The whole process of refined construction of prestressed bridges mainly includes seven aspects: pile foundation, pedestal, column, cap beam, precast slab, beam-slab, and bridge deck. 1. Fine construction of bored…
During the pouring process of bored cast-in-place piles, the steel cage often floats up. In mild cases, the steel cage may float up by a few centimeters to tens of…
Pile foundations are widely used due to their high bearing capacity, good stability, small settlement and differential deformation, fast and stable settlement, strong seismic performance, and adaptability to various complex…
The rotary full casing construction method is also known as the "BUROTO" method. The steel casing is used to protect the wall during the hole-forming process. It has the characteristics…
According to the characteristics of the pile and the vertical force, the pile foundation can be divided into two categories: friction pile and end-bearing pile. In construction, only by fully…
1. Common problems During the construction process, bored piles are subject to natural conditions such as technology and strata, as well as management conditions such as process arrangement and management…
1. Common quality problems during construction (1) Pipe blockage: This manifests as concrete blocking the pumping pipeline or drill pipe during the concrete pouring process. There are many reasons for…
1. The Drilling Methods and Principles Can Be Divided into the Following Categories: Spiral drilling, positive circulation rotary drilling, reverse circulation rotary drilling, submersible drilling, punching drilling, impact drilling, and…
1.1 Construction Layout Before the construction layout, the measurement points provided by the design shall be reviewed, the plane control network and the elevation control network shall be re-measured, and…
1, General requirements 1. The location of the steel sheet piles should meet the design requirements and facilitate the construction of the trench foundation, that is, leave room for formwork…
At present, rotary drilling rigs have become one of the mainstream construction machinery for bored piles due to their advanced technology, fast and stable hole formation, and other advantages. Due…
Rotary drilling rigs can be divided into four drilling methods according to geological conditions: cutting, crushing, turning, and grinding. 1. Cutting type: Cutting drilling uses bucket teeth, double-bottom sand buckets,…
