High-pile wharf structure for LNG loading and unloading and construction method of high-pile wharf structure
The invention discloses a high-pile wharf structure for LNG loading and unloading and a construction method of the high-pile wharf structure. The high-pile wharf structure comprises pile foundation groups, pile caps, frame beams, cast-in-place joint plates, prefabricated plates and cast-in-place bridge deck slabs. The pile foundation group comprises a plurality of tubular piles which are longitudinally and transversely arranged in rows; the pile cap is correspondingly buckled to the top end of the pipe pile, and a through hole correspondingly communicating with an inner cavity of the pipe pile is formed in the pile cap so that core grouting concrete can be poured into the pipe pile. A high-pile wharf frame is formed by the multiple frame beams, and a pouring gap is formed between the two opposite end faces of every two adjacent frame beams; the cast-in-place joint plate is engaged with the frame beam in the pouring gap; the precast slab is laid on the top surface of the frame beam; the cast-in-place bridge deck is poured on the top face of the frame. The pipe piles are used as the wharf foundation, the pile caps can be solidified with the core grouting concrete to form a whole, the prefabricated plates are used as frame plates and form the wharf upper panel structure with the cast-in-place bridge panel, the pipe piles and the prefabricated cast-in-place are connected to form the high-pile wharf, the construction efficiency is effectively improved, and the construction cost is reduced.
本发明公开了一种用于LNG装卸的高桩码头结构及其施工方法，包括桩基群、桩帽、框架梁、现浇接合板、预制板及现浇桥面板；桩基群包括多根纵、横向均成排布置的管桩；桩帽对应扣合在管桩顶端，桩帽上开设有与管桩内腔对应连通的通孔以向管桩内浇筑灌芯混凝土；多根框架梁形成高桩码头框架，相邻两根框架梁相对的两端面之间具有浇筑间隙；现浇接合板在浇筑间隙内与框架梁咬合；预制板铺设在框架梁顶面；现浇桥面板浇筑在框架顶面。本发明利用管桩作为码头基础，桩帽能够与灌芯混凝土固结形成整体，预制板作为框架板使用并与现浇桥面板形成码头上部面板结构，采用管桩和预制现浇接合的方式形成高桩码头，有效提高了施工效率，降低了建造成本。
