Abstract

The invention discloses a deep anchor pull pile supporting system. The deep anchor pull pile supporting system comprises anchor rope piles and anchor piles arranged on the sides, away from a foundation pit, of the anchor rope piles, first anchor ropes A and second anchor ropes A are arranged between the anchor rope piles and the anchor piles; an inner row anchor rope surrounding purlin A is arranged on the inner sides of the anchor rope piles; an outer row anchor rope surrounding purlin is arranged on the outer sides of the tops of the anchor piles; one end of each first anchor rope A penetrates through the corresponding anchor rope pile and then is connected to the inner row anchor rope surrounding purlin A, and the other end of each first anchor rope A extends upwards in the inclined direction, penetrates through the corresponding anchor pile and then is connected to the outer row anchor rope surrounding purlin; and one end of each second anchor rope A penetrates through the corresponding anchor rope pile and then is connected to the inner row anchor rope surrounding purlin A, and the other end of each second anchor rope A extends downwards in the inclined direction and is connected to the corresponding anchor pile. The invention further discloses a construction method of the deep anchor pull pile supporting system. The deep anchor pull pile supporting system and the construction method thereof can be carried out within a limited construction range and can improve construction efficiency.

Description

technical field [0001] The invention relates to a support system and a construction method of a deep anchored pile. Background technique [0002] With the rapid development of new urbanization in the country, foundation pit engineering has become an important part of construction engineering, municipal engineering and rail transit engineering. Due to the increasing building density in the city, traffic congestion, narrow site, and poor choice of geological conditions, it is very common for deep foundation pits to be adjacent to existing buildings, which limits the choice of deep foundation pit support types. The supporting structure of piles plus internal support and the support structure of pile wall plus internal support can effectively control deformation, but it is inconvenient to dig the soil, the cost is high, and the construction period is long. Support structures such as piles and anchors are convenient for excavation, low in cost, and convenient in construction. Ho...
