Description
Изобретение относитс к области строительства , в частности к способам усилени и реконструкции фундаментов существующих зданий, сооружений.The invention relates to the field of construction, in particular, to methods for strengthening and renovating the foundations of existing buildings and structures.
Известные способы подведени фундамента под существующие здани , сооружени путем отрывки котлована и проходки из него под существующим фундаментом горизонтальной выработки с последующим погружением из нее свай требуют креплени выработки и не исключают возникновени осадок существующих зданий, сооружений при производстве работ.Known methods of laying the foundation for existing buildings, structures by extracting a pit and sinking from it under the existing foundation of horizontal excavation and subsequent sinking of piles from it require fastening the excavation and do not exclude the occurrence of sediment in existing buildings and structures during production.
Дл исключени креплени выработки и возникновени осадок существующих зданий, сооружений при произвОлТ,стве работ по предлагаемому способу горизонтальную выработку образуют продавливанием из котлована полых секций с одновременным извлечением грунта из их полости.In order to avoid mounting workings and the occurrence of sediments of existing buildings, structures during production of the proposed method, horizontal generation is formed by forcing hollow sections out of the excavation while simultaneously removing soil from their cavity.
На фиг. 1 изображен продольный разрез котлована и горизонтальной выработки; на фиг. 2 - погружение свай из выработки; на фиг. 3 - разрез по А-А на фиг. 2.FIG. 1 shows a longitudinal section of the pit and horizontal development; in fig. 2 - immersion of piles from the mine; in fig. 3 is a section along A-A in FIG. 2
Свайный фундамент под существующие сооружени подвод т следующим образом.The pile foundation for the existing structures is summarized as follows.
Возле существующего фундамента / отрывают котлован 2 в ограждении 3. В котловане 2 устанавливают домкраты 4, домкратные балки 5. упорное устройство 6 и направл ющие подмости 7. Полые секции 8 подают в котлован 2 и вдавливают их под существующий фундамент / домкратами 4.Near the existing foundation / tear off the pit 2 in the fence 3. In the pit 2, place the jacks 4, jack beams 5. The stop device 6 and the scaffold guide 7. The hollow sections 8 are fed into the pit 2 and pressed them under the existing foundation / jacks 4.
По мере вдавливани секций 8 грунтAs the sections are pressed 8, the ground
внутри них разрабатываетс и извлекаетс .inside of them is developed and retrieved.
После задавливани секций 8 на заданнуюAfter crushing sections 8 on a given
длину в выработку подают сваи 9. В местахthe length of the production serves pile 9. In places
расположени свай 9 в донной части секцийthe location of the piles 9 at the bottom of the sections
8 устраивают отверсти 10. Сваи 9 погружают вдавливанием домкратами // короткими звень ми, объедин их стыками 12. Тип свай, их материал выбирают в зависимости от категории грунта.8 arrange holes 10. Piles 9 are immersed by indentation with jacks // short links, combining them with joints 12. The type of piles, their material is chosen depending on the category of soil.
Предмет изобретени Subject invention
Способ подведени фундамента под существующие здани и сооружени путем отрывки котлована н проходки из него под существующим фундаментом горизонтальной выработки с последующим погруи ением из нее свай, отличающийс тем, что, с целью исключени креплени выработки и возникновени осадок существующих зданий, соорулсений при производстве работ, горизонтальную выработку образуют посредством продавливани из котлована нолых секций с одновременным извлечением грунта из их полости.The method of laying the foundation for existing buildings and structures by extracting a pit and sinking from it under the existing foundation of horizontal excavation followed by plunging piles out of it, characterized in that, in order to eliminate the reinforcement of production and sedimentation of existing buildings, the construction the production is formed by forcing out of the sections from the trench with simultaneous extraction of the soil from their cavity.
