Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, four limbs thin-wall piers is that on concrete bearing platform 1, rectangular distribution is provided with four thin-wall piers 2, anti-ship hit facility on concrete bearing platform 1, the both sides that are positioned at four limbs thin-wall piers arrange a steel reinforced concrete column respectively as crash bearer 3, and the lateral wall of crash bearer 3 and thin-wall piers 2 arranges " D " type rubber fender 4 respectively; Horizontal beam 5 is set between the top of crash bearer 3 and thin-wall piers 2 and carries out level connection joint.
In concrete enforcement, corresponding vibrational power flow also comprises:
As shown in Figure 4, Figure 5, Figure 6 and Figure 7, horizontal beam 5 is shaped steel assembly, is to form triangular structure by a pair of V-shaped setting horizontal channel-section steel 51 and the horizontal i iron 52 be connected between a pair horizontal channel-section steel 51; Horizontal i iron 52 to be also connected on relevant position between two thin-wall piers 2 simultaneously jointly, one end of horizontal channel-section steel 51 is connected by junction steel plate 6 and chemical bolt 7 with the thin-wall piers 2 on correspondence position respectively, the other end of horizontal channel-section steel 51 be arranged on pre-embedded steel slab 8 in crash bearer 3 and be connected.
Crash bearer 3 is cast-in-situ concrete member, and the shaped steel in crash bearer 3 and skeleton reinforcing steel bar are embedded in concrete bearing platform 1; " D " type rubber fender 4 is adopt chemical bolt to be fixed on the lateral wall of crash bearer 3 and thin-wall piers 2, and the shaped steel in crash bearer 3 is " work " word steel.
As shown in Figure 2, " D " type rubber fender 4 is arranged in vertical on the lateral wall of crash bearer 3, " D " type rubber fender 4 is in being horizontally disposed with in thin-wall piers 2, and " D " type rubber fender 4 has spaced multiple tracks on the lateral wall of crash bearer 3 and thin-wall piers 2; As shown in Figure 8, the section of " D " type rubber fender 4 is made up of a straightway and an arc, fits with the surface of its straightway place plane and thin-wall piers 2 or crash bearer 3.
Take over control ship between in the present embodiment with the crash bearer 3 be arranged on concrete bearing platform 1 being to hit facility and be, be mainly used in the shock resisting bridge pier front boats and ships or fleet.Crash bearer 3 adopts diameter to be 1.6 meters of steel bar concrete structures, and concrete grade is C40, configuration indented bars and 12 I20a i iron in crash bearer and the pre-buried degree of depth to concrete bearing platform is 1 meter, effectively can increase intensity and the rigidity of crash bearer 3 with this.For increasing the lateral stability between crash bearer 3 and thin-wall piers 2, [the horizontal channel-section steel 51 of 40a is welded into compound beam and is rigidly connected between crash bearer 3 and thin-wall piers 2 to adopt two, simultaneously according to the principle of stable triangular, left and right two limb thin-wall piers 2 a horizontal i iron of I40a 52 and horizontal channel-section steel 51 are rigidly connected jointly.Should between to take over control the constructing operation that ship hits facility be carry out on concrete bearing platform, easy construction, takies space, navigation channel little.
Facility is hit with " D " type rubber fender 4 be arranged on thin-walled pier shaft 2 and anti-collision bridge pier 3 for direct anti-ship in the present embodiment, " D " type rubber fender energy-absorbing and energy consumption effect good, the height of " D " type of setting rubber fender 4 is between highest navigable stage and lowest navigable stage, " D " type rubber fender 4 becomes vertical and arranges on crash bearer 3, long 5 meters, horizontal spacing 0.42 meter between adjacent " D " type rubber fender 4, the excircle of crash bearer 3 is provided with seven roads altogether, and the area of setting accounts for the half of crash bearer surface area; " D " type rubber fender is in lateral arrangement on thin-wall piers pier shaft, and long 6.5 meters, the vertical spacing between adjacent " D " type rubber fender is 1 meter, and every thin-wall piers is respectively arranged with five roads.
It is hit facility and direct anti-ship collision device combines to take over control ship that the anti-ship of four limbs thin-wall piers in the present embodiment hits facility, has the ability of the direct impact damage of enough opposing vessels or other floating things, ensures bridge use safety.
