Description
Przedmiotem wynalazku jest sposób zabezpieczania pionowych scian wykopów waskoprzestrzennych za pomoca obudowy przestawnej lub przesuwnej, wyposazonej w rozpory, oraz urzadzenie do rozpierania scian wykopów w postaci prefabrykowanej skrzyni obudowy wykopu. Wynalazek ten ma zastosowanie przy wykopach w gruntach zachowujacych czasowa statecznosc pionowych scian wykopów.The subject of the invention is a method of securing vertical walls of narrow-space excavations behind by means of an adjustable or sliding casing, equipped with struts, and a device for expanding walls excavations in the form of a prefabricated trench support box. The invention is applicable to excavations in soils that retain the temporal stability of the vertical walls of the excavations.
Dotychczas wykopy waskoprzestrzenne zabezpiecza sie za pomoca desek drewnianych, plyt lub poje¬ dynczych pali, rozpieranych wewnatrz wykopu balami ukladanymi pomiedzy slupkami lub podluznicami, prze¬ noszacymi obciazenie od gruntu na rozpory. Dla zapewnienia potrzebnego docisku deskowania do gruntu, wbija sie kliny pomiedzy rozpore, a pozostale elementy obudowy lub tez zwieksza sie dlugosc rozpory poprzez pokrecenie jej gwintem. Znane sa równiez skrzynie lub kosze opuszczane do wykopu.Until now, narrow-space excavations have been secured with wooden boards, boards or water of liquid piles, braced inside the trench with logs laid between posts or stringers, bearing a load from the ground to the struts. To ensure the necessary pressure of the formwork to the ground, it drives in wedges between the struts and the remaining elements of the casing or the strut length is increased through twisting it with a thread. There are also known crates or baskets lowered into the excavation.
Skrzynia przesuwna do ukladania rur wedlug patentu 69593, polaczona jest z urzadzeniem wykonujacym wykopy np. z gryzarka do kopania rowów, która jest przez to urzadzenie poruszana w kierunku pionowym i poziomym. Sklada sie z dwóch scianek bocznych, scianki przedniej uksztaltowanej przewaznie jako spychacz, ze scianki tylnej zaopatrzonej w poblizu dna w otwór, scianki dennej, oraz z urzadzenia podawczego sluzacego do doprowadzania ukladanych elementów.A sliding box for laying pipes according to patent 69593, is connected with a device for excavation, e.g. from a trench cutter, which is moved vertically by this device and horizontal. It consists of two side walls, the front wall is usually shaped as a bulldozer, from the back wall equipped with an opening near the bottom, from the bottom wall, and from the feeding device for feeding the stacked elements.
Rozwiazania powyzej opisane sa jednak zbyt pracochlonne i czasochlonne przy ich zakladaniu i rozpiera¬ niu scian obudowy jak tez wymagaja uzycia znacznej ilosci materialu, przy czym pierwsze z nich nie zapewniaja bezpieczenstwa ludziom pracujacym w wykopie podczas montazu lub demontazu obudowy.The solutions described above, however, are too laborious and time-consuming to set up and expand the walls of the housing as well as require the use of a significant amount of material, the former of which do not provide for the safety of people working in the trench during assembly or disassembly of the casing.
Istota sposobu wedlug wynalazku polega na tym, ze tarcze deskowania rozpiera sie lub zbliza ku sobie zdalnie, za pomoca medium hydraulicznego lub za pomoca pradu elektrycznego, przy czym obudowa na nowe miejsce w wykopie jest przesuwana za pomoca cofajacej sie koparki, wzglednie przestawiana jest za pomoca dzwigu. Urzadzenie do rozpierania obudowy wykopów waskoprzestrzennych, skladajace sie z rozpór, tarcz przysciennych, przewodów zasilajacych i pompy lub silnika, ma zabudowane pomiedzy przysciennymi plytami rozpory, które wyposazone sa w podciagniki dwustronnego dzialania polaczone za pomoca zasilajacych przewo-2 104635 dów z pompa lub silnikiem.The essence of the method according to the invention consists in the fact that the formwork discs spread apart or come closer together remotely, by means of a hydraulic medium or by means of an electric current, the housing being replaced with a new one the place in the excavation is moved by means of a reversing excavator, or it is moved by means of crane. Device for expanding the lining of narrow-space excavations, consisting of struts, shields walls, power cables and the pump or motor, it is installed between the wall plates struts, which are equipped with double-acting cantilevers connected by means of power cables 104635 pump or motor.
