It is right that following through specific embodiment the utility model provides a pair of further more detailed explanation is made to water conservancy diversion breakwater based on pile foundation structure:
example 1
The water conservancy diversion breakwater based on pile foundation structure of this embodiment: please refer to fig. 1, which includes comb-type close-packed piles for guiding flow:
when the wharf is small in grade and shallow in water depth, the comb-type close-packed pile piles are arranged below the wharf.
Specifically, when the wharf is small in grade and shallow in water depth, the wharf comprises a beam 6, a plurality of superposed panels 2 arranged above the beam 6 and a prefabricated longitudinal beam 7 arranged on the upper surface of the beam 6 and used for supporting the superposed panels 2, a plurality of wharf pile foundations 9 with bottoms inserted into the water are arranged on the lower surface of the beam 6, a sea side wave dissipation plate 3 and an inner side wave dissipation plate 4 are respectively arranged at two ends of the beam 6, and rubber fenders 5 parallel to the sea side wave dissipation plate 3 and the inner side wave dissipation plate 4 are arranged at adjacent positions of the sea side wave dissipation plate 3 and the inner side wave dissipation plate 4; in addition, a bollard 1 is arranged on the sea side wave dissipation plate 3 and the inner side wave dissipation plate 4;
the comb-type close-packed pile comprises a cap beam 8 and close-packed piles 10 arranged at a plurality of intervals at the lower part of the cap beam 8, wherein the close-packed piles 10 are positioned between wharf pile foundations.
The wharf pile foundations 9 are arranged vertically or obliquely relative to the cross beam 6.
The close-packed piles 10 adopt PHC piles, steel pipe piles or rock-socketed piles, and the pile clear distance is larger than or equal to 100 mm.
The mud surface of the comb-type close-packed pile is provided with a riprap protecting bottom 11 according to the scouring condition.
When the wharf is in a small grade and shallow in water depth and mainly improves the berthing condition of a boat, comb-type close-packed piles are arranged below the wharf, the concrete structure is shown in figure 1, the wharf adopts a high-pile plate beam type structure, the upper structure adopts a cast-in-place cross beam 6, a prefabricated longitudinal beam 7 and a superposed panel 2, and the cast-in-place cross beam, the prefabricated longitudinal beam and the superposed panel are connected into a whole through a cast-in-place surface layer. Comb-type close-packed piles are arranged below the wharf to dissipate waves, PHC piles, steel pipe piles or rock-socketed piles can be adopted as the close-packed piles 10 according to the geology, the wave dissipation performance and pile sinking requirements need to be considered in the pile spacing, the pile spacing is not smaller than 100mm, section model tests are preferably carried out to determine, and wing-shaped structures such as steel plates can be arranged between the close-packed piles 10. The mud surface of the comb-type close-packed pile is provided with a riprap protecting bottom 11 according to the scouring condition. The comb-type densely-arranged pile tops are connected by adopting a cast-in-place cap beam 8, and the elevation of the top of the cap beam 8 needs to be set by combining the design water level and the elevation requirement of the wharf upper structure. The comb-type diversion embankment structure can be combined with a wharf structure for arrangement, is used for guiding the flow state of berths on two sides of the wharf, is good in diversion effect, relatively short in embankment body length, small in engineering quantity, high in construction speed, small in sea surface area, small in influence on marine environment, and meanwhile successfully achieves the aim of improving the berthing stability performance of the ship.
The application range is as follows: this kind of comb type close row pile structure scheme based on pile foundation structure, the above-mentioned technical scheme for embodying its water conservancy diversion effect, this structural scheme also can be through adjusting its pile interval, pile type, elevation, structural style, the position isoparametric of arranging, realizes its wave prevention and wave elimination function.
Compared with the traditional manual measures, the structure can effectively save the engineering investment, can play better effects of diversion and wave blocking, or can optimize the structural scheme by considering the arrangement of flow-assisting (wave) plate measures in a certain height range of the pile body.
The operation mode is as follows:
this novel structure is based on pile foundation structure, and conventional driven pile construction process does: throwing stone to protect bottom → driving dense row piles → driving inclined strut piles → pouring pile core and cap beam in vertical mould. The pile foundation type of the cast-in-place pile and the rock-socketed pile is required to be carried out according to the construction procedures of the cast-in-place pile and the rock-socketed pile.
Because the close-packed piles 10 are close to the wharf structure, the wharf pile foundations 9 need to be arranged to avoid the embankment body area. During construction, the wharf pile foundation needs to be constructed with the close-packed piles in a coordinated mode, and construction efficiency is improved.
Example 2
The water conservancy diversion breakwater based on pile foundation structure of this embodiment: referring to fig. 2, 3 and 4, the pile comprises comb-type close-packed piles for guiding the flow:
when the wharf is in a large grade and has a large water depth, the comb-type close-spaced piles are arranged behind the wharf or between the front berth and the rear berth.
Specifically, when the wharf is large in grade and water depth, the wharf comprises a sea side wharf and a shore side wharf provided with a ship mooring pier 12, and the comb-type close-spaced piles are arranged between the sea side wharf and the shore side wharf;
comb type close-packed pile includes the cap roof beam and sets up the close-packed pile 10 that a plurality of intervals that 8 lower surfaces of cap roof beams bottom inserted in the waters set up, the both sides of close-packed pile 10 are provided with the bracing column, the upper end of bracing column supports the lower surface setting of cap roof beam 8.
The close-packed piles 10 are steel pipe piles or rock-socketed piles, and the pile clear distance is larger than or equal to 100 mm.
The mud surface of the comb-type close-packed pile is provided with a riprap protecting bottom 11 according to the scouring condition.
When the wharf is in a large grade and has a large water depth, the flow guiding is conducted to smooth the flow state of the mooring area of the large ship, the comb-type close-packed piles are arranged behind the wharf or between the front berth and the rear berth, the comb-type close-packed piles have the same structure under the two conditions, the arrangement between the front berth and the rear berth is taken as an example, and the specific structure is shown in fig. 2. The wharf adopts a high pile plate beam type structure, the upper structure adopts a cast-in-place beam 6, a prefabricated longitudinal beam 7 and a superposed type panel 2, and the cast-in-place beam, the prefabricated longitudinal beam and the superposed type panel are connected into a whole through a cast-in-place surface layer. Set up comb type close-packed pile in the middle of the both sides pier and carry out the water conservancy diversion, close-packed pile can adopt steel-pipe pile or socketed pile according to the depth of geological water, and the clear distance of stake needs to consider water conservancy diversion performance and pile sinking requirement, should not be less than 100mm, should carry out section model test and confirm, considers between the close-packed pile to set up steel sheet wing section structure, improves water conservancy diversion performance when satisfying the pile foundation interval.
