Embedded load-box family · Project evidence
Bidirectional pile load-box family
Ougan lists several embedded load-box designs for different pile and test contexts. This family reference has no universal capacity or placement; the selected device belongs to an approved project programme.
The design labels describe different installation contexts
| Listed design | Stated typical context | Question for the proposed arrangement |
|---|---|---|
| Ring-band | Friction piles generally above 1.2 m diameter | Actual cage, passage and arrangement drawing |
| Combined | Test piles generally 1.2 m and above; loading-unit combination | Selected number/configuration of units and calibrated relationship |
| Annular | Test piles generally 0.6–1.2 m | Actual outline, central passage and pile interface |
| Integral | Rock-socket/end-bearing, manually excavated and plate-test contexts; bottom installation described | Engineer-approved placement and required test objective |
| Force-enhanced | Small diameter / high loading requirement | Exact rated output and unit calibration, not a generic multiplier |
| Steel-pipe / prestressed-pipe | Dedicated pipe-pile arrangements | Actual installation/handling structure and project drawing |
| Instrumented “smart” | Additional displacement/load monitoring | Included sensors, data and monitoring service duration |
These contexts are published on the actual product page. [1] They do not calculate a box’s placement or capacity for a specific foundation. Ask the responsible engineer to review the proposed equipment using the actual pile and ground information.
Separate model designation from geometric specification
The linked 2021 document distinguishes loading designation from a specification describing pile/box geometry and loading-unit arrangement. [2] Preserve both in the order and the controlled installation drawing.
- Load and travel
- Selected rated output, pressure, stroke and applicable unit test/acceptance records.
- Geometry and integration
- Actual box/cage/pile dimensions, concrete passages, attachments, pipes and instruments.
- Identity
- Maker, exact model/specification, serial, drawing revision and intended project/pile.
The website’s historic 300,000 kN test claim and enhanced-design multiplier are not assigned to this family as an available selected-unit rating. No capacity is inferred from the catalogue image.
Verify what arrived before it is embedded
| Gate | Record to reconcile | Unresolved question |
|---|---|---|
| Unit identity | Nameplate, full code/specification, serial and drawing | Does the received device match the approved order? |
| Calibration and inspection | Actual record with equipment identity, issuer, scope and conditions | Which unit/assembly does the evidence cover? |
| Delivery | Conformity document, instructions, packing list and included accessories | Are the installation and measurement items complete? |
| Installation release | Approved placement/instrument arrangement and responsible sign-off | Who accepts the as-installed record? |
The linked document separately addresses factory/type inspections, pressure-test video/paper records and nameplate/delivery documents. [2] A normative requirement is not proof the delivered device fulfilled it. The homepage’s “100%” calibration statement is also a supplier claim until the actual record is checked. [3]
Agree the evidence and approval timing before subsequent construction makes inspection more difficult. This checklist does not authorize installation or provide a field pressure-testing procedure.
Equipment measurements are not the final foundation conclusion
- Approve the programme. Objectives, pile/ground information, equipment arrangement, instruments, method and applicable project requirements.
- Record the work. As-installed identity, measurement connections, actual test data, conditions and deviations.
- Issue and review the report. Named competent organisation, interpretation, limitations and any separately approved post-test work.
ASTM D8169/D8169M-26 concerns bidirectional static axial compression testing; its scope distinguishes test results from assured long-term foundation behaviour. [4] The responsible professionals must determine the applicable method and interpretation. No simple addition of catalogue forces or sensor readings is offered here as a bearing-capacity calculation.
Does buying the box include a recognised test report?
The supplier advertises equipment, installation and data services separately. Identify the actual report issuer, scope and project-accepted qualifications in the quotation.
Is grouting or long-term monitoring included?
Grouting is another service, and the instrumented design describes monitoring capability. Confirm the supplied hardware, actual service scope, duration and completion evidence; neither is automatic with every load box.
