In the form of profile iron pile tube combination retaining wall, the characteristics of steel strength is high, rigidity is big can be given full play to, with Reinforced concrete sheet pile wall phase specific strength is higher, constructs convenient, reduces the loaded down with trivial details of the maintenance of formwork during prefabrication Process.There is higher limit lateral capacity compared with steel sheet pile, processing and fabricating is convenient, and use range is more extensive.Work as wall Can be near stake top or stake top plus one grappling pull bar when high larger, can be with the length squeezed in soil and section of steel-pipe pile Greatly reduce.Horizontal support or skewed horizontal load structure can also be set, to ensure to combine the stability of retaining wall.In tenon groove structure Seam crossing waterproof sealing is carried out using high polymer grouting technology, can greatly improve combination retaining wall waterproof ability.Construction After the completion of by pile pulling operate, can to profile iron pile tube reclaim reuse.Can basis in actual Excavation Process Foundation ditch flat shape carries out combination in any, and range of application is quite varied.Therefore, profile iron pile tube combination retaining wall has good Stress performance and structural strength, convenient and quick construction, with good economic and social benefits.
The content of the invention
Building enclosure quick assembling, recoverable, factorial construction in order to solve the problems, such as base pit engineering, the present invention There is provided a kind of assembled profile iron pile tube combination retaining wall, it is possible to achieve the prefabricated construction of retaining wall structure.The combination gear soil Wall has good anti-native side bearing capacity and stiffness, and stability is strong, and water resistance is good, and scene does not have without any welding job amount yet There are the masterplate workload and concrete wet trade in prefabrication process, convenient and quick construction, and reuse can be reclaimed, it is economical Property is good.
Technical scheme is as follows:
. a kind of assembled profile iron pile tube combines retaining wall, it is characterised in that:Its retaining wall includes chapped pipe, connection End plate, high-strength bolt, steel pipe inner stuffing, high polymer.Using the end for being welded to connect end plate and steel tubes;Using high-strength spiral shell 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.
