Embodiment Construction

[0027] The present invention is described in detail below in conjunction with accompanying drawing:

[0028] Such as figure 1 As shown, the support system of the construction method of the present invention is mainly composed of main structure 1, support pile 2, horizontal support 3, support frame 4, support purlin 5, and vertical steel row 7. The construction method of the present invention is carried out according to the following steps:

[0029] First construct the main structure 1 separated by a certain distance from the support piles of the foundation pit 10, such as figure 2 As shown, part of the earthwork 8 is reserved to balance the lateral soil pressure transmitted by the support pile 2, and the post-pouring belt 1.1 and the structural opening are treated during the construction of the main structure 1, as shown in image 3 As shown, for the post-construction pouring belt 1.1, the pre-embedded angle steel 1.2 is 700 mm, the embedded concrete on both sides is 500 mm,...

Abstract

The invention relates to a support change construction building method implemented by using a main structure of a building, which is characterized in that a foundation pit support is respectively supported on a foundation pit support pile and a beam slab of the main structure of the building by using the two ends of a steel supporting member, one end of the steel supporting member is connected with the structure beam slab through a steel waling and a steel soldier pile, and parts of a post-cast strip, a tunnel opening and a ramp are respectively provided with a steel-structure load-transfer member, thereby achieving a supporting effect on foundation pits; and under the action of supporting, the main structure between the foundation pit support pile and a finished structure is constructed. According to the method disclosed by the invention, the appropriate parts of the post-cast strip, the tunnel opening and the ramp of the structure are respectively provided with a reliable load-transfer member, so that a situation that in the process of support change construction, the main structure of the building is not damaged is ensured, wherein, the post-cast strip is provided with a rebar as the load-transfer member, and the tunnel opening and the ramp are respectively provided with a temporary floor; by using the building method, the safety of the foundation pit support can be effectively ensured, the deformation of the ground and the supporting pile can be effectively controlled, and the difficulty of engineering construction can be reduced; and the building method is rapid in construction progress, low in construction cost and high in engineering quality.

Description

technical field [0001] The invention relates to a construction method of using the main structure of the building to support the foundation pit and replace the support construction. The main structure of the building is used to adjust and redistribute the lateral soil pressure of the supporting piles to ensure the safety and reliability of the foundation pit construction, especially It is a support replacement construction with strict requirements on foundation pit support piles and ground deformation in severe cold areas. Background technique [0002] Since the use of anchor rods is currently restricted during the support construction of deep foundation pits to avoid damage to surrounding buildings, the current support method commonly used for deep foundation pits is to form an enclosure structure with pile walls combined with internal supports. The support system consists of purlins, horizontal The support and column are composed of three parts. The horizontal support is s...
