Description

Technical Field

[0001] The utility model belongs to the technical field of inspection well construction, and particularly relates to a device for controlling the distance between pipelines entering the inspection well at both sides. Background Art

[0002] When constructing a cast-in-place concrete inspection well or a brick concrete inspection well, it is necessary to first place the pipes on both sides, arrange the well spacing, and then cast the inspection well. If the pipe placement is not accurate, the well spacing will be wrong, which will make the later pipe installation time-consuming and laborious. Sometimes it is necessary to cut the pipe later to eliminate the well spacing error caused by the early pipe placement. The processing process is complicated, delays the construction period, and increases the project cost. Summary of the invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the background technology and provide a device for controlling the distance between pipelines entering the well on both sides of the inspection well.

[0004] The present invention is achieved through the following technical solutions:

[0005] A device for controlling the spacing between pipelines entering an inspection well on both sides of the inspection well comprises two symmetrical H-shaped vertical frames, two horizontal bars are symmetrically connected between the cross bars of the two H-shaped vertical frames, the horizontal bars are perpendicular to the cross bars, short sleeves are slidably sleeved on the two horizontal bars, the two short sleeves are fixedly connected by a connecting rod, and the connecting rod is parallel to the cross bars of the H-shaped vertical frames; the connecting rod symmetrically fixes two vertical bars downward, the bottom ends of the vertical bars are fixedly connected to a bottom support frame, and the bottom surface of the bottom support frame is flush with the bottom surface of the H-shaped vertical frames; a center rod is fixedly connected vertically downward at the middle position of the connecting rod, and the bottom end of the center rod is flush with the bottom surface of the bottom support frame.

[0006] Preferably, the horizontal rod comprises a rod A and a rod B which are slidably sleeved together, and corresponding adjustment holes are provided on the rod A and the rod B, and the rod A and the rod B are connected together by a T-pin passing through the adjustment hole.

[0008] Preferably, a threaded hole is provided on the outer side surface of the short sleeve, and the short sleeve is fixed to the horizontal rod by a bolt passing through the threaded hole.

[0009] The device of the present invention can accurately control the distance between the pipes on both sides of the inspection well before the inspection well is constructed, avoiding the problem of pipe cutting or pipeline installation difficulties at a later stage. The device of the present invention has a telescopic structure that can realize the control of the distance between the pipes in the inspection wells with different diameters.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0015] This embodiment includes two symmetrical H-shaped vertical frames 1, which are composed of two vertical bars and a cross bar. Two horizontal bars are symmetrically connected between the cross bars of the two H-shaped vertical frames 1. The horizontal bars are perpendicular to the cross bars. Short sleeves 2 are slidably connected on the two horizontal bars. The short sleeves 2 can slide left and right along the horizontal bars. A connecting rod 3 is fixed between the two short sleeves 2. The connecting rod 3 is parallel to the cross bars of the H-shaped vertical frame 1. Two vertical bars 4 are symmetrically fixed vertically downward on the connecting rod 3. The bottom ends of the vertical bars 4 are fixedly connected to the bottom support frame 5. The bottom surface of the bottom support frame 5 is flush with the bottom surface of the H-shaped vertical frame 1. The bottom support frame 5 is used to support the structure connected to the short sleeve 2. The structure of the bottom support frame 5 is not limited. In this embodiment, the bottom support frame 5 is composed of four horizontal bars staggered. A center rod 6 is fixedly connected vertically downward in the middle position of the connecting rod 3. The bottom end of the center rod 6, the bottom surface of the bottom support frame 5 and the bottom surface of the H-shaped vertical frame 1 are all flush. The center rod 6 is used to locate the center position of the inspection well. In order to make the structure connected by the short sleeve 2 more solid, it is preferably connected between the two vertical rods 4 with a support rod 11, the support rod 11 is parallel to the connecting rod 3, and the center rod 6 passes vertically downward through the support rod 11.

[0016] In order to make the device of the present invention suitable for controlling the distance between inspection wells of different diameters, the horizontal rod is preferably a telescopic rod. Specifically, the horizontal rod includes a rod A7 and a rod B8 that are slidably sleeved together. One end of the rod A7 and the rod B8 close to the H-shaped vertical frame 1 is fixed together with the cross bar of the H-shaped vertical frame 1, and the other end is a sleeve end. The rod B8 can slide left and right in the rod A7. Corresponding adjustment holes 9 are provided on the rod A7 and the rod B8. The total length of the horizontal rod is adjusted through the adjustment hole 9, and the rod A7 and the rod B8 are fixedly connected together by a T-pin 10 passing through the adjustment hole 9.

[0017] In order to ensure that the short sleeve 2 is not accidentally touched and displaced during construction, preferably, a threaded hole 12 is provided on the outer surface of the short sleeve 2, and the short sleeve 2 is fixed to the horizontal rod by a bolt 13 passing through the threaded hole 12 to prevent displacement.

[0018] Usage process: first adjust the total length of the horizontal rod according to the diameter of the inspection well to be constructed, then measure the center position of the horizontal rod, slide the short sleeve 2 to the center position of the horizontal rod, and then use the bolt 13 to fix the short sleeve 2. According to the construction design, find the center point of the inspection well and mark it. Place the entire device at the pre-constructed inspection well position, so that the bottom end of the center rod 6 is located at the center point of the inspection well, and then place the pipes on both sides directly against the outside of the H-shaped vertical frame 1 on both sides, as shown in the attached figure. Figure 1 As shown, the pipeline placement position at this time is the correct pipeline entry spacing during subsequent inspection well construction.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
