Pile foundation pouring device and construction method thereof
The invention discloses a pile foundation pouring device and a construction method thereof. The device comprises a slurry blocking protective cylinder, wherein the slurry blocking protective cylinder comprises a protective cylinder base body and a plurality of slurry blocking plates, the protective cylinder base body and the slurry blocking plates are connected through connecting pieces, and a cylinder is fixedly arranged on a steel reinforcement cage. The construction method comprises the following steps that S1, the number of caves and the height of each layer of caves are surveyed, and the number and the length of the slurry blocking protective cylinders needing to be installed are determined; S2, the slurry blocking protective cylinder is installed on the steel reinforcement cage; S3, the slurry blocking protective cylinder is placed into a pile hole along with the steel reinforcement cage; and S4, concrete is poured, the slurry blocking plates seal the space between the protective cylinder base body and the pile wall, and the concrete is continuously poured, so that the concrete reaches the design elevation of the pile top. According to the pile foundation pouring device and the construction method thereof, the device realizes low-cost, safe and reliable concrete pouring, and the stress structure of the pile foundation is improved; and by the adoption of the construction method, the defects existing in a backfilling method, a steel protective cylinder follow-up method and a grouting method can be overcome.
本发明公开了一种桩基浇筑装置及其施工方法，装置包括挡浆护筒，挡浆护筒包含护筒基体、若干挡浆板，护筒基体、挡浆板之间通过连接件相连，圆筒固设在钢筋笼上；施工方法，包括以下步骤：步骤S1，勘测洞穴的数量以及每层洞穴的高度，确定需安装挡浆护筒的数量和长度；步骤S2，将挡浆护筒安装在钢筋笼上；步骤S3，将挡浆护筒随钢筋笼下放至桩孔内；步骤S4，浇筑混凝土，挡浆板封闭护筒基体与桩壁的空间，并继续浇筑混凝土，使得混凝土到达桩顶设计高程。本发明提供一种桩基浇筑装置及其施工方法，这种装置实现低成本、安全可靠地完成混凝土浇筑，改善了桩基受力结构；采用这种施工方法，可解决回填法、钢护筒跟进法和注浆法所存在的缺陷。
