Structure 113, the portion being exposed to by the anchoring sealing of concrete structure 113 punching block 21 for backfilling the soil body or pouring outside float Structure 24
Point.The actual range of foundation ditch 11 encloses the scope formed by brick fetal membrane 112, but outwards can be dug out when foundation ditch 11 excavates more
Segment space so that certain gap, frame structure 20 are left between the inwall of the foundation ditch after excavation and the brick fetal membrane 112 of setting
Upper anchorage in the backfill soil body or concrete structure 113 of the gap location.Backfilling the soil body can use graded sand and stone to be layered
Tamp, concrete structure 113 can pour to be formed using low-grade concrete.Poured in the periphery suitable for reading of foundation ditch 11 formed with a knot
Structure layer 114, the structure sheaf 114 is on the backfill soil body or concrete structure 113.
Sealing punching block 21 of the present utility model connects reinforcing plate 22 and seal plate 23 using frame structure 20 is first spliced into
Afterwards, overall hang in is backbreak in space together, is fixed with suspension ring 25 in four corner portions of frame structure 20, can be passed through suspension ring 25
Frame structure 20 is lifted into and backbreak in space, frame structure 20 has preferable stability, and its own can stably be erected
In space of backbreaking, in order to prevent frame structure 20 from being deformed during hanging, before lifting, face inside frame structure 20
When support cross support structure or groined type supporting construction.Setting-out is first carried out before hanging, ensures to lay accurately, utilizes automobile
Lift the frame structure 20.
It is to reduce SEA LEVEL VARIATION to being molded coagulation in tide moves water when pouring self-compacting concrete formation float Structure 24
The influence of soil property amount, time of the self-compacting concrete poured preferably select climax after the ebb time.The self-compacting concrete
Pour and use underwater casting method, ensure the continuous placing of concrete using automobile concrete pump, in casting process, it is necessary to protect
Card concrete pump pipe end port is embedded in concrete, must not be extracted from the surface of concrete.During to reduce bottom of foundation ditch because excavating
The influence of caused mud, self-compacting concrete pours to be poured since one jiao of the space of backbreaking of foundation ditch, utilizes concrete dense
Degree the characteristics of being more than water and mud density, mud is rushed to behind another angle in space of backbreaking and float on the top of concrete, poured
Exposed sealing punching block is gently tapped into rear, ensures sealing punching block, reinforcing plate and the seal plate and self-compaction of bottom
Concrete is combined closely, and reaches water-stagnating effect, and the top surface absolute altitude of the float Structure 24 must not exceed the bottom absolute altitude of bed course 111, if
Exceed, then will exceed part and pick chisel.After float Structure 24 reaches intensity requirement, i.e., the intensity of float Structure 24 is more than buoyancy pair
Caused by lower concrete during pressure, the ponding in sealing punching block 21 is discharged, and mud is cleaned out.Then in anti-floating knot
Unwrapping wire determines the construction location and construction cushion coat 111 of bed course 111 on structure 24.
The utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can root
Many variations example is made to the utility model according to described above.Thus, some details in embodiment should not be formed to this practicality
New restriction, the utility model will be used as the scope of protection of the utility model using the scope that appended claims define.
