MENETELMA JA LAITE MAAPERAÅN PAKOTETTAVIEN PUTKIEN OHJAAMISEKSIMETHOD AND APPARATUS FOR GUIDING GROUND PIPES
Keksintd kohdistuu maaperaån pakotettavan putkiston ohjausme-netelmåån, jossa putkistoa pakotetaan tasalaatuiseen pehmeåån maahan ja sellaisessa syvvvdesså maan pintaan nåhden, ettå putkiston karjesta on iohdettavissa maata leikkaava varsi maan pinnalle ilmaisemaan putkiston kårjen aseraaa ja varren avulla voidaan maan pinnalta valittaå putken kårjelle sen suuntaa muuttavia voimia.The invention relates to a method of guiding a pipeline forced into the ground, in which the pipeline is forced into a uniform soft ground and at such a depth with respect to the ground surface that the cutting arm of the pipeline
Enneståån tunnetaan tunnelinrakennuksessa tarkkailutapoja, joissa tunnelin alkupaåsta tarkkaillaan valmiin tunnelireiån kautta kårjen etenemissuuntaa ja pyritåån tunnelireiån kautta aikaansaamaan kårjen suunnanmuutos tarvittaessa. Lyhyillå putkistojen pakotusmatkoilla annetaan putkistolle riittåvån tarkka alkusuunta, jolloin putkisto pitåå yleenså suuntansa hyvåksyttåvållå tarkkuudella.In tunnel construction, monitoring methods are already known, in which the direction of travel of the tip is monitored from the beginning of the tunnel through the completed tunnel hole and an attempt is made to change the direction of the tip through the tunnel hole if necessary. In short forcing distances of pipelines, the pipeline is given a sufficiently precise starting direction, in which case the pipeline generally maintains its direction with acceptable accuracy.
Kun putkistoa on pakotettava maaperaån vaakasuunnassa pidem-piå matkoja, kuten yli 50 metriå ilman vålikaivantoja ja maa-perå on pehmeåå maata tai suota, ei nykyisin tunnetut mene-telmåt sovi pidempiin putkilinjoihin. Jos putkiston kårkeen sijoitetaan ohjauslaitteet jotka kååntåvåt kårkeå tarvittaessa, tulee kårjen paino niin suureksi, ettå se alkaa painua vetisesså suomaassa alaspåin huolimatta ohjauksesta. Ohjaus-kaan ei onnistu suonkaltaisessa maaperåsså, koska putkisto ei saa ohjauksen kannalta vålttåmåtontå tukea ympåroivåstå maa-peråstå. Tarkalla alkusuuntauksella voidaan edetå suomaassa j noin 50 metriå, jos putkiston paino on onnistuttu saamaan sellaiseksi, ettå noste ei pyri nostamaan sitå ylfis eikå sen oma paino pyri painamaan sitå alaspåin.When the pipeline has to be forced over longer distances in the horizontal direction of the ground, such as more than 50 meters without intermediate trenches and the ground is soft ground or swamp, currently known methods are not suitable for longer pipelines. If control devices are placed at the tip of the piping that turn the tip when necessary, the weight of the tip will be so high that it will start to sink down in the watery swamp despite the guidance. Steering is also not possible in similar soils, because the pipeline does not receive the necessary support from the surrounding soil for steering. An exact initial trend can be made in Finland and about 50 meters if the weight of the pipeline has been such that the buoyancy does not tend to lift it, nor does its own weight tend to push it down.
Keksinnon mukaisella menetelmållå ja laitteella saavutetaan ratkaiseva parannus edellå esitetyisså epåkohdissa ja keksin-n611e on tunnusmerkillistå se, mitå on esitetty patenttivaa-timuksissa.The method and device according to the invention achieve a decisive improvement in the above-mentioned drawbacks, and the invention-n611e is characterized by what is stated in the claims.

Keksinnon tårkeimpinå etuina voidaan pitåå, ettå putkiston kårjen asema sen edetesså on koko ajan nåhtåvisså, kårkeen on johdettavissa hallitusti sitå suuntaavia voimia ja maan pin-taan ulottuva varsi voidaan tilapåisesti irrottaa, jos varren kohdalle osuu esteitå.The most important advantages of the invention are that the position of the tip of the piping as it progresses is always visible, forces guiding it in a controlled manner can be applied to the tip, and the arm extending to the ground can be temporarily removed if obstacles occur at the arm.
Seuraavassa keksintoå selitetåån låhemmin viittaamalla pii-rustukseen, jossaIn the following, the invention will be explained in more detail with reference to the drawing, in which
Kuvio 1 esittåå varsiohjattua putkiston pakotusta maaperåån. Kuvio 2 esittåå koneiden kåyttoå ohjauksessa.Figure 1 shows the arm-guided forcing of the piping into the soil. Figure 2 shows the use of machines in control.
Kuvio 3 esittåå eråstå varren poikkileikkausta.Figure 3 shows a cross-section of an arm.
