Apply the Shui Pingliang (140) of initial flexing exactly.

Further, the top ad-hoc location of high strength I beam (230) is fixedly installed prestressing force and leads steel wire (295).When this uses prestressed wale, certain distance to be had with cladding plate breast boards position with by the structure of setting, the effect of ability useful prestressing steel (170) Shi Hanzhang.

Under there is no the ground condition of spacing between the structure of breast boards and setting, also likely produce the situation can not using prestressing steel (170) Shi Hanzhang.

So need the waist rail reducing Shi Hanzhang waist rail height with prestressing steel.

So the 4th case study on implementation is the scheme that significantly can reduce waist rail.

As shown in Figure 22 to Figure 25, the cladding plate that the present invention can import additional counter-force is made up of simple light weight prestressing steel fixed support (290), Shui Pingliang (140), prestressing steel with prestressed wale temporarily.Above-mentioned simple light weight prestressing steel fixed support (290) be by prestressing steel fixed part (294), gripper shoe (293), pressing plate (292) formed, the upper bonding high strength I beam (230) of above-mentioned water Ping Liang (140), form the initial flexing water Ping Liang of the opposite direction Shi Hanzhang toward service load, and be made up of prestressing steel and prestressing steel gland.

At this, after above-mentioned simple light weight prestressing steel fixed support (290), Shui Pingliang (140), prestressing steel are assembled into one, the spacing of bearing can be expanded to 10 ~ 15m, reduce bearing more than 50% than traditional construction method.

And, the prestressing force bottom girder light weight waist depth of beam importing additional counter-force of the initial Buckling Loads of above-mentioned importing is at about 1m, can minimize cladding plate retaining wall and by arrange structure between distance, land utilization ratio is improved in down town, and the weight of waist rail also gentlier can be widened to 6 ~ 16m the distance between bearing (130), is the waist rail that an efficiency is high.

Further, because the opposite direction of the service load with water Ping Liang (140) imports initial Buckling Loads, so very stronger than its rigidity of waist depth of beam.

And in geotechnique's construction, when the waist rail of soil pressure conjugates large overleaf, also simply can continue Shi Hanzhang with simple light weight prestressing steel support (290), reduce waist rail manufacturing cost than first, second and third case study on implementation.

Also have when producing becoming of waist rail according to the change of soil pressure in construction, also can add at prestressing steel (170) timely and import prestressing force, can the innovative waist rail of safe construction.
