The tie rod connector is a plastic component also known as a spool, wing‑type, or end‑fix. It is a critical part of the plastic tie rod system, serving as an intermediary between the tie rod cone and the corrugated pipe.

Important Notes on the Plastic Tie Rod Waterstop Connector

The plastic tie rod waterstop connector plays a critical role in the tie rod assembly. Removing this connector can deform the corrugated plastic pipe, preventing the stoppers from being properly positioned. This can lead to leaks through the holes left by the tie rod.

Therefore, to maintain the quality and performance of the waterproofing system, the use of the plastic tie rod connector is essential. This component ensures the proper alignment and secure positioning of the tie rod parts, helping to prevent future issues.

Consumption of the Plastic Tie Rod Waterstop Connector

For each plastic tie rod waterstop, two plastic connectors are required. These connectors are placed between the corrugated pipe and the tie rod cones, playing an important role in the structure and proper functioning of the assembly.

Storage and Handling of the Plastic Tie Rod Connector

Conditions: Keep away from frost, excessive heat, and prolonged direct sunlight
Optimal Temperature: +10 °C to +30 °C

The plastic tie rod spool is made from polypropylene (PP) or high‑density polyethylene (HDPE) — plastics known for their high strength, chemical stability, and excellent resistance to the concrete environment.

Physical Specifications:

Cylindrical or spool‑shaped overall form with steps or flanges on both sides, positioned between the corrugated pipe and cone
Precisely designed to lock into place at the connection between the corrugated pipe and cone, preventing movement during concrete pouring
Strong structure resistant to pressure and impact, maintaining its shape against the hydrostatic force of fresh concrete
Helps center and stabilize the tie rod, contributing to the structural integrity of the concrete wall
Lightweight, enabling quick installation without special tools

Chemical Specifications:

Highly resistant to alkalis, corrosive agents present in concrete, moisture, and aggressive ions (such as chlorides)
Polymer structure ensures no harmful reactions with concrete or reinforcement bars
Often contains UV stabilizers and antioxidants for increased durability against sunlight and high temperatures (up to about 130 °C without deformation)
Non‑corrosive, non‑toxic, and chemically inert in construction and industrial environments
Not biodegradable in nature, but recyclable like other polymer components

How to Use the Plastic Tie Rod Connector (Spool/Wing‑Type)

The plastic tie rod connector is an essential component in the tie rod system. During assembly, it connects on one side to the plastic corrugated pipe and on the other side to the plastic tie rod cone.

After concrete pouring, the tie rod cone is removed from the hardened concrete, while the connector (wing‑type or spool) and the corrugated pipe remain embedded in the structure.

The primary function of the wing‑type connector is to hold and stabilize the tie rod cone within the concrete.

This installation method helps maintain the strength and stability of the structure and prevents the leakage of liquids.
