Abstract
The utility model belongs to the technical field that swivel bridges rotor system is installed, be specifically related to a kind of construction equipment for pouring into sand proportioning and closed water proof in the interim sandbox of swivel bridges, when solving existing swivel bridges rotor system installation, the situation of swivel bridges stress system conversion can not be completed in time, and then the problem causing construction delay and rotor system to damage.It comprises sandbox inner sleeve setting up and down and sandbox overcoat, sandbox inner sleeve bottom is set within sandbox overcoat, clearance aperture between the inside and outside cover of sandbox makees oil sealing by 1# lithium saponify, between sandbox inner sleeve outer bottom and sandbox overcoat inner bottom part, quartz sand packed layer is set, sandbox jacket bottom arranged outside draws sand mouth, draws sand mouth and makes oil sealing by 1# lithium saponify and carry out shutoff by sand block plate.The utility model reduces that interim sandbox sedimentation is uneven easily hardens and the impact of difficulty on swivel bridges construction removed by sandbox, the stable of steel structure of turning when ensure that the operation duration of swivel bridges and turn.
Description
Technical field
The utility model belongs to across the technical field of building swivel bridges for temporary support system, is specifically related to a kind of construction equipment for pouring into sand proportioning and closed water proof in the interim sandbox of swivel bridges.
Background technology
In swivel bridges construction, due to superstructure and substructure construction longer for interval time, ball pivot need enter stressed for a long time, affect the stable of Rotary ball hinge and slideway, therefore need to arrange interim sandbox to support, but in interim sandbox, the control stress point that waterproof is interim sandbox installation quality closed by perfusion sand proportioning and sandbox.It is an incremental process that swivel bridges is turned stressed, and along with the construction of superstructure, rotor system is stressed gradually.In time being subject to unbalanced load, ball pivot and spike will be subject to the effect of unbalanced load, and off normal occurs, larger on subsequent handling impact.After installing interim sandbox, when Superstructure Construction, load carries out transmission load by interim sandbox, is evenly distributed on by load in substructure, reduces the uneven stressed of ball pivot and spike.Therefore sandbox is the main member of stress transmission in swivel bridges work progress.But in practical operation, because sandbox is in stress transmission process, sandbox is stressed gradually, and in sandbox, sand is closely knit gradually, then in work progress under the natural conditions effect such as rainwater, in sandbox, sand hardens, difficulty when causing removing.Affect the operations such as swivel bridges is weighed, rotation, during dismounting, slideway is damaged, affect the rotation of spike, increase the mill resistance coefficient that slides, produce instability condition, potential safety hazard is formed to bridge line during rotation.
Summary of the invention
Problem to be solved in the utility model: existing sandbox does not have standard to fill with sand requirement, constructor can only carry out filling with sand proportioning in adjustment sandbox according to on-the-spot practice of construction condition, in case of in sandbox, sand makes moist, pour in down a chimney after water, sand hardens shaping, cause sandbox to remove difficulty, damage larger to slideway when abolishing sandbox.
The utility model adopts following technical scheme to realize:
For pouring into the construction equipment of sand proportioning and closed water proof in the interim sandbox of swivel bridges, comprise sandbox inner sleeve setting up and down and sandbox overcoat, sandbox inner sleeve bottom is set within sandbox overcoat, clearance aperture between the inside and outside cover of sandbox makees oil sealing by 1# lithium saponify, between sandbox inner sleeve outer bottom and sandbox overcoat inner bottom part, quartz sand packed layer is set, sandbox jacket bottom arranged outside draws sand mouth, draws sand mouth and makes oil sealing by 1# lithium saponify and carry out shutoff by sand block plate.
When swivel bridges upper load increases gradually; the utility model can prevent from causing because sandbox sedimentation is excessive; in sandbox sand harden remove difficulty; simultaneously because the rational proportion of sand causes sand space little; settlement stability; can play a protective role to ball pivot, ensure that the safety and stability of core system of turning.Damage slideway when superstructure can prevent from removing interim sandbox after completing again, what ensure when structure is turned is stable, reliable.
The utility model hinge structure has following beneficial effect: when swivel bridges rotator construction, superstructure load can be delivered to substructure by the utility model uniformly, reduce differential settlement to sand in the infringement of rotor system (ball pivot) and sandbox harden remove time infringement to slideway of turning, by application of the present utility model, reduce interim sandbox sedimentation uneven easily harden and sandbox remove difficulty on swivel bridges construction impact, reduce the impact of natural calamity on interim sandbox, to turn when ensure that the operation duration of swivel bridges and turn the stable of steel structure.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model,
Fig. 2 is the a-a sectional view of Fig. 1,
In figure: 1-sandbox inner sleeve, 2-quartz sand packed layer, 3-sandbox overcoat, 4-1# lithium saponify oil sealing, 5-sandbox base, 6-sand block sheet, 7-draws sand mouth.
Detailed description of the invention
By reference to the accompanying drawings detailed description of the invention of the present utility model is described further.
For pouring into the construction equipment of sand proportioning and closed water proof in the interim sandbox of swivel bridges, comprise sandbox inner sleeve 1 setting up and down and sandbox overcoat 3, sandbox inner sleeve 1 bottom is set within sandbox overcoat 3, clearance aperture between the inside and outside cover of sandbox makees oil sealing by 1# lithium saponify, between sandbox inner sleeve outer bottom and sandbox overcoat inner bottom part, quartz sand packed layer 2 is set, sandbox overcoat 3 bottom outside arranges and draws sand mouth 7, draws sand mouth 7 and makes oil sealing by 1# lithium saponify and carry out shutoff by sand block plate 9.
Quartz sand packed layer is the compound that 3mm and 5mm quartz sand mixes according to 1:1, and sectional dimension is determined according to rotor system middle slideway size.The utility model bottom is placed in turns on slideway, and top is connected with upper cushion cap of turning.The quartz sand compound of 2cm laid by sandbox between sandbox base 8 and slideway before installing.Generally, the distance of slideway and upper cushion cap is greater than the utility model height 30cm, the compound adjustment that this discrepancy in elevation mixes according to 1:1 by pouring into 3mm and 5mm quartz sand in sandbox overcoat.Swivel bridges top construction period, sandbox is placed in foundation ditch for a long time, and in sandbox, quartz sand easily makes moist and hardens, and therefore between the inside and outside cover of sandbox, arranges 1# lithium saponify oil sealing with sand block mouth and is used for carrying out sandbox waterproof, protection against the tide, prevented water from entering sandbox.After reaching the condition of turning, removing 1# lithium saponify oil sealing, taking out sand block sheet 6 from drawing sand mouth 7, to twitch with 1 cun of steel pipe get sand from drawing sand mouth 7.Complete after getting sand, rub sandbox back and forth, destroy the quartz sand between sandbox base 8 and slideway, thus the sandbox drawing out quartz sand is taken out.
Pour into quartz sand between the inside and outside cover of the utility model sandbox and directly do not import Rotary ball hinge or flat hinge into meet swivel bridges upper load, avoid rotor system to damage by larger load for a long time.When swivel bridges is constructed, the utility model directly can reduce the installation of swivel bridges rotor system and the workload of profit system transition, to avoid in sandbox quartz sand because of ratio and waterproof improper, sclerosis is caused to be hardened, can not completely remove, carry out damaging the main rotor system component such as slideway, spike when destructiveness is removed, cause serious consequence.
