Description

Technical Field

[0001] The present invention belongs to the field of the structure of berthing members in water transportation engineering wharves, and particularly relates to a support system for precast berthing members of a wharf and a setting method thereof. Background Art

[0002] Most of the concrete berthing members of wharves are precast members, which are installed on site with the assistance of machinery. The overall quality of the berthing members is relatively large, and after installation, they need to be cast and connected with the upper structure to form an integral whole. Therefore, when choosing a support, the safety and accuracy of the installation of the berthing members need to be considered. At the same time, the support structure during installation should be fully utilized to facilitate the upper support.

[0003] Currently, after the existing berthing members are cast and connected with the upper structure to form an integral whole, when removing the entire support system, the I-beams inserted into the berthing members need to be horizontally moved out until the I-beams are separated from the entire member to accelerate the removal speed. During this process, the I-beams are extremely likely to damage the berthing members, which is relatively time-consuming and laborious.

[0004] There is also a structure where a berthing member is provided with a reserved hole, and a cross beam passes through the reserved hole and is supported between two bent frames. The overall size of this cross beam is relatively long, and the installation and removal processes are relatively complicated. Summary of the Invention

A berthing member is arranged on the water-facing side at the front end of the cast-in-place pile, and a pile cap is arranged above it. A longitudinal beam is arranged between the cast-in-place piles on the water-facing side and the other bent-frame cast-in-place piles on the same axis; the longitudinal beams are symmetrically arranged on both sides of the cast-in-place piles, and the two longitudinal beams are fixed and limited by a connecting member; a first cross beam and a second cross beam are respectively arranged on both sides of two adjacent berthing members. The outermost first cross beam is pre-arranged at the cantilever end of the longitudinal beam for positioning the installation of the berthing member, and the second cross beam is arranged on the water-facing side of the berthing member for limiting the installed berthing member; the pile cap is fixed above the second cross beam; the berthing member is fixed at the cantilever end of the longitudinal beam through a hoisting fixing member.

[0063] Step 2.4: The two ends of the positioning cross beam intersect with the longitudinal beams of the adjacent bent frames, and the intersection points are fixed by welding.

[0064] In the third stage, hoist the ship-berthing member. Hoist the ship-berthing member between the cantilever parts of the longitudinal beams and install it on the longitudinal beam according to the pre-set position. The specific steps are as follows:

[0065] Step 3.1: Transport the ship-berthing member to the front of the wharf.

[0066] Step 3.2: Pass a pair of steel bars through the reserved holes of the ship-berthing member in sequence, and weld a steel bar at both ends of the steel bar to prevent the steel bar from slipping during the hoisting process of the ship-berthing member.

[0067] Step 3.3: The hoisting machinery hoists the ship-berthing member between the longitudinal beams, and one side of the ship-berthing member closely adheres to the pre-set positioning cross beam.

[0068] Step 3.4: The hoisting machinery slowly and evenly descends until all four stress points of the steel bar are supported by the longitudinal beam.

[0069] Step 3.5: Add a positioning steel I-beam as a limiting cross beam on the water-facing side of the ship-berthing member to firmly fix the ship-berthing member at the accurate target position.

[0076] In the fifth stage, the superstructure is poured and the support system is removed. After pouring the superstructure and reaching the curing standard, the support structure is removed, which specifically includes the following steps:

[0077] Step 5.1: After the pile caps, longitudinal braces, and transverse braces of the superstructure are poured, form removal is carried out after the form removal strength of the components is qualified.

[0078] Step 5.2: Multiple wire ropes pass through the longitudinal braces, transverse braces, and the support system.

[0079] Step 5.3: Release the longitudinal beam connectors and the steel hoop bolts, and slowly lower the support system using the wire ropes.

[0080] Step 5.4: Remove the steel bars in the holes of the berthing members, and remove the square timbers, cross beams, and longitudinal beams in sequence.

[0081] The above embodiments are only described as an example. Different support materials can be selected according to specific working conditions, but all stiffeners, support systems, etc. need to be calculated for stress.
