Embodiment Construction

[0024] The key to the implementation of the caisson wharf lightweight method is to replace the stones backfilled after the caisson and the sand filled in the caisson cavity with light soil. Taking the construction of a certain wharf as an example to describe the lightweight chemical method of the caisson type wharf.

[0025] 1). The silt in the caisson 2 and the backfill 4 of the caisson is sucked out at the berth of the wharf;

[0026] 2). Send the suctioned silt to the rear site to add cement and plastic foam to stir into lightweight soil materials; the foam agent materials are lightweight agents such as plastic foam and waste tires. The weight of light soil for underwater filling shall not be less than 1.0g / cm 3 .

[0027] 3). Level the base layer 8 at the bottom of the caisson 2, float and install the caisson 2;

[0028] 4). After the caisson 2 is installed, throw and fill the light soil behind the caisson 2, and fill the light soil formed by stirring in the empty stoma...

Abstract

A method for lightening port caisson includes the following steps: 1. lift out the caisson and move out sullage filled in; 2. blend sullage moved out with cement and vesicant to form a light-weight filling material; 3. smooth the base of caisson and put back the caisson; 4. fill in the light-weight material to the back of the caisson, as well as in the caisson and press solid; 5. install other parts to the port.

Description

technical field [0001] The invention relates to a design method of a wharf structure, belonging to the technical fields of port engineering and water conservancy engineering. technical background [0002] The caisson gravity wharf is a kind of gravity wharf structure, and the wharf wall adopts the caisson structure type. The traditional caisson-type wharf relies on the weight of the caisson and the bearing capacity of the foundation at the bottom of the caisson to maintain the stability and function of the caisson and the docking structure. [0003] Most of the wharf caissons in my country are made of steel materials or reinforced concrete with thin walls, fasting and bottomed structures. After the caissons are installed on site, sand materials that meet certain requirements are filled in the fasting caissons. Or blown sand. In order to resist the horizontal load of the backfill of the box and the action of the dynamic load, the bottom of the caisson should have sufficient ...
