Embodiment 1

[0037] (1) Build the cofferdam with water-resistant building materials:

[0038] On the ocean shoal, use MU10 cement bricks and M5.0 mortar to build a cofferdam with a length and width of 10 meters, and use M5.0 mortar for internal plastering.

[0039] (2) Preparation of filling slurry:

[0040] The modified phosphogypsum material (fresh phosphogypsum and composite yellow phosphorus slag gelatinized powder) was forced to stir for 7 minutes, and then fresh water with 15% of the dry material weight was added and forced to stir for 10 minutes to obtain the modified phosphogypsum material for land reclamation.

[0041] (3) Preparation of filling body:

[0042] The prepared modified phosphogypsum material for land reclamation is poured into the cofferdam, and the filling body is formed by tamping with a vibrating pump.

[0043] (4) Covering and moisturizing, anti-drying maintenance:

[0044] The filling body is protected from wind and dryness by covering with wet sackcloth and w...

Embodiment 2

[0048] (1) Build the cofferdam with water-resistant building materials:

[0049] On the ocean shoal, use MU10 cement bricks and M5.0 mortar to build a cofferdam with a length and width of 20 meters, and use M5.0 mortar for internal plastering.

[0050] (2) Preparation of filling slurry:

[0051] Preparation of filling slurry: The modified phosphogypsum material (fresh phosphogypsum, water-quenched yellow phosphorus slag, cement) was forced to stir for 3 minutes, and then fresh water with a weight of 11% of the dry material was added for 15 minutes to obtain the modified phosphogypsum for land reclamation. Phosphogypsum material.

[0052] (3) Preparation of filling body:

[0053] The prepared modified phosphogypsum material for land reclamation is poured into the cofferdam, and the filling body is formed by tamping with a vibrating pump.

[0054] (4) Covering and moisturizing, anti-drying maintenance:

[0055] The filling body is protected from wind and drying by covering i...

Embodiment 3

[0059] (1) Build the cofferdam with water-resistant building materials:

[0060] On the ocean shoal, use MU10 cement bricks and M5.0 mortar to build a cofferdam with a length and width of 30 meters, and use M5.0 mortar for internal plastering.

[0061] (2) Preparation of filling slurry:

[0062] Preparation of filling slurry: The modified phosphogypsum material (fresh phosphogypsum, fly ash and cement) was forced to stir for 9 minutes, and then 5% of the dry material weight was added to the fresh water and forced to stir for 10 minutes to obtain the modified phosphogypsum material for land reclamation .

[0063] (3) Preparation of filling body:

[0064] The prepared modified phosphogypsum material for land reclamation is poured into the cofferdam, and the filling body is formed by rolling with a roller.

[0065] (4) Covering and moisturizing, anti-drying maintenance:

[0066] The filling body is protected from wind and dryness by covering it with geotextile and watering it...

Abstract

The invention discloses a construction method for land reclamation with modified phosphorous gypsum material. The method comprises the following steps of (1) constructing a cofferdam by using waterproof building materials; (2) preparing filling slurry; (3) preparing a filling body; (4) performing covering moisture preservation and windproof dry maintenance. The method is convenient, rapid and easy to operate; a cofferdam treatment method, a land reclamation material stirring process control method, a filling body forming construction method and a maintenance control method are improved, the length and the width of the cofferdam are determined, and the stirring mixing time of the materials, the water addition proportion and the water addition stirring time are determined, so that the solidification speed of the modified phosphorous gypsum material after the land reclamation can be remarkably increased, and the construction requirements of a land reclamation project are met.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a construction method for land reclamation with modified phosphogypsum materials. Background technique [0002] According to the internal layout of reclamation projects, land reclamation models can be divided into integral reclamation and discrete reclamation; according to the plane design and implementation of reclamation projects, land reclamation can be divided into The modes are roughly divided into artificial island reclamation, shoreline extrapolation reclamation, and straight reclamation. No matter which land reclamation method is used, it is necessary to prepare land reclamation materials with a certain curing speed. The curing speed of land reclamation materials must meet the progress of land reclamation projects, which is crucial to the speed control and effect of project construction. The construction method of land reclamation materials also has a certain influence...
