Construction method of gravity type road and bridge integrated overhanging foot bridge in limited space
The invention discloses a construction method of a gravity type road and bridge integrated overhanging foot bridge in a limited space, and relates to construction of a pedestrian overpass with a river-crossing bridge underneath passing and transverse passing, the construction method comprises the following steps: (1) counterweight block construction: slope protection is excavated at river embankment slope protection parts at two sides of the crossing direction of the river-crossing bridge respectively, and counterweight block steel bars are bound at the excavation parts; (2) erecting a support frame and a template: arranging an overhanging part connected with balancing weights on the two sides at the underpass of the river-crossing bridge, and erecting an overhanging part support frame; (3) binding a reinforcement cage: extending one ends of the reinforcements and integrally binding the reinforcements with upper reinforcements of the balancing weight reinforcements; (4) mold closing is conducted, specifically, a balancing weight mold plate and a cantilever end mold plate which are used for concrete pouring are erected; (5) concrete pouring and demolding are conducted, specifically, integrated concrete pouring is conducted on the enclosed pouring space, and demolding is conducted after forming; the balance weight foundation and the cantilever platform can be formed in a one-time pouring mode, construction operation can be completed in a limited space, and the problem that the safety of an existing building is affected is solved.
本发明公开了一种受限空间内重力式路桥一体悬挑人行桥施工工法，涉及跨河桥下穿横向通行的人行天桥施工，包括以下步骤，(1)配重块施工：在跨河桥横穿方向的两侧河堤护坡处分别开挖护坡，并在开挖处绑扎配重块钢筋；(2)搭设支撑架及模板：在跨河桥下穿处设置连接两侧配重块的悬挑部，搭设悬挑部支撑架；(3)绑扎钢筋骨架：将钢筋一端延伸与配重块钢筋的上部钢筋一体绑扎；(4)合模：搭设用于混凝土浇筑的配重块模板及悬挑端模板；(5)混凝土浇筑及脱模：对围合的浇筑空间进行一体混凝土浇筑，成型后脱模；本发明中的配重基础及悬挑平台可一次性浇筑成型，能够在受限空间内完成施工作业，不会对既有建筑造成安全性影响的问题。
