Description
Technical field
The present invention relates to a kind of bridge construction with rack device and method is fallen, belong to construction equipment field.
Background technology
With flourishing for China's economy, bridge construction enters all-round developing stage, the construction method of science of bridge building
Also step must be closely followed.
At present in bridge construction, the rack device that falls of cast-in-situ box girder falsework uses flask device more, i.e., justifies in steel
Built-in back-up sand of cylindricality sand cylinder, provides bearing capacity, construction finishes, and opens the valve on sand cylinder by sand cylinder for wrapping for sand
Door, sand outflow pore, bearing capacity disappear, that is, complete frame.The device and method is primarily present following several shortcomings：（1）Sand
Cylinder position is normally near pier coping portion, and height is higher, and each dropping for sand cylinder is both needed to special messenger by specially setting up
Scaffold turn on the valve of sand cylinder one by one to realize, it is especially time-consuming and laborious for high pier.（2）Multiple stents of same bridge or
Dropping for multiple sand cylinders of same stent is difficult synchronous progress, and bridge and stent easily produce uneven stress, and it is hidden to there is safety
Suffer from.
Therefore, design it is a kind of easy to operate and easy to the bridge construction that synchronously drops with falling rack device and fall frame side accordingly
Method, is those skilled in the art's urgent problem to be solved.
The content of the invention
To solve the problems, such as inconvenient existing for prior art decline rack device and being difficult to synchronously drop, the present invention provides
A kind of new bridge construction is with falling rack device and fall frame method, using following technical proposals：
A kind of bridge construction is with falling rack device, it is characterised in that including：Outer barrel, inner cylinder, filler, water inlet pipe, outlet pipe, PVC are soft
Pipe, high-pressure hydraulic pump, Sewage treatment case；
Wherein, outer barrel includes outer barrel barrel and outer tube end plate, and filtration apparatus, the filtration apparatus bag are equipped with the outer barrel barrel
Include the isolation board with distribution hole in cylinder, be filled in the cast steel ball and water inlet pipe in space between isolation board and outer barrel barrel
Outer barrel barrel distribution hole corresponding with outlet pipe；
The filler is arranged in outer barrel, is divided into 2 layers, and lower floor's filler is sand, and upper strata filler is at least partially NaCl crystal
Solid packing；
Inner cylinder is arranged in outer barrel opening, above filler；
PVC hose connects high-pressure hydraulic pump and water inlet pipe, Sewage treatment case and outlet pipe respectively.
Preferably, the inner cylinder includes top plate, interior tube end plate, inner cylinder barrel, stiffener, fill concrete, wherein supporting
The ceiling edge of stent exceeds outer barrel barrel.
Or it is preferable, lower floor's packed height exceedes filtration apparatus, and particle diameter is 1.25mm ~ 2.5mm；The isolation board point
The diameter of cloth hole is less than lower floor's packing material size.
Or it is preferable, the upper strata filler is sand and NaCl crystal admixtures, the weight accounting of NaCl crystal for 40% ~
70%。
Or preferable, all NaCl crystal of upper strata filler.
It is a kind of to fall frame method with fall rack device using any of the above-described bridge construction, it is characterised in that to include the following steps：
Step 1：Before bridge pouring construction, the outer barrel is placed on supporter, fills filler as needed, inner cylinder is put into outer
Cylinder, stent is placed on inner cylinder top plate, then connects PVC hose on water inlet pipe, outlet pipe respectively；
Step 2：After hardening is completed in cast-in-situ bridge construction, water inlet pipe is connected into PVC hose connection high-pressure hydraulic pump, outlet pipe is connected
PVC hose connects Sewage treatment case；
Step 3：High-pressure hydraulic pump is opened, hydraulic pressure is entered into outer barrel, enters Sewage treatment case through outlet pipe；
Step 4：With the dissolving and discharge of upper strata filler, under the effect of the pressure, filler can gradually reduce, and inner cylinder gradually drops
It is low, realize frame.
The present invention has the following advantages that：
（1）Packing volume is set steadily to reduce by way of dissolving, discharging, so that stent steadily declines；
（2）Supplied water with high-pressure hydraulic pump by PVC hose into outer barrel, can not only avoid manually specially setting up foot hand in the prior art
Frame operate sandbox inconvenience, can also Multi-path synchronous carry out, it is ensured that stent integrally falls the steady of frame, makes bridge and support force equal
It is even.
