Description

Technical Field

[0001] The invention relates to the field of civil engineering, and in particular to an assembled micro pile foundation for a power transmission line and a processing method thereof. Background Art

[0002] During the construction of power transmission lines, the safety of the foundation structure is of vital importance. It is a key factor in ensuring the stability and reliability of the entire power transmission line. At present, the traditional practice is to complete the construction of the foundation structure by pouring on site. This method requires pouring and curing concrete on site, and at the same time, it is necessary to build formwork and tie steel bars, which requires a lot of manpower. Since the foundation pit needs to be open for a long time, this will lead to unstable quality of the finished foundation poured on site and there is a large degree of discreteness. In addition, on-site construction is also accompanied by high safety risks and noise pollution, which has a great impact on the surrounding environment. At the same time, it is also affected by the climate, making the maintenance of concrete particularly difficult.

[0003] At present, in the research field of transmission line foundation construction, most of the methods of prefabricated foundation structure are adopted. However, in order to ensure the firmness and stability of the foundation structure, the prefabricated size is usually large and the concrete weight is heavy. Although this design enhances the overall strength of the structure, it also brings considerable challenges. Due to the large size and weight of the components, the requirements for mechanical equipment during the construction process are significantly increased, especially in the transportation and on-site installation links, which pose great safety risks. The transportation and operation of large machinery not only require specialized equipment, but also require the construction of temporary construction roads and complex site leveling. These preparations often take up a lot of time and resources. In addition, in areas with complex terrain, the entry and operation of large machinery are more difficult, and may even be unusable due to terrain restrictions. In order to complete the construction, additional machinery and equipment have to be rented. These additional steps and costs undoubtedly further extend the construction period and increase the overall cost of the project. Therefore, in the current construction environment, how to reduce dependence on large machinery and improve the flexibility and economy of construction has become an urgent problem to be solved. Summary of the invention

[0004] The purpose of the present invention is to provide a transmission line assembled micro pile foundation to solve the technical problems of inconvenience in transportation and installation in the prior art when the overall prefabricated foundation structure is used.

[0041] The present invention will be further described below in conjunction with the embodiments of the present invention and the accompanying drawings.

[0042] Embodiment 1 of a transmission line assembled micro pile foundation of the present invention:

[0043] The specific structure of the assembled micropile foundation of the transmission line is as follows: Figures 1 to 15 As shown, it includes four foundation blocks 100, columns 200, piles 300 and connecting parts 400.

[0044] The four platform blocks 100 are assembled to form a complete square platform. Each platform block 100 includes a platform body 11. The center portion of the platform body 11 is provided with a first arc-shaped groove 12. The platform body 11 includes an inner side 13 for connecting with other blocks and an outer side 14 located around the platform after being connected to form a complete platform. The angle of the first arc-shaped groove 12 is 90 degrees. The first arc-shaped grooves 12 of the four platform blocks 100 can be assembled into a complete cylindrical hole, and the complete cylindrical hole is used for installing the column 200. A bolt hole 16 is arranged on one side of the first arc-shaped groove 12 on the platform body 11, and the bolt hole 16 is used to connect with the column 200.

[0045] In this embodiment, along the up and down direction, the first arc groove 12 includes a large diameter section 121 at the bottom and a small diameter section 122 at the top, and the column 200 correspondingly includes a large diameter column section 21 at the bottom and a small diameter column section 22 at the top. An embedded bolt 23 is protrudingly provided on the upper end surface of the large diameter column section 21. The embedded bolt 23 is used to be inserted into the bolt hole 16 to achieve a stable connection between the column 200 and the base block 100.

[0046] The inner side 13 of the cap body 11 is provided with a second arc groove 15. A sleeve 17 is provided on the inner wall surface of the second arc groove 15. The sleeve 17 includes an arc body 171 with an angle of 180 degrees, straight connecting ear plates 172 located on both sides of the arc body 171, anchoring ribs 173 fixed on the outside of the sleeve 17, and vertical bolts 174 fixed on the sleeve 17. The anchoring ribs 173 are used to achieve mechanical connection with the cap body 11, and the vertical bolts 174 are used to provide an anchor point for connection. The angle of the arc body 171 is also 180 degrees, and it can be assembled with the corresponding arc body on another cap block 100 to form a complete cylindrical hole, and the complete cylindrical hole is used for the installation of the pile 300.

[0047] Three of the cap blocks 100 are assembled together in the horizontal direction, and the fourth cap block 100 is vertically mounted on the three assembled cap blocks. The corresponding two cap blocks 100 assembled in the horizontal direction are connected by a horizontal connection structure. Specifically, the corresponding connection ear plates 172 of the two cap blocks 100 are respectively provided with bolts 175 and bolt through holes 176. When the two cap blocks 100 are connected, the bolts 175 on one cap block 100 are inserted into the bolt through holes 176 on the other cap block 100, and then nuts are used for auxiliary fixation. Among them, a post-casting strip 18 is left on the cap body 11 behind one side of the connection ear plate 172 provided with the bolt through holes 176. The purpose of the post-casting strip 18 is to cast concrete in the post-casting strip after the cap blocks 100 are connected, so as to connect the sleeves 17 on the two cap blocks into one by the bond strength of the concrete.

