3D deformation, segmented & recoverable, multi-mode layout 三维变形 · 分段可回收 · 多模式布设
The RIPI 2010S measures displacement in X, Y and Z simultaneously through a spine-structure array of rigid sensing segments and flexible hinges. AutoID + RS485 chain up to 128 segments on a single cable — vertical in a borehole, horizontal in a trench, or ring-laid around a tunnel section. RIPI 2010S 采用刚性测量节段 + 柔性铰链的脊柱结构，同时测量 X、Y、Z 三个方向的位移。AutoID + RS485 一根线最多串联 128 节——可竖直入孔、水平埋设或沿隧道断面环向布设。

A Spine of Rigid Segments and Flexible Joints刚柔交替的“脊柱”结构
Rigid sensing tubes alternate with flexible joints — the tubes measure, the joints take the deformation. Each rigid segment carries a 3-axis MEMS sensor that measures its own orientation in space across 0–360°; chaining every segment's vector end-to-end reconstructs the full 3D deformation shape of the borehole or structure.硬管与软管刚柔交替：硬管是测量节段，内置三轴 MEMS 传感器，在 0~360° 范围内测量自身空间姿态；软管是变形节段，承担弯曲。将每节姿态向量首尾相接，即可重构钻孔或结构的完整三维变形形态。
01 · Sense01 · 感知
Every rigid segment measures its 3-axis orientation across 0–360° and logs its own temperature in real time.每节硬管在 0~360° 范围内测量三轴姿态，并实时记录本节温度。
02 · Flex02 · 变形
Flexible joints between segments take the bending, so measurement and deformation are cleanly separated.节间软管承担弯曲，测量对象与容许变形对象彻底分离。
03 · Reconstruct03 · 重构
Segment vectors are chained into the 3D shape curve; torsion correction aligns all segments to one coordinate system, better than 0.5°.节段向量逐节相加得到三维形状曲线；扭转校正将所有节段对齐统一坐标系，精度优于 0.5°。
A Continuous Profile, One Point per Segment连续剖面 · 每节一个测点
Every rigid segment is a measurement point, so the array returns a continuous displacement profile with no blind spots — and because acquisition is automated, the deformation trajectory can be replayed in real time as it develops. 每节硬管就是一个测点，阵列输出连续无盲区的位移剖面；采集全自动进行，形变轨迹可实时回放。

Built around two core capabilities 两大核心特色
- ✓Segmented & recoverable分段可回收
Segmented design → flexible on-site assembly → dismantled & recovered at project end → transported to the next project → lower hardware amortization cost.分段式设计 → 现场灵活拼接 → 项目结束可拆卸回收 → 运输至下一项目 → 降低硬件摊销成本。
- ✓Torsion correction扭转校正
Built-in algorithm detects axial torsion → auto-computes azimuth → aligns to a unified coordinate system → correction accuracy better than 0.5°.内置算法检测轴向扭转 → 自动计算方位角 → 对齐统一坐标系 → 校正精度优于 0.5°。
- ✓AutoID + RS485 busAutoID + RS485 总线
One cable chains up to 128 segments with automatic addressing — simple wiring, open protocol, ready for any logger or platform.一根线串联 128 节、自动编址——布线简单、协议开放，可接入任意采集器与平台。
Installation: Vertical & Horizontal Paths安装：垂直与水平两条路径
The deployment modes above tell you where the array goes — this is how it gets there. Vertical (chained in casing) and horizontal (trench-laid) follow two entirely different procedures that are not interchangeable: confirm which one applies before work starts.上文的布设方式决定阵列“放在哪”，这里是“怎么放进去”。垂直（管内串接）与水平（沟槽铺设）是两套截然不同、互不通用的规程——进场前先确认现场属于哪一类。
Vertical — chained inside the casing垂直安装——测斜管内串接
- 1Prepare the casing测斜管准备
Seal the casing bottom and fill the casing with clean water.测斜管底端封口，管内注入清水。
- 2Connect the controller连接控制器
The lead-out cable at the top of the array connects to the controller.SAA 顶部接出线，连接控制器。
- 3Lower top-down自上而下放入
Lower the array into the casing from the top; slight bending is allowed at each flexible joint.自上而下放入测斜管，每节软管位置允许微弯。
- 4Fix and protect固定与防护
Fix the array at the top and fit a protective device on the casing mouth.顶部固定，管口加保护装置。
- 5Casing twist self-corrects管体扭转自动校正
If the casing twists during monitoring, the rotation it imparts to the array is corrected automatically by the torsion-correction algorithm.监测过程中若测斜管发生扭转，由其带动柔性测斜仪产生的扭转角度自动校正。
Horizontal — trench + PVC conduit水平安装——沟槽 + PVC 导管
Ships as a kit: PVC conduit matched to the run, end caps and mouth fittings, traction wire rope and marker posts.安装套装包含：与长度匹配的 PVC 导管、端盖与管口配件、牵引钢丝绳、标志杆。
- 1Excavate the trench开沟
Trench bottom flat and level, length matched — avoid local dips.沟底平整、长度匹配，避免局部下凹。
- 2Lay the conduit铺管
Every PVC conduit seam must be sealed with PVC primer + cement — otherwise water gets in later.PVC 导管接缝必须使用胶水 + 底漆密封，否则后期进水。
- 3Pull in — never push牵引——严禁推动
Pull the array into the conduit with the wire rope from one end. Pushing destabilizes the flexible joints and damages the hinges.用钢丝绳从一端牵引拉入导管。推动会导致软管失稳、损伤铰链。
- 4Check every bend radius核查弯曲半径
At any curve the bend radius must stay ≥ Rmin (about 0.3 m); any section below the limit is re-laid.任何弯曲处半径必须 ≥ Rmin（约 0.3m），不达标的整段重做。
- 5Finish & seal收尾密封
Waterproof the lead-out end and seal the end caps.出线端做防水处理，端盖密封。
