Description

Technical Field

[0001] This utility model belongs to the field of concrete pole technology, and specifically relates to a plug-in pole cup-mouth foundation. Background Technology

[0002] As the name suggests, a utility pole is a pole used to carry power lines. Found throughout rural areas, fields, roads, and streets, it was one of the important infrastructure projects in early China. Early utility poles, including even those for low-voltage lines, were all made of wood. Later, due to the development of steel and reinforced concrete, and technological advancements, these two materials replaced most wooden poles. Concrete utility poles are divided into prestressed and non-prestressed types.

[0003] The existing concrete pole installation requires pre-drilling installation pits in the ground before driving the bottom of the concrete pole directly into the foundation. However, environmental factors such as farmland and paddy fields make it inconvenient for cranes and transport vehicles to enter, further affecting the installation of concrete poles. In addition, concrete poles are relatively long and heavy, making construction and installation difficult. It is hard to install the concrete poles in a vertical position, and tilting the concrete poles can easily cause instability and lead to tipping over during use, affecting their usability. Utility Model Content

[0004] The purpose of this utility model is to provide a plug-in type socket foundation for utility poles, thereby overcoming the problems of inconvenient installation and difficult construction of traditional concrete utility poles. The specific technical solution is as follows:

[0006] The cup-shaped base assembly is pre-fixed at the location of the concrete pole to be installed, and the cup-shaped base assembly has an upward-facing insertion port.

[0007] A concrete pole is erected onto the cup-shaped foundation assembly through the insertion port.

[0008] Preferably, the cup-shaped foundation assembly includes a base and a sleeve. The base is installed in the foundation pit at the location where the concrete pole is to be installed and is buried with soil. The sleeve is inserted into the base.

[0009] Preferably, the burial soil does not cover the upper end face of the sleeve so that the insertion port located on the sleeve is exposed above the soil surface.

[0010] Preferably, the joint between the base and the sleeve is sealed by grouting material.

[0011] Preferably, the base includes a base plate and a conical insert cylinder. The conical insert cylinder is installed at the middle position of the base plate. The insertion diameter of the conical insert cylinder is larger than the diameter of the sleeve. When the sleeve is inserted into the conical insert cylinder, the outer wall of the sleeve and the inner wall of the conical insert cylinder are sealed with grout.

[0012] Preferably, the mass of the base and the sleeve does not exceed 3t.

[0013] Preferably, both the base and the sleeve are made of cast concrete.

[0014] Preferably, when the concrete pole is not installed, a protective cover can be added to the insertion port.

[0015] Compared with existing technologies, this utility model has the following beneficial effects:

[0016] This utility model provides a plug-in type cup-shaped foundation for utility poles. By pre-setting the cup-shaped foundation assembly, the concrete poles can be installed quickly, which greatly improves work efficiency and quality.

[0026] Example

[0027] like Figures 1 to 2 As shown, a plug-in type pole socket foundation specifically includes a socket foundation assembly 100 that is pre-fixed to the location where a concrete pole is to be installed. The plug-in port 110 of the socket foundation assembly 100 faces upward and exposes the upper surface of the location where the concrete pole is to be installed, so that the concrete pole 200 can be vertically installed onto the socket foundation assembly 100 through the plug-in port 110.

[0028] In some preferred embodiments, the cup-shaped foundation assembly 100 includes a base 120 and a sleeve 130. A foundation pit is excavated at the location where the concrete pole to be installed is to be dug. In order to avoid collapse and water accumulation in the excavated foundation pit, the excavated foundation pit needs to be constructed quickly. That is, after the foundation pit is excavated, the base 120 is quickly installed into the foundation pit. After the sleeve 130 is inserted into the base 120, the soil is backfilled to bury the cup-shaped foundation assembly 100 into the foundation pit. It is worth mentioning that the burying soil does not cover the upper end face of the sleeve 130 so that the insertion port 110 located on the sleeve 130 is exposed above the soil surface.

