Fabricated foundation pit pile-beam-wall-anchor rod prestressed enclosure structure and construction method
The invention discloses an assembly type foundation pit pile-beam-wall-anchor rod prestressed enclosure structure technical system and a construction method. The construction method comprises the following steps of a, measuring, paying off, pile fixing and prefabricated pile driving, b, earth excavation to the elevation position of the bottom of a prefabricated beam, c, prefabricated beam hoisting, d, prestressed tendon perforating, tensioning and anchoring, e, grouting of the inner side of the prefabricated beam, anchor rod driving on a beam body, and e, construction of a prefabricated pile-beam-wall-anchor rod prestressed enclosure structure. (f) continuing to excavate earthwork to the elevation position of the bottom of the next prefabricated beam; (g) continuing to hoist the prefabricated beam, perforate the pre-stressed tendon, stretch and anchor; (h) hoisting the prefabricated shear wall plate and install a double-row flat-hole T-shaped steel plate supporting strip; (f) grouting after the prefabricated shear wall plate and arranging an anchor rod; and (j) installing a splayed steel support, and (k) repeating the step (b) to the step (j) until the construction of the whole assembled foundation pit support structure is completed. And l, acceptance and monitoring. According to the technical scheme, layered, segmented, part-by-part earth excavation and integrated prefabrication assembly are followed, the structural design is reasonable, the bearing capacity is high, the assembly rate is high, and the construction speed is high.
本发明公开了装配式基坑桩‑梁‑墙‑锚杆预应力围护结构技术体系及施工方法，包括以下步骤：a.测量放线定桩位，打设预制桩，b.土方开挖至预制梁底标高处，c.吊装预制梁，d.预应力筋穿孔、张拉与锚固，e.预制梁内侧注浆、梁身打设锚杆，f.继续开挖土方至下一预制梁底标高处，g.继续吊装预制梁，预应力筋穿孔、张拉与锚固，h.吊装预制剪力墙板，安装双排扁孔T型钢板支撑条，i.预制剪力墙板板后注浆、锚杆打设，j.安装八字形钢支撑，k.重复步骤b至步骤j，直至完成整个装配基坑围护结构施工，l.验收与监测。本发明技术方案遵循“分层、分段、分部位土方开挖，一体化预制装配”，结构设计合理、承载力强，装配率高，施工速度快。
