Problems solved by technology

The combined box-type steel sheet piles on the dock wall usually adopt simple and traditional hammering pile sinking construction technology, which cannot achieve the desired effect on the positioning, appearance and water-stop of the combined box-type steel sheet piles
[0003] At present, there is no system that can guide, control the pile sinking rate, operate easily and ensure the correct pile position, and at the same time have a convenient construction method for correcting deviation during the pile sinking process

Embodiment Construction

[0019] Combine below Figure 1-Figure 5 A specific embodiment of the present invention will be described in detail.

[0020] A construction method for combined box-type steel sheet piles on dock walls, comprising the following steps:

[0021] Step 1. Fix the guide frame, insert the steel sheet piles in the guide frame, position according to the guide frame when inserting piles, form a screen-type pile insertion, and use the interval reverse jumping method when sending piles;

[0022] Step 2. After the insertion of a group of steel sheet piles within the length of the guide frame is completed, insert the first pile of the next group close to the last steel sheet pile, so that the part of the first pile remains on the ground as a For the positioning piles of the last group of steel sheet piles, remove the guide frame;

[0023] Step 3, using the first pile as a spacer pile and then fixing the second guide frame, inserting steel sheet piles in the second guide frame, and repeati...

Abstract

The invention supplies a boatyard dock wall combination type steel sheet piling construction method that includes the following steps: fixing guiding frame, inserting pile into the frame and locating to form folding screen type pitching of pile; after one group pile pitching, pitching the first pile of the next group next to the last pile to make part of the first pile on ground being used as the location pile and removing guiding frame; fixing the second guiding frame according to the first pile, and taking steel sheet piling, repeating the process. The invention could make the appearance of the combination type steel sheet piling flat and water seal.

Description

technical field [0001] The invention relates to a construction method for a combined box-type steel sheet pile, in particular to a construction method for a combined box-type steel sheet pile on a dock wall. Background technique [0002] Since the 1990s, most of the dock walls have adopted high-pile cap single-anchor steel sheet piles, which are also used as water-stop wall structures. The steel sheet piles also serve as enclosure structures during construction and permanent dock wall structures. The combined box-type steel sheet piles on the dock wall usually adopt simple and traditional hammering pile sinking construction technology, which cannot achieve the desired effect on the positioning, appearance and water-stop of the combined box-type steel sheet piles. [0003] At present, there is no system that can guide, control the pile sinking rate, is easy to operate and can ensure the correct pile position, and has a convenient construction method for correcting deviation d...
