Technical problem to be solved in the utility model is to provide a kind of raising construction economy usefulness, reduces construction cost, and below the shallow water river channel waterline of minimizing engineering resource consumption, large volume soil excavation attacks and occupies device.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: below a kind of shallow water river channel waterline, large volume soil excavation attacks and occupies device, this device is arranged on shallow water river surface to be onstructed, comprise one or more buoyant raft be connected to each other, pontoon bridge, many pontoons and tractor tug, described pontoon bridge is across many described pontoon tops, and be connected with described pontoon is dismountable, one end of described pontoon bridge is dismountable is connected to riverbank, the other end and described buoyant raft is dismountable links together, described pontoon and buoyant raft are all anchored in river bed by ship anchor, described tractor tug is by connector and described buoyant raft is dismountable links together.
The beneficial effects of the utility model are: described buoyant raft is drawn to job location by described tractor tug, under described buoyant raft, good ship anchoring is fixed, install described pontoon bridge, excavation equipment is reached on buoyant raft can be carried out excavation operation by the described pontoon bridge connecting riverbank, because described pontoon bridge is connected with described pontoon is dismountable, one end of described pontoon bridge is dismountable is connected to riverbank, the other end is connected described buoyant raft with dismountable, the i.e. all recyclable recycling of described pontoon bridge and buoyant raft, transport it into job location when needing to be in place and can to construct, improve construction economy usefulness, reduce construction cost, reduce engineering resource consumption.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described connector is cable, and described cable two ends are all fixedly connected with hook, and the two ends of described cable are connected with described tractor tug and buoyant raft hook respectively by described hook, and realize described tractor tug and be connected with described buoyant raft is dismountable, structure is reliable.
Further, described buoyant raft is cuboid box like, bottom it, corner is all fixedly connected with the first connecting hole, the ship anchor be connected with described buoyant raft is fixedly connected with described first connecting hole by iron chains, while ensureing the reliability of described buoyant raft carrying excavation equipment, guarantee the reliability that described buoyant raft is fixing in job location.
Further, described buoyant raft is provided with multiple, the corner, top of described buoyant raft is all fixedly connected with the second connecting hole, adjacent described buoyant raft is connected to each other through described second connecting hole by iron chains, when needs use multiple described buoyant raft to carry excavation equipment, connect the connecting hole on adjacent buoyant raft by iron chains, adjacent buoyant raft is coupled together, guarantee that structure is reliable.
Further, described pontoon bridge is formed by connecting by plurality of steel plates successively level is dismountable, removes each block of described steel plate and recyclable described pontoon bridge, is convenient to the recovery of described pontoon bridge.
Further, junction plate is provided with between two blocks of adjacent described steel plates, the two ends of described junction plate respectively by bolt corresponding with its two ends described steel plate dismountablely to link together, realize two pieces of adjacent dismountable connections of described steel plate, and structure is reliable.
Further, described pontoon bridge and described pontoon link together by reinforcing bar is dismountable, guarantee the reliability that described pontoon bridge is connected with described pontoon.
