Adjustable intelligent impacting and rolling combined reinforcing method

Abstract

The invention belongs to the technical field of large-area dynamic compaction replacement foundation treatment in constructional engineering, and particularly relates to an adjustable intelligent impacting and rolling combined reinforcing method. The reinforcing method comprises the following steps: S100, field leveling and S200, dynamic compaction replacement treatment are conducted, specifically, in the first step, point compaction construction is conducted, in the compaction process of a replacement hammer, replacement materials are sequentially backfilled into a compaction pit to form replacement pier bodies, point-by-point construction is conducted, regularly-arranged replacement pier bodies and inter-compaction strips are formed, the inter-compaction strips are strips formed by gaps between every two adjacent rows of replacement pier bodies, after construction is completed, field leveling is conducted, according to the distance between the replacement pier bodies, the width of a steel wheel of impact rolling equipment is adjusted, and the width of the steel wheel is smaller than that of the inter-compaction strips; S300, impact rolling is conducted through an adjustable intelligent combination method; and S400, a cushion layer is laid. The method solves the problems of high treatment difficulty, long construction period and high post-construction settlement requirement of weak parts among piles, rams and replacement piers, and has the advantages of good treatment effect, multiplied construction speed, small foundation site settlement after completion and the like.

Description

technical field [0001] The invention belongs to the technical field of large-area dynamic compaction replacement foundation treatment in construction engineering, and in particular relates to an adjustable intelligent punching-rolling combined reinforcement method. Background technique [0002] In engineering construction, the disadvantage of using various types of piles, dynamic ramming, dynamic ramming replacement, and semi-replacement construction is that there has been no efficient treatment method for the soil between piles and ramming, especially in dynamic ramming and dynamic ramming replacement. , affected by the diameter of the rammer, the traditional full ramming method not only takes time and effort, affects the construction period, but also cannot fully deal with this part when dealing with the replacement of the weak strip between the pier and the rammer. Interstitial soil and surface shallow soil have always been difficult problems in this type of project. Affe...

[0002] In engineering construction, the disadvantage of using various types of piles, dynamic ramming, dynamic ramming replacement, and semi-replacement construction is that there has been no efficient treatment method for the soil between piles and ramming, especially in dynamic ramming and dynamic ramming replacement. , affected by the diameter of the rammer, the traditional full ramming method not only takes time and effort, affects the construction period, but also cannot fully deal with this part when dealing with the replacement of the weak strip between the pier and the rammer. Interstitial soil and surface shallow soil have always been difficult problems in this type of project. Affected by this, in the foundation treatment design scheme, silty soil, high saturation silt, soft plastic cohesive soil, and weak underlying layers are encountered. For large-area foundations suitable for dynamic compaction replacement and semi-replacement construction, such as filling soil, various types of piles and other more costly processing methods are often used
