Abstract
The utility model discloses a sand cylinder type temporary bridge support, and relates to a temporary bridge support. The temporary bridge support comprises an outer cylinder (1) and an inner cylinder(2) sleeved in the outer cylinder (1), wherein the bottom of the inner cylinder (2) extends out from the hole of the outer cylinder (1); concrete (3) is poured in the inner cylinder (2); sand (4) isfilled between the inner cylinder (2) and the outer cylinder (1); a sand discharge tube (5) communicated with the inside of the outer cylinder (1) is arranged at the lower part on the outer surface ofthe wall of the outer cylinder (1); and a sand discharge valve (6) I arranged on the sand discharge tube (5). The inner cylinder (2) and the outer cylinder (1) are made of steel. The thickness of steel materials is above 7 mm. The utility model has the advantages of low cost, quick construction speed, convenient assembly and disassembly and high reliability.
Description
Technical field
The utility model relates to a kind of bridge temporary support, relates in particular to a kind of sand cartridge type bridge temporary support.
Background technology
The temporary support that uses in bridge construction be because need bear very big load, requires temporary support should have that intensity height, cling property are good, the characteristics of easy-clear, and what generally use at present is the sulphur-bonded mortar temporary support.Sulphur-bonded mortar be meant with sulphur be heated to uniform temperature form liquid and fully the dehydration back add preheating and drying acid-resistant powder and the fines of establishing when ratio below the particle diameter 1.24mm, a kind of novel thermoplastic material of formation.Sulphur-bonded mortar is prone to delamination, Yong Pao in the process of building, knock phenomenons such as the free sound in surface, leakiness after the sclerosis; Later stage also appears in while pre-buried resistance wire easily can't be by the problem of electrical heating dismounting; Being heated inhomogeneous and boiling temperature of sulphur boil in the process at sulphur-bonded mortar in addition, owing to will produce a large amount of toxic gas SO inadequately
2Therefore, when sulphur-bonded mortar boiled, the constructor will be with anti-poison respirator, wears frog suit and keep the construction plant to ventilate, in order to avoid poison, the complicated efficient of total construction technology is low, cost is high.
The utility model content
At the problem that above-mentioned prior art exists, the utility model provides a kind of sand cartridge type bridge temporary support, has that cost is low, speed of application fast, an easy accessibility, high reliability features.
The technical solution of the utility model is: a kind of sand cartridge type bridge temporary support, comprise outer drum and be placed in the outer drum and the interior drum that stretches out from outer drum bung at the bottom of its barrel, fill concrete in the interior drum, heap sand between the inside and outside drum, outer drum bucket wall appearance bottom be provided with bucket in be communicated with put sandpipe, put sandpipe and be provided with and put the sand valve.
As preferably, described inside and outside drum is formed from steel.
As preferably, described steel thickness is more than the 7mm.
The beneficial effects of the utility model are: whole temporary support is made up of inside and outside drum, fills concrete in the interior drum, heap sand between the inside and outside drum, and simple and reliable for structure, cost is low.The sand of filling between the inside and outside drum is raised certain altitude with interior drum, regulates the quantity of dress sand in the outer drum, can regulate height of support; Finish using, can open and put the sand valve and put sand, use, dismounting is quick and convenient from putting sandpipe.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model embodiment;
Fig. 2 is the use schematic diagram of the utility model embodiment.
The specific embodiment
As a kind of embodiment of the present utility model, as depicted in figs. 1 and 2, a kind of sand cartridge type bridge temporary support, comprise outer drum 1 and be placed in the outer drum 1 and the interior drum 2 that stretches out from outer drum 1 bung at the bottom of its barrel, fill concrete 3 in the interior drum 2, heap sand 4 between the inside and outside drum 2,1: between the bucket wall of inside and outside drum 2,1, and heap sand 4 at barrel end of the bung of interior drum 2 and outer drum 1,1 barrel of wall appearance of outer drum bottom be provided with bucket in be communicated with put sandpipe 5, put sandpipe 5 and be provided with and put sand valve 6.Described inside and outside drum 2,1 is formed from steel.Described steel thickness is more than the 7mm.The sand 4 of filling between the inside and outside drum 2,1 is raised certain altitude with interior drum 2, according to the quantity that the design height of support is regulated dress sand 4 in the outer drum 1, can regulate height of support, till reaching requirement; Drum is laid bearing pad stone 71 time outside, and interior drum 2 supports and presets T beam 8.After all construction is finished, when temporary support need be removed, twist and put sand valve 6, water pipe dashes puts sandpipe 5, and the sand 4 in the outer drum 1 promptly flows out from putting sandpipe 5 along with current, finishes the transformation from the freely-supported to the continuous system.After removing temporary support, sand tube temporary support can also recycle.
Claims (3)
1. sand cartridge type bridge temporary support, it is characterized in that: comprise outer drum (1) and be placed in the outer drum (1) and the interior drum (2) that stretches out from outer drum (1) bung at the bottom of its barrel, fill concrete (3) in the interior drum (2), heap sand (4) between the inside and outside drum (2,1), outer drum (1) bucket wall appearance bottom be provided with barrel in be communicated with put sandpipe (5), put sandpipe (5) and be provided with and put sand valve (6).
