Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention is carried out below further detailed
It describes in detail bright.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention, it is not limited to this hair
Bright range.
Unless otherwise defined, all technical terms and scientific terms used herein are led with technology of the invention is belonged to
The normally understood meaning of the technical staff in domain is identical, and term as used herein in the specification of the present invention is intended merely to retouch
State the purpose of specific embodiment, it is not intended that in the limitation present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of moisture-proof drainage facility of foundation pit civil construction, including steel plate box 1, the steel plate box 1
Lateral wall surrounding be provided with the channel steel 5 of insertion bottom of foundation ditch, the lower part of steel plate box 1 is provided with drain hole 2, and 2 outer wall of drain hole is set
There is steel tapping pipe 3, the port of the steel tapping pipe 3 is equipped with the steel screw thread nut cap 6 for sealing steel tapping pipe 3.Steel
Plate box 1 had not only been used as gear tidewater but also had doubled as gate storage compartment construction construction exterior sheathing, and steel plate box 1 is used as gear when reinforcing bar binding in foundation pit
Tidewater, steel plate box 1 is constructed exterior sheathing as gate storage compartment construction when supporting module.
As the improvement of embodiment, the channel steel 5 is vertically welded on the side wall of steel plate box 1.The outside of the steel plate box 1
Wall surrounding level is welded with channel steel cross beam 4, and the channel steel cross beam 4 is vertical with channel steel 5 fixed, is preferably led between the two using welding
It crosses channel steel cross beam 4 and increases integrally-built rigidity.
As the improvement of embodiment, the internal diameter and the outer diameter phase of steel tapping pipe 3 of the steel screw thread nut cap 6
Together, and the inner wall preprocessing of the steel screw thread nut cap 6 has a screw thread, and the outer wall of the steel tapping pipe 3, which is machined with, to match
Screw thread after steel screw thread nut cap 6 is tightened to steel tapping pipe 3, achievees the effect that seal tapping pipe 3.
As the improvement of embodiment, it is additionally provided with waterproof silk ribbon between the steel screw thread nut cap 6 and steel tapping pipe 3, it is close
It is good to seal effect.
As the improvement of embodiment, inclination angle is equipped between the steel tapping pipe 3 and horizontal plane.
As the improvement of embodiment, the interior space dimension of the steel plate box 1 is matched with the size of gate storeroom.
As the improvement of embodiment, the height of the steel plate box 1 matches with maximum outer tidal level head.
When construction, the maximum apparent size (length and width) of gate storeroom is first calculated, makes steel plate box 1 in conjunction with the size
Size (length and width) and process steel plate box 1 steel plate specification (this example takes 8mm thick steel plate), will be born further according to steel plate box 1
Maximum outer tidal level head and gate storeroom side wall concrete pour stress condition, calculate height (this example steel for determining steel plate box 1
The height of plate box takes the outer tidal level head+10cm of maximum), 5 type of channel steel of the insertion bottom of foundation ditch of 1 lateral wall surrounding of steel plate box setting
Number (this example takes No. 20 channel steels), spacing (this example takes 1.5-2m) and quantity (this example laterally, longitudinal unilateral takes 3,5 respectively).
The maximum tap water water that steel plate box 1 may fill is calculated, is required, is made in 1 side of steel plate box according to water discharge time
2 quantity of drain hole and size (this example takes 1 drain hole, aperture 20cm) of wall bottom, in conjunction with design requirement to steel plate box 1
Position measures setting-out, and on steel plate box basis, paving is filled out the fine aggregates such as rubble and flattened, and surface of base is towards 2 side of drain hole
To certain slope (this example takes 0.3%-0.5%) is stayed, so that 1 internal water accumulation of steel plate box is smoothly discharged；Channel steel 5 is squeezed into bottom of foundation ditch
Certain depth (0.5-1.0 times for generally squeezing into channel steel protruded length, this example take 0.5 times of channel steel protruded length), then will be pre- in advance
The steel plate box 1 of system is placed in position or on-site consolidation, and by steel plate box 1 and 5 firm welding of channel steel, while horizontal in outer side wall surrounding
If welding arterial highway channel steel cross beam 4 (this example takes together), and the steel tapping pipe 3 with preprocessing screw thread is welded at drain hole 2
It connects securely, stays certain inclination angle (this example takes 15 ° of inclination angles) downward, foregoing sequence operation is both needed to pursuing-tide operation (when low tide).By steel
After screw thread nut cap 6 processed is tightened to steel tapping pipe 3, gate storeroom civil construction can be carried out in steel plate box 1.
When occurring eagre in work progress, the frictional force to float, the self weight of steel plate box 1 and steel plate are resisted according to channel steel 5
Items weight in box 1 when judgement has obtained floating trend, tap water can be poured into steel plate box 1 and offsets buoyancy；It is moved back to tidewater
It goes, steel screw thread nut cap 6 is unscrewed and is removed, empty tap water through drain hole 2, steel tapping pipe 3, continue foundation pit inner gate
Storeroom civil construction.It repeats the above steps, until the following civil engineering project construction of highest water level terminates.
Moisture-proof drainage facility structure of the invention is simple, cost, at low cost, and steel plate box can not only keep off tidewater but also can store up as gate
Cell structure construction exterior sheathing is hidden, is had many advantages, such as economical, simple, practical.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
