Foundation pit supporting structure excavated in horizontal direction and construction method
The invention provides a foundation pit supporting structure excavated in the horizontal direction and a construction method. The supporting structure comprises a horizontal enclosure wall body, an inclined enclosing purlin, an inner support, a starting working well, a receiving working well and a horizontal enclosure wall body end socket wall. The horizontal enclosure wall body, the inclined enclosing purlin and the inner support are sequentially arranged from outside to inside of the foundation pit, and the end enclosure wall of the horizontal enclosure wall body is located in the receiving working well. The horizontal enclosure wall body comprises a plurality of horizontal enclosure piles, and the two ends of the horizontal enclosure piles are anchored into the end socket walls of the horizontal enclosure wall body respectively. The inclined enclosing purlins are arranged on the vertical face of the foundation pit at certain angles at intervals, the inner support is horizontally arranged, and the two ends of the inner support are supported on the enclosing purlins on the two sides of the foundation pit respectively. According to the supporting structure of the height limiting section foundation pit and the construction method of the supporting structure, the requirement for the clear height of a construction site is avoided, and the problem that the supporting construction height of the foundation pit is limited in the process that existing bridges, high-voltage cables and other buildings penetrate downwards is solved.
本发明提供了一种水平方向开挖的基坑支护结构及施工方法。该支护结构包括水平围护墙体、斜围檩、内支撑、始发工作井、接收工作井以及水平围护墙体封头墙。水平围护墙体、斜围檩及内支撑依次从基坑外往内方向布置，水平围护墙体封头墙位于接收工作井内。水平围护墙体包括若干水平围护桩，水平围护桩的两端分别锚入水平围护墙体封头墙。斜围檩在基坑立面上呈一定角度间隔布置，内支撑水平布置，其两端分别支撑在基坑两侧的围檩上。本发明提出的限高段基坑的支护结构及其施工方法，对施工场地处净高无要求，解决了下穿既有桥梁、高压线缆等建构筑物过程中基坑支护施工高度受限的问题。
