Description
Предлагаемый способ восстановлени взорванных мостовых опор может быть применен к опорам, заложенным на кессонах и имеющим надкессопную опалубку, разрушение которых простираетс ниже торизоита воды.The proposed method of restoring blasted bridge piers can be applied to pillars laid on caissons and having perimeter mold formwork, the destruction of which extends below the torus of water.
Отличительна особенность изобретени заключаетс в том, что вокруг уцелевшей, но поврежденной части опоры, между надкессонной опалубкой и камн ми завала, окружающего опору, забивают щпунтог .ую стенку, затем разбирают поврежденную кладку выще опалубки, уплотн ют щель между щпунтовой стенкой и опалубкой и разбирают поврежденную кладку в пределах опалубки, которую используют вместе со щпунтовой стенкой в качестве ограждени места работ.A distinctive feature of the invention is that around the surviving, but damaged part of the support, between the scaffold formwork and the stones of the dam surrounding the support, they hammer the tongue wall, then disassemble the damaged masonry above the formwork, seal the gap between the tongue wall and the formwork and disassemble damaged masonry within the formwork, which is used together with a shpuntovaya wall as a fence for the work site.
На чертеже показан способ восстановлени мостовых опор.The drawing shows a method for restoring bridge supports.
Работы по восстановлению опор производ тс следующим образом.Work on the restoration of the supports is as follows.
Вокруг уцелевшей, но поврежденной части опоры забиваетс (без предварительной расчистки завалов) металлический шпунт / на глубину 1-2 м ниже верха надкессонной опалубки 2. Забивка может быть произведена сваебойным молотом легкого типа (600 кг).A metal sheet pile / at a depth of 1-2 m below the top of the moldboard 2 is hammered (without clearing the debris) around the surviving but damaged part of the support. The driving can be done by a light-weight piling hammer (600 kg).
Разборка кладки ведетс сначала в щпунте с водоотливом, затем iia границе сохранившейс при взрыве верхней кромки надкессонной опалубки 3 производитс тампонирование щели между щпунтом и опалубкой при помощи мещковины, бумаги или цементным раствором. Пос аедующа разборка кладки ведетс в котловане с оболочкой из надкессонной опалубки старого фундамента, раскрепл емой по мере углублени обычными креплени ми. После разборки кладки до требуемого техническими уСиТОви ми и проектом уровн производитс бетонирование тела подводной части фундамента восстанавливаемой опоры открытым способом при водоотливе, причем стара иадкессонна опалубка используетс , требу дополнительной надстройки лишь в пределах шпунта.The masonry is disassembled first in the drainage pipe, then the border, preserved by the blast of the upper edge of the plank floor 3, which is preserved during the explosion, is used to wrap up the gap between the tongue and the formwork using meshcloth, paper or cement mortar. The subsequent dismantling of the masonry is carried out in a trench with a shell made of the above-cut-off formwork of the old foundation, which is fastened as it is deepened with conventional fastenings. After the masonry is disassembled to the level required by the technical equipment and the project, the body of the underwater part of the basement of the restored support is concreted by the open method with water drainage, and the old and competitive formwork is used requiring an additional superstructure only within the tongue.
Предлагаемый способ имеет следуюнгие преимущества.The proposed method has the following advantages.
а)Забиваетс металлический щпунт на 2-3 м дизель-молотками легкого типа (600 кг).a) A metal sheet is driven into a 2-3 m light-weight diesel hammer (600 kg).
б)Исключаетс предварительна трудоемка подводна расчистка русла у опоры от завалов дл устройства щпунтовых перемычек.b) Preliminary labor-intensive underwater clearing of the bed at the support from blockages for the device of tongue and groove jumpers is excluded.
