Description

Technical Field

[0001] The utility model relates to the technical field of municipal water supply pipelines, in particular to a municipal water supply pipeline repair and reconstruction construction structure based on a rapid positioning structure. Background Art

[0002] As the service life of municipal water supply pipelines increases, it is imperative to repair and renovate them accordingly. Sometimes new pipelines are arranged in parallel with old pipelines. At this time, a three-way joint is installed on the old pipeline to take out the water. In field construction, large-diameter (large-diameter pipelines usually have specifications of DN1400, DN1600, DN1800, DN2000, DN2200, DN2400, DN2600, DN2800, DN3000, etc.) water supply pipelines often need to be hoisted with 90-degree elbows to complete the docking of pipelines. 90-degree elbows are usually hoisted by excavators due to their large size to complete the docking operation. However, the docking efficiency of large-diameter municipal pipelines with 90-degree elbows is usually low, which affects the progress and efficiency of construction, and there are also serious problems with on-site safety. Utility Model Content

[0005] The original municipal water supply pipeline is led out through the half joint and has an external interface with a flange;

[0006] A post-installed 90-degree post-installed adapter is arranged between the external interface and the butt-jointed pipe section. The first butt-jointed end of the 90-degree post-installed adapter is positioned and installed at the butt-jointed interface of the butt-jointed pipe section through an extended positioning block, and the first butt-jointed end is connected to the butt-jointed pipe section by welding. The second butt-jointed end of the 90-degree post-installed adapter is provided with a post-installed flange, which is connected to the flange of the external interface.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0017] Figure 1 For the operators, the height of the pipe suspended in the foundation pit is controlled at 30-50cm while the construction cost will be increased easily if the suspension height is too high.

[0018] The embodiment of the utility model provides a municipal water supply pipeline repair and reconstruction construction structure based on a rapid positioning structure, see Figure 1It includes a foundation pit 1 for installing an adapter. A square excavation groove is excavated by an excavator or manually. The edge of the foundation pit has an original municipal water supply pipe 2 suspended in the foundation pit. The foundation pit has a docking part of a newly installed municipal pipe. The newly installed municipal pipe is parallel to the original municipal water supply pipe. The newly installed municipal pipe requires water supply from the original municipal water supply pipe. The docking part of the newly installed municipal pipe has a docking pipe section 3 suspended in the foundation pit. The length of the docking pipe 3 can be 30-50cm. Two extension-type positioning blocks 4 are arranged on the upper half of the docking pipe section. The extension-type positioning block has an extension part extending from the front edge of the docking pipe section, so that it is convenient to use the extension part to contact the surface of the docking pipe 3 to complete relative positioning.

[0019] Continue to see Figure 1 The original municipal water supply pipeline is led out through the half joint 5 to an external interface 6 with a flange. The installation of the half joint in the original municipal water supply pipeline belongs to the prior art and will not be elaborated here. In the actual construction process, the external interface 6 has its own flange, and the adapter 7 connected to it is connected to the external interface 6 after the welding operation with the docking pipe 3 is completed, and then the matching flange is installed as needed.

[0020] See also Figure 1 A post-installed 90-degree post-installed adapter 7 is arranged between the external interface 6 and the butt pipe section. The adapter 7 can be lifted by an excavator. The first butt end 7a of the 90-degree post-installed adapter is positioned and installed at the butt interface of the butt pipe section through an extensional positioning block, and the first butt end 7a and the butt pipe section are connected by welding. The appearance of the two extensional positioning blocks can prevent the adapter from undergoing large displacement and deflection during the butt joint process, and the positioning requirement can also be met by utilizing the abutment effect of the lower surface of the extensional positioning block. The second butt end of the 90-degree post-installed adapter is provided with a post-installed flange 7b (subsequently welded to the adapter and welded and installed according to the on-site dimensions), and the post-installed flange 7b is connected to the flange of the external interface 6.

[0021] It should be pointed out that the extension type positioning block is welded and fixed on the surface of the butt pipe section. It can be cut after the pipe butt work is completed, or it can be kept at the construction site. The angle between adjacent extension type positioning blocks is 15-30°. This structural design matches the curved surface of the pipe, and the narrow curved space is more conducive to the needs of pipe butt work.

[0022] As another embodiment, the portion of the extended positioning block 4 that is located at the butt joint pipe section (defined as the base 4a of the extended positioning block is made of metal, and the extended portion 4b of the extended positioning block is made of plastic material. The extended portion of the plastic material is connected to the base of the butt joint pipe section by a detachable structure. For example, two stabilizing rods 4b-1 that penetrate the base are arranged in the extended portion, and the base is matched with the stabilizing rod mounting holes that are horizontally distributed therewith. The stabilizing rod has an exposed head that extends out of the base, and the exposed head is provided with a locking hole. Here, the locking holes of the two stabilizing rods are coaxially distributed in the vertical direction, and a magnet ring can be provided inside the locking hole. A metal rod 4b-2 can be installed in the locking hole of the exposed head to fix the base and the extended portion. The advantage of using this detachable structure is that the plastic material can be used to protect the adapter, and the characteristics of the plastic material can be used to give the adapter a certain buffering effect during the installation process.

[0023] As another example, see Figure 3-4 The upper part of the extended positioning block 4 is provided with a U-shaped groove 4c, and two adjacent extended positioning blocks are provided with a handle 8 located in the U-shaped groove, and the handle 8 has two handle ears with a width greater than the U-shaped groove. Since the extended positioning block is a structure with a height greater than the thickness, the handle can be used to improve the stability of the extended positioning block. If the extended positioning block is made of metal, considering the environment of the construction site, the handle ears can be embedded in the magnet block, which can make the installation stability of the handle more friendly and avoid the loss of items and the risk of falling due to overturning during the pipe hoisting process.

[0024] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
