Construction method of horizontal counter-pulled anchor cable

Abstract

The invention relates to a construction method of a horizontal counter-pulled anchor cable. The construction method comprises the steps that 1, supporting structures of two adjacent foundation pits to be excavated are constructed, and then the first corresponding supporting structure and the second corresponding supporting structure are formed on the adjacent sides of the two foundation pits; 2, soil masses in the two foundation pits and soil masses between the first supporting structure and the second supporting structure are excavated till the bottoms reach the preset height, so that gaps in the first supporting structure and the second supporting structure are exposed; 3, a bottom horizontal counter-pulled anchor cable is provided and installed at the positions, with the preset height, of the bottoms, so that the first supporting structure and the second supporting structure are connected in a counter-pulled mode; 4, the soil masses are backfilled between the first supporting structure and the second supporting structure till the above-mentioned preset height is achieved; 5, the horizontal counter-pulled anchor cable is provided and installed at the position with the above-mentioned preset height, so that the first supporting structure and the second supporting structure are connected in a counter-pulled mode; 6, the step 4 and the step 5 are repeatedly conducted till the backfilled soil masses reach the ground elevation; 7, a concrete structural slab is constructed at the position with the ground elevation.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for horizontally pulling anchor cables. Background technique [0002] With the continuous increase of buildings, the development of underground space is increasing. During the construction of underground space buildings, the foundation pit pile anchor support system determines the stability and safety of the building. [0003] refer to figure 1 , shows a schematic structural diagram of a pile-anchor support system for a foundation pit in the prior art. Such as figure 1 As shown, when the foundation pit of the building is being constructed, if a foundation pit 1a needs to be excavated, and the foundation depth of the foundation pit is very deep, the soil around the foundation pit is easy to collapse. In order to ensure the stability of the foundation pit, the The foundation pit 1a must be supported, and a circle of vertical support piles 2a is drilled...
