A construction method of a supporting device for plain river dredging engineering comprises the following steps:

a. the support frame 2 is erected:

excavation foundation pit at the assigned position of both sides river bank, later concreting pile, after the concrete pile is done admittedly, fix fixing base 1 on the concrete pile, later with support frame 2 card income fixing base 1, slide block 19, slide fixing bolt 12 in fixed slot 10, later block 20 in fixing base 1 card income to screw up fixing bolt 12, accomplish the erection of support frame 2 and fix. The erection of the support frame 2 can make things convenient for the installation of the water retaining mechanism 18 on the one hand, guarantees the installation effect and the bulk strength of the water retaining mechanism 18, guarantees the water retaining capacity, and simultaneously, in the original river-crossing road dismantling process, can conveniently cross the river-crossing road dismantling, plays certain supporting role, makes things convenient for the clearing and transportation of rubbish. And the support frame 2 is convenient to erect in the erecting process, the construction efficiency is improved, and the time required by construction can be saved.

b. Assembling the water retaining mechanism 18:

and assembling the water retaining mechanism 18 on the shore for subsequent installation of the water retaining mechanism 18. The water retaining mechanism 18 is spliced on the shore, so that the connection effect of the water retaining mechanism 18 is improved, and the water leakage condition is avoided.

c. Installation of the water blocking mechanism 18:

firstly, a support rod 13 is driven into a soil layer punched at the side of a fixed seat 1, a clamping rod 15 of the support rod 13 is clamped into a clamping sleeve 14, then the support rod 13 is continuously pressed into the soil layer, the top surface of the support rod 13 is level with the top surface of a support frame 2, then bolts are screwed on the support rod 13 and the support frame 2 for fixing, then the position where a water retaining mechanism 18 is installed in advance is cleaned, a riverbed is cleaned, a groove opening is dug at the bank, the assembled water retaining mechanism 18 slides into the groove 17, then the water retaining mechanism 18 is knocked to be pressed into the bottom of the riverbed, and then the water retaining mechanism 18 is fixed by the bolts, so that the water retaining mechanism 18 is prevented from floating. In the water retaining mechanism 18 installation, set up bracing piece 13 earlier, the water retaining mechanism 18 of being convenient for is horizontal river, the construction of being convenient for, and the river bed bottom clearance then can guarantee after taking out the river, and the manger plate is difficult for the infiltration with regard to the river in the outside, has guaranteed that follow-up is the normal clear of dog.

d. Dismantling an original road:

and starting a water suction pump to pump off the river water in the water retaining mechanisms 18, then excavating the original river-crossing road by using an excavator, and cleaning the whole original road by matching with manual cleaning and carrying to ensure that no garbage is left in the riverbed between the water retaining mechanisms 18. The original road is dismantled, the overflowing area of the river channel can be guaranteed, the strong overflowing capacity can be guaranteed in the flood season, and the safety is guaranteed.

e. The supporting mechanism 3 is installed:

installing supporting component 47 on support frame 2, aim at mounting groove 45 with the lug 44 of horizontal pole 48 earlier, later rotate threaded rod 49 for the lug 44 of horizontal pole 48 blocks into mounting groove 45, screw up lock nut 50 chucking horizontal pole 48 after the horizontal pole 48 chucking, fix connecting plate 51 card on horizontal pole 48 again, splice supporting mechanism 3 on the river bank, block supporting plate 41 in the carriage 39 and fixed finishing, later with carriage 39 hoist and mount to support frame 2, and fixed. After the supporting mechanism 3 is spliced on the bank, the crane is only needed to be used for hoisting, the installation is very convenient, the crane is compared with the gradual installation on the supporting frame 2, the safety of constructors can be guaranteed, and the construction efficiency can be improved.

f. And (3) dismantling the water retaining mechanism 18:

the puller bolt 32 is loosened firstly, so that the water baffle 27 can be drawn out from the water baffle 26, river water overflows from the gap of the water baffle 27 and enters, after the water level at the two sides of the water baffle 27 is leveled, the water baffle 27 is drawn out from the water baffle 26, the sealing strip 28 is drawn out from the water baffle 26, then the connecting rod 25 is dismounted, and the connecting rod 25 and the water baffle 26 are recovered. After the river-crossing supporting bridge is erected, the water retaining mechanism 18 can be dismantled, the water levels on the two sides of the water retaining plate 27 are firstly leveled in the dismantling process, the water retaining plate 27 can be conveniently dismantled, the safety of constructors who dismantle the operation is guaranteed, the water retaining plate 27 is also thick when being dismantled, the connecting rod 25 and the water retaining rod 26 are integrally dismantled, and construction is convenient.

Step b, the detailed steps of assembling the water retaining mechanism 18 are as follows: the connecting sleeve 31 of the water bar 26 is sleeved in the connecting rod 25, then the water baffle 27 and the sealing strip 28 are respectively arranged in the water bar 26, then the connecting sleeve 31 is fastened to clamp the water baffle 27 from the top to the bottom in sequence, then the clamping bolt 37 is screwed to ensure the clamping of the sealing strip 28, and then the connecting sleeve 31 … … is fastened until all the water baffle 27 and the sealing strip 28 are fixed. The water retaining mechanism 18 is installed and fixed step by step, the fixing effect of the water retaining mechanism 18 can be guaranteed, the integral connection strength and the sealing effect of the water retaining mechanism 18 are guaranteed, and subsequent construction can be facilitated.

According to the invention, the water retaining mechanism 18 is used for temporarily blocking river water in the river dredging process, so that the original river crossing road can be conveniently cleaned, engineering garbage in the cleaning process is prevented from falling into the river water, the cleaning is convenient, the engineering period is shortened, meanwhile, the support frame 2 and the fixing base 1 are connected in a connection mode of the fixing bolt 12 and the fixing block 9, the connection is convenient, the connection effect is good, the support frame 2 can be conveniently and quickly erected and is convenient to construct, meanwhile, the support frame 2 plays a guiding role by utilizing the guide rod 5, so that the fixing installation of the fixing rod 4 is convenient, the arrangement of the fixing rod 4 in the fixing base 1 is ensured, on the other hand, a certain supporting role can be played, the bearing capacity of the support frame 2 is improved, and the installation accuracy and the installation. The water retaining mechanism 18 is arranged on the support rod 13, and can improve the bearing capacity and stability of the water retaining structure. The river water can be blocked, dredging and cleaning of a river-crossing road are facilitated, the river channel is not polluted, the construction period is effectively shortened, and the overflowing capacity and the traffic capacity of the river channel are ensured.

The invention adopts a, a support frame 2 is erected: b. assembling the water retaining mechanism 18: c. installation of the water blocking mechanism 18: d. dismantling an original road: e. the supporting mechanism 3 is installed: f. the water retaining mechanism 18 is detached, the steps are six, the steps are simple, the construction is convenient, the construction efficiency and the construction effect can be effectively improved, and the construction period is shortened.
