Problems solved by technology

Under this geological condition, the commonly used composite foundation treatment methods, such as dynamic compaction method, deep mixing method, CFG pile, compaction pile, etc., although the bearing capacity of the foundation has been improved to a certain extent after treatment, due to the weak subsurface The depth of the soil layer is different, and the above methods adopt a fixed treatment method, resulting in a certain difference in the strength and deformation of each layer of weak soil, which will cause uneven settlement of the foundation under the long-term action of the upper load , resulting in quality problems such as cracking of the building wall

Embodiment Construction

[0030]In the embodiment shown in FIG. 1 , the foundation soil for construction is a newly filled soil layer or a weak undisturbed soil layer. According to the construction method for strengthening the foundation of the present invention, as shown in Figure 1a, firstly, the rammer 1 is used to free fall to do work to punch and expand to form pile holes, and the hole can also be formed by hammering and following the pipe. As shown in Figure 1b, the hammer punches and expands to a certain depth in the hole, and the hole forming depth should meet the above design value. As shown in Figure 1c, fill the above hole with reinforcement material 2, such as construction waste, gravel, and muck, and make the rammer 1 move along the hole wall to ram the filled reinforcement material, and finally under the action of equal energy The deformation of a blow should meet the design value and form the first compact layer. As shown in Fig. 1d, according to the formation method of the first compac...

Abstract

A method for consolidating foundation features that the fastly releasing winder, cable and heavy hammer are used to punch on soft foundation to form holes, and filling the filler in the holes while ramming them layer by layer.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to foundation reinforcement treatment. Background technique [0002] In the foundation reinforcement treatment of buildings, such geological conditions are often encountered: the building is located on the newly filled soil layer or the weak undisturbed soil layer (hereinafter referred to as the weak soil layer), and the bearing capacity of the weak soil layer is low, which cannot meet the requirements. The requirements of the upper load and deformation, but there is undisturbed soil that meets the strength and deformation requirements of the upper load at a certain depth under the soft soil layer, and in most cases, the depth of the filling layer is different due to geological changes. Under this geological condition, the commonly used composite foundation treatment methods, such as dynamic compaction method, deep mixing method, CFG pile, compaction pile, etc., although the bearing...
