The actual construction comprises the following steps:

the first step is as follows: cleaning and polishing stone

And (5) cleaning the riprap at the construction position of the wharf by adopting an excavator.

The second step is that: lowering of berthing piles 1 and construction of waist rails

The berthing ship pile 1 is manufactured by processing thick steel plates with the thickness of more than 10mm, the berthing ship pile 1 is put down while excavating the foundation pit, when 2 berthing ship piles 1 are hung, the periphery of the berthing ship pile 1 needs to be backfilled by broken stones and filled, after one berthing ship pile 1 is placed, the queen turning block 4 is regularly stacked on the outer side immediately, and after the berthing ship pile 1 is embedded, the berth ship pile 1 is manufactured by processing thick steel plates with the thickness of more than 10mmThe outer side of the berthing pile 1 is transversely welded with double-spliced HN 500X 200 type steel wale (comprising a first wale 7 and a second wale 9) for connection, so that the berthing pile 1 can be integrally connected on one hand, and the berthing pile 1 can be ensured to be on the same horizontal line on the other hand. Additionally welded in the longitudinal and transverse directions

The other end of the horizontal pull rod 8 is pre-buried in the back of C30 for fixing, and the distance is 1 m. The double-spliced HN 500X 200 section steel waist beam is provided with ribbed plates at equal intervals on the inner side, the ribbed plates are made of 8mm Q235 steel, the local rigidity of the section steel is increased, and the intervals are consistent with the arrangement intervals of the pull rods.

The third step: and (3) pouring concrete in the berthing pile 1.

After the berthing piles 1 are placed, immediately pouring concrete inside the berthing piles, adopting C30 concrete, pre-burying 3 PVC pipes with the diameter of 60mm in each berthing pile 1 before pouring to serve as grouting holes of the vertical pull rod 6, wherein the height of each PVC pipe is at least 70cm higher than the surface of the protection cylinder. The concrete is delivered into the mould by a crane and distributed in layers. When pouring, the straightness and the plane position of the pile are controlled by using a measuring instrument, and before pouring, 5 piles are pre-embedded on a single ship-leaning pile 1

The reinforcing steel bar is connected with the crown beam 3.

The fourth step: and backfilling the sandstone 5 at one time.

After the sandstone 5 is transported to the site, an excavator is adopted to cooperate with a dump truck to transport the material. Unloading and paving are carried out simultaneously, and a high-power bulldozer is adopted for forward paving. And (4) rolling by using a smooth road roller, wherein specific rolling parameters are determined on site. The corner of the structure is not easy to be compacted by a rolling machine and is compacted by a small-sized tamping machine. And the sand stone 5 is rolled in layers in the backfilling process, and the rolling thickness of each layer is not more than 30cm, so that the backfilling is guaranteed to be compact. The once backfilling thickness is slightly lower than the pre-buried height positions of the transverse pull rod 8 and the longitudinal pull rod 10, and the backfilling can be continued after the construction of the transverse pull rod 8 and the longitudinal pull rod 10 is completed and the designed elevation is reached. And thin steel plates with equal length are welded on the inner side and the outer side of the ship-leaning pile 1, the bottom is ensured to be embedded into the filling soil, cement paste is poured on the inner side of the ship-leaning pile 1 for reinforcement after the installation is finished, and the filling soil and the rockfill loss caused by seawater scouring are prevented.

The fifth step: anchorage 2 construction

And completing the construction of the anchorage 2 while backfilling the gravel 5. The anchor 2 is made of C30 concrete, the integral anchor is embedded into a part of the flakelite, and the rest part of the integral anchor is embedded into the sandstone 5. In the construction process of the anchorage 2, the transverse pull rod 8 connected with the first waist beam 7 penetrates through the anchorage 2 to be embedded, and the anchorage 2, the horizontal pull rod 2 and the ship leaning pile 11 are ensured to be tensioned.

And a sixth step: the transverse pull rod 8 and the longitudinal pull rod 10 are constructed.

The transverse pull rod 8 and the longitudinal pull rod 10 adopt

The finish-rolled deformed steel bar of (2) has a length of not less than 15 m. During construction, firstly, a waist beam is perforated according to a gap between ship-leaning piles 1, the hole position is phi 40, and then a transverse pull rod 8 and a longitudinal pull rod 10 are connected with the waist beam and then are screwed and fixed by using steel gaskets and bolts; when the other end is constructed by the anchorage 2, the transverse pull rod 8 is buried in the anchorage 2, and the part protruding out of the front end of the anchorage 2 is fixed by a steel gasket and a bolt, so that the anchoring capability is enhanced.

The seventh step: construction of crown beam 3

The method is characterized in that a crown beam 3 is arranged at the concrete top position of a berthing pile 1, the cross section size of the crown beam is 130cm multiplied by 60cm, the length is determined according to the actual size on site, a hinged bracket 11 is arranged on the inner side of the crown beam 3, and the position of the crown beam 3 is 10cm inward offset of the outer edge of the berthing pile 1.

Eighth step: secondary backfilling sandstone 5

And after the construction of the crown beam 3 is finished, carrying out secondary backfilling on the foundation immediately, and backfilling to the designed elevation position.

The ninth step: vertical pull rod 6 drilling construction

Arranging a drilling machine in place according to the embedded hole position in the berthing pile 1, adjusting the drilling angle of a drill rod, wherein the depth of an anchor hole is at least 12m, and immediately inserting the vertical pull rod 6 after drilling.

The tenth step: grouting

In the grouting process, the grouting pipe is slowly drawn out from the bottom of the hole, grouting can be stopped when the hole emits grout for more than 10 seconds and is stable, and in order to ensure that the vertical pull rod 5 is tightly combined with the surrounding soil body, a grout stop plug is arranged at the hole and is screwed.

The eleventh step: tensioning and anchor sealing

The tensioning equipment is selected according to the material of the vertical pull rod 6 and the size of the locking force. And after the concrete in the ship-leaning pile 1 reaches the strength and the slurry strength of the anchoring section reaches the designed strength, tensioning can be carried out. After tensioning and locking are finished, cutting off redundant vertical pull rods 6 by using a grinding wheel cutting machine, coating the anchorage and the exposed vertical pull rods 6 by using epoxy resin, and chiseling and washing the concrete around the anchorage before sealing.

The twelfth step: construction panel 12
