Description

Technical Field

[0001] The present application relates to the technical field of municipal engineering, and in particular to a comprehensive pipe trench reinforcement structure. Background Art

[0002] A comprehensive pipeline trench refers to a structure and its ancillary equipment installed underground to accommodate two or more public and municipal pipelines. It can bring together part or all of the various underground pipelines such as electricity, telecommunications, heat, water supply, recycled water, gas, etc. that are scattered and independently buried underground into a common underground pipeline trench for joint maintenance and centralized management.

[0003] The walls of the traditional integrated pipe trenches on both sides of the road are generally brick structures, which are not strong and easy to damage. With the development of urban construction, it is necessary to reinforce the walls of the existing integrated pipe trenches. Since a large number of cables in use are installed in the existing integrated pipe trenches and cannot be relocated, the space in the integrated pipe trench is limited and the construction is extremely difficult. At present, excavation is often used outside the reinforcement position of the integrated pipe trench to increase the construction space during reinforcement, but this method has a large excavation range and a long construction period. Utility Model Content

[0004] The purpose of the present application is to provide a comprehensive pipe trench reinforcement structure to solve the problem of a large excavation range during reinforcement of the comprehensive pipe trench.

[0005] The technical solution adopted by the present application to solve its technical problems is: a comprehensive pipe trench reinforcement structure, including a concrete reinforcement wall arranged on one side of the bottom of the comprehensive pipe trench and extending upward, a plurality of vertically arranged steel columns are arranged in the concrete reinforcement wall, and the plurality of steel columns are arranged at intervals along the direction of the comprehensive pipe trench, and the lower ends of the steel columns pass through the bottom of the concrete reinforcement wall and extend downward to the foundation below the bottom of the comprehensive pipe trench.

[0006] Furthermore, the concrete reinforced wall is a cast-in-place structure.

[0007] Furthermore, transverse steel sections extending along the direction of the integrated pipe trench are arranged in the concrete reinforcement wall, and the transverse steel sections are connected to the steel columns.

[0008] Furthermore, the transverse steel section is welded to the upper end of the steel section column.

[0009] Furthermore, the steel column and the transverse steel are both I-beams.

[0010] Furthermore, transverse steel bars extending along the direction of the integrated pipe trench are arranged in the concrete reinforcement wall, and the transverse steel bars are connected to the steel columns.

[0011] Furthermore, the transverse reinforcement is connected to the steel column by welding.

[0012] Furthermore, the transverse reinforcement includes at least two layers spaced apart from top to bottom.

[0013] Furthermore, the spacing between two adjacent layers of the transverse steel bars is 20 to 30 cm.

[0014] Furthermore, the distance between two adjacent steel columns is 60 to 80 cm.

[0015] Beneficial effects of this application:

[0016] 1. An embodiment of the present application provides a comprehensive pipe trench reinforcement structure, which is used to reinforce the comprehensive pipe trench by setting a concrete reinforcement wall. By setting a steel column whose upper section is connected to the concrete reinforcement wall and whose lower section is inserted into the foundation below the bottom of the comprehensive pipe trench, the ability of the concrete reinforcement wall to resist lateral pressure and overturning is improved, thereby improving the firmness of the reinforcement structure.

[0017] 2. An integrated pipe trench reinforcement structure provided in an embodiment of the present application can first insert the lower section of the steel column downward into the foundation below the bottom of the integrated pipe trench, and then pour concrete on one side of the bottom of the integrated pipe trench and embed the upper section of the steel column in the concrete to form a concrete reinforced wall. Compared with the prior art, there is no need to excavate below the bottom of the integrated pipe trench, which greatly reduces the excavation amount and shortens the construction period. It is particularly suitable for situations where there are a large number of cables in use in the integrated pipe trench and the construction space is limited. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The integrated pipe trench 10 refers to a structure and its ancillary equipment set underground for accommodating more than two public and municipal pipelines, and is mainly composed of a trench bottom 101, trench sides 102 set on both sides of the trench bottom 101, and cover plates 103 set on the two trench sides 102. The traditional integrated pipe trench was built at an early time, and is generally a brick structure, which is not firm and easy to damage. With the development of urban construction, it is necessary to reinforce the trench sides of the existing integrated pipe trenches. However, since a large number of cables in use are installed in the existing integrated pipe trenches and cannot be relocated, the space in the integrated pipe trench is limited and the construction is difficult. At present, it is often used to excavate the outside of the reinforced position of the integrated pipe trench until it is excavated into the foundation below the trench bottom to increase the construction space, but this method results in a large excavation range and a long construction period.

[0031] In order to reduce the excavation scope of the integrated trench during reinforcement, see Figure 1 , Figure 2An embodiment of the present application provides an integrated pipe trench reinforcement structure, including a concrete reinforcement wall 11 arranged on one side of a trench bottom 101 of the integrated pipe trench 10 and extending upward, a plurality of vertically arranged steel columns 12 are arranged in the concrete reinforcement wall 11, and the plurality of steel columns 12 are arranged at intervals along the direction of the integrated pipe trench 10, and the lower ends of the steel columns 12 pass through the bottom of the concrete reinforcement wall 11 and extend downward to the foundation below the trench bottom 101 of the integrated pipe trench 10.

