaneously in high numbers, a weeks-long construction site and blocking roads no longer required power. Cable installations with a maximum dimension of 50 mm can thus be installed quickly and with high construction cost savings. In particular, however, the time is crucial, as even with strong installations an extremely fast installation of up to 200 m and more per hour is possible. The main area of application of the Ground Tracers is the urban area and all public and private roads as well as on highways and highways, where a conventional installation due to traffic is almost impossible. A significant advantage also results from the installation detection, which takes place in the same operation. In this case, the charts read into the system are checked and compared by means of millimeter GPS and, on the other hand, visually recorded in fixtures that are not present in plans and reproduced by means of data carriers on request to the road keeper. In the course of the installation, the recording of all parameters such as low-frequency and high-frequeny cable finder, microwave transmitter, X-ray / radar transmitter, cameras, and so on. Main overview Wide-angle main vehicle in the direction of laying direction, Second Main camera wide angle 180 °, rear installation vehicle, cameras in tracer sword incl. Strong LED illumination for recording damaged installations and laying of cables and pipes in the lowest layer. The second camera to refill the Künette and another camera to complete the Künette. Furthermore, the operating conditions of the ground tracer, the propulsion speed, the depth of cut, the temperature of the soil and the outside temperature, the moisture content of the ground and the outside are recorded. Location and time using GPS data, cutting angle of the saw blade, compass, and other parameters on working pressure of hydraulic systems, etc.

In Fig. 1, 2 and 3 the construction vehicle according to the invention, the ground tracer is shown. The following numbers without indication of Fig. Refer to these. The components are all numbered the same.

At the beginning of the operation, as before the start of cut, the rotary cutting disc 1 together with built-in value 4 is pressed into the ground via the adjusting motor with hydraulic arm 8. The asphalt is cut with the cutting wheel 1. The ground tracer begins to drive, with the tracer sword 4 raised for the time being, the cutting disc 1 is introduced into the medium via the hydraulic arm 8 and, after reaching the standard installation depth, the tracer blade 4 is likewise placed on the standard laying depth to be laid. About the hydraulic arm 8 is the leadership of the tracer sword 4 and thus the best installation on the controlled at the lowest point of the jury. The divisor 1 digs into the ground until the standard laying depth of up to 100 cm is reached. The cutting disc 1 or the tracer disc cuts the asphalt, stone, concrete, etc. and pushes as fine granules aside or conveys them upwards. For a suction device 15 is provided. The blade 1 is irradiated with water from the water tank 11. The water is forward fed from the water tank 11 in hoses on the tractor 14 to the water pump 3 and fed to the water injection 2. The high-pressure pump 3 irradiates with the water, the tracer disc 1, which is fed through the nozzles of the inside of the tracer housing 12, and removes the dirt, soil or the micro-granules from the tracer disc 1. Immediately to the tracer disc. 1 the built-in value 4 is connected, which by a Vorlaufschwert, which is attached directly to the tracer disc 1, and also includes spray nozzles for cleaning the tracer disc 1, the fine slot, the trench or the fine chine in the asphalt, for example 20 holds up to 50 mm open. Due to the built-in value 4 various micro tubes from 5 to 50 mm are laid, which are introduced from the drum 5 via the tractor via rollers 6 by the built-in value 4 in the chine.

The mini tubes are on drums 5 ( Fig. 1 ) in the desired package size, that is summarized in each case 2, 3, 4 ... and more pipes or cables, which are desired for installation and in the built-in value 4 ( Fig. 1 ) and laid in the ground. In addition, the built-in value 4 ( Fig. 1 ) in area 7 ( Fig. 6 ) inserted a so-called cable warning tape above the laid pipes.

The built-in value 4 with its cutting disc 1 can be moved vertically with the lifting and pivoting device 7 in height. In Fig. 2 you can see that the swivel device can also be moved horizontally. In Fig. 1 a turntable 9 is installed, so you can tilt and rotate the built-in value 4 together with blade 1 also laterally. Thus, an oblique installation, for example, under a sidewalk, but also the economic use of an existing cable bezel allows so in addition to other lines and optimal utilization of the road surface, a transfer is made possible.

In asphalt roads, but also in any other soil condition, pipes or other installations are laid in one go. At the same time during installation, the rinsed-in road installation material and soil from correspondingly dimensioned suction devices 15 is sucked to the left and right of the mounting blade 4 and fed to a large container. At the same time, the processed and possibly filtered material is removed again from the large container at the bottom and fed back to the ground via a pump 3, then via the built-in blade 4. The pump 3 is two pumps 1 ( Fig. 2 ), one acts as a water pump, the other is used to suck the dirt and the soil. Should it be desired by the road owner, the material removed is not fed back, but it is instead injected via the built-in value 4, a two-component mixture from the designated two-component tank 10 into the soil, which thus the wishes of the road keeper from soft to rock hard in the curing stage serves to stabilize the road again. Also, the introduction of various granules and other materials are possible with and without pressure. Immediately above the rails of the pivoting device 7 (FIG. Fig. 1 ) is this two-component tanks 10. The water tank 11 ( Fig. 1 ) is filled at the beginning of excavation to 2/3 and the water is removed by the pump 3 at the top of the tank 11 and fed to the tracer housing 12 at high pressure.

