Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following defects: when the existing wharf breast wall pipe gallery is being constructed, each group of formwork is erected in sequence, and the process of formwork erection is time-consuming. The tidal re-work restricts the progress of the construction process and prolongs the entire construction period, so there is room for improvement

Embodiment 1

[0048] The embodiment of the present application discloses a formwork structure for a parapet wall pipe gallery of a wharf. refer to figure 1 , several groups of prefabricated caissons 3 are installed on the seabed, each group of caissons 3 is a cuboid, each group of caissons 3 abuts head to tail along its length direction, the extension direction of each group of caissons 3 is perpendicular to the coastline, and the interior of each group of caissons 3 is thrown The upper surface of the caisson 3 is troweled, and the upper surface of the concrete mortar is lower than the plane where the edges of the upper end of the caisson 3 are located. The formwork 1 structure of the breast wall pipe gallery 4 of the wharf includes four sets of formworks 1, and each set of formworks 1 is a prefabricated structure; the upper edge of each set of formworks 1 is welded and fixed with a fence.

[0049] refer to figure 1 and figure 2 The template 1 includes several groups of brackets 12 and ...

Embodiment 2

[0058] A construction method for the breast wall pipe gallery of a wharf, referring to Figure 4 and Figure 5 :

[0059] a. The caissons 3 are hoisted successively to the seabed by means of hoisting equipment, the upper end faces of the caissons 3 of each group are set horizontally, stones are poured into the caissons 3 of each group and underwater concrete mortar is poured;

[0060] b. Place each group of stools 2112 on the upper end surface of the caisson 3, each group of stools 2112 is located on the same straight line, a group of mandrel 2 arranges two groups of stools 2112 collinearly arranged, and then each group of pads 23 are laid on each group The upper end surface of the stool 2112; and the inner molds 21 of each group are installed, and the flat plate 2111 on the second plate 211 of each group abuts against the upper end surface of the spacer 23;

[0061] c. Each group of formwork 1 is prefabricated according to the size of the caisson 3, and each group of formwo...

Abstract

The invention relates to a wharf breast wall pipe gallery formwork structure and a construction method. The wharf breast wall pipe gallery formwork structure comprises four sets of integrally-fixed formworks and a plurality of sets of core formworks; a plurality of sets of caissons are hoisted on a seabed; each set of formwork comprises a plate and a support; the lower end edges of the supports are attached to the caissons and fixedly connected with the caissons; the vertical edges of every two adjacent sets of formworks are attached to each other and fixedly connected with each other; the core formworks are erected on the upper end faces of the caissons; the extending direction of the core formworks is perpendicular to the coastline; each core formwork comprises an inner formwork body and an outer formwork body covering the upper end of the inner formwork body in a sealed mode; the two ends of each inner formwork body and the two ends of each outer formwork body abut against the formworks in a sealed mode; and a closed space is formed by the inner formwork bodies, the outer formwork bodies and the sets of formworks on the two sides, and concrete sand is poured into the closed space. The wharf breast wall pipe gallery formwork structure can meet the tide-rushing operation requirement to the maximum extent, and the operation time of wharf breast wall pipe gallery construction is shortened; and compared with an existing wharf breast wall pipe gallery construction process, the wharf breast wall pipe gallery formwork structure can complete installation operation within a low-tide operation time, the construction speed is high, and the construction time is saved.

Description

technical field [0001] The application relates to the field of wharf pipe gallery, in particular to a formwork structure and construction method of a wharf parapet pipe gallery. Background technique [0002] An oil port refers to a port dedicated to loading and unloading crude oil or refined oil. In order to prevent pollution and safety, the oil port should have a certain safe distance from towns, general ports and other fixed buildings, and it is usually advisable to arrange it downstream and downwind. As modern offshore oil tankers are getting bigger and bigger, modern offshore oil ports are also developing towards deep water. [0003] In the construction process of the oil port wharf, it is necessary to build the breast wall of the wharf, which is a reinforced concrete structure. The construction of the gallery, each group of pipe gallery is used to unload the cruise ship and supplement the fresh water resources during the ocean voyage of the cruise ship. The construct...
