Detailed description of the invention
By Fig. 1, Figure 2 shows that gravity type boat davit caisson gate of the present invention, its main body is the dock gate body 1 of a reinforced concrete structure, by a left side, right, before, rear wall and base plate are synthetic into the rectangular box of an opening upwards, front side wall 1.7 and middle recessed formation first top of rear wall 1.6, raised formation second top, both sides, left side wall 1.1 is equal with the second elevation of top with right side wall 1.2 absolute altitude, rectangular box inner chamber is provided with some pieces and extends from the interlaced longitudinal reinforcement concrete vertical clapboard 1.3 of base plate and transverse reinforcement concrete vertical clapboard 1.4, rectangular box is separated into the consistent rectangular cabin lattice 1.5 of cross-sectional sizes by described longitudinal direction and transverse reinforcement concrete vertical clapboard.The absolute altitude distinguishing adjacent the first from left longitudinal reinforcement concrete vertical clapboard 1.31 and a right longitudinal reinforcement concrete vertical clapboard 1.32 with arranged on left and right sides wall is identical with left and right sidewall, thus makes caisson gate main body form spill body structure low between the senior middle school of both sides.Front side wall top is provided with the dash steel counterfort extended between the first from left longitudinal reinforcement concrete vertical clapboard 1.31 and a right longitudinal reinforcement concrete vertical clapboard 1.32, and dash steel counterfort elevation of top is identical with left and right sidewall absolute altitude.
Specifically, described dash steel counterfort comprises the curved plate of the evagination of some left and right continued access, and adjacent curved plate 2 is connected to longitudinal reinforcement concrete vertical clapboard 1.3 top.Curved plate 2 is connected between the first from left longitudinal reinforcement concrete vertical clapboard 1.31 and a right longitudinal reinforcement concrete vertical clapboard 1.32, forms closed sealing face at the front side wall top of indent.
Also can see further from Fig. 3 ~ Fig. 8, described dash steel counterfort also comprises some pieces of vertical steel floors 13, described vertical steel floor is arranged at longitudinal reinforcement concrete vertical clapboard 1.3 top, weldering is located at the connection bit of adjacent two pieces of curved plates 2 and is extended to rectangular box inside, for the uplift force that opposing hydrostatic pressure produces steel floor 13, at vertical steel floor 13, reinforcing pull rod anchorage structures 3 is set away from one end of curved plate 2, whole steel floor 13 is anchored on dock gate body 1.
The horizontal shear beam 5 extended along front side wall is fixed with between described front side wall top and dash steel counterfort.For opposing level is to hydrostatic pressure, steel floor 13 connects as one with the horizontal shear H-shaped steel 14 of bottom, and shearing resistance H-shaped steel 14 withstands on shearing resistance beam 5, horizontal force is passed to dock gate body 1.
For guaranteeing swim stability and the squareness of drifting along in process of dock gate, between rectangular cabin lattice, intercommunicating pore is set.Rectangular cabin lattice are divided into four large independent ballast chambers by orientation.Such as, in this example, one co-exists in four lines, often row 10 arranges, altogether 40 cabin lattice, and every 40 cabin lattice are on average divided into the large independent ballast chamber in upper left, lower-left, upper right, four, bottom right.Using being positioned at the rectangular cabin lattice of dock gate four corners as equipment compartment, a diving pump 16 being set in cabin respectively, carrying out draining by drain hose 17.For ensureing that water pump maintenance is convenient, steel cat ladder 8 is set in equipment compartment, coolant inlet pipe 18 is set on the lattice sidewall of cabin simultaneously, the keying of coolant inlet pipe 18 is controlled by two-way water stop gate valve 19, open two-way water stop gate valve 19 when dock gate sinks and realize dock gate, during dock gate floating, open diving pump 16 and the water discharge in the lattice of cabin is realized dock gate floating, in caisson gate sink-float process, by controlling the squareness of the ballast water height adjustment dock gate of four large independent ballast chambers.
The raised lattice top, cabin being positioned at dock gate body both sides is provided with steel latticework bridge deck structure 15, People's Bank of China's steel structure bridge 10 is set at steel floor 13 top, a service platform be communicated with is formed on whole dock gate top, the control stalk of all gates is all arranged at dock gate top simultaneously, and handled easily personnel carry out that dock gate swims, mooring is deposited and the operation such as gate opening/closing on the operational platform; The left and right top side wall of dock gate is provided with six cover Double-pillar bitts 9, in the middle part of the forward and backward sidewall of dock gate, is provided with eight cover mooring rings 6, for stranded cable and mooring operation simultaneously.Crashproof cushion rubber 20 is set at dock gate arranged on left and right sides wall lateral surface, avoids dock gate to collide breakage when installation.At dock gate the first from left longitudinal reinforcement concrete vertical clapboard 1.31 and a right longitudinal reinforcement concrete vertical clapboard 1.32, steel cat ladder 11 and 12 is set, the upper and lower dock gate of handled easily personnel.Respectively bury a drain pipe 7 underground at dock gate body arranged on left and right sides wall, drain pipe is arranged butterfly valve 4 and control drain pipe keying.
Working process of the present invention is: when 1, dock gate sinks, open the coolant inlet pipe gate being arranged on dock gate four limit, to ballast chamber water filling, and controls flooding rate adjustment dock gate squareness by regulating gate opening; 2, after dock gate sinks to putting in place, close coolant inlet pipe gate outside depressed place, inside depressed place, coolant inlet pipe gate is held open state, carries out retaining operation in depressed place, and in the lattice of cabin, water level and water level in depressed place synchronously rise, and under hydraulic pressure effect, dock gate reaches homeostasis; 3, when dock gate floats, open the drain pipe butterfly valve be embedded on dock gate body, retaining in emptying depressed place, when water level flushes inside and outside depressed place, close all coolant inlet pipe gates of dock gate, open the diving pump in dock gate, the water in the lattice of cabin is discharged, put in place until dock gate floats; 4, when dock gate swims, keep ballast water height enough in the lattice of cabin, carry out stranded cable translation by the mooring ring of the Mooring Fittings and door body side surface that are arranged at dock gate top.
