Description

TECHNICAL FIELD

[0001] The present application relates to the field of civil engineering and bridge construction, and particularly relates to a construction method for reinforcing an envelope column of a soft soil mixing station. BACKGROUND

[0002] With the rapid development of economic construction, the demand for bridges and various buildings is increasing, and the demand for concrete is also increasing. At the same time, the appearance and quality of the construction process are also improving, which means that the site selection of the concrete mixing station should be close to the construction site. In the meantime, it is also subject to the interference of environmental factors such as climate, geology, and groundwater. The envelope of the concrete mixing station also faces this problem.

[0003] The envelope of the concrete mixing station not only improves the appearance of the mixing station, but also needs to resist the influence of typhoon climate factors. The envelope column is the main load-bearing structure of the mixing building envelope. In soft soil, it is difficult to ensure the bearing capacity required by the mixing building envelope in the form of ordinary foundation, and the construction difficulty is high, and the economic cost is high. In order to ensure the stability, economy, and bearing capacity of the mixing building envelope construction in soft soil, a construction method for reinforcing the envelope column of the soft soil mixing station is needed. SUMMARY

[0004] The purpose of the present application is to provide a construction method for reinforcing the envelope column of the soft soil mixing station, which is simple in construction, high in installation precision, and can effectively reduce the construction difficulty, ensure the construction precision and the stability of the envelope column.

[0005] The purpose of the present application is achieved as follows:

[0006] A construction method for reinforcing the envelope column of the soft soil mixing station, characterized by the following specific steps:

[0007] A. The measurement personnel first preliminarily position a plurality of envelope columns, and lay a layer of concrete in the range of the plurality of envelope columns, while ensuring the flatness of the concrete;

[0008] B. After the concrete reaches the set strength, the measurement personnel use a total station to accurately position and lay out the first envelope column, and use a crane to hoist the envelope column to the designed position. The lower surface of the envelope column is precisely fitted with the concrete, and the envelope column is fixed with expansion bolts. At this time, the crane is not unhooked.

[0009] C. A corbel is arranged between the powder tank support leg steel pipe pile and the envelope column, and is preliminarily reinforced by spot welding. After the crane is unhooked, the reinforcement is continued by supplementary welding.

[0010] D. Repeat steps B and C to complete the installation and construction of the remaining envelope columns and corbels.

[0011] The present application is to set up corbel between powder tank supporting leg steel pipe pile and enveloping column to reinforce, to lay concrete in the area of enveloping column, which mainly plays the role of accurate positioning and preliminary bearing of enveloping column, to set up expansion bolt on the lower surface of enveloping column to play the role of preliminary fixing.

[0012] Compared with the prior art, the present application has the following advantages:

[0013] 1. Laying concrete in the area of enveloping column can accurately position the enveloping column and simultaneously play the role of preliminary bearing;

[0014] 2. Setting up corbel between powder tank supporting leg steel pipe pile and enveloping column to reinforce can increase the overall stability and bearing capacity of the structure;

[0015] 3. The present application can realize the reinforcement construction of enveloping column in soft soil, and has the advantages of simple and smart structure, simple construction, high installation precision, flexible operation, saved materials and simplified construction process.