Fig. 6 shows the tracer sword on average. To control the laying are in the tracer sword up to four cameras 1, 3, 5 and 8 (in each case Fig. 6 ) built-in. Each camera is equipped with LED lighting, giving a continuous view and good lighting. The digital camera 1 in the lowest area records the trench bottom and the outlet of the lowest tubes 2, the so-called backbone tubes. Above this is the second camera 3. Above this second camera 3 the branch pipes 4 (10x10mm) are laid and up to 30 or more pipes can be installed at the same time. Above it is the camera 5, which accommodates the laying of the branch pipes 4 and the filling of the overlying area 6 for filling material. With these recordings, the installation can be optimally controlled and logged. The area 6 is used to refill the chisels, these can be re-filled both with the previously removed and sucked, thus dismantled, material, as well as with a so-called two-component material, which is injected or introduced directly into the area 6 in the soil, so that the chemical reaction of the two-component material can take place. The reaction can range from foaming to backfilling against all other chemical conditions. Above the backfill area 6 is the pavement restoration opening 7, from which the surface covering desired by the road renter is introduced into the asphalt or surface. Possibilities of introduction exist for concrete, fine asphalt, liquid asphalt, bitumen, hot or cold bitumen and various other filling materials, which serve for paving fixation. The camera 8 films the final state of the filled and finished road and shows the finished surface. All cameras of the Fig. 6 be in the driver's housing of the tractor 14 ( Fig. 1 ) are displayed by monitor and digitally recorded. The digital record also includes millimeter GPS data, time, date, information about propulsion speed, burial depth, moisture and soil consistency, as well as other relevant and interesting information for the maintainer. For this purpose, on the roof of the tractor 14 ( Fig. 1 ) a GPS antenna 13 ( Fig. 1 ) appropriate. Also mounted on the roof are two wide-angle cameras with a viewing angle of 180 °. The one to show the live performance, on the other hand, the events before and on the other to show the environment behind the device.

The millimeter GPS antenna 13 ( Fig. 1 ) supplies the on-board computer with exact position data so as to adjust the plan data read into the on-board computer and to correct if necessary. The on-board computer forms a unit with the groundtracer and controls the device fully automatically. The imported plan data, if available, is used as a basis to determine existing installations. About the built-in probe system 16 ( Fig. 3 ) below the groundtracer, active lines in the high and low frequency range are measured and their depth and functionality are determined.

In Fig. 3 is the bottom or basic detector 16 to see, which is equipped with various sensors for obtaining additional data, as it Fig. 5 shows. This is the second level of data collection. It is a microwave transmitter 1 ( Fig. 5 ) with a microwave detector 2 ( Fig. 5 ), which are active and passive antenna elements. Next, the microwave sensors 3 ( Fig. 5) and 4 (Fig. 5 ), optionally one of the transmitters 3 ( Fig. 5 ) and the other of the receivers 4 ( Fig. 5 ) is to produce a 3D image of the substrate and to detect internals and various materials in sewer and water pipes. The X-ray / radar end-5 ( Fig. 5 ) and receiving equipment 6 ( Fig. 5 ), which also serve to fluoroscopy of the substrate, another security measure regarding the internals. All detected installations are recorded and their position in terms of height and depth, as well as in conjunction with the millimeter GPS 13 ( Fig. 1 ) saved. This data is essentially also used for the fully automatic control of the groundtracer, which can automatically control an installation depth of a maximum of 100 cm. In other words, if the laying depth is not specified as possible or already used, the fully automatic control of the groundtracer changes the laying depth from, for example, 100 cm to 70 cm or to the specified maximum or minimum depth Minimum installation depth. The laying depth can be limited by the system and an alarm or a stop of the installation will be triggered when exceeding and falling below.

The laying speed is controlled by pressure sensors, which are located on the drive motor 17 (FIG. Fig. 3 ) is located on the tracer disc 1. On the other hand, it is also measured on sensors which are directly connected to the coupling device, the resistance, the perspective of the manpower, measured so as to take the pre-drive speed, up to which limit values are set fully automatically. Other sensors are located on the tracer housing 12 and on the tracer wheel 1, which detect a possible impact or approximately live lines to cause an immediate change in cutting height of the Groundtracers. In other words, even before a live line is severed, the groundtracer stops.

The board computer records in addition to the data of the millimeter GPS 13, data of the sensors in Fig. 5 , also all camera data in Fig. 6 of built-in value 1. In addition, three additional cameras for the environment or working area of the device and all operating states are installed and recorded synchronously and stored on a digital data carrier.
