Specific embodiment
One kind as shown in Figure 1, Figure 2, Figure 3 and Figure 4 reclines formula steel boxed cofferdam, including what is be connected with existing structure object 1
Steel bushing box body 2 is provided with piecing devices 3 between existing structure object 1 and steel bushing box body 2, piecing devices 3 include and steel jacket box
The connection guider 4 that babinet 2 is fixedly connected and the board plug device 5 moved in connection guider 4；Board plug device 5 is filled
It connects the gap between guider 4 and existing structure object 1 and forms reperfusion space.
Connection guider 4 includes the connecting substrate 41 being connected with steel bushing box body 2, be arranged in connecting substrate 41 two
Guide rail structure 42 and junction steel plate 43.Each guide rail structure 42 has two panels steel plate, to be in the interior steel in reperfusion space
Plate and the outer steel plate being in outside reperfusion space are connected by fixed structure between the interior steel plate in two guide rail structures 42.Connection
Steel plate 43 includes connecting substrate 41 and steel bushing box body 2 strengthening the first junction steel plate being connected and by connecting substrate 41 and guide rail
Structure 42 strengthens the second junction steel plate of connection.It is led by fixed structure and being equipped with so that entirely connecting for junction steel plate 43
It is enough the filling for supporting concrete to the structural strength of device 4.
Above-mentioned connection guider 4 and steel bushing box body 2, and the welding method between its internal various pieces is：
Step 1：Process the welding surface of steel plate so that welding surface is in a gradient face；Angle [alpha] between two grooves is
60°。
Step 2：The welding surface bottom of steel plate mutually props up；
Step 3：Installed at the both ends of the soldered of two blocks of steel plates draw, arc-extinguishing plate；
Step 4：By steel plate weld preheating, steel plate weld preheating temperature is 100~130 °, and automatic with narrow gap submerged arc
