Mud guard 4 is installed on the back side list slot channel steel 10 of double flute channel steel 11, is higher than water level 40cm in the installation of mud guard 4.General hydraulic reclamation area
Depth be not more than 5 meters when mud guard use common templates, if but hydraulic reclamation area depth it is excessive when, the mud guard of derrick lower layer
Steel plate need to be used, increases excessive to the pressure of derrick entirety to prevent the later period hydraulic reclamation area face Nei Ni so that plank sheathing deformation is even disconnected
It splits.
Safety measure
1, before the installation of derrick baffle, it is necessary to first check that whether there is or not deformation, inspection shafts whether there is or not run-off the straight, structural support for derrick
The outer mud identity distance of frame prevents withdrawal nozzle from discharging muddy water from water level elevation, and derrick and baffle water side sundries are cleared up in time, in order to avoid influence to move back
Mouth of a river draining.
2, derrick Internal baffle is increased when derrick periphery mud identity distance is more than 40cm from water level elevation, each baffle is only
Increase one layer, must not be to save trouble and disposably increase several layers of mud guard,
3, to ensure personnel safety when derrick mud guard is increased, the operation of withdrawal nozzle derrick should in strict accordance with following procedure into
Row:
1) derrick operates necessary two people every time, forbids upper derrick alone, forbids to operate after drinking；
2) safety cap, life jacket and on-slip shoes must be worn before the upper derrick of operator, waist system safety rope, safety rope is another
Operator is transferred on cofferdam to facilitate rescue when just in case drowned in end；
3) when operator confirms that mud guard needs to increase, first cofferdam side mudguard is leaned in installation, then installs two sides, keeps off
The sundries such as water plant, branch must not be mingled among plate and next layer of baffle contact；Both feet, which are trampled, when upstream face mud guard is installed is pacifying
The mud guard consolidated is filled, hand holds derrick or support；
4) necessary threading raincoat when flood season, the operation of rainy season derrick, forbidding to hold up an umbrella avoids wind-force excessive and overboard；Well on winter
First with accumulated snow or icing on spade cleaning baffle before frame operation.
It 5), must band before the upper derrick of operator when needing to remove mud guard to reduce heavy water in cofferdam during mud dumping area consolidation
Safety cap wears life jacket, is safety rope and it is necessary to be two people while operate；Derrick baffle is trampled, hand holds derrick or branch
Upstream face baffle is first removed in support, and then two sides are finally removed again by cofferdam side mudguard, and baffle must necessarily be placed in cofferdam side after removing
Recycling is forbidden to cause water outlet to block in directly throwing to cofferdam.
6) when derrick can not be climbed directly farther out apart from cofferdam, using ladder or rubber buoy.Use the length of ladder
It allows for meeting field demand with endurance, ladder must be firm, safe with derrick and cofferdam contact site, and ladder is erected at
Cofferdam position, which should stablize, not to be slided；
7) derrick mud guard increases recession from derrick, withdrawal nozzle drainage situation is observed on cofferdam, when draining has some setbacks again
Baffle is adjusted；
8) derrick dismounting recycling must can dispatch digging machine after the mud dumping area stabilization by consolidation and be operated.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
