The end plate for connecting lower two chapped pipes is tethered, long steel-pipe pile is constituted；Linked together by tenon groove structure between steel tubes,
Form cantilevered combination retaining wall；Gap between tenon groove structure passes through high polymer；Slip casting is carried out in water-proof sealing chapped pipe
Portion's soil stone is removed by excavated by manual work, and mixes the formation implant backfill such as rubble, waste concrete block；Chapped pipe can be with split shape
Into the flat shape for needing, the requirement of actual place excavation of foundation pit is met.
The present invention has following effective effect：
1. determine base pit engineering in building enclosure quick assembling, recoverable, the problem of factorial construction；
2. the characteristics of steel strength is high, rigidity is big can be given full play to, it is higher with reinforced concrete sheet pile wall phase specific strength,
Construction is convenient, reduces the complicated processes of formwork maintenance during prefabrication.
3. operated by pile pulling after the completion of constructing, profile iron pile tube can be reclaimed and be reused, economy is good.
4. high polymer grouting technique is adopted, and water resistance is good.
4. combination in any can be carried out according to foundation ditch flat shape in actual Excavation Process, be had wide range of applications.
The new prefabricated profile iron pile tube combination retaining wall intensity is high, and good waterproof performance, easy construction can be applied in building
In the building enclosure of base pit engineering, with more wide future in engineering applications.
