Description
Technical field
The present invention relates to a kind of steel sand bucket, more specifically to one kind is applied to show bearing capacity in real time in bridge rotating
Steel sand barrel, belong to technical field of bridge construction.
Background technology
In recent years, with high-speed railway, the construction of highway, large quantities of leap existing railways and highway are emerged in succession
Large bridge.Such large bridge due to being restricted by construction environment and traffic factor, using conventional construction method difficulty very
Greatly, influence of the erection by swing construction can preferably avoid transporting All other routes is usually taken.
At present, swivel, the core during swivel are generally realized using the method for flat turn in the construction of bridge rotating method
Part is Rotary ball hinge；Rotary ball hinge is typically mounted at the theoretical position of centre of gravity of swivel bridge, and it is mainly by ball pivot main part, auxiliary
Support system and trailer system three parts are helped to constitute.Swivel bridge during construction, due to construction error, its reality
Center of gravity can not possibly be always held at the center of Rotary ball hinge；The deviation of center of gravity can produce tilting moment, the work of auxiliary shoring system
With being to carry the scope inner equilibrium tilting moment at it, it is ensured that the smooth construction of bridge.
Steel sand bucket belongs to the part in auxiliary shoring system, undertakes whole together with ball pivot main part when bridge is poured
The weight of bridge.But steel sand bucket is temporary support, bridge can be weighed and counterweight before swivel after the completion of pouring to the bridge,
Now steel sand bucket will be removed；By weighing and counterweight for bridge so that the actual center gravity of bridge is at Rotary ball hinge center
In certain deviation range, meet swivel and require.
At present, existing steel sand bucket, the function with vertical one-way movement simultaneously can bear certain vertical load, but can not
Show the size of its vertical load born so that bridge its center of gravity deflection during pouring is unable to real-time monitoring, finally
Bridge pours and completes its position of centre of gravity and may farther out, before swivel be unfavorable for the stabilization of whole bridge from theoretical position of centre of gravity deviation
Property.
The content of the invention
It is vertical that steel sand bucket it is an object of the invention to be directed in the construction of existing highway bridge erection by swing can not show that it bears
The size of load so that bridge is the problems such as its center of gravity deflection is unable to real-time monitoring during pouring, there is provided one kind is applied to
The steel sand barrel of bearing capacity is shown in bridge rotating in real time.
To achieve the above object, institute is the present invention using technical solution：One kind is applied to show in real time in bridge rotating
Show the steel sand barrel of bearing capacity, it is characterised in that：Including steel sand bucket and data synthetical collection instrument, described steel sand bucket includes upper
Sand bucket, lower sand barrel and cover plate, the upper sand barrel are be made up of upper sand barrel panel, upper sand barrel base plate and upper sand barrel wallboard barrel-shaped
Concrete is filled with body, upper sand barrel, the lower sand barrel is made up of lower sand barrel panel, lower sand barrel wallboard and lower sand barrel base plate
Barrel-shaped body, two lower sand barrel flange connecting plates are provided with lower sand barrel along bucket wall circumferencial direction, and lower sand barrel is under-filled quartz
Sand, described lower sand barrel wallboard outer surface is provided with hanger, and the staving of upper sand barrel is placed on the quartz sand of lower sand barrel, described
It is connected by screw bolt and nut between upper sand barrel panel and lower sand barrel panel, described cover plate is arranged on by screw and packing ring
On lower sand barrel wallboard, built-in type concrete strain gauge is installed in described upper sand barrel, along bucket wall between upper sand barrel and lower sand barrel
It is circumferential that four guy type displacement meters are uniformly installed, described built-in type concrete strain gauge and guy type displacement meter respectively with number
It is connected according to synthetical collection instrument.
Upper sand barrel shrouding is provided with described upper sand barrel panel.
Described upper sand barrel is internally provided with upper sand barrel gusset.
Described lower sand barrel inner bottom surface is evenly distributed four pressure cells, described pressure cell and aggregation of data Acquisition Instrument phase
Connection.
Described lower sand barrel wallboard outer surface is evenly distributed and is provided with four external labeling type strain gauges, and described external labeling type should
Become meter to be connected with aggregation of data Acquisition Instrument.
Compared with prior art, the beneficial effects of the invention are as follows：
Built-in type concrete strain gauge is installed in the present invention in upper sand barrel, installation is evenly distributed between upper sand barrel and lower sand barrel
There are four guy type displacement meters, lower sand barrel inner bottom surface is evenly distributed four pressure cells, and lower sand barrel wallboard outer surface is circumferentially equal
Cloth is provided with four external labeling type strain gauges, and the strain of built-in type concrete strain gauge, guy type displacement meter, pressure cell and external labeling type
Meter is connected with aggregation of data Acquisition Instrument respectively.Therefore the size of its bearing capacity can be in real time shown in bridge casting process,
So that bridge can pour density in casting process according to the pressure value real-time control of each steel sand bucket, it is ensured that center of gravity is being wanted
In the range of asking, solving existing steel sand bucket can not in real time show bearing capacity, cause bridge to pour completion its position of centre of gravity possibility
From theoretical position of centre of gravity deviation farther out the problems such as, it is ensured that position of centre of gravity in error range, improve bridge construction process in it is steady
It is qualitative.
