Anchor cable construction method in steel sheet pile slope protection area

Abstract

The invention relates to the technical field of anchor cable construction after steel sheet pile slope protection in foundation pit engineering, and discloses an anchor cable construction method in a steel sheet pile slope protection area. The anchor cable construction method comprises the following construction steps that S1, construction preparation is conducted; S2, a foundation pit support structure and steel sheet piles are constructed on the ground, during construction, the construction positions of anchor cables are determined, and the steel sheet piles at the positions are short piles; S3, soil body excavation is conducted till the pile top elevation is reached; S4, anchor cable construction is conducted after pile heads are cleaned; S5, after anchor cable construction is completed, top beam construction is conducted; S6, after the strength of the top beam and the strength of the anchor cables meet the requirement, backfilling is conducted on the soil body behind the top beam, and then tensioning and locking are conducted on the anchor cables; S7, the soil in the pit continues to be excavated, a basement structure is constructed after excavation is conducted to the bottom of the pit, and after the basement structure is constructed out of the ground, the soil is backfilled to the ground; and S8, after soil body backfilling is completed, the steel sheet piles are pulled out and recycled. The construction sequence is optimized, so that the construction method better conforms to the conventional construction habits, and the construction smoothness is ensured.

Description

technical field [0001] The invention relates to the technical field of anchor cable construction after steel sheet pile slope protection in foundation pit engineering, in particular to an anchor cable construction method in a steel sheet pile slope protection area. Background technique [0002] Enclosure structure + prestressed anchor cable is a commonly used support structure in the field of civil engineering, especially in slope and foundation pit support. In some cases limited by the site or affected by the surrounding environment, it is necessary to use steel sheet piles for slope protection on the slope above the top surface of the support structure, and then carry out the construction of the foundation pit enclosure structure and anchor cables. In order to ensure the safety and stability of the slope protection of the steel sheet pile, the steel sheet pile needs to be inserted into the soil layer to a certain depth, so the anchorage depth of the steel sheet pile often ...