[0029] In some preferred embodiments, the base 120 includes a base plate 121 and a conical insert cylinder 122. The conical insert cylinder 122 is installed at the middle position of the base plate 121. The insertion diameter of the conical insert cylinder 122 is larger than the diameter of the sleeve 130. When the sleeve 130 is inserted into the conical insert cylinder 122, high-strength grout is injected between the outer wall of the sleeve 130 and the inner wall of the conical insert cylinder 122 to seal the gap (i.e., to complete the fixed connection between the base 120 and the sleeve 130). Similarly, the sleeve 1... The diameter of the insertion port 110 of sleeve 30 is larger than the diameter of the concrete pole 200 to be installed, so that the concrete pole 200 can be smoothly inserted into the cup-mouth foundation assembly 100. Similarly, high-strength grout is injected to fix the connection between sleeve 130 and concrete pole 200 (after the grout sets, the concrete pole 200 is fixedly connected to the cup-mouth foundation assembly 100). In this way, the concrete pole 200 can be installed quickly, which greatly improves work efficiency and quality.

[0030] In some preferred embodiments, in order to reduce the weight of the construction, the mass of the base 120 and the sleeve 130 shall not exceed 3t (this mass depends on the construction requirements and may sometimes be 2t, 2.5t or 3t).

[0031] In some preferred embodiments, both the base 120 and the sleeve 130 are made of cast concrete. The base plate 121 and the conical insert cylinder 122 can be cast integrally, or they can be cast separately and then assembled together.

[0032] In some preferred embodiments, when the concrete pole 200 is not installed, a protective cover can be added to the insertion port 110 (the cup-shaped foundation assembly 100 is installed as an embedded part or a pre-installed part at the location where the concrete pole is to be installed). The purpose of the protective cover is to prevent anything from blocking the insertion port 110 before the concrete pole 200 is installed, or to prevent water from accumulating in the insertion port 110 during rain. The protective cover protects the cup-shaped foundation assembly 100.

[0033] Next, the construction method and steps in this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0034] S1: Excavate a foundation pit at the location where the concrete pole to be installed is to be dug. The size of the foundation pit is sufficient to accommodate the cup-shaped foundation assembly 100. After the foundation pit is dug, in order to avoid the collapse and water accumulation of the foundation pit, quickly install the base 120 into the foundation pit.

[0035] S2: Insert the sleeve 130 into the base 120, and inject high-strength grout into the joint between the sleeve 130 and the base 120 to seal the joint. After the grout solidifies, backfill with soil to bury the cup-mouth foundation assembly 100 in the foundation pit. When backfilling, the burying soil does not cover the upper end face of the sleeve 130 so that the insertion port 110 on the sleeve 130 is exposed on the upper surface of the soil layer, so as to facilitate the subsequent insertion of the concrete pole 200.

[0036] S3: Transport the concrete pole 200 to be installed to the installation point where the cup-shaped foundation assembly 100 is pre-set. Vertically insert the concrete pole 200 into the cup-shaped foundation assembly 100 by hoisting. Similarly to the grouting operation in the above steps, inject high-strength grout between the concrete pole 200 and the inner wall of the insertion port 110 to achieve caulking. After the grout solidifies, the installation of the concrete pole 200 is completed.

[0037] S4: In another scenario, if the pre-assembled cup-shaped foundation assembly 100 does not require immediate installation of the concrete pole 200, a protective cover is added to the insertion port 110. The protective cover prevents anything from blocking the insertion port 110 before the concrete pole 200 is installed, or prevents water from accumulating in the insertion port 110 during rain. The protective cover protects the cup-shaped foundation assembly 100.

[0038] In summary, this utility model provides a plug-in type cup-shaped foundation for utility poles. By pre-setting the cup-shaped foundation assembly, the concrete poles can be installed quickly, greatly improving work efficiency and quality. When installing concrete poles, it is only necessary to transport the concrete poles to be installed to the designated installation site and quickly insert them into the cup-shaped foundation assembly by hoisting.
