Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit pipeline construction, specifically a support device for feeding materials into large-diameter pipelines in deep foundation pits. Background Technology

[0002] Deep foundation pit engineering generally refers to foundation pits with an excavation depth exceeding 5 meters (including 5 meters), or foundation pits with a depth not exceeding 5 meters but with complex geological conditions, surrounding environment, and underground pipelines, or those that affect the safety of adjacent buildings (structures). During the construction of deep foundation pits, horizontal supports are needed to support the sheet pile walls on the inner wall of the deep foundation pit to prevent the foundation pit from collapsing.

[0003] There is a utility model patent with application number 202322853027.2 entitled "A Modular Pipeline Pit Support Device", which discloses a technical solution including multiple sequentially connected anti-seepage pit supports; each anti-seepage pit support includes a support member, a support member, and a sealing member; the support member includes two parallel support plates spaced apart, and each support plate has a connection position at its edge; one end of the support member is connected to one of its support plates, and the other end is connected to the other support plate; the connection positions of the support plates of two adjacent anti-seepage pit supports are connected; the sealing member is located between the connection positions of the support plates of two adjacent anti-seepage pit supports.

[0004] In deep foundation pit engineering, the laying of large-diameter pipelines presents numerous challenges due to the presence of lateral supports within the pit. Traditional construction methods often require significant manpower, resources, and time, and struggle to guarantee efficiency and safety. For instance, in laying a 1600mm diameter heating pipeline in a 4.5m deep foundation pit, existing technologies cannot effectively address the obstruction caused by lateral supports, leading to slow construction progress, increased costs, and potentially adverse effects on the stability of the pit and the quality of pipeline installation. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems and provide a support device for feeding large-diameter pipes in deep foundation pits. When the horizontal supports inside the foundation pit are removed and the pipes are installed, the device can support the inner wall of the foundation pit and prevent the foundation pit from collapsing.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A support device for feeding large-diameter pipes in deep foundation pits includes symmetrically arranged support rods for supporting the two side walls of the foundation pit. One of the support rods is equipped with a lifting mechanism for lifting the cross brace, and the lower end of the support rod is equipped with a positioning mechanism for positioning the pipe.

[0008] One side of the support rod has guide sleeves at both ends, and the other side of the support rod has slide rods at both ends that extend into the guide sleeves and slide within the guide sleeves.

[0009] Furthermore, the lifting mechanism includes a winch mounted on the corresponding support rod, and the end of the wire rope on the winch is provided with a hook.

[0010] Furthermore, a base plate that can move left and right is provided at the lower end of the support rod corresponding to the lifting mechanism.

[0011] Furthermore, the support rod is provided with a bracket, and the winch is mounted on the bracket.

[0012] Furthermore, the positioning mechanism includes a column disposed at the lower end of the support rod, and a baffle is provided at the lower end of the column.

[0013] Furthermore, the support rod is provided with a lifting ring.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model includes symmetrically arranged support rods for supporting the two side walls of a foundation pit. One support rod is equipped with a lifting mechanism for raising the cross brace, and the lower end of the support rod is equipped with a positioning mechanism for positioning the pipe. When the pipe is being placed, the two support rods are respectively supported on the inner walls of both sides of the foundation pit to prevent the pit from collapsing due to the removal of the cross brace. The removed cross brace is lifted at one end by the lifting mechanism, so that the cross brace stands upright on one side of the foundation pit without interfering with the pipe placement. After the pipe is placed to the bottom of the foundation pit, the positioning mechanism positions the pipe, assisting in pipe positioning and facilitating pipe alignment. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0020] like Figure 1 As shown, a support device for feeding large-diameter pipes into deep foundation pits includes symmetrically arranged support rods 1 for supporting the two side walls of the pit. One support rod 1 is equipped with a lifting mechanism for raising the cross brace, and the lower end of the support rod 1 is equipped with a positioning mechanism for positioning the pipe. During pipe feeding, the two support rods 1 are respectively supported on the inner walls of both sides of the pit to prevent the pit from collapsing due to the removal of the cross brace. The removed cross brace is lifted at one end by the lifting mechanism, so that the cross brace stands upright on one side of the pit and does not interfere with pipe feeding. After the pipe is fed to the bottom of the pit, the positioning mechanism positions the pipe, assisting in pipe positioning and facilitating pipe alignment.

[0021] One side of the support rod 1 has guide sleeves 2 at both ends, and the other side of the support rod 1 has slide rods 3 at both ends that extend into the guide sleeves 2 and slide within the guide sleeves 2. The guide sleeves 2 are equipped with hydraulic cylinders that drive the slide rods 3 to slide within the guide sleeves 2. The hydraulic cylinders drive the support rods 1 on both sides to move outward synchronously, supporting the inner wall of the foundation pit and preventing the foundation pit from collapsing due to the removal of the cross bracing when the pipe is lowered, thus ensuring safety and reliability.

[0022] The lifting mechanism includes a winch 4 mounted on the corresponding support rod 1. The end of the wire rope on the winch 4 is equipped with a hook 5. When the cross brace is removed, the end of the cross brace is hooked by the hook and the cross brace is lifted without interfering with the feeding of materials into the pipeline.

[0023] The lower end of the support rod 1, corresponding to the lifting mechanism, is provided with a base plate 6 that can move left and right. After the cross brace is removed, one end of the cross brace is supported on the base plate 6, and the hook 5 hooks the other end of the cross brace to prevent the cross brace from swaying when it is erected, which is safe and reliable.

[0024] The support rod 1 is provided with a bracket 7, and the winch 4 is installed on the bracket 7.

[0025] The positioning mechanism includes a column 8 located at the lower end of the support rod 1. A baffle 9 is provided at the lower end of the column 8. After the pipe is placed, the baffle positions the pipe to prevent it from shifting or misaligning.

[0026] The support rod 1 is provided with four lifting rings 10 to prevent lifting.
