Description
Technical field
The present invention relates to the bridge cast-in-place support, be specifically related to a kind of large-span steel pile tube cast-in-place support waterborne and building method thereof.
Background technology
Common bridge cast-in-place support in the construction mostly be to land scaffold building with full hall on land, and cast-in-situ concrete adopts Hanging Basket to construct piecemeal more on the water.When the bridge bottom surface is positioned at the waters, banket in water and build the island and set up full hall and land scaffold, very difficult assurance is banketed and is built the stability on island, exists problems such as differential settlement, constructional difficulties, polluted river channel, safety factor are low, when if the river course is darker, also can increase cost.Under the situation that is designed to bridge beam body integral cast-in-situ in water, cast-in-situ concrete construction waterborne can not be adopted Hanging Basket, and disposable concreting amount is bigger, when span is excessive, must guarantee the rigidity control of support, avoid the beam body more crack to occur because of the support sedimentation.So, need seek a kind of cast-in-place support that can adapt to large span waterborne.
Summary of the invention
The purpose of this invention is to provide a kind of large-span steel pile tube cast-in-place support waterborne, its structure is simple and clear, good integrity, and span is big, good rigidity, stable high, and installation and removal easily, is fit to large-span continuous beam integral cast-in-situ waterborne and constructs.
The present invention also provides a kind of building method of large-span steel pile tube cast-in-place support waterborne, and this method is easy to operation, safety factor is higher, can guarantee that sedimentation is less in the construction of continuous beam integral cast-in-situ, guarantees quality of concrete.
A kind of large-span steel pile tube cast-in-place support waterborne of the present invention, comprise many placing of reinforcements concrete foundation pile, every row is made up of many reinforced concrete foundation stakes, it is characterized in that: the bottom of every reinforced concrete foundation stake is fixed on below the bottom, be fixedly connected with a steel pipe pile in the upper end of every reinforced concrete foundation stake, upper ends at every row's steel pipe pile has a transverse distribution beam, shellfish thunder sheet be located at each transverse distribution beam above, each is arranged between the shellfish thunder sheet and connects with shellfish thunder sheet bracing frame, sleeper is located on the shellfish thunder sheet, bowl button be erected at sleeper above; The model of the cast-in-situ continuous beam of being made up of the lumps of wood and template is located at bowl to be buckled on the support.
This steel pipe pile cast-in-place support adopts the steel pipe pile of Φ 80cm as buttress, and as the transverse distribution beam, shellfish thunder sheet is laid on and forms the simply supported beam system on each transverse distribution beam with two limb I56 i iron.
Described a kind of large-span steel pile tube cast-in-place support waterborne is welded with a capital steel plate in the upper end of every steel pipe pile, is welded with polylith below the capital steel plate and between the outer wall of steel pipe pile and strengthens steel plate, and the transverse distribution beam is placed directly on the capital steel plate.
Described a kind of large-span steel pile tube cast-in-place support waterborne, steel plate at the bottom of the lower end of every steel pipe pile is welded with post is welded with polylith and strengthens steel plate on steel plate at the bottom of the post and between the outer wall of steel pipe pile.
The building method of a kind of large-span steel pile tube cast-in-place support waterborne of the present invention, its step is as follows:
The first step, the drilling construction that carries out the reinforced concrete foundation stake, a plurality of foundation piles of every gang drill hole, distance between borehole is 2.5m to 5m, row-to-row distance equates, is 18m; When the reinforced concrete foundation stake is built, steel plate at the bottom of the post is embedded in the end face of reinforced concrete foundation stake;
Second step, the steel pipe pile of welded and installed on steel plate at the bottom of the post, at the upper end of steel pipe pile welding capital steel plate, and between the outer wall of steel pipe pile and steel plate at the bottom of the post 6 reinforcements of welding steel plates;
The 3rd step, set up the transverse distribution beam of making of two limb I56 i iron at the top of every row's steel pipe pile, again shellfish thunder sheet vertically is laid on each transverse distribution beam, each is arranged between the shellfish thunder sheet and connects with shellfish thunder sheet bracing frame;
The 4th step laid railway sleepers on shellfish thunder sheet, directly set up a bowl button support on sleeper, and the model of the cast-in-situ continuous beam of being made up of the lumps of wood and template is installed at bowl button support.
Beneficial effect of the present invention: drilled pile basis and steel pipe pile are all stressed clear and definite, easy and simple to handle, have evaded the security risk of shining because of reasons such as calculating are inaccurate; With the Bei Leiliang that shellfish thunder sheet is set up, have in light weight, easy accessibility, characteristics such as the load ability to bear is big.Prove that by example the steel pipe pile cast-in-place support of this kind form can realize the continuous beam integral cast-in-situ of 110m span, settling amount belongs to uniform settlement at 1-2cm, has saved about 700,000 yuan of cost than other job practices.
