Wall here can be gentle excessive, edge reinforcement lapping and anchoring.
Preferably, the position of fixity is fixed together with the retaining wall.
Preferably, the retaining wall is made of armored concrete.
A kind of construction method of the retaining wall disengaged with body structure portion, the specific steps are that:
1) according to situation on the spot, the position of fixity of main structure is determined, to carrying out one-piece casting below position of fixity;
2) retaining wall is overlapped below position of fixity, retaining wall is inclined outwardly after 30 ° from position of fixity and is extended straight up,
The retaining wall and main structure for making position of fixity or more are detached from;
3) waterproof is done at the node at the top of retaining wall with main structure handover;
4) the outdoor backfill of position of fixity or more is backfilled.
Wherein, in the step 2), retaining wall part can be done after main structure gets rid of muscle, can also be with main structure one
With construction.
Waterproof is done in the step 3) method particularly includes: resilient rubbber cushion is installed at the node, and in elastic rubber
Construction sealing materials are poured around rubber mat, and after construction sealing materials solidification, rubber fastening band is wound around it.
Because the outdoor backfill of position of fixity or more cannot be backfilled before construction, in case retaining wall, which shifts to an earlier date stress, generates deformation, because
This, above-mentioned steps can not overturn.
Compared with prior art, the invention has the benefit that
(1) present invention disengages retaining wall more than position of fixity with main structure, while guaranteeing the rigidity of structure, is not required to
Shear wall is added, is conducive to save construction cost;
(2) calculation of the retaining wall designed by the present invention is identical with the calculation of common retaining wall, does not need
Additional calculating analysis, saves the time.
(3) retaining wall is received in position of fixity, it is not necessary to additionally do basis, and waterproof is easily wrapped, easy for construction, practicability is stronger.
