Problems solved by technology

[0004] The foundation treatment of sediment treatment plants in soft soil areas usually adopts reinforced concrete structures in the form of sheet piles. However, the current foundation treatment construction method of sediment treatment plants has a large amount of on-site labor and a long construction period, and the structural mechanical properties are greatly affected by the quality of on-site construction. and other defects

Embodiment 1

[0028] A sediment treatment plant is located in a southern city, and the current area is a pond. The total area of ​​the pond is about 82,000 m 2 , the sediment treatment plant covers an area of ​​about 25,500 m 2 . The foundation is heavily loaded by the superstructure and the foundation soil cannot be directly used as a bearing layer. Therefore, pretensioned prestressed high-strength concrete pipe piles (PC piles) are used to reinforce the foundation, including the dehydration workshop in the sediment treatment plant and the gas storage tank pipes. The two areas of the pile foundation project are also an important part of the sediment treatment plant.

[0029] According to the existing survey data, comprehensive regional data and on-site geological survey, there are Quaternary artificial fill layers (Q ml ), Quaternary alluvium (Q al ), Jurassic sedimentary rock (J) argillaceous siltstone, according to its origin and material composition, can be divided into 5 engineering...

Embodiment 2

[0063] A method for constructing a pipe pile foundation for a bottom sludge treatment plant, comprising the following steps:

[0064] (1) Site leveling: clean up various wastes in the pile foundation area, then backfill the foundation to the design elevation, carry out earthwork balance, and level the site to the pile foundation construction requirements;

[0065] (2) On-site setting-out: set multiple control pile pre-leveling points near the piling construction area, and the axis control should be set at a distance of 7-8m from the outer pile to control the axis and elevation of the pile; place the pile positioning line according to the drawing , press outward from the center to form piles to prevent leaks and dislocations; according to the known control points on site, the pile position control points are measured and released according to the pile spacing required by the design;

[0066] (3) Pile driving equipment preparation: move the pile driver to the pile position accor...

Embodiment 3

[0096] A method for constructing a pipe pile foundation for a bottom sludge treatment plant, comprising the following steps:

[0097] (1) Site leveling: clean up various wastes in the pile foundation area, then backfill the foundation to the design elevation, carry out earthwork balance, and level the site to the pile foundation construction requirements;

[0098] (2) On-site setting-out: set multiple control pile pre-leveling points near the piling construction area, and the axis control should be set at a distance of 7-8m from the outer pile to control the axis and elevation of the pile; place the pile positioning line according to the drawing , press outward from the center to form piles to prevent leaks and dislocations; according to the known control points on site, the pile position control points are measured and released according to the pile spacing required by the design;

Abstract

The invention provides a construction method of a pipe pile foundation for a bottom mud treatment plant. The construction method comprises the following steps of (1) site leveling, (2) site paying-off, (3) piling equipment preparation, (4) piling operation, (5) pile cutting treatment, and (6) acceptance inspection. The construction method can be effectively used for meeting the construction requirement of the bottom mud treatment plant, and the problems of safety and stability of the bottom mud treatment plant are solved. The method is advanced, scientific, high in construction speed, easy to operate, good in quality, high in strain resistance, stable and safe.

Description

technical field [0001] The invention belongs to the technical field of pile foundation construction, and in particular relates to a construction method of a pipe pile foundation for a bottom mud treatment plant. Background technique [0002] With the development of modern economy and the progress of society, the scale of buildings has been continuously expanded, and the depth of foundation treatment has also been continuously increased. As a deep foundation, the adoption rate of pile foundation has also been continuously increased. According to incomplete statistics, the annual consumption of piles in my country is more than several million or even more, and pile foundation projects account for 20%-30% of the cost of general civil engineering, and the proportion of foundation treatment in soft soil areas is even higher. Soft soil is widely distributed in my country, and there are many complex soft soil foundations in coastal areas such as the Bohai Bay, the Yellow River Delt...
