Embodiment Construction
[0031] Referring to the accompanying drawings, a construction method for seamlessly connecting basement exterior walls and retaining piles, the construction steps include:
[0032] 1) Construction of retaining piles
[0033] Stake out according to the dimensions of the retaining piles given in the construction drawings, and construct the retaining piles;
[0034] 2) spray anchor
[0035] Bind the reinforcement mesh on the inner soil of the foundation pit, and spray cement mortar, so that the soil inside the foundation pit forms a wall surface, and the diameter of the reinforcement used for the reinforcement mesh must be >14mm;
[0036] 3) Wall leveling
[0037] In the follow-up construction, the enclosure system will be used as a formwork, so the wall surface should be leveled to ensure the flatness;
[0038] 4) Drain setting
[0039] Carry out drainage hole construction on the enclosure piles according to the design requirements. After the construction is completed, the d...

The invention discloses a seamless connecting construction method for a basement outer wall and fender piles. The method comprises the following steps: finishing construction of the fender piles; binding reinforcing mesh sheets on the inner-side soil body of a foundation pit; jetting cement slurry to form a wall surface by the inner side soil body of the foundation pit; performing drainage arrangement on the fender piles, and treating the pile bodies; performing water-proofing treatment on an enclosure system; arranging vertical steel bars, horizontal steel bars and stirrups on the basement outer wall; supporting a template on the inner side of the basement outer wall to form a single-side support system with the inner-side soil body of the foundation pit; casting concrete; removing the template when the design strength requirement of the basement outer wall is met. According to the construction method, the inner-side wall surface of the foundation pit is directly taken as one side template of the basement outer wall, and only the inner-side template of the basement outer wall needs to be supported on a construction field to construct the single-side supporting system together with the inner-side wall surface of the foundation pit, so that one construction procedure is eliminated, the manual workload is lowered, the construction time is saved, the construction efficiency is increased, and the consumption of template materials is lowered; seamless construction is adopted for the basement outer wall and the enclosure system, so that heat-preserving treatment between the outer wall and the enclosure system is not needed compared with the prior art.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a construction method for seamless connection of basement exterior walls and surrounding protection piles. Background technique [0002] The existing basement exterior wall construction method is usually to stake out the dimension boundary line of the basement exterior wall after the construction of the enclosure structure is completed, arrange the steel bars of the basement exterior wall, support the formwork, pour the basement exterior wall concrete, and wait for the concrete to reach the design strength. Remove formwork when required. This kind of process wastes templates, requires a large amount of labor, takes a long time to construct, and wastes a lot of building space for the enclosure system. Contents of the invention [0003] The object of the present invention is to provide a construction method for seamless connection between basement exterior walls and retainin...
