Described one is slided little Hanging Basket, and it is characterized in that described protection cross bar is arcuate structure, adjacent protection cross bar spacing is 0.5m.
Described one is slided little Hanging Basket, and it is characterized in that described operating desk is of a size of 1m × 1m, on operating desk, rational height is the fence of 1.2m.
Described one is slided little Hanging Basket, it is characterized in that described operating desk holder width is 1m.
Described a kind of construction technology utilizing the little Hanging Basket that slides to install intercepting drain, is characterized in that comprising the steps:
1) the little Hanging Basket that slides makes and installs:
The cross bar of Hanging Basket skeleton, extenal fixation mobile jib, internal fixtion mobile jib all adopt 8# channel-section steel to be welded, main contact bar between skeleton is the 8# channel-section steel of 1m length, the material of operating desk, protective guard adopts φ 16 indented bars, suspended basket component is pulley, 8 pulleys are set altogether, wherein head pulley is 4, and the first auxiliary pulley and each 2 of the second auxiliary pulley, be directional type pulley; Corresponding component be transported to Assembling good after, above the outside concrete anticollision barrier adopting human assistance vapour to hang to be arranged on and to have constructed, note the angle in place of Hanging Basket during installation, anti-limited slip wheel distortion, after installation in position, check that whether the walking system of Hanging Basket is normal;
2) Hanging Basket pressure testing
Carry out passing walking test by the load of two constructors after Hanging Basket installation, see whether it stablizes, pressure testing is observed its Hanging Basket and is stablized and without exceptionly just can descend cradle construction afterwards;
3) installation of tapping pipe, intercepting drain
A a people can only enter construction due to the little Hanging Basket that slides, and before installation, be first arranged side by side by two Hanging Baskets simultaneously, advance simultaneously, two people share out the work and help one another;
When b tapping pipe is installed, on bridge floor, every Hanging Basket must have people to be responsible for, and takes self-locking measure, prevents from producing the danger of automatically sliding because bridge longitudinal gradient is large;
Open the self-lock switch of associated pulleys when c Hanging Basket moves, after constructor below Hanging Basket leaves, Hanging Basket moves to bridge floor again;
D bridge deck drainage all adopts across interior even draining, tapping pipe spacing is arranged by 2 ~ 6m, intercepting drain is along the longitudinal setting that becomes band of bridge, and by 8 pulley support, Hanging Basket can slide gently, site operation personnel can promote the little Hanging Basket that slides, 4 meters, a joint of having constructed obtains water pipe, and working face moves forward 4 meters, and Hanging Basket just moves forward 4 meters, repeat, to having constructed.
