Description
Technical field
The invention belongs to harbour, coastal engineering and basin water body environmental protection searching field, it is big to relate generally to harbour, coastal engineering
The concrete prefabricated heavy mail structure of steel bar and construction method, specifically a kind of box culvert and caisson combining structure and construction method.
Background technology
Concrete box culvert is used for draining or water intaking, or water system ensures water quality inside and outside linking up, and general weight is smaller, using hanging
Fortune is installed or dry application work is cast-in-place on land.When box culvert length reaches tens meters of thousands of ton hours of weight, at sea install very tired
Difficulty, lifting needs super-huge crane ship, due to as the region that blocks water that caisson surrounding and underseal close, not adopted during transportation by driving in the sea
Take border seal and help floating measure, box culvert needs a plurality of ship auxiliary haul in the easy unstability of sleeve configuration, and transport mounting cost is high, work
Phase is grown.Large-sized reinforced concrete caisson is widely used in gravity type quay, shore protection, breakwater engineering, in large scale prefabricated field
It is prefabricated, then launching caisson, transportation by driving is pulled over long distances to infield.
Basin did not use water tank to contain substantially at present in port engineering at present, but for some to water quality, environmental requirement
High harbour water area, there is the demand for setting water tank to contain, and cross water tank and contain towards off-lying sea, by wave stroke, if perforate
Position is improper to be introduced directly into outer sea wave in basin, influence the wave condition in basin, or silt is introduced into basin.
Therefore, in port and coastal engineering, how to be installed using the stability of large scale prefabricated reinforced concrete caisson,
Solve the installation question that swims of box culvert in large size, reduce installation number, reduce engineering cost and construction period, this is current this area
Technical problem urgently to be resolved hurrily；In addition, how effectively to solve basin and the water body of off-lying sea is exchangeed problem, ensure the water quality of basin,
And wave thoroughly is reduced, protect the installation security in basin, and urgent problem to be solved.
The content of the invention
The present invention provides a kind of box culvert and caisson combining structure and construction method, mainly solves the installation of swimming of box culvert in large size
Difficult and unsafe problem, and water, remote transportation by driving and installation number under precasting yard are reduced, reduce engineering cost and construction
Duration；Further objective is that reasonable Arrangement crosses water box culvert structure, the water body for solving basin and off-lying sea is exchangeed problem, and ensures port
The water quality in pond, and wave thoroughly is reduced, protect the installation security in basin.
Technical scheme provided by the invention is：A kind of box culvert and caisson combining structure, it is characterised in that the box culvert is with sinking
Case combining structure included water tank culvert, Large Caisson, and the water tank excessively contains and the inside of Large Caisson is penetrated by reinforcing bar, and integrally
Casting concrete forms box culvert and caisson combining structure, and the box culvert forms gravity type quay or breakwater with caisson combining structure
Levee body part, be below the block ground mass bed on sea bed, its top is armored concrete breastwork and block stone rib body, and top is face
Rotating fields.
Improvement to above-mentioned technical proposal：The water tank excessively, which is contained, includes front wall, rear wall and two sides side wall, and the water tank of crossing is contained
Water tank culvert excessively is at least separated to form twice water stream channel by the interior mediastinum wall that is provided with, and 2 holes are at least opened up on the mediastinum wall.
Further improvement to above-mentioned technical proposal：Through hole, and institute are provided with the front wall and rear wall of the culvert of water tank excessively
State that through hole is corresponding with the water stream channel, the upper edge elevation of the through hole is below 1.5 times of Design Waves of design high-water, institute
The lower edge elevation of through hole is stated more than described piece of ground mass bed top surface 2m.
Further improvement to above-mentioned technical proposal：The water tank of crossing contains pre-embedded bolt on the through hole of front wall and rear wall, institute
Stated detachable installation steel on the through hole of water tank culvert front wall and rear wall to seal up a door, on the through hole of the front wall for crossing water tank culvert and rear wall
Trash rack is installed, the rear wall top portion for crossing water tank culvert sets pvc pipe to basin side.
Further improvement to above-mentioned technical proposal：Tabula is set between the mediastinum wall and its side wall crossed during water tank is contained
Plate, the diaphragm plate set 1/3~1/2 that height is hole height on the front wall and rear wall, and the diaphragm plate centre bit
In on the line of centres of the through hole on the front wall with through hole on rear wall.
Further improvement to above-mentioned technical proposal：The Large Caisson is rectangular box, including caisson front wall, caisson
Wall and caisson side wall afterwards, inlet opening are provided with wall and caisson side wall after the caisson front wall, caisson, wherein there is a face caisson
Side wall shares with crossing the side wall that water tank is contained, and Large Caisson is divided into by the caisson cross wall and mediastinum wall set in the Large Caisson
Multiple caisson cabins lattice, each caisson cabin lattice are built with block stone rib body.
