Detailed Description

As shown in fig. 1 to 9, an existing pipeline protection device for foundation pit engineering mainly comprises a protection frame 1, a protection frame supporting tube 3 and an existing pipeline fixing bracket 2. The embodiment is a modularized device, and each protection frame 1, each protection frame supporting tube 3 and each existing pipeline fixing support 2 in the device are assembled in a lifting type protection mode, so that risks of deformation, sagging and cracking, mechanical bruising and the like of a pipe body are avoided. Meanwhile, the method can be arranged rapidly on site, the materials can be guaranteed to be reused, and labor cost is effectively reduced.

For example, because the angle steel has lighter weight and less consumed materials under the same supporting strength, the cost can be effectively saved, the construction is convenient, and the occupied space is small, so in the embodiment, the protection frame 1 comprises the angle steel, the protection frame top plate 12, the protection frame bottom plate 14, the connecting piece 11 and the connecting rod 15, the connection between the protection frame top plate 12 and the protection frame bottom plate 14 is realized through the connecting piece 11, and the connecting piece 11 is at least two. Because the triangle structure is most stable, the oblique connecting rod 15 is additionally arranged between the two adjacent connecting pieces 11, the two connecting pieces 11 are fixedly connected by adopting the connecting bolts 13, and the protection frame top plate 12 and the protection frame bottom plate are connected to form the triangle structure, so that the structure of the protection frame 1 is more stable.

As shown in fig. 3, the protective frame support tube 3 is fixedly connected with the protective frame bottom plate 14 through the mutual matching of the flange nuts 32 and the flange bolts 33. The protective frame bottom plate 14 is fixedly connected with the existing pipeline fixing support 2 through a flange nut 32 and a flange bolt 33. In the use, the protection frame stay tube 3 lays in foundation ditch bottom 4, because the depth of each foundation ditch is different, so protection frame stay tube 3 is a plurality of support columns 31 equipment and forms, can assemble according to the altitude of job site to guarantee the requirement that protection frame 1 and pipeline are in same horizon.

As shown in fig. 5 and 6, the existing pipeline fixing bracket 2 in the present embodiment specifically includes an existing pipeline 21, an aperture adjusting spacer 22, a fixing 0-type pipe clamp 23, a carbon steel nut 24, a carbon steel screw 25, a support plate 26, and a rib plate 27. Two bracing pieces 261 are located the connecting plate 262 both sides, adopt welding, fastener connection or integrated into one piece, the backup pad of whole constitution U type structure, connecting plate 262 and protection frame bottom plate 14 fixed connection are equipped with the opening on the bracing piece 261, consequently bracing piece 261 constitutes an inverted L style of calligraphy structure, the opening is outwards equipped with the tie point that is used for wearing to establish bolt or screw rod on the opening, locking fixed connection is fixed 0 type pipe strap 23 at the both ends of carbon steel screw rod 25 through carbon steel nut 24, can carry out the high fine setting to existing pipeline fixed bolster 2 through the quantity of placing the nut like this, carry out nimble regulation according to the size of existing pipeline.

Meanwhile, in order to ensure stable strength, in this embodiment, the rib plates 27 are provided on the rim of the support rod 261, and the longitudinal sections of the rib plates 27 are triangular structures, so that the support strength of the support plate 26 can be effectively enhanced.

Because the condition that the existing pipeline exists underground is frequently met in foundation pit engineering, the pipeline is mostly a gas pipeline, a heating power pipeline, a drainage pipeline, a water supply pipeline, an electric power protection pipe and the like, and the pipe diameters of the pipelines need to be protected are different. Therefore, the aperture adjusting pad 22 contacted with the pipeline in this embodiment can adjust the pipe diameter in a combined and stacked manner, so that the existing pipeline protection device for foundation pit engineering has a wider pipe diameter range.

As shown in fig. 7 and 8, considering that the connection between the aperture adjusting pad 22 and the fixed 0-type pipe clamp 23 has no limit structure when the locking is not performed, the aperture adjusting pad 22 slides off from the fixed 0-type pipe clamp 23, and the installation efficiency is reduced. Therefore, in this embodiment, the limiting block is disposed on the aperture adjusting cushion block 22, and the limiting groove 53 embedded by the limiting block 52 is disposed on the fixing 0-type pipe clamp 23, and the groove 51 is disposed on the inner circumferential surface of the aperture adjusting cushion block 22, so that the overlapping assembly of a plurality of aperture adjusting cushion blocks 22 can be realized. During superposition assembly, limiting blocks 52 on the adjacent aperture adjusting cushion blocks 22 can be embedded into grooves 51 on the adjacent aperture adjusting cushion blocks 22 for positioning, so that the stability of the structure of each layer of aperture adjusting cushion block 22 is improved. The projection surfaces of the limiting block 52, the groove 51 and the limiting groove 53 are rectangular structures, perfect matching can be achieved, because the limiting groove is uniformly distributed along the circumference of the fixed 0-shaped pipe clamp, and the limiting block 52 is uniformly distributed along the circumference with the limiting groove 53 and the groove 51, the limiting block 52 and the groove 51 are uniformly distributed along the circumference, the number of the limiting block 52 and the groove 51 is at least three, and the stability of the position is further improved.

According to the utility model, the operation safety of the existing pipeline in the foundation pit can be effectively protected in the use process. And the device can be increased along with the depth of the foundation pit, and the height of the whole protection device can be adjusted by additionally installing the supporting columns 31. In the whole foundation pit construction process, if the safety inspection personnel find that the pipeline is slightly deformed, the safety inspection personnel can also adjust the safety inspection personnel through the existing pipeline fixing support 2 so as to ensure that the existing pipeline continuously operates under the best working condition, eliminate potential safety hazards caused by foundation pit construction and ensure the normal operation of the existing pipeline.

Meanwhile, the bolt connection adopted in the embodiment is simple in construction process, convenient to install and convenient to detach, so that the abnormal condition of the embodiment can be quickly adjusted, and unnecessary loss is reduced.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