[0048] The corresponding two pedestal blocks 100 assembled in the vertical direction are connected through a vertical connection structure, specifically as follows: an upper sleeve 177 and a lower sleeve 178 are respectively provided on the two connecting ear plates 172 to be connected, the inner diameters of the upper sleeve 177 and the lower sleeve 178 are the same and both are provided with matching bolt holes, after the fourth pedestal block 100 is placed in place, the upper sleeve 176 and the lower sleeve 177 correspond to each other up and down, and a long screw (not shown in the figure) is inserted through the two, and the two can be connected as a whole with the aid of a nut for limiting. It should be emphasized that the corresponding sleeves on the two connecting ear plates 172 to be connected need to be marked in advance to ensure that the threads on the upper sleeve 172 and the lower sleeve 177 that have been processed can be properly engaged. At the same time, in a set of vertical connection structures used in combination, the sum of the heights of the upper sleeve 177 and the lower sleeve 178 is equal to the height of the arc-shaped body 171, and the height of the connecting ear plate 172 is consistent with the height of the upper sleeve 177 or the lower sleeve 178 fixed thereon. In a set of vertical connection structures used in combination, the upper sleeve 177 is arranged at the end of the connecting ear plate 172 away from the pedestal body 11, the lower sleeve 178 is arranged at the end of the connecting ear plate 172 close to the corresponding pedestal body 11, and a gap is left between the lower sleeve 178 and the pedestal body 11, and the gap forms a post-casting strip 18 for pouring the vertical connection structure therein.

[0049] In other embodiments, only a vertical connection structure may be provided on the sleeve 17. In this case, all the support blocks 100 are connected and fixed via the vertical connection structure.

[0050] The pouring of the foundation body 11 is carried out after the sleeve 17 is mechanically connected to the foundation body 11, so that the sleeve 17 and the foundation body 11 can have a certain strength through mechanical connection, and the bonding strength of the concrete can be further improved.

[0051] The pile 300 includes a prefabricated pile body 31 and a pre-embedded bolt 32 protruding from the center portion of the upper end surface of the pile body 31 .

[0052] The connector 400 includes a plate connector 41, an angle connector 42 and a straight connector 43. The plate connector 41 is provided with three bolt holes for inserting the embedded bolts 232 and the vertical bolts 174 on the corresponding two cap blocks 100. The plate connector 41 is used to connect the pile 300 to the cap block 100 and fix the upper end faces of the two adjacent cap blocks 100 as a whole. The two arms of the angle connector 42 are each provided with a bolt hole, and the outer side 14 of the cap body 11 is pre-set with bolt holes. The angle connector 42 is used to fix the outer side edges of the two adjacent cap blocks 100 as a whole. The straight connector 43 is used to connect the two adjacent cap blocks 100 again through two embedded bolts 123.

[0053] The processing method of the assembled micro pile foundation of the power transmission line of the present invention is as follows:

[0054] The first step is to prefabricate or process the foundation blocks 100, columns 200, piles 300, and connectors 400;

[0055] The second step is to connect the four caps into a complete square cap at the construction site in blocks of 100;

[0056] In this step, when connecting four cap blocks 100, first hoist the four cap blocks 100 into place. When the first three cap blocks 100 are connected, the bolts 174 and bolt holes 175 on the two adjacent cap blocks 100 are inserted together and fixed with nuts. After the last cap block 100 is vertically inserted into place, it is fixed with the help of long screws and nuts. After that, the outer sides of the four cap blocks 100 are fixed together by the angle connector 42; then, concrete is poured in the post-casting strip 18, and the connection of the cap is completed after the concrete curing is completed.

[0057] The third step is to complete the connection between the column 200 and the base, and between the pile 300 and the base.

[0058] After the column 200 is connected to the cap, a straight-line connector 43 is provided at the joint of the two cap blocks 100, and nuts are screwed on the portion of the embedded bolt 1 23 protruding from the straight-line connector 43. After the pile 300 is connected to the cap, a plate-shaped connector 41 is also provided at the joint of the two cap blocks 100, and nuts are screwed on the portion of the embedded bolt 2 32 and the vertical bolt 174 protruding from the plate-shaped connector 41. All nuts protruding from the cap are installed from above, which is convenient for on-site construction operations.

[0059] It should be emphasized that in order to ensure the connection strength, the cement mortar used is high-strength concrete. Before the components are spliced, sulfur cement needs to be applied to the connection surface. When pouring the post-casting strip, the gap between the connection structure and the concrete is filled by pressure grouting technology. The grouting material is C60 high-strength grouting material with micro-expansion characteristics. The bolts used must be of high-strength grade and must meet the requirements of the JGJ82-2011 specification on the hole distance and edge distance of high-strength bolts.
