Description
Technical field
The present invention relates to a kind of no pile foundation single layer underground garage anti-floating construction methods.
Background technology
Underground garage is an armored concrete babinet, is vulnerable to the work of underground water and rainwater or surface water in construction
With generation buoyancy mostly uses the anti-group of schemes such as stake or ground anchor pole, prevents and be deformed, float, tilting in the past;But effect
It is not very ideal.
Invention content
That the purpose of the present invention is to provide a kind of construction effects is good, reliably without pile foundation single layer underground garage anti-floating construction party
Method.
Technical solution of the invention is:
A kind of no pile foundation single layer underground garage anti-floating construction method, it is characterized in that:Include the following steps:
(1) seepage well construction, precipitation
It is non-sand concrete pipe, periphery 3-15mm that well casing, which preferably uses diameter 300mm pipe of concretes, pipe range 20m, filter pipe with material,
The filling of rubble coarse sand be used as filter layer, with clay backfilling and tamped within the scope of 0.5m from the ground;Cheng Jinghou tripping in 50T/h40m
The deep well submerged pump and drinking-water pipe of lift are discharged into drainage pipeline with Φ 75mm drainpipes, are discharged into city planting ductwork after precipitation;
Pipe well Cheng Jing uses high pressure water washing combination machine drilling well drilling technology, well head top 3.5m to be shut with clay;
Sandstone uses coarse sand, to prevent from blocking the mesh of chimney filter;
Filter pipe is placed on the centre of wellhole, and the thickness of sandstone filter layer is between 60-100mm, to improve water penetration, and
Prevent grogs from penetrating into the mesh of chimney filter;Back-up sand thickness is uniform, and mud is squeezed out wellhole, filler spade blanking, to prevent unevenness
The even or impact borehole wall, must not interrupt during back-up sand, cave in prevent hole wall;
The packed height of sandstone filter layer at least wants the above 1000-1800mm of hyperfiltration tube top, to ensure in soil layer flow
Under it is unimpeded;
Pipe well draws water 5-7 days, and precipitation water level starts to cut the earth after reaching foundation pit minimum point 0.5m or less;With digging depth
Increasing, deep-well pipe of concrete removes step by step, and well head is capped in shoveling, prevents soil from falling into well and blocking well casing;
(2) it cuts the earth
The earthwork, which divides two layers, is excavated, and about 2~3 meters of excavation depth of each step, the earthwork is directly excavated to base depth with digging machine
At above 300 ㎜, original soil is not stirred;The earthwork hand fit of 300 ㎜ of substrate carries out clear soil;The width of earth excavation, by basis
Additional 1.5 meters of the working face in bottom plate side, and calculate hole size suitable for reading by the slope gradient and put shoveling gray line;
Use reliable controlling measurement absolute altitude and digging depth during earth excavation, scene sets two spirit levels when construction
Carry out tracking measurement;And according to the bracing wire inspection at any time of sight rail absolute altitude;
Side slope, which is repaired, uses manual amendment, according to mouth line above and below slot, draws and leads to line, the part of protrusion is rejected with iron pick, then is used
Spade is evened out;Foundation pit periphery side slope matches two-way Φ 6 200 or Φ 1.5mm steel wire bank protections using 60mm thickness pea gravel concretens, point
Side slope presses 1 between block:1.5 slopes are covered using colour bar cloth;
After the completion of earth excavation, before pouring bed course, according to seepage well position, is arranged between seepage well and buries Φ 50mm bellowss,
Electric wire is worn after base plate of foundation pit concrete construction, is used for seepage well precipitation pump power;
(3) basement bottom board construction, basement structure construction, waterproof construction, protective layer construction are carried out;
(4) backfill loads
Foundation pit backfill uses silty clay, compacting factor >=0.94;
Back fill course THICKNESS CALCULATION:
When basement structure construction is completed, by the calculating of level of ground water limes superiors, buoyancy is suffered by underground garage:By 1 square
Rice calculates
FIt is floating=H* γWater
F in formulaIt is floating--- buoyancy
H --- underground garage is immersed in water level or less height
γWater--- the proportion of water
Basement structure is conducted oneself with dignity:
G=(h1+h2) * γConcrete
G in formula --- underground garage is conducted oneself with dignity
H1 --- underground garage basis converting thickness
H2 --- top plate of underground parking garage converting thickness
γReinforced concrete--- the proportion of armored concrete
Ensure that basement because buoyancy force of underground water floats, does not backfill soil thickness:
The favorable factors such as adsorption capacity and the frictional force between basement and the earthwork are not considered, take safety coefficient k=1.15
H=k (FIt is floating-G)/γSoil
K in formula --- safety coefficient
FIt is floating--- buoyancy
G --- underground garage is conducted oneself with dignity
γSoil--- native proportion;
(5) deformation, sedimentation observation
Measure content;The horizontal displacement monitoring of excavation slope, the settlement observation of excavation slope, the sedimentation for closing on building are seen
It surveys, sedimentation observation in underground garage structure work progress;
The arrangement of measurement point;Along about 1.50 meters of foundation pit week back gauge foundation pit side, monitoring point is arranged every 15 meters of spacing;It can be used
Pre-buried precast concrete block of cutting the earth is arranged;The settlement observation of building is measured using the settlement observation point on main building, and underground garage exists
Point of observation net is arranged on structural column;
Vertical sedimentation is observed, the point on the basis of level reference point or permanent benchmark;Closed circuit monitors, and observed range is not
More than 30 meters, observation front-and rear-view highness change is within 30cm;
Excavation slope horizontal displacement monitoring;The point done on above-mentioned foundation pit periphery, as leveling observation point, are also foundation pit sides
The horizontal displacement monitoring point on slope;
(6) planting technique.
It deforms, the monitoring, alarming value of sedimentation observation:
Continuous 2 days foundation pit horizontal displacement of slope≤35 ㎜, 3 ㎜/d;
The ㎜ of excavation slope vertical sedimentation≤30;
Building deformation monitoring, alarming value;The adjacent settling amount alarming value of building determines that building foundation inclines according to design
Oblique alarming value is 3 ‰.
The porosity of filter pipe is 20%-25%, and suction hose sinks to pipe well pumping using caliber 100mm glue modeling pipe, lower end
Below lowest water level when suction.
Construction effect of the present invention is good, reliable;
Construction investment is reduced, engineering pile foundation will generally account for 5 the percent of project cost, and cancellation pile foundation, which has also subtracted, holds
Platform more reduces project cost.
It is easy for construction, eliminate pile foundation, sole plate eliminates piling without cushion cap, the processes such as broken pile head, construction bearing platform,
Foundation slab structure is simple, and facility is brought to construction.
It shortens the construction period, than the conventionally employed anti-engineering for dialling stake, not beat test pile, beat the works such as engineering pile, detection, construction bearing platform
Make, largely shortens the construction period.
On underground garage structure after backfill, greening lawn is planted, graceful construction environment to green construction, is accomplished " four
One environmental protection of section " has realistic meaning.
With reference to embodiment, the invention will be further described.
