Bed board composition；
Step is 5.: it is 4. described according to step, it installs on hydraulic jack to the lower beam of open type hoisting frame, hydraulic control panel peace
It is filled on bed board and is connect with oil piping system and water, electric corollary system；Hydraulic control panel controls high-voltage oil liquid and passes through oil fuel tube, divides
Oil pipe and branch oil pipe are transported in each hydraulic jack, hydraulic jack lifting motion；The first layer concrete is poured to internal model
Between plate and former borehole wall supporting surface, concrete casting height is once 30-40cm, with a thickness of 40-80cm, is poured second layer coagulation
Soil is about 2 hours with the first layer concrete interval, continuous alternately with 2 hours for a duration, until reaching required deep-well
Structure height；
Step is 6.: 5. described according to step, hydraulic jack elevator belt moving template is sliding by track of support rod；One layer of casting mixed
The solidifying soil sliding 30-40cm of rear pattern plate, continuous was alternately a duration climbing form 30-40cm until reaching required depth with 2 hours
The structure height of well；It can be applied to that it is more, the wasting of resources to avoid equipment in traditional slding form operation in deep-well garage borehole wall building
Problem, the deep-well passage construction speed for being becomes faster, save formwork and tower sets labor and materials required for scaffold, saves disposable investment
The dosage of template more can be dismantled easily and flexible assembling and be may be reused.
Consider the stability of support rod and the stability of whole operation platform, at least 24 hydraulic jacks are set altogether along barrel
Top, support rod are with 48 × 3.5 steel pipe of Ф, inner template 900 × 200.Main operation platform is set as space truss form, platform bed board
30~50 thickness about 135m2, weight about 9.0t of thickness；Support rod permitted bearing capacity calculates:
Wherein: the permitted bearing capacity of P- support rod；A- service factor, takes 0.7；E- support rod elasticity modulus, E=
2.06×10^5/mm2；J- support rod cross sectional moment of inertia, J=12.16cm4；K- safety coefficient, takes 3.0；LO- support rod
It comes to nothing length, takes 1.2m；Therefore: consider engineering practice, there are certain bearing capacity leeway, support rod bearing capacity presses 3.0t
It chooses.
Sliding form apparatus design load calculates as follows:
1, the self weight of template system, operation platform system: consider by 9t；
2, the construction loads on main operation platform: 135 ㎡ × 100kg/m^2=13.5t；Frictional resistance when 4 templates are promoted: because
It is steel form, frictional resistance takes 3kN/m^2.
The kN/m^2=21t of 70 ㎡ × 3；1.2 N=43.5 × 1.2 of 9+13.5+21=43.5t load factor=52.2t n=N/P
=52.2/3=17 platform, less than selected 24；Therefore: support rod is fully able to meet the promotion requirement of main operation platform.Support
The calculating of bar:
Hydraulic jack is climbed with support rod using 48 × 3.5 steel pipe of φ；Load P=N1/n=169.1/84 that every bar is born=
20.13KN。
The allowable load of support rod calculates, formula [P]=0.7 × 40EI/K (L0+95) 2；In formula: support rod in E-formula
Elasticity modulus=2.1 × 104KN/cm^2.
I-support rod cross sectional moment of inertia=12.296cm4；K-safety coefficient=2.
L0-support rod drift, by least favorable state computation when being promoted.
The high 120cm of template, template is suitable for reading to arrive the high 50cm of mouth under hoisting frame crossbeam, under hoisting frame lower beam under mouth to jack
Bayonet distance 25cm, bottom plate is thick temporarily to take 1.0M；L0=120+50+25+100=295cm.
Substitute into data: [P]=0.7 × 40 × 2.1 × 104 × 12.296/ { 2 × (295+95) ^2 }=23.7 > 20.13KN
(safety).
Step 6. in, deep-well channel reaches the structure height of required deep-well, continues empty sliding template 50-60cm height until high
Ground level out, form removal system, operation platform system, hydraulic lifting system.
Step 2. in, template is fixed form combined steel mould, and concrete sizing, casting effect are good, is not easy to leak outside.
Step 3. in, enclosure and open type hoisting frame weld；Structural strength is high, convenient when dismantling after the completion of construction.
Step 2. in, open type hoisting frame pillar construction using steel pipe make, hydraulic jack promoted when, promoted by open type
It is sliding upwards that frame drives enclosure, template and operation platform system to synchronize, and will be sliding when the vertical load that generates be transmitted to liquid
It presses on jack and support rod.
Step 3. with step 4. in, main operation platform for wiretie, casting concrete, template sliding lifting control, main behaviour
Make platform to tile using thick steel plate；Auxiliary operation platform disk thick steel plate Mi Pu, disk width are 70-80cm, and major-minor
Operating platform is equipped with anti-fall be caught；Preventing dropped material, structural strength is high, stationarity is good, and disk must be tight, prevents from collapsing, fall apart, and pacifies
Full operation.
Step 5. in, borehole wall internal layer surface, which is added, buries water-stopping steel between waterproof filler and the concrete of second pouring
Band, since deep-well channel is under, ponding is easily infiltrated on the outside of the borehole wall, and addition waterproof filler avoids infiltration inside the borehole wall,
It can be the pond special-purpose water-proof anticorrosive paint layer of model PHA103, PHA105.
Step 6. in, high-voltage oil liquid is delivered in hydraulic jack, and continuous oil supply oil return makes the piston of hydraulic jack
It constantly compressed, resetted, being withstood on by hydraulic jack sliding on support rod keeps template sliding upwards；Template sliding lifting verticality is by swashing
Light oriented control, for control casting after concrete verticality.
Step 6. in, support rod is rigid material, and using bushing type support rod, internal diameter is added on the outside of support rod greater than its 2-
The casing of 5cm, sleeve upper end are fixed with open type hoisting frame crossbeam, and lower end is connect with template；And support rod also can be used
Joggle, snapping.
Make the preferred embodiment of the present invention above, does not depart from original of the invention for those of ordinary skill in the art
Under the premise of reason, several variations and modifications can also be made, these also should be regarded as protection scope of the present invention.