[0032] The comprehensive pipe trench reinforcement structure provided in the embodiment of the present application is used to reinforce the trench side 102 of the existing comprehensive pipe trench 10 by setting a concrete reinforcement wall 11, and by setting a steel column 12 whose upper section is connected to the concrete reinforcement wall 11 and whose lower section is inserted into the foundation below the trench bottom 101 of the comprehensive pipe trench 10, the lateral pressure resistance and overturning resistance of the concrete reinforcement wall 11 are improved, thereby improving the firmness and service life of the reinforcement structure. Among them, the length of the lower section of the steel column 12 inserted downward into the foundation should be set according to the strength calculation, and no specific limitation is made here.

[0033] When it is necessary to reinforce the trench side 102 of the integrated pipe trench 10, the trench side 102 to be reinforced can be removed first, and then the integrated pipe trench reinforcement structure provided in the embodiment of the present application can be constructed. Of course, if the trench side 102 to be reinforced is not convenient to remove, and there is enough space in the integrated pipe trench 10, the trench side 102 to be reinforced can be left unremoved, and the integrated pipe trench reinforcement structure provided in the embodiment of the present application can be directly constructed on the inner side of the trench side 102 to be reinforced.

[0034] In some embodiments, the concrete reinforcement wall 11 is a cast-in-place structure. Of course, the concrete reinforcement wall 11 can also be a prefabricated structure, wherein fixing holes for fixing the steel columns 12 need to be reserved on the prefabricated structure.

[0035] In some embodiments, see Figure 1 , Figure 2 , a transverse steel section 13 extending along the direction of the integrated pipe trench 10 is arranged in the concrete reinforcement wall 11, and the transverse steel section 13 is connected to the steel section column 12. By arranging the transverse steel section 13, it is used to connect all the steel section columns 12 together to form a whole, thereby further improving the firmness of the reinforcement structure. Exemplarily, the transverse steel section 13 is fixedly connected to the upper ends of all the steel section columns 12, and the upper surface of the transverse steel section 13 is flush with the upper end of the concrete reinforcement wall 11. The transverse steel section 13 and the upper end of the steel section column 12 can be welded; of course, the transverse steel section 13 and the steel section column 12 can also be connected by a bolt structure.

[0036] In some embodiments, the steel column 12 and the transverse steel 13 are both I-beams. For example, the steel column 12 and the transverse steel 13 are both made of 16# I-beams. Of course, in other embodiments, the steel column 12 and the transverse steel 13 can also be made of channel steel, angle steel, H-beam or other steel.

[0037] In order to further improve the firmness of the concrete reinforced wall 11, in some embodiments, see Figure 1 , Figure 2 , a transverse reinforcement 14 extending along the direction of the integrated pipe trench 10 is arranged in the concrete reinforcement wall 11, and the transverse reinforcement 14 is connected to the steel column 12. Exemplarily, the transverse reinforcement 14 is welded to the steel column 12. Further, the transverse reinforcement 14 includes at least two layers spaced from top to bottom. The transverse reinforcement 14 is HPB300φ8mm steel bar. The spacing between two adjacent layers of transverse reinforcement 14 is 20 to 30 cm. The spacing between two adjacent steel columns 12 is 60 to 80 cm.

[0038] See also Figure 1 The comprehensive pipe trench reinforcement structure provided in the embodiment of the present application is used to reinforce the ditch side 102 on the left side of the comprehensive pipe trench 10.

[0039] The construction process of the comprehensive trench reinforcement structure provided by the embodiment of the present application is as follows: clean the trench bottom 101, cut the steel columns 12, transverse steel sections 13 and transverse reinforcement bars 14 according to the required size; mark the insertion point of the steel column 12 at a spacing of 60 cm at the construction location, and manually cooperate with the excavator to insert the lower section of the steel column 12 downward into the foundation below the trench bottom 101 at the insertion point; when the construction of all steel columns 12 is completed, place the transverse steel sections 13 on the top of all steel columns 12 and weld them to all steel columns 12; then arrange several layers of transverse reinforcement bars 14 at a spacing of 20 cm on the upper section of the steel column 12 and weld them to the steel column 12; set the template according to the wall size and pour C20 concrete, and form the concrete reinforced wall 11 after the concrete solidifies; then remove the template, and cover the top of the trench with the cover plate 103 after the template is removed.

[0040] An integrated pipe trench reinforcement structure provided in an embodiment of the present application can first insert the lower section of the steel column 12 downward into the foundation below the trench bottom 101 of the integrated pipe trench 10, and then pour concrete on one side of the trench bottom 101 of the integrated pipe trench 10 and embed the upper section of the steel column 12 in the concrete to form a concrete reinforcement wall 11. Compared with the prior art, there is no need to excavate below the trench bottom 101 of the integrated pipe trench 10, which greatly reduces the excavation amount and shortens the construction period. It is particularly suitable for situations where there are a large number of cables in use in the integrated pipe trench and the construction space is limited.

[0041] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
