(7) it is fixed with main cross bar (3), secondary cross bar (4) and brace (16), brace (16) is supported on ground by triangle backing plate (5), is stood
Bar (2) is supported on ground by horizontal backing plate (6), and wall connecting rod (17) is embedded on Gravity Retaining Wall (1) and is connected with wall is buried
The channel steel reinforcer (18) of extension bar (17) connection, steel pipe scaffold support and bury wall connecting rod (17) and be connected and fixed to laterally solid
Due on Gravity Retaining Wall (1), big brace (34) be fixed on multiple main cross bars (3) and multiple upright bars (2) it is same in a straight line
Tie point on, increase stable degree；
The builder's jack support includes the main cross bar of overhanging (11) and multiple overhanging bars being fixed on Gravity Retaining Wall (1)
(9), builder's jack support include also with multiple overhanging upright bars for overhanging main cross bar (11) and multiple overhangings bar (9) and fixing
(10), overhanging brace (12) is connected between two neighboring overhanging upright bar (10), Gravity Retaining Wall is embedded with multiple drainings on (1)
It manages (8), multiple overhanging bars (9) are each passed through corresponding drainpipe (8) and are connected and fixed with steel pipe scaffold support, builder's jack
Support is up set up as Gravity Retaining Wall (1) is up built, and the synchronous builder's jack support for removing lower end；
In the step 5) in Gravity Retaining Wall (1) mortar flag stone work progress, embedded drainpipe (8) and wall connecting rod is buried
(17), channel steel reinforcer (18), and a certain range package cement mortar is constructed around it with facilitating, the Gravity Retaining Wall
(1) synchronous construction concrete intensive aspect (33) on the outside；
The formwork erection structure of the step 6) includes the concrete rib band (19) that Gravity Retaining Wall (1) is equipped with, concrete rib
Band (19) both ends are respectively and fixedly provided with a set shaped steel formwork (21), and Gravity Retaining Wall (1) two sides are embedded with a concrete embedded body respectively
(24), two concrete embedded bodies (24) are connected with a channel steel sliding slot (27), and two set shaped steel formworks (21) are ipsilateral with it respectively
Channel steel sliding slot (27) slidably connect, two set shaped steel formworks (21) by a form spreader (20) respectively with steel pipe feet
Hand cradle support and builder's jack support are connected and fixed, and horizontal ribs (22) and vertical rib are fixed on set shaped steel formwork (21)
(23)。
