Embodiment Construction

[0017] In order to make the technical features of the present invention more comprehensible, specific embodiments are given below in conjunction with the accompanying drawings to further describe the present invention.

[0018] See figure 1 , which is a flow chart of a construction method for reverse construction of interlayers on soft soil foundations provided by an embodiment of the present invention.

[0019] This construction method comprises the following steps:

[0020] Step S110: setting up an underground structure enclosure in the required construction site;

[0021] Step S120: Carry out earthwork excavation, excavate the soil to the bottom of the first floor slab, then pour concrete for the top structural slab of the first underground floor, and leave an excavation hole on the top structural slab surface of the first underground floor;

[0022] Step S130: According to the position of the excavation hole reserved on the top structural slab of the first underground fl...

Abstract

The invention discloses a method for constructing a soft soil foundation reverse interlayer, which comprises the following steps of: 1. setting an underground enclosing structure in a field to be constructed; 2. carrying out soil excavation, excavating soil to the bottom of a first-floor plate and carrying out the construction of a top-floor structure plate of an underground first floor; 3. carrying out soil excavation, excavating soil to an underground second floor base plate and carrying out the construction of a top-floor structure plate of an underground third floor; 4. by utilizing the maintenance period of the top-floor structure plate of the underground third floor, constructing the top-floor structure plate of the underground second floor; and 5. after the top-floor structure plate of the underground third floor reaches the design strength, sequentially carrying out the construction of other underground lower floor structures according to the steps 3 and 4. By construction through the constructing method, the construction period and can be effectively shortened, the cost is saved, and the economic benefits and the social competitive force of enterprises are improved.

Description

technical field [0001] The invention relates to the technical field of building construction, and in particular to a construction method for reverse construction of interlayers on soft soil foundations. Background technique [0002] The upside-down method that emerged in the 1980s refers to the construction method of the basement structure from top to bottom. This construction method is generally used in the construction of basement structures. During construction, the basement roof is firstly constructed, and then layer by layer from top to bottom. Excavation of earth for construction of basement structure. In general engineering, artificial reinforcement is required for weak foundations, such as mechanical compaction, replacement of soil cushion, piling, etc. According to this traditional method, not only the project cost is too high, the occupation period is long, but also the hidden dangers of quality are difficult to eradicate, and some complex soft soil foundations ca...
