Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] The present invention is an improvement on the basis of the existing slope type wharf 1. The existing slope type wharf 1 usually includes a multi-section structure connected in sequence, wherein the first section structure 1-1 is a horizontal section, and in the first section structure The ends of 1-1 are connected in sequence with multiple inclined segments, such as Figure 7 As shown, the inclined section may include two sections, the first inclined section 1-2, the second inclined section 1-3, the intersection angle α between the first inclined section 1-2 and the horizontal plane may be 0<α≤6°, the second The intersection angle β between the two inclined sections and the horizontal plane is basically consistent with the intersection angle α between the first inclined section 1-2 and the horizontal plane.

Abstract

The invention discloses a method for transforming a slope type wharf into a roll-on-roll-off wharf. The method comprises the following steps that S1, the roll-on-roll-off wharf is constructed on the slope type wharf at the lowest water level of the river surface all year round, specifically, an initial steel truss is installed on the front portion of the top face of the head end horizontal section of the slope type wharf, the bottom of the initial steel truss is fixedly connected with the head end horizontal section of the wharf through bolts, the head end horizontal section behind the initial steel truss and a plurality of inclined sections of the slope type wharf are filled with a gravel structure till the top face of the gravel structure and the top face of the initial steel truss are located on the same horizontal plane, first steel plates are laid on the top face of the initial steel truss and the top face of the gravel structure, then, a rubber fender is installed on the front wall of the initial steel truss; S2, equipment is loaded and unloaded; and S3, the height of the wharf is adjusted. By the adoption of the method, segmented transportation of ultra-large equipment is avoided, and the ship unloading efficiency is improved.

Description

technical field [0001] The invention relates to a construction method of a wharf, in particular to a method for transforming an inland river slope type wharf into a temporary roll-on wharf. Background technique [0002] The bulky wharf located in the lower reaches of the Yangtze River is an inland slope type wharf, which cannot use tides for ro-ro unloading, and the unloading operation time is relatively concentrated. This type of wharf unloading method generally adopts the method of manual towing and winching to unload the ship. This method cannot meet the requirements of a large number of equipment, a single piece of equipment with a large weight, and the overall unloading of super-large equipment. Large-scale equipment can only be transported in sections. Unload the ship. [0003] The Chinese patent with the application number 2016103595338 discloses "a component-assembled roll-on wharf structure and installation method", including: support piles, beams, steel cages, pre...