Istota wynalazku jest gwarancja bezpiecznej pracy dla obslugi urzadzenia, gdyz w czasie rozpierania wzglednie zwalniania rozpór nie zachodzi potrzeba przebywania ludzi w wykopie niezabezpieczonym, przy czym uzytkowanie urzadzenia jest proste i latwe.The essence of the invention is a guarantee of safe work for the operating device, because it is during expansion relative to slacken the struts, there is no need for people to stay in an unsecured trench, where the use of the device is simple and easy.
Sposób wedlug wynalazku przedstawiony jest na przykladzie.The method according to the invention is shown by way of example.
Umieszczona w wykopie waskoprzestrzennym skompletowana skrzynia obudowy skladajaca sie z tarcz przysciennych i rozpór, rozpierana jest zdalnie z punktu dyspozycyjnego usytuowanego obok wykopu, poprzez oddzialywanie na rozpory za pomoca medium hydraulicznego. Rozpory mocuje sie do tarcz przysciennych jeszcze przed opuszczeniem obudowy do wykopu, przy czym pracowac moga dwukierunkowo. Po ulozeniu odcinka rurociagu, skrzynia obudowy jest przesuwana za pomoca cofajacej sie koparki, lub w razie potrzeby przestawiana jest za pomoca dzwigu do nowego odcinka wykopu.Completed casing box consisting of shields placed in a narrow-space excavation walls and struts, it is spread remotely from the available point located next to the excavation, through acting on struts with a hydraulic medium. The struts are attached to the wall discs before lowering the casing into the trench, and they can work in two directions. After laying section of the pipeline, the casing box is moved with a reversing excavator, or as needed it is moved by a crane to a new section of the excavation.
Urzadzenie wedlug wynalazku przedstawione jest w przykladowym wykonaniu na rysunku w rzucie okso- nometrycznym.The device according to the invention is shown in an exemplary embodiment in the drawing in an oxo-view. nometric.
Urzadzenie sklada sie z przysciennych plyt 1 obudowy wykonanych z pali szalunkowych, ustawionych na saniach 2 z ksztaltownika stalowego. Wzdluz przysciennych plyt zamocowane sa podrozporowe belki 3., do których zabudowane sa prostopadle cierne rozpory 4 wyposazone w hydrauliczne podciagniki 5 dwustronnego dzialania, polaczone poprzez cisnieniowe przewody 6 z zasilajaca pompa 7, która usytuowana jest poza wyko¬ pem.The device consists of wall panels 1 of the cladding made of formwork piles, placed on 2 sleds made of steel. Supporting beams 3, to the 3, are attached along the wall plates which have perpendicular friction struts 4 equipped with hydraulic 5-sided lifting arms operation, connected via pressure lines 6 to a feed pump 7, which is situated outside the pem.
Po opuszczeniu do wykopu przysciennych plyt 1 sprzegnietych uprzednio ze soba za pomoca ciernych rozpór 4, uruchamia sie pompe 7 zasilajaca w medium hydrauliczne podciagniki 5. Powoduje to ich zadzialanie w kierunku zwiekszenia dlugosci rozpór 4, a tym samym spowoduje docisniecie przysciennych plyt 1 do scian wykopu. Przy demontazu obudowy, uruchomione podciagniki 5 dzialaja w kierunku odwrotnym powodujac zmniejszenie dlugosci rozpór 4, a tym samym zblizenie przysciennych plyt 1 do siebie.After lowering the wall plates 1, previously joined together by means of friction, into the excavation struts 4, the pump 7 is started, feeding the hydraulic lifting units 5 in the medium. This causes their activation in the direction of increasing the length of struts 4, and thus will press the wall panels 1 against the walls excavation. When disassembling the casing, the actuated pullers 5 act in the opposite direction, causing reducing the length of the struts 4 and thus bringing the facing plates 1 closer together.
