Pipe-jacking construction foundation pit fence and enclosure construction method for riverbed sandy gravel section
The invention discloses a riverbed sandy gravel section pipe jacking construction foundation pit fence which comprises a baffle and a connecting pile, the baffle comprises a vertical plate and an inserting plate, the bottom of the vertical plate is connected to the top of the inserting plate, a baffle inserting groove is formed in the side wall of the vertical plate, and a baffle inserting strip is arranged on the side wall opposite to the baffle inserting groove; the baffle plate insertion strips are inserted into the baffle plate insertion grooves of the adjacent baffle plates; the connecting pile comprises a connecting column and an inserting column, the top of the inserting column is connected to the bottom of the connecting column, an inserting column inserting groove is formed in the side face of the inserting column, and an inserting column inserting strip is arranged on the side face adjacent to the inserting column inserting groove; the two baffles are located on the two adjacent side faces of the connecting pile correspondingly, the baffle insertion strips of one baffle are inserted into the insertion column insertion grooves, and the insertion column insertion strips of the other baffle are inserted into the baffle insertion grooves of the other baffle. The invention further discloses an enclosure construction method. The problem of construction difficulty caused by pit wall collapse and underground water backflow is solved, and efficient pipe jacking operation can be guaranteed.
本发明公开了一种河床砂卵石地段顶管施工基坑围栏，包括：挡板和衔接桩，挡板包括：竖板和插板，竖板的底部连接在插板的顶部，竖板在侧壁上设置有挡板插槽，与挡板插槽相对的侧壁设置有挡板插条，挡板插条插接在相邻挡板的挡板插槽内；衔接桩包括：衔接柱和插柱，插柱的顶部连接在衔接柱的底部，插柱的侧面设置有插柱插槽，与插柱插槽相邻的侧面设置有插柱插条；两个挡板分别位于衔接桩的两个相邻侧面，一个挡板的挡板插条插接在插柱插槽内，插柱插条插接在另一个挡板的挡板插槽内。本发明还公开了一种围护施工方法。本发明解决了坑壁坍塌、地下水倒灌造成的施工困难问题，能够保障顶管作业高效进行。
