Face.
Preferably, the end face water string Xia Kou is concordant with catch pit bottom plate bottom surface, and spring fixed transverse rod is fixed on waterproof jacket
Away from 1/4 height and position of bottom in pipe.
Compared with the existing technology, the utility model has the following beneficial effects: passing through bullet in control hydraulic pressure apparatus for adjusting force
Basement floor launching stress is controlled and is being rationally designed in range by the mode of spring pulling force, and then is realized and reduced basement bottom board thickness
Degree, the purpose for reducing basement anti-floating pile quantity reduce basement civil engineering construction cost, accelerate the basement civil construction period；
Meanwhile basement bottom board protuberance, cracking, basement caused by capable of effectively avoiding the appearance of operation stage basement from transfiniting because of water pressure
The appearance of the burst accidents such as column inclination, cracking.
Detailed description of the invention
Fig. 1 is the floor map for basement bottom board launching stress adjustment structure；
Fig. 2 is the diagrammatic cross-section for basement bottom board launching stress adjustment structure；
In figure: 1, catch pit, 2, water string top cover, 3, water string, 4, nut, 5, spring, 6, spring fixed transverse rod,
7, fabric filtration layer, 8, rubble permeable structure layer, 9, screw rod.
Specific embodiment
As shown in Figure 1 and Figure 2, basement bottom board launching stress adjustment structure, comprising: catch pit 1, catch pit 1 are with one
Determine length and width, deep recessed concrete structure；Catch pit 1 has bottom plate, and rubble permeable structure layer 8 is arranged under 1 bottom plate of catch pit,
It is entire catch pit plane projection range that rubble permeable structure layer 8, which is laid with range, and rubble permeable structure layer 8 forms water-permeable passage；
Hydraulic pressure apparatus for adjusting force is set on 1 bottom plate of catch pit, room bottom plate launching stress is adjustably descended by hydraulic pressure apparatus for adjusting force.
Hydraulic pressure apparatus for adjusting force, comprising: water string 3, water string top cover 2, fabric filtration layer 7, spring 5, spring are solid
Determine cross bar 6, nut 4, screw rod 9；Water string 3 is vertically embedded in 1 base plate plane center of catch pit, the lower mouth of water string 3 in advance
End face is concordant with 1 bottom plate bottom surface of catch pit, and the end face suitable for reading of water string 3 is higher by catch pit backplate surface；Fabric filtration layer 7 is placed in
In water string 3, positioned at the bottom of water string 3, fabric filtration layer 7 prevents silt loss under basement bottom board, and spring is fixed
Cross bar 6 is fixed in water string away from 1/4 height and position of bottom, and 5 lower end of spring is connected to spring fixed transverse rod 6,5 upper end of spring
Connecting screw 9, screw rod 9 pass through water string top cover 2 connect with nut 4, water string top cover 2 pass through 5 pulling force of spring it is closely connected in
The end face suitable for reading of water string 3.
In hydraulic pressure apparatus for adjusting force nut adjust spring pre-stretched amount Δ, by spring rate K can obtain spring pretension P=
K·Δ.When basement bottom board launching stress F > P/A (A is water string basal area), the elongation of hydraulic pressure apparatus for adjusting force spring,
That is water string top cover is jacked up by ground water pressure.Therefore underground water at the top of water string by overflowing, hydraulic pressure under basement bottom board
Power can be adjusted to F≤P/A.
The utility model is further described below with reference to embodiment, but not as the foundation to the utility model.
Embodiment one.Certain double-deck basement, buries H=8.8m, conventional design anti-floating head h=8.3m, intends adjusting anti-floating water
Head h1=6.3m, hydraulic pressure reduce (8.3-6.3)/8.3=24%.
Basement bottom board launching stress adjustment structure, comprising the following steps:
A, permeable structure layer is set under basement water collection pit bottom plate, and techonosphere is made of 150mm thickness metalling.
B, the pre-buried hydraulic pressure apparatus for adjusting force of basement water collection pit bottom plate, hydraulic pressure apparatus for adjusting force is by water string, guard tube
Top cover, fabric filtration layer, spring, spring fixed transverse rod, nut and screw rod composition.Water string radius R=50mm, spring rate
COEFFICIENT K=25KN/m.
C, according to design anti-floating head h1 calculating basement bottom board launching stress, (γ is water capacity weight, takes 10KN/m3) F=
γ·h=10X6.3=63KPa。
D, hydraulic pressure apparatus for adjusting force spring pre-stretched amount Δ (mm) is calculated according to basement bottom board launching stress: water string
Cross-sectional area A=π R2=3.14X0.052=7.85X10-3m2, spring pretension P=FA=63X7.85X10-3=0.50KN, bullet