Kuviossa 1 pakotetaan peråkkåin toisiinsa hitsattuja putkia 5 maaperåån aloituskaivannosta låhtien (ei nåytetty) tunnetun voimalaitteen kuten hydraulisylinterin avulla. Etummainen putki on varustettu kårkikartiolla 4, jolloin putki syrjåyt-tåå sivulle maa-ainekset. Maaperån pitåå olla pehmeåtå, mår-kåå savea tai suonkaltaista, jotta syrjåytys onnistuu. Kårki-osan 4 edesså on toinen kartio 2, johon on kiinnitetty maan pintaan ulottuva veitsiosa 1. Koska maaperån on oltava pehmeåtå pystyy veitsiosa leikkaamaan itselleen kapean railon putken ylåpuoliseen maaperåån. Kåytånnosså putken pakotussy-vyys voi ulottua arviolta noin 2 metriin asti. Veitsiosan 1 ylåpååsså on kiinnitysosia 3, joista veistå voidaan nostaa, painaa tai kiertåå erilaisten ohjaustoimintojen aikaansaami-seksi. Myos veitsi voidaan vålillå nostaa ylos ja myohemmin painaa koneellisesti alas, jolloin kartio-osat liittyvåt toisiinsa. Veitsen kiertåminen aiheuttaa sivusuuntamuutoksen kårkiosalle, sillå levymåinen veitsiosuus toimii peråsimen tavoin maaperåsså liikkuessaan.In Fig. 1, pipes 5 welded to one another are forced one after the other from the starting pit of the soil by means of a known power device (not shown) such as a hydraulic cylinder. The front pipe is provided with a tip cone 4, whereby the pipe displaces the soil materials to the side. The soil must be soft, wet or clay-like for successful displacement. In front of the tip part 4 there is a second cone 2 to which a knife part 1 extending to the ground surface is attached. Since the soil must be soft, the knife part is able to cut itself into the soil above the narrow groove pipe. In practice, the forcing depth of the pipe can be estimated to be up to about 2 meters. At the top of the knife part 1 there are fastening parts 3 from which the knife can be lifted, pressed or rotated in order to provide various control functions. The knife can also be raised from time to time and later pressed down mechanically, whereby the cone parts are connected to each other. Rotating the knife causes a lateral change in the tip part, as the plate-like knife part acts like a rudder when moving in the soil.
Kuviossa 2 on esitetty tyokoneen 9 avulla suoritettava ohjaus veitsivarren 6 vålityksellå. Varsi 6 on kiinnitetty kauhaan osasta 3, jolloin tyokoneen avulla saadaan varteen pystysuun-tainen liike ja pieni tarvittava kiertoliike. Varren 6 ylå-pååhån on asennettu polttomoottorikåyttoinen tårytin 8, jolla : voidaan huomattavasti parantaa veitsen sekå kårjen etenemis- tå. Varsi 6 on alapååståån kiinnitetty tåsså tapauksessa ket-Figure 2 shows the control performed by means of the working machine 9 via the knife arm 6. The arm 6 is attached to the bucket from the part 3, whereby a vertical movement of the arm and a small required rotational movement is obtained by means of a working machine. An internal combustion engine driven grater 8 is mounted at the top of the arm 6, with which: the propagation of the knife and the tip can be considerably improved. The arm 6 is attached at its lower end in this case to the chain.

Tåsså ta-pauksessa tyokoneen avulla voidaan ainakin varren etenemistå auttaa tyontåmållå sitå eteenpåin.92507 3 by means of jun 7 from the arm holder 10 to the tip part 4. In this case, at least the advancement of the arm can be aided by pushing it forward with the aid of the machine.
Kuviossa 3 on poikki le ikkaus varresta 1, jolloin sen veitsi-måinen muoto tulee esille. Varren pitåå olla ohut, mutta sen on kuitenkin kestettåvå voimat, jotka se vålittåå kårkiosaan. Myos muunlaisetkin profiilit tulevat kysymykseen, joilla on etureuna teråvå. Profiili voi olla myos ontto, jolloin sen kautta voidaan vetåå kårjelle joissain tilanteissa tarvitta-via asioita, kuten såhkojohtimia, paineputkistoja tai paine-vettå pienentåmåån kitkaa, jos maaperå on liian kuiva. Paine-putkiston avulla voidaan esim. kårkikartion 4 eteen jårjeståå hydraulisesti pyoritettåvå kartioruuvi, joka murskaa syrjåy-tettåvån maaperån helpottaen etenemistå.Figure 3 is a cross-sectional view of the arm 1, showing its knife-like shape. The shaft must be thin, but it must be able to withstand the forces it transmits to the tip. Other types of profiles with a leading edge are also relevant. The profile can also be hollow, so that things needed in some situations, such as electrical conductors, pressure pipes or pressure-water, can be pulled to the top to reduce friction if the soil is too dry. By means of the pressure piping, a hydraulically rotatable cone screw can be arranged, for example, in front of the tip cone 4, which crushes the soil to be displaced, facilitating the progress.
