1. Overall Solution Overview

This solution adopts embedded anchor bolt foundation structure, separate foundation construction and stand assembly. Compared with direct buried pole type, it features higher stability, convenient later maintenance, easy replacement of basketball stand components, and strong anti-overturn performance. The whole set meets outdoor long-term safe use standards in windy, cold and high-temperature regions.

2. Pre-Construction Preparation

2.1 Site Positioning Standard

The center of concrete foundation shall be ≥600 mm outside the basketball court end line.

Ensure horizontal distance between vertical pole and backboard rear ≥1200 mm to avoid athlete collision.

Check underground pipelines (electric wire, water pipe, gas pipeline) before excavation to prevent damage.

2.2 Tools & Materials List

Tools: Shovel, tape measure, spirit level, wooden support frame, concrete vibrator, wrench, marking line, lifting equipment

Materials: Gravel cushion, C25/C30 commercial concrete, embedded anchor assembly (hot-dip galvanized), anti-rust grease, lock washers

2.3 Product Inspection

Check anchor plate, anchor bolts, main pole, support arm, backboard, rim and all fasteners; confirm no deformation, crack or thread damage.

3. Foundation Construction Scheme (Core Standard)

3.1 Excavation Specification

Minimum pit dimension: 700mm(L) ×700mm(W) ×800mm(D)

Recommended standard specification (school & public projects): 800mm×800mm×1000mm

Frost areas (North China including Hebei): Pit depth ≥1000–1200mm (below frost penetration line)

Windy open sites / soft soil foundation: Expand pit size to 1000mm×1000mm×1200mm

3.2 Cushion Treatment

Compact the pit bottom evenly, lay 100 mm thick graded gravel as drainage cushion to prevent foundation water soaking and frost heave.

3.3 Embedded Anchor Frame Positioning

Place the galvanized anchor assembly into the pit, suspend with wooden supports; do not directly rest on gravel.

Adjust horizontal level: horizontal tolerance ≤3 mm.

Coat anchor bolt threads with anti-rust grease and wrap with adhesive tape to avoid concrete contamination.

Fix supports firmly to prevent displacement during concrete pouring.

3.4 Concrete Pouring

Concrete grade: Minimum C25; C30 is strongly recommended for high-frequency use venues.

Pour concrete in layers, fully vibrate to eliminate internal voids.

Make a slight outward slope on the top concrete surface to drain rainwater away from the pole base.

Control foundation top surface 0–10 mm lower than finished ground.

3.5 Concrete Curing (Mandatory)

Minimum curing period: 7 days

Suggested curing period for outdoor projects: 10 days

❌ Do not install the main pole or bear any impact load before full curing. Early operation will cause foundation offset and stand tilting.

4. Basketball Stand Assembly Process

Remove protective tape and clean anchor bolt threads.

Hoist the main vertical pole, align flange holes with anchor bolts.

Tighten nuts diagonally and gradually to ensure uniform stress.

Use spirit level to calibrate verticality of the pole; vertical deviation ≤1‰.

Install support arm, backboard fixing bracket.

Mount backboard; adjust flatness and fastening torque.

Install basketball rim. Standard height: 3050 mm from finished ground to the top edge of rim.

Hang the basketball net.

5. Safety Acceptance Standard

Retighten all bolts 24 hours after assembly.

Shake the stand manually; no obvious loose shaking or abnormal noise.

Anti-overturn safety factor ≥1.5, suitable for regular dunking impact.

Wind resistance level: Grade 8 for open outdoor venues.

6. Long-Term Maintenance Suggestions

Check bolt tightness every 3 months, retighten loose fasteners.

Regularly inspect surface coating; touch up anti-rust paint if scratches appear.

Clear accumulated water around the foundation to avoid long-term corrosion of anchor components.

7. Key Advantages of This Installation Solution

Galvanized embedded anchor set, strong rust resistance for outdoor service.

Standardized concrete foundation design, effectively prevent tipping risks.

Separated foundation and stand structure; easy to replace basketball stand without breaking concrete.

Strict curing process avoids foundation deformation caused by frost heave and temperature variation.
