Supporting structure combining anti-seepage structure and underground diaphragm wall and construction method thereof

Abstract

The invention relates to a supporting structure combining an anti-seepage structure and an underground diaphragm wall and a construction method thereof. The supporting structure comprises an underground diaphragm wall pre-grooved section, a pre-grooved section anti-seepage structure welded on a pre-grooved section reinforcement cage, an underground diaphragm wall post-grooved section and a post-grooved section anti-seepage structure welded on a post-grooved section reinforcement cage, and a lock catch, a bolt and a geomembrane are arranged between the pre-grooved section anti-seepage structureand the post-grooved section anti-seepage structure. According to the supporting structure, the anti-seepage structure is high in deformation capacity, the tensile force of an anti-seepage film is high, the application range of a soil layer is wide, and the mode of combining the geomembrane and the underground diaphragm wall can be used for stopping water at the joint in a deep foundation pit andcan also be used for soil remediation, pollution source isolation and other occasions.

Description

technical field [0001] The invention relates to a supporting structure combined with an anti-seepage structure and an underground continuous wall and a construction method thereof, which is applicable to the fields of foundation pit support, anti-seepage engineering and pollution control. Background technique [0002] With the development of urbanization and industrialization in our country, while pursuing rapid development, the problem of pollution is also becoming more and more serious. As a water interception, seepage prevention, load bearing and soil retaining structure, the underground diaphragm wall is widely used in deep and large foundation pits and pollution control. The underground diaphragm wall has small vibration and low noise during construction, and the wall has high rigidity and can withstand large soil Pressure, good anti-seepage performance, suitable for a variety of foundation conditions. The underground diaphragm wall is applicable to a wide range of fou...

Problems solved by technology

[0003] Traditional construction methods still have shortcomings: high cost, not economical enough

[0008] However, the above method has complex structure, many construction techniques, and difficult to guarantee the construction quality. At the same time, it requires more additional materials during construction, so it is not suitable for large-scale promotion and use under various conditions.
