Abstract
Navrhovaný postup budovania podzemnej steny umožňuje zvýšenie využitia samotvrdnúcej suspenzie a vytaženého štrkopiesčitého výkopku z podzemnej steny pri výraznom znížení potřeby odvážať výkopok. Uvedeného účelu sa dosiahne takým spósobom, že vytažený štrkopisčitý výkopok z podzemnej steny sa vo vhodnom zariadení zhomogenizuje so samotvrdnúcou suspenziou a vracia sa spať do vopred vyhlbeného úseku ryhy podzemnej steny.Proposed underground building process wall allows increased self-hardening utilization suspension and pulled gravel excavation from the underground wall at a distinctive reducing the need to ditch excavation. This purpose is achieved in such a way that that the pebbled excavation from underground walls in a suitable facility homogenizes with the self-hardening suspension and returning to bed in advance section of an underground wall groove.
Description
Vynález sa týká budován,ia tesniacich podzeminých stien s použitím, samotvrdnúcej suspenzie.The invention relates to the construction of sealing underground walls using a self-curing suspension.
Doterajší postup budovania tesniacich podzemuých stien pomocou samotvrdnúcej suspenzie je charakterizovaný tým, že vytažený materiál vynášaný híbiacim zariadením z ryhy je považovaný za nevhodný a odváža sa na skládky nevhodného materiálu, alebo sa ukládá vedla vyhlbenej ryhy podzemnej steny. Nevýhodou takéhoto postupu je skutečnost, že spolu s výkopkom sa stráca aj časť samotvrdnúcej suspenzie, ktorá je obsiahnutá vo vyhíbenom materiáli v perceratuálnom obsahu asi 10—40 % objemových. Ďalšou nevýhodou takéhoto postupu je, že postup práč je brzděný odvozem výkopku ,na skládky vzdialené obyčejné niekioíko kilometrov, připadne je nevýhodné ukladanie výkopku vedla ryhy z hladiska bezpečnosti práce a tiež z hladiska možnosti zníženia stability podzemnej steny z dovodu priťažeoia vykopaným materiálom.The prior art method of constructing sealing underground walls by means of a self-curing suspension is characterized in that the extracted material carried by the digging equipment from the groove is considered unsuitable and is weighed to landfills of unsuitable material, or is deposited next to the excavated groove of the underground wall. A disadvantage of such a process is that part of the self-hardening suspension, which is contained in the digested material in a perceratic content of about 10-40% by volume, is lost along with the excavation. Another disadvantage of such a procedure is that the washing process is hampered by the removal of the excavation, to landfill distant a few miles away, or the disadvantage of depositing the excavation has been inconvenient in terms of occupational safety and also the possibility of reducing the stability of the underground wall.
Vybudovanie podzemnej steny s použitím samotvrdnúcej suspenzie ako1 tesniaceho materiálu, ktorý má po zatvrdnutí obyčajne podstatné nižšie moduly pretvárnosti može byť v niektorých prípadocih použitia. podzemnej steny nevýhodné, z důvodu nerovnakého sadania okoilitej zeminy a podzemnej steny.The construction of an underground wall using a self-curing suspension as 1 sealing material, which, after hardening, usually has substantial lower modulus of deformation, may be in some cases of use. disadvantage of the underground wall due to the unequal settlement of the loose soil and the underground wall.
Vyššie uvedené nedostatky odstraňuje po* stup budoviania pcdzeminých stien podfa vynálezu, ktorého podstatou je, že štrkoplesčitý výkopok zmáčaný v procese hlbenia samoitvrdnúcou suspenziou sa po homogenizácii vracia, spát do vyhlbeného úseku ryhy, pričom samctvrdnúca suspenzie vytláčená objemom spatné ukládaného výkopku sa odčerpává a používá pri následovnom budovaní dalších úsekov podzemnej steny.The above-mentioned drawbacks are eliminated by the process of building the earth walls according to the invention, which is based on the fact that the gravel trench wetted in the digging process by the self-hardening slurry returns after the homogenization, back to the excavated section by building further sections of the underground wall.
Uložením zhomogenizovaného výkopku do vyhlbenej ryhy sa docieli značné zníženie spotřeby samotvrdnúcej suspenzie, zníži sa alebo úplné odstráni potřeba odvážat výtoor pok a dosiahnu ,sa přibližné rovmaké moduly pretvárnosti tesniaceho materiálu podzemnej steny a okolitej zeminy, pričom sa zachovajú nepriepustné vlastností tesniacej hmoty.By embedding the homogenized trench in the recessed groove, the consumption of the self-curing suspension is considerably reduced, the need to weigh the outlet is reduced or eliminated, and approximately equal modulus of the sealant of the underground wall and surrounding soil is maintained while maintaining the impermeable sealant property.
Příklad použitia:Example of use:
Vyhíbi sa cca 15 m dlhý úsek podzemnej steny so samotvrdnúcou suspenziou. Výkopok z tohoto, úseku sa odvezie na skládku, připadne sa uloží vedl'a ryhy. Týmto sa vytvořil potřebný předstih híbiaceho zariadenia před spatným zasypáním vyhlbeného úseku, ktoré teraz može prebiehať nezávisle od híbiaceho procesu. Pri dálšom postupe budovania. podzemnej steny sa výkopok ukladá do vopred připraveného zariadenia, kde sa zhomogenizuje. Odtialto sa výkopkom postupné zasýpa vopred vyhíbený úsek podzemnej steny tak, aby sa zachoval potřebný předstih, híbiaceho zariadenia, pričom objem samotvrdnúcej suspenzie vytláčený výkopkom sa přečerpává do právě híbeného úseku podzemnej steny.A 15 m long section of the underground wall with a self-hardening suspension is heated. The excavation from this section is taken to the landfill or placed next to the trench. This provides the necessary advance of the digging device before the backfilling of the recessed section, which can now be run independently of the digging process. In the further construction process. In the underground wall, the excavation is stored in a pre-prepared facility where it is homogenized. From there, the excavated section of the underground wall is gradually filled with the excavation so as to maintain the necessary advance of the digging device, whereby the volume of the self-hardening suspension displaced by the excavation is pumped into the just collapsed section of the underground wall.
