Static load test counter-force device for pull rod type steel bar pile-loading foundation pile
The invention discloses a pull rod type reinforcing steel bar pile-loading foundation pile static load test counter-force device, and relates to the technical field of foundation pile compression resistance static load tests, the pull rod type reinforcing steel bar pile-loading foundation pile static load test counter-force device comprises a test pile, a jack, an anchor pile, a main beam and an auxiliary beam, the jack is installed on a steel bracket on the test pile, and the upper portion of the jack abuts against the lower surface of the main beam through the steel bracket; anchor bars are respectively hung at the left and right ends of the main beam; the bottoms of the anchor bars are fixedly connected with anchor piles; the main and auxiliary beams are perpendicularly arranged in the middle of the upper surface of the main beam, the balance structure is fixedly installed at the near end of the main and auxiliary beams, the auxiliary and auxiliary beams are installed at the far end of the main and auxiliary beams, a series of upper pressure steel sets are evenly fixed to the auxiliary and auxiliary beams, and a series of lower pressure steel sets are arranged at the corresponding positions of the upper surface of a sleeper on the ground. A front pull rod and a rear pull rod are symmetrically and fixedly installed at the front and rear ends of the upper pressure steel set correspondingly. Existing engineering piles can be fully utilized as anchor piles, local materials are used, on-site reinforcing steel bars are used for pile loading, the site excavation workload is small, the cost is saved, and the pile loading time is short.
本发明公开了一种拉杆式钢筋堆载基桩静载试验反力装置，涉及基桩抗压静载试验技术领域，包括试验桩、千斤顶、锚桩、主梁和副梁，千斤顶安装在试验桩上的钢制托架上，千斤顶上部通过钢制托架顶在主梁的下表面，主梁的左右两端分别吊挂有锚筋，锚筋底部与锚桩固定连接；主副梁垂直设于主梁上表面中部，且主副梁的近端固定安装有平衡结构，辅副梁安装在主副梁的远端，辅副梁上均匀固定有一系列的上压力钢组，在地面的枕木上表面对应位置设有一系列的下压力钢组；上压力钢组的前后端分别对称固定安装有前拉杆和后拉杆。本发明可以充分利用现有工程桩作为锚桩，就地取材，利用现场钢筋作为堆载，场地开挖工作量小，节省费用，堆载时间较短。
