Abstract
The utility model provides a sand section of thick bamboo for whole decline of bridge, the barrel is equipped with the grit in, has pressed the piston above the grit, and the outer wall and the sand section of thick bamboo inner wall friction connection of piston, and the piston top even has the backup pad, and the inside concrete core that is filled with of piston, the section of thick bamboo wall of sand section of thick bamboo are made by the steel sheet, and sand discharge opening has been opened to sand section of thick bamboo bottom symmetry, and sand discharge opening and sand discharge nozzle stub intercommunication, the outer wall upper car of sand discharge nozzle stub have the screw thread, and with seal. The problem of the whole steady decline of bridge has been solved, has simple structure, low in cost, safe and reliable's characteristics.
Description
Technical field
The utility model relates to the bracing or strutting arrangement that a kind of bridge steadily descends.
Background technology
Along with the development of road traffic is perfect, some river course of opening the navigation or air flight originally no longer needs navigation.The past get very high bridge because of navigation needs frame on these river courses, and its high embankment often causes very big load to abutment, serious even entail dangers to bridge security, and two ends not only high but also long leading the way also greatly influence civic landscape and land used simultaneously.Therefore, it is imperative these bridges to be reduced transformation.Old bridge reduces the following two kinds of methods that mainly contain of transforming: the one, hang the top girder after removing bridge floor, and set up girder again and the bridge floor of constructing again after waiting to reduce bridge pier; The 2nd, with one section column of amputation after the bent cap firm supporting, utilize hydraulic jack with bent cap and on bridge deck drop to design elevation synchronously, connect column again.First method since will with bent cap and on bridge deck Remove All or remove after more again the construction, its essence is exactly that the part more than the bent cap is removed reconstruction, therefore caused significant wastage, be a kind of very uneconomical and take a lot of work, effort, time-consuming conventional method.Second method is because the large-tonnage hydraulic jack is relatively more expensive, and the bridge that descends synchronously needs to drop into simultaneously a considerable amount of hydraulic jack again, so its construction cost can be very high.The utility model steadily descends and a kind of simple, economical, the safe and effective device of proposition at integral bridge just.
The utility model content
Utility model provides a kind of sand tube that integral bridge descends that is used for, and solve existing old bridge and reduce rebuilding construction method cost height, the technical problem of complex process.
The technical scheme that its technical problem that solves the utility model adopts is:
This sand tube that is used for integral bridge decline, sand is housed in the cylindrical shell, be pressed with piston above the sand, the outer wall of piston is connected with wall friction in the sand tube, and top land is connected with gripper shoe, it is characterized in that: above-mentioned internal piston is filled with concrete core, the barrel of sand tube is made by steel plate, and sand tube bottom symmetry has puts the sand mouth, puts the sand mouth and puts the sand short tube and be communicated with, the outer wall of putting the sand short tube screw thread of having got on the bus, and be threaded with blind nut.
The beneficial effects of the utility model are as follows: simple in structure, easy to operate, cheap, safe and reliable, steadily effective, and solve old bridge and reduced rebuilding construction cost height, the technical problem of complex process.The utility model is compared with first kind of prior art, can not destroy deck paving, and operating expenses is low, and construction operation does not need the place all under bridge; Compare with second kind of job practices, use cheap sand tube to replace expensive large-tonnage hydraulic jack, construction cost is reduced greatly.In construction, can use the sand tube of some to finish integral bridge and steadily descend.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of sand tube.
Reference numeral: 1-barrel, 2-sand, 3-piston, 4-gripper shoe, 5-concrete core, 6-are put the sand mouth, 7-is put sand short tube, 8-blind nut.
The specific embodiment
Embodiment is referring to Fig. 1, this sand tube that is used for integral bridge decline is equipped with sand 2 in the cylindrical shell, be pressed with piston 3 above the sand, the outer wall of piston 3 is connected with wall friction in the sand tube, top land is connected with gripper shoe 4, it is characterized in that: above-mentioned piston 3 inside are filled with concrete core 5, and the barrel of sand tube 1 is made by steel plate, sand tube bottom symmetry has puts sand mouth 6, put the sand mouth and put sand short tube 7 and be communicated with, the outer wall of putting sand short tube 7 screw thread of having got on the bus, and be threaded with blind nut 8.
The label of concrete core 5 is C30.The barrel 1 of steel cylinder is made by the 12mm steel plate, each sand tube bottom have two internal diameters be 30mm put sand mouth 6, seal by the blind nut more than the diameter 50mm 8.Sand 2 in the sand tube can be selected peace and quiet, dry quartz sand for use.
Claims (1)
1. one kind is used for the sand tube that integral bridge descends, sand (2) is housed in the cylindrical shell, be pressed with piston (3) above the sand, the outer wall of piston (3) is connected with wall friction in the sand tube, top land is connected with gripper shoe (4), it is characterized in that: above-mentioned piston (3) inside is filled with concrete core (5), the barrel of sand tube (1) is made by steel plate, sand tube bottom symmetry has puts sand mouth (6), put the sand mouth and put sand short tube (7) and be communicated with, the outer wall of putting sand short tube (7) screw thread of having got on the bus, and be threaded with blind nut (8).
