Common Pipeline and Road Design and Construction in Area A of the Macao New Town Reclamation Area – North and Central Districts
The project is located in the reclamation area of Macau New Town, with a length of about 3.9 kilometers. According to the plan, a total length of 6.5 kilometers of common pipelines will be built under the main main road in Area A of Macao New Town, forming a circular layout around Area A of the New Town Reclamation Area, and laying public facilities including power supply, water pipes, reclaimed water pipes and communication networks in the underground common pipeline, so as to realize the intensive management and efficient laying of the underground pipe network.
1.Overview of waterproofing engineering
The common pipeline adopts a cast-in-place reinforced concrete rectangular frame structure, which is constructed by open cut method and has a fully enclosed waterproof design. Thermoplastic polyolefin (TPO) waterproofing membrane is used as the waterproofing layer for the waterproofing works of the underground pipe floor, exterior wall and roof.

3.Waterproof product selection
SGW820 TPO Pre-laid Waterproofing Membrane &; SGW840 TPO Self-Adhesive Waterproofing Membrane
5.Advantages of waterproofing membrane
SGW820 TPO pre-laid waterproofing membrane
- It has excellent properties such as high tensile strength, high elongation, impact resistance, tear resistance, chemical corrosion resistance, heat aging and dimensional stability;
- Excellent chemical corrosion resistance: resistant to acid, alkali, salt corrosion, algae, mold and other microbial growth;
- Good anti-bonding effect: the membrane forms a permanent bond with the post-cast concrete structure, and the settlement and deformation of the base layer do not affect its waterproof performance, and the reliability of the waterproof layer is improved.
SGW840 TPO self-adhesive waterproofing membrane
- Excellent chemical corrosion resistance: resistant to acid, alkali, salt corrosion, algae, mold and other microbial growth;
- Root puncture resistance: dense molecular structure and super seam strength, so that it has excellent physical root blocking ability;
- Hot air welding construction is adopted, and the lap sealing is highly reliable;
- Good construction performance: the cold adhesive method is used for construction with the base layer, and the construction speed is fast.
