Abstract

The invention discloses a supporting and protecting device which comprises multiple steel plate piles, multiple cement agitating piles and I-shaped steel, wherein the multiple cement agitating piles are distributed along the edge of a foundation pit; one end of each cement agitating pile is punched under the ground; hook parts are arranged at two ends of each steel plate pile; the steel plate piles are distributed in the longitudinal and transverse directions, and are in contact with the cement agitating piles; the steel plate piles in the longitudinal and transverse directions are mutually fastened through the hook parts; after the steel plate piles in the longitudinal and transverse directions are mutually fastened, the I-shaped steel is arranged in the hook parts in a sleeving manner. The invention further provides a construction method of the supporting and protecting device. According to the supporting and protecting device, the steel plate piles in the transverse and longitudinal directions are mutually fastened to form a two-row steel plate pile structure, so that the steel plate piles on two sides are restricted to each other, the bearing capacity is high, and stability and reliability are realized; furthermore, the cement agitating piles are arranged in gaps between the two rows of steel plate piles, so that the lateral displacement resistance rigidity of the steel plate piles is effectively improved, and the deformation of the foundation pit is reduced; the steel plate piles and the cement agitating piles can be recycled for reuse, so that the construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a support device and a construction method thereof. Background technique [0002] At present, in the field of construction, the steel sheet piles used as support have strong bearing capacity and light structure, and the continuous wall formed by the steel sheet piles has high strength and rigidity. And the water tightness is good, the joints of the steel sheet piles are tightly combined, which can prevent seepage naturally, and the construction is simple, can adapt to different geological conditions and soil properties, can reduce the amount of excavation of foundation pits, and the advantages of small site occupation for operations, while It is widely used in the entire construction industry, from the use of traditional water conservancy projects and civil crafts through the application of railways and tram tracks to the control of environmental pollution. Howeve...
