Embodiment

[0024] 1. Construction process

[0025] A construction method for Larsen steel sheet piles, comprising the following steps: baseline determination → pile location → driving of steel sheet piles → measures before earthwork excavation → completion of civil construction → removal of steel sheet piles.

[0026] 2. Main construction technical points

[0027] Inspection, hoisting and stacking of steel sheet piles

[0028] (1) Inspection of steel sheet piles

[0029] For steel sheet piles, there are generally material inspections and appearance inspections in order to correct unqualified steel sheet piles and reduce difficulties in the piling process.

[0030] ① Appearance inspection: including surface defects, length, width, thickness, height, end rectangle ratio, straightness and lock shape, etc.

[0031] Pay attention during inspection:

[0032] a) Welding parts that affect the driving of steel sheet piles shall be cut off;

[0033] b) Reinforcement should be given to cut hol...

Abstract

The invention discloses a construction method of a Larsen steel sheet pile. The construction method comprises the following steps of determining a base line, determining a pile position, driving the steel sheet pile, taking measures before earth excavation, completing civil construction and pulling out the steel sheet pile. The plane arrangement shape of the foundation pit dado steel sheet pile needs to be straight and tidy as much as possible, irregular corners are avoided, and utilization and supporting arrangement of standard steel sheet piles are facilitated. All peripheral sizes accord with the sheet pile modulus as much as possible. During the whole construction period, in the construction operations of earth cutting, hoisting, reinforcing steel bar tying, concrete pouring and the like, collision of the support is strictly prohibited, the support is prohibited from being dismantled at will, cutting and electric welding on the support are prohibited at will, and heavy objects are not required to be placed on the support.

Description

technical field [0001] The invention specifically relates to a construction method of a Larsen steel sheet pile. Background technique [0002] The main mechanical equipment and materials for conventional Larsen steel sheet pile construction are as follows: (1) crawler excavator (modified), hydraulic vibratory hammer, excavator and crane, etc.; (2) material: Larsen steel plate model and steel plate according to design requirements length. After the construction of the main body is completed and the foundation pit is backfilled, the steel sheet piles shall be pulled out for reuse. Before pulling out steel sheet piles, the sequence of pile pulling methods, pile pulling time and soil hole treatment should be carefully studied. Otherwise, the ground settlement and displacement will be caused due to the vibration effect of pile pulling and too much soil in the pulling pile, which will bring harm to the constructed structure. It is very important to try to reduce the amount of s...
