Example Embodiment

[0042] Example 1: A fabricated underground continuous wall, refer to figure 1 , Including the installation channel 1 opened on the ground, a number of continuous wall units 2 are placed in sequence in the installation channel 1, and a telescopic assembly 3 is sandwiched between two adjacent continuous wall units 2. The telescopic assembly 3 includes two installations The plate 31 and a telescopic rubber strip 32, and two mounting plates 31 are attached to the opposite side walls of the adjacent continuous wall unit 2. The stretchable rubber strip 32 has elastic force and can produce corresponding changes according to the change of the gap between two adjacent continuous wall units 2 so that the two adjacent continuous wall units 2 are always kept in a filled state.

[0043] Reference figure 1 , The transverse cross-sectional view of the mounting plate 31 is a "U" shape, the opening of the mounting plate 31 faces the telescopic rubber strip 32, and the two sides of the telescopic r...

Example Embodiment

[0048] Embodiment 2: A construction method for fabricated underground continuous walls, the specific steps are as follows:

[0049] S1. Use an excavator to excavate the installation channel 1, and the sidewall of the installation channel 1 is supported by supporting steel bars. When excavating, it should be ensured that the side wall of the installation channel 1 is vertical and the bottom is horizontal;

[0050] S2. Before hoisting the continuous wall unit 2, attach the mounting plate 31 to the continuous wall unit 2. During the installation process, the reinforcement anchor bars 21 should pass through the mounting plate 31, and then strong steel bars 33 are placed vertically in the mounting plate 31 , The joints of the strong steel bar 33 and the reinforced anchor bar 21 are wound and tightened with steel wire;

[0051] S3. After the reinforcement anchor bars 21 and the strong steel bars 33 are installed, the support steel 34 is placed transversely in the mounting plate 31. The su...

Abstract

The invention relates to the technical field of civil engineering and aims at providing a fabricated underground continuous wall and a construction method thereof. The technical scheme of the construction method of the fabricated underground continuous wall is characterized by comprising forming a mounting ditch in the ground, sequentially mounting a plurality of continuous wall units inside the mounting ditch, and clamping extension modules between every two neighboring continuous wall units, wherein every extension module comprises two mounting plates and an extension rubber strip, the extension rubber strip is clamped between the two mounting plates, and the two mounting plates are attached onto the opposite side walls of the corresponding two continuous wall units. According to the construction method of the fabricated underground continuous wall, the extension rubber strips can adapt to thermal expansion and contraction between the continuous wall units to reduce upheaval and depression between the continuous wall units.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an assembled underground diaphragm wall and a construction method thereof. Background technique [0002] Diaphragm wall is the preferred structural form for deep foundation construction and deep foundation pit enclosure, and has been widely used all over the world. At present, the underground diaphragm wall is replacing many traditional deep foundations and deep foundation pit enclosure structures and construction methods. The underground diaphragm wall has little vibration and low noise during construction, and is suitable for construction in densely built urban areas; the wall has high rigidity and good anti-seepage performance; it can be applied to various geological conditions. The underground diaphragm wall can make full use of the limited ground and space within the red line of the building, and give full play to the investment benefits; it has high work efficien...
