Detailed Description
The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In this application, where the contrary is not stated, the use of directional words such as "upper, lower, left and right" generally means upper, lower, left and right as illustrated with reference to the accompanying drawings; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
According to one aspect of the present application, there is provided a line protection assembly, wherein the line protection assembly comprises at least two protection members 10 which are spliced to each other to form a closed inner cavity S, each protection member comprising an outer wall portion 11 and an inner cavity portion 12 fixed inside the outer wall portion 11 to form an inner surface of the inner cavity S, the inner cavity portion 12 having a smooth surface forming the inner cavity S.
When an existing pipeline is suddenly encountered, the protective member 10 may be assembled on site so that a portion of the existing pipeline (e.g., the pipeline 20) passing through the construction site is accommodated in the cavity S, thereby providing a protection function to the existing pipeline through the outer wall portion 11, and the cavity portion 12 has a smooth surface capable of facilitating a drag movement of the existing pipeline. Therefore, when the construction, can provide the protection to existing pipeline through the pipeline protection subassembly of this application fast, need not to move and change existing pipeline, improve the efficiency of construction.
Wherein the protection function for the pipeline 20 is mainly provided by the outer wall 11, and the inner cavity 12 mainly functions to isolate the outer wall 11 from the pipeline 20, so as to prevent the uneven part of the outer wall 11 from damaging the pipeline 20. Therefore, the inner cavity portion 12 can be made of various materials capable of forming a smooth surface. For example, as shown in FIG. 1, the inner chamber portion 12 may be a piece of PVC. Alternatively, as shown in FIG. 2, the inner cavity portion 12 may be a wire bridge. In addition, the appropriate interior chamber portion 12 may be selected depending on the type of line 20 being used. For example, when the diameter of the pipeline 20 is large and the pipeline 20 is a non-electric pipeline such as a water pipe or a gas pipe, the inner cavity 12 of the PVC member may be used; when the line 20 is a weak current line such as a cable or a communication line, a wire bridge may be used for the inner cavity 12.
In addition, a plurality of pipelines 20 arranged in parallel may be encountered suddenly at the time of construction. In this case, the outer surface of the outer wall 11 may include a flat portion so that a plurality of lines 20 can be protected by combining a plurality of line protection modules, as shown in fig. 7 and 8, and the outer wall 11 forms a rectangular cross section after being combined so that a plurality of line protection modules can be stacked side by side to reinforce stability with each other.
Alternatively, as shown in fig. 9, the wire bridge may be configured to divide the internal cavity into at least two line receiving portions 13 to receive different lines 20 through different receiving portions 13. The form of the wire bridge can be designed according to the desired partitioned accommodation 13.
Further, the line protection assembly is provided with an inner cavity S extending along a predetermined route. Thus, the desired line protection component can be selected according to the layout of the line 20. For example, in the embodiment shown in fig. 3, the lumen S of the line protection assembly has a curved course with a bend angle of about 135 °; in the embodiment shown in fig. 4, the lumen S of the line protection module has a curved course with a bending angle of about 90 °; in the embodiment shown in fig. 5, the lumen S of the line protection assembly forms a three-way structure; in the embodiment shown in fig. 6, the lumen S of the line protection assembly forms a four-way structure.
It will be appreciated that during construction, various designs of pipeline protection assemblies (e.g., having different numbers of receptacles 13, different internal cavity sizes, different lengths) may be selected to meet the needs of a particular pipeline 20 type encountered during construction.
In this application, the number of protective members 10 can be set as desired to form a complete lumen S in a pieced-together manner. For cost and efficiency, as shown in fig. 1 and 2, the pipeline protecting assembly may include two protecting members 10 spliced to each other to form the inner cavity, the two protecting members are a first protecting member 10a and a second protecting member 10b, respectively, and the first protecting member 10a and the second protecting member 10b are spliced by an inclined plane. By splicing the first protection member 10a and the second protection member 10b through the inclined plane L, the inclined plane can be inclined downwards along the direction outward from the inner cavity S when in use, so that the inner cavity S is favorably sealed, and surrounding sand, water and soil are prevented from entering the inner cavity S from the spliced position of the first protection member 10a and the second protection member 10b during construction. Wherein, in order to take sealing performance and splicing convenience into consideration, the angle of the inclined plane L can be 40-50 degrees, and is 45 degrees in figure 1.
In addition, the outer wall 11 is mainly used for protection and may be made of a material having appropriate strength. Preferably, the outer wall 11 is a concrete element to provide protection against the surrounding environment in which it is buried. In this case, the protective member 10 may be a concrete preform, that is, formed by pouring concrete with the inner cavity portion 12 as an inner surface.
According to another aspect of the present application, there is provided a line protection device, wherein the line protection device comprises at least two line protection modules of the present application to accommodate different lines 20 through the lumen S of each of the line protection modules. Thus, protection may be provided for multiple lines 20 by a line protection device, as shown in fig. 7 and 8.
The use of the line protection assembly of the present application is described below in conjunction with the drawings.
When an existing pipeline 20 is encountered during construction, the pipe diameter, number, length (suitably longer than the length of the portion overlapping the construction range), and pipeline property (whether or not the pipeline is weak) of the pipeline 20 to be protected are first determined, and an appropriate pipeline protecting component is selected based on the above information.
Then, a mounting groove is excavated below the pipeline 20, and the pipeline 20 can be positioned and protected by temporary measures such as brackets, suspension members, and the like. Then, a protective cushion 30 is laid at the bottom of the installation groove (the material of the protective cushion 30 can be selected according to the specific construction environment, for example, in a geological region, a 30cm gravel cushion or a 10cm C20 plain mixed concrete cushion is used). After the cushion flatness inspection is passed, the protection members 10 are sequentially placed to accommodate the pipeline 20 in the inner cavity S. For example, in the embodiment shown in fig. 1, the second protective member 10b is placed first, then the line 20 is placed in the lumen portion 12 of the second protective member 10b, followed by placement of the first protective member 10a to complete the splice with the second protective member 10 b.
Subsequently, the joint of the first protective member 10a and the second protective member 10b is sealed, for example, with a cement sand grade seal of M15. It will be appreciated that a plurality of pipeline protection modules may be used arranged in series along the length of the pipeline 20 to meet the length requirements of the desired protection. Adjacent pipeline protection components may also be sealed by M15 cement sand stage sealing.
Finally, the installation channel can be backfilled, for example by means of crushed stone, sand or plain concrete, the degree of compaction being adjustable according to the construction needs, but generally not less than 95%.
After completion of the protection of the pipeline 20, construction may begin, for example, to form the pavement structure 40.
The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present application within the technical idea of the present application, and these simple modifications all belong to the protection scope of the present application.
It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described in the present application.
In addition, any combination of the various embodiments of the present application can be made, and the same should be considered as the disclosure of the present invention as long as the combination does not depart from the spirit of the present application.
