Grouting type anchoring foundation with inner bag and outer bag and construction method thereof
The invention discloses a grouting type anchoring foundation with an inner bag and an outer bag and a construction method thereof. The grouting type anchoring foundation comprises steel pipes, an inner bag, an inner grouting body, an outer bag, an outer grouting body, a plurality of holes, an anchor head, an annular end and an anchor chain. Bag openings are arranged in the two ends of the inner bag and the two ends of the outer bag respectively, the bag openings in the two ends of the inner bag are bound and fixed to the steel pipes located at the two ends of the multiple holes respectively, and the bag openings in the two ends of the outer bag are bound and fixed to the two ends of the steel pipes respectively. The steel pipes and the inner bag are filled with the inner grouting body, andthe space between the inner bag and the outer bag is filled with the outer grouting body. The inner bag and the outer bag are arranged, the strength of the inner grouting body is greater than that ofthe outer grouting body, the requirement for stress concentration when anchor chain tension acts on the steel pipes is met, the inner grouting body and the outer grouting body are not liable to damage and fail under the action of loads and the safety of the grouting type anchoring foundation is improved.
本发明公开了一种具有内囊与外囊的注浆式锚泊基础及其施工方法，包括有钢管、内囊袋、内部注浆体、外囊袋、外部注浆体、多个孔洞、锚头、环形端头和锚链；内囊袋和外囊袋的两端均设有袋口，内囊袋的两端袋口分别绑扎、固定在位于多个孔洞两端位置的钢管上，外囊袋的两端袋口分别绑扎、固定在钢管的两端；内部注浆体填充在钢管和内囊袋的内部，外部注浆体填充在内囊袋与外囊袋之间。本发明分别设置内囊袋和外囊袋，并使内部注浆体的强度大于外部注浆体的强度，适应了锚链拉力作用在钢管上时的应力集中需要，使内部注浆体和外部注浆体在荷载作用下不易发生破坏与失效，提高了注浆式锚泊基础的安全性。
