Welding-free underground diaphragm wall anchoring part and foundation pit inner support mounting method
The invention discloses a welding-free underground diaphragm wall anchoring part and a foundation pit inner support installation method. The anchoring part is composed of an anchoring plate, an anchoring sleeve, a plugging part and a connecting part. The anchor plate is pre-buried in the inner side of the diaphragm wall, the anchor plate is connected to the outer side of a reinforcement cage of the diaphragm wall and arranged in the wall surface direction of the diaphragm wall, a positioning piece is installed on the outer side of the reinforcement cage, the thickness of the positioning piece is matched with the thickness of a protective layer of the diaphragm wall, and a plurality of through holes are formed in the anchor plate; the anchoring sleeve is provided with an open end and a closed end which are opposite, and the open end is connected to the end, close to the reinforcement cage, of the penetrating hole. The plugging piece detachably plugs the other end, away from the reinforcement cage, of the penetrating hole. The connecting piece is provided with a first end and a second end which are opposite to each other, after the plugging piece is detached, the first end of the connecting piece can be axially and movably inserted into the penetrating hole and the anchoring sleeve, and the second end of the connecting piece extends out of the underground diaphragm wall to be used for installing a foundation pit inner support. The problem that construction of an embedded steel plate on an existing diaphragm wall is tedious is solved.
本发明公开了一种无须焊接的地连墙锚固件及基坑内支撑安装方法，该锚固件由锚固板、锚固套筒、封堵件和连接件组成；锚固板预埋于地连墙的内侧中，锚固板连接于地连墙的钢筋笼的外侧且沿地连墙的墙面方向设置，钢筋笼的外侧安装有定位件，定位件的厚度适配于地连墙的保护层的厚度，锚固板开设有多个穿孔；锚固套筒具有相对的一开口端和一封闭端，开口端连接于穿孔的靠近钢筋笼的一端；封堵件可拆卸地封堵于穿孔的远离钢筋笼的另一端；连接件具有相对的第一端和第二端，在封堵件拆卸后，连接件的第一端可轴向活动地插设于穿孔和锚固套筒中，连接件的第二端伸至地连墙的外部以用于安装基坑内支撑。本发明解决了现有地连墙上预埋钢板施工繁琐的问题。
