Description
Technical field
The present invention relates to a kind of mounting method of counterfort.
Background technology
Gravity retaining structures engineering on the water is used widely, and the gravity retaining structures of water project usually adopts prefabricated reinforced concrete dust block body, installs on the underwater bedding, and the backfill filler forms soil-baffling structure behind the dust block body.The dust block body has counterfort, caisson, hollow square, L shaped retaining wall, closed square etc.Under many circumstances, " hollow square " is called as " little caisson ".
Utilizing partly dives refutes transportation, the installation of carrying out caisson, has solved rising of Large Caisson and has re-mounted a difficult problem, and Large Caisson is widely used.
The reasonable stress of buttressed quay wall, material savings has economic advantages.The counterfort structure is because installation question, is restricted in the application of large pier.Solve the installation question of counterfort, have remarkable economic efficiency.
For this reason; We propose to utilize the auxiliary method that counterfort is installed of buoyancy tank; Consider to utilize the buoyancy of buoyancy tank overcome counterfort from gravity, thereby realize utilizing small-sized crane ship that large-scale counterfort is installed, perhaps counterfort is under the situation of floating state at buoyancy tank buoyancy; Utilize anchorage cable stretching that counterfort is located, utilize tidewater to descend or buoyancy tank is poured water to sink to realizing the in place of counterfort and install.
Buoyancy tank can adopt the steel buoyancy tank, also can adopt the glass fiber reinforced plastic buoyancy tank, and many productions that produce are arranged at present.Buoyancy tank is provided with intake-outlet and air inlet/outlet, and gauge tap is set.Structure and anti-collision structure that buoyancy tank setting is connected with counterfort.Buoyancy tank can adopt single buoyancy tank or a plurality of buoyancy tank, and buoyancy tank also can adopt the combination buoyancy tank that is connected to form one by a plurality of independent buoyancy tanks.In the process that counterfort is installed, the filled water amount of each buoyancy tank can be controlled respectively.Buoyancy tank can recycle.
Utilize the auxiliary flow process that counterfort is installed of buoyancy tank: before (1) counterfort was installed, buoyancy tank was fixed on the counterfort structure, under counterfort, before the water, buoyancy tank is inflated certain pressure, and closed Inlet and outlet water, turnover air cock; (2) in the counterfort sinking process, buoyancy tank progressively sinks to getting in the water, and buoyancy progressively increases, and counterfort sinks to desired location, and the buoyancy of buoyancy tank performance reaches the designing requirement that counterfort is installed; (3) utilize the auxiliary counterfort of slinging of crane ship, counterfort is installed on the bedding, or utilizes anchorage cable stretching that counterfort is located, utilize tidewater to descend or buoyancy tank poured water to make counterfort sink to be installed on the bedding; (4) after counterfort is installed, open the water inlet of buoyancy tank water inlet, make the gravity of buoyancy tank and buoyant equilibrium be in floating state, open being connected of buoyancy tank and bearing pin, buoyancy tank is towed out between the counterfort floor, leave subsequent use place in.Accomplishing counterfort thus installs.
Buoyancy tank can be accomplished in several ways with being connected of counterfort structure.Buoyancy tank can be fixed on the floor of counterfort, and buoyancy tank also can be fixed on the base plate of counterfort, and buoyancy tank can also be separately fixed on the different component of counterfort, specifically can design according to requirement of engineering.
Buoyancy tank and counterfort structure be connected with multiple mode: mode one, the buoyancy tank hoist cable is connected on the bearing pin, bearing pin is installed in the lifting hole(eyelet) of floor of counterfort; Mode two is connected the buoyancy tank hoist cable on the bearing pin, and bearing pin is installed in the bearing pin base on the counterfort base plate; Mode three is connected the buoyancy tank hoist cable on the suspension rod, and suspension rod injects in the lifting hole(eyelet) box and turn 90 degrees.
Being provided with on the base plate of counterfort under the situation of underframe longitudinal member, also can buoyancy tank be connected on the underframe longitudinal member.Under the situation of special-shaped caisson, also can buoyancy tank be connected on the withe of special-shaped caisson.
Between the counterfort installation period, can adopt fixedly buoyancy tank of temporary structure, overcome the external force such as wave, current of construction period buoyancy tank, the plan-position and the upright position of control buoyancy tank.
After the counterfort installation, preformed hole, the built-in fitting installed are handled according to engine request.
Utilize buoyancy tank can also assist structures such as special-shaped caisson, large cylinder are installed, its method is similar with the auxiliary installation of buoyancy tank counterfort.For the ease of describing, we conclude special-shaped caisson in the special-shaped counterfort and describe.
Utilize buoyancy tank that counterfort is installed, can promote the application of counterfort structure, the advantage of performance buttressed quay wall is saved concrete and steel project, under usable condition, has significant comprehensive benefit.
For this reason, we propose to utilize the auxiliary method that counterfort is installed of buoyancy tank to water project.
