Abstract

The invention discloses a construction method of an elevator foundation structure. The construction method comprises the following steps that S1, a pit is manufactured; S2, a base cushion layer is manufactured, a plurality of positioning rings are placed on the pit, and plain concrete is poured; S3, an elevator foundation pit is manufactured, a steel bar assembly is prefabricated, pile head anchoring steel bars are connected, concrete is poured on the steel bar assembly to form a concrete pouring entity, and soil around the concrete pouring entity is backfilled and tamped; S4, foundation pileconstruction equipment is installed, and the foundation pile construction equipment presses down the foundation pile to a bearing stratum; and S5, the foundation pile construction equipment is dismantled, concrete is poured above the foundation piles for fixing, and the elevator foundation structure is formed. According to the construction method, after the elevator foundation pit is manufactured,soil is backfilled and tamped, and the occupied area of a construction site is reduced to the maximum extent; the foundation pile construction equipment is arranged on the concrete pouring entity, sothat other places are prevented from being occupied; and the construction method is simple and rapid in operation step, short in construction period and high in quality reliability.

Description

technical field

[0001] The invention relates to the technical field of elevators, in particular to a construction method for an elevator basic structure. Background technique

[0002] With the development of elevator technology, in recent years, there has been a large number of engineering needs for adding elevators to old buildings. Before installing elevators in these buildings without elevators, it is necessary to construct an elevator infrastructure independent of the original building structure. The elevator foundation structure mainly includes the elevator foundation pit and foundation piles. Since most of the construction sites for installing elevators are inside residential areas, the roads in residential areas are narrow and large-scale construction equipment is often unable to enter.

[0003] However, the mud discharged during the construction of the bored piles pollutes and damages the surrounding environment of the residential area. At the same time, this wet co...

Embodiment Construction

[0035] This part will describe the specific embodiment of the present invention in detail, and the preferred embodiment of the present invention is shown in the accompanying drawings. Each technical feature and overall technical solution of the invention, but it should not be understood as a limitation on the protection scope of the present invention.

[0036] see Figure 1 to Figure 7 , a construction method for an elevator infrastructure, comprising the following steps:

[0037] S1: Make pit 1, excavate pit 1 according to the size of the elevator foundation pit, and then level the bottom surface of pit 1;

[0038] S2: Make the base cushion 3, place a number of positioning rings 2 corresponding to the foundation piles 0 on the bottom surface of the pit 1, and then pour plain concrete on the pit 1 to form a base cushion that fixes the positioning ring 2 3;

[0039]S3: To make the elevator foundation pit, prefabricate the steel bar assembly 4 that is compatible with the foun...
