Miniature engineering pile structure and construction method thereof
The invention relates to a micro engineering pile structure and a construction method thereof. The micro engineering pile structure comprises a plurality of pile holes formed in the lower portion of a pipe gallery structure to be formed; the pile casing is inserted into the pile hole; the core pipe penetrates through the pile casing, a plurality of grouting holes are formed in the side wall of the core pipe at intervals, and the interior of the core pipe and a gap between the core pipe and the pile casing are filled by grouting the core pipe. The problem that existing cast-in-situ bored piles and prestressed pipe piles are high in cost is effectively solved, the miniature engineering piles are used for supporting the pipe gallery, the size requirement can be met, reliable bearing capacity can be provided, the construction cost is reduced, and the construction quality is guaranteed.
本发明涉及一种微型工程桩结构及其施工方法，包括：形成于待形成的管廊结构的下方的若干桩孔；插设于桩孔的护筒；以及穿设于护筒的芯管，芯管的侧壁间隔开设有若干注浆孔，通过向芯管内注浆，以填充芯管内部和芯管与护筒之间的间隙。本发明有效地解决了现有钻孔灌注桩、预应力管桩成本较高的问题，利用微型工程桩支撑管廊，不仅能够满足尺寸要求，还能提供可靠的承载力，降低了施工成本，保证了施工质量。
