Complicated irregular staged implementation deep foundation pit supporting excavation structure and construction method
The invention relates to a complex irregular staged implementation deep foundation pit support excavation structure and a construction method. The construction method comprises the steps that (1) steel pipe-steel plate-steel pipe support combined support construction is conducted; (2) double-row steel pipe-steel plate combined support construction is carried out; (3) cast-in-situ bored pile-double-row reinforced cement soil pile anchor combined support construction is carried out; 4) constructing a reinforced concrete support formwork; (5) reinforcing construction of a walkway plate of the soil outlet; and 6) earth excavation construction. The steel pipe-steel plate-steel pipe support combined supporting structure has the beneficial effects that in the steel pipe-steel plate-steel pipe support combined supporting structure, the retractable type fast dismounting and mounting steel pipe bent frame arranged on the lower portion of the steel pipe inclined support can be repeatedly used and is convenient to dismount and mount, and benefits are good; in the double-row steel pipe-steel plate combined supporting structure, the adjustable inner supporting frame arranged between the double-row steel pipe piles can adjust the two rows of steel pipe piles by replacing the replaceable adjusting plates with different sizes, and the applicability is high.
本发明涉及复杂不规则分期实施深基坑支护开挖结构及施工方法，包括步骤：1)钢管‑钢板‑钢管撑组合支护施工；2)双排钢管‑钢板组合支护施工；3)钻孔灌注桩‑双排加筋水泥土桩锚组合支护施工；4)钢筋混凝土支撑支模施工；5)出土口走道板加固施工；6)土方开挖施工。本发明的有益效果是：钢管‑钢板‑钢管撑组合支护结构中，钢管斜撑下部设置的收放式快速拆装钢管排架可重复使用且拆装方便，效益较好；本发明的双排钢管‑钢板组合支护结构中，双排钢管桩间设置的可调式内撑架可通过更换不同尺寸的可更换调节板，来调节两排钢管桩，适用性较强。
