Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a hoistway construction elevator foundation which is simple in structure, convenient to construct, safe and reliable, so as to achieve the purposes of reducing the potential safety hazard of building construction, improving the construction quality, improving the construction environment and reducing the construction cost.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a well construction elevator basis, include the elevartor shaft and arrange the sump pit in elevartor shaft one side, reserve the recess in the bottom of elevartor shaft, it has round brick fetal membrane to build by laying bricks or stones at the corner of recess, it has plain concrete to fill in the space that covers at the brick fetal membrane, pre-buried drain pipe in the bottom of brick fetal membrane, and the drain pipe with the space and the sump pit intercommunication that the brick fetal membrane covers, install the extruded sheet on the lateral wall all around of recess, it has the level to join in marriage the grit to fill in the bottom of recess, the construction elevator foundation concrete has been pour on the level to join in marriage the grit, fixed mounting has construction elevator foundation base on construction elevator foundation concrete.
Further, the construction elevator foundation concrete is provided with two groups of reinforcing bars.
Further, the top surface of the construction elevator foundation concrete is provided with a 2% gradient, and the top surface of the construction elevator foundation concrete is flush with the top of the brick bed film.
Due to the adoption of the technical scheme, the invention has the following advantages:
1. according to the invention, the extruded sheets are arranged around the bottom of the elevator shaft, so that the damage to the main structure during later construction of the elevator foundation is avoided;
2. according to the invention, the drain pipe is arranged in the space enclosed by the brick bed film, the plain concrete is filled in the space enclosed by the brick bed film, and the top surface of the foundation concrete of the construction elevator is provided with a 2% gradient, so that the phenomenon that the drain pipe is damaged due to extrusion of the graded sand stone backfilled in the use process of the construction elevator on the drain pipe is effectively avoided, and the phenomena of unsmooth drainage, accumulated foundation water, loss of graded sand and foundation settlement and the like are avoided;
3. the backfill thickness control of the graded gravel can reduce the cost, and can also adapt to the requirements of different construction elevator models on the height of the elevator foundation and control the relative elevation between the graded gravel and the structural slab.
