Description
Technical field
The utility model relates to a kind of Gravity Type Casisson Berth operating technique, especially a kind of for measuring the water-bed bedding of deepwater regions apart from the device of water surface distance, belongs to port engineering technical field.
Background technology
Gravity Type Casisson Berth construction needs first that water-bed bedding is smooth, by frogman's underwater operation, will specify construction area to flatten, Divers is under water with the sand pocket designed elevation pier of banking up, the water surface is stretched out in measuring staff upper end, survey crew is measured measuring staff absolute altitude by spirit-leveling instrument on the bank, thereby designed elevation is caused under water, and diving operation personnel carry out smooth according to surveyed elevation control to water-bed foundation trench, in this process, need to repeatedly sound the depth of the water.Bathymetric survey, for the smooth construction of water-bed foundation trench provides a large amount of bathymetric datas reliably, can carry out follow-up harbour caisson location and installation construction smoothly.The workload of bathymetric survey is very large, and bathymetric survey speed directly affects the speed of application of harbour, and the precision of surveying work directly affects the construction quality of Gravity Type Casisson Berth.
The steel pipe that the measuring staff of existing bathymetric survey device increases progressively 2～3 diameters is welded into whole steel pipe of lower thick upper thin from bottom to up, during measurement, loop wheel machine on station keeping ship hangs measuring staff and puts under water, measuring staff bottom is leaned against on water-bed foundation trench, the water surface is stretched out in measuring staff upper end, and its upper end is surfaced one long section.The measuring staff upper end verticality that observation is surfaced, adjusts in time, makes measuring staff as far as possible in plumbness, then Sopwith staff is leaned against to the measuring staff side of surfacing, and available spirit-leveling instrument is on the bank measured.Before starting operation, accurately measure measuring staff and establish measurement Sopwith staff place to the distance of bottom, so that survey crew calculates measuring staff elevation of bottom.
There is following problem in this measurement mechanism:
When slinging measuring staff, loop wheel machine cannot guarantee that it is vertical; Because measuring staff length is longer, current must cause middle bent to its impact, repeatedly use rear bending more serious, and bending error cannot be estimated; When putting measuring staff at every turn and playing measuring staff, more easily cause measuring staff flexural deformation.The measuring staff that invar pipe is made weighs more than 110Kg, and measuring staff moves difficulty in use, and loop wheel machine handling measuring staff wants many people to coordinate the position that could accurately move to appointment.Because the error of measurement mechanism causes flattening operation precision under water, cannot reach designing requirement, directly affect the construction quality of harbour caisson location and installation under water.The ship side rocking because of station keeping ship during use often telescopes measuring staff, makes it cannot operation.
