Problems solved by technology

[0005] Building construction on a weak bearing layer requires a variety of mechanical equipment (such as pump trucks, muck trucks, cranes, excavators, etc.) to enter the construction site, because the surface bearing capacity of the weak bearing layer is poor, tens or hundreds of tons When mechanical equipment travels on a weak bearing layer, it is easy to cause the walking mechanism (such as wheels or crawlers) to sink due to excessive weight. Once the walking mechanism sinks into the soil, it is difficult for the mechanical equipment to get out of trouble, which is not conducive to the smooth progress of construction

Embodiment 1

[0035] The strengthening method of the construction channel on the weak bearing layer provided in this embodiment is to fill the construction channel 1 on the ground of the weak bearing layer 2 with filler mixed with adhesive and / or curing agent so that the construction channel 1 forms a continuous reinforcement area, Improve the carrying capacity of the construction channel 1 to the construction machine 4 .

[0036] The strengthening method of the construction channel on the weak bearing layer provided in this embodiment uses the rotary jet drill to fill the weak bearing layer 2 of the construction channel 1 on the construction site with filler to form a reinforcement area 3 and carry out the soil mass of the construction channel 1 with the high-pressure rotary jetting method. strengthen. The reinforcement method includes the following steps:

[0037] 1) Preparatory steps: level the construction site, determine the area of ​​the construction passage 1 according to the site c...

Embodiment 2

[0059] The same parts as those in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0060] Compared with Example 1, the strengthening method of foundation pit protection of this example uses the mixing method to fill the weak bearing layer 2 of the construction channel 1 with fillers to strengthen the soil and form a reinforced area 3 . The reinforcement method includes the following steps:

[0061] 1) Preparatory steps: level the construction site, determine the area of ​​the construction passage 1 according to the site construction specifications, and further determine the reinforcement form of the construction passage 1 and the distribution of the drill holes in the reinforcement area 3. Construction channel 1 includes the passage paths of construction machinery around the construction site (such as figure 1 shown in middle A), the passage path of construction machinery in the middle of the construction site (such as figure...

Abstract

The invention discloses a strengthening method of a construction channel on a weak bearing layer. The construction channel on the ground of the weak bearing layer is filled with filler mixed with an adhesive and / or a curing agent to enable the construction channel to form a continuous reinforcing area. According to the strengthening method, the construction channel in the weak bearing layer is reinforced to form the continuous reinforcing area, so that the bearing capacity strength of the construction channel is improved, and a travelling mechanism of a construction machine is prevented from sinking and being trapped. According to the strengthening method, after the adhesive and / or the curing agent are mixed with the soil body, dispersed soil in the soil body is firmly bonded together, thestrength is improved after hardening, and the bearing capacity is enhanced. The strengthening method greatly improves the bearing capacity of the construction channel to the construction machinery, prevents the travelling mechanism of the mechanical equipment on the construction channel from sinking and affecting the normal construction. The method is suitable for strengthening construction channels on weak bearing layers of various soil types, thus creating favorable conditions for construction operation, accelerating construction progress, improving engineering applicability and being easyto be widely applied.

Description

technical field [0001] The invention relates to the field of construction, in particular to a strengthening method for a construction channel on a weak bearing layer. Background technique [0002] my country has a vast territory, and different regions and different climates have had a profound impact on the soil layer and soil quality, resulting in the need to pay special attention to the foundation treatment of the building during building construction. [0003] With the development of industry, the demand for high-rise or super high-rise buildings in cities, especially densely populated cities, is gradually increasing, and high-rise or super high-rise buildings have high requirements for the bearing capacity of the foundation. If the bearing capacity of the building foundation is not enough, such as the soil foundation with a lot of loose soil, various construction measures are required to strengthen the foundation to minimize the impact of the loose soil. [0004] Accord...
