[0022] Hereinafter, in order to make the purpose, features and advantages of the present invention more clearly understood, only certain exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are considered to be exemplary and non-restrictive in nature.

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, the present invention provides a method for grouting mortar for embedded airport navigation lights, comprising:

[0025] S01: Pour the cushion mortar into the lamp pit where the core has been drilled, put the tamping tool into the lamp pit, and put the padding wood on it and hammer it to make it dense;

[0026] S02: After the bottom mortar is compacted, put the embedded lamp base in;

[0027] S03: Carry out tamping construction of the gaps on the side walls of the lamp pit;

[0028] S04: After the dry-mixed mortar on the side wall of the lamp pit is compacted, take out the tamping tool, remove the mud stains on the surface and let it dry naturally for future use;

[0029] S05: Cure the grouting mortar and apply the upper silicone sealant after the bottom mortar is completely dry.

[0030] In the prior art, workers' manual tamping has the following defects: ① If the method of hammering wood or bamboo pieces is adopted, the hammering force cannot be too large, and the grouting mortar is difficult to be dense, which may easily lead to cracking and damage of the upper potting glue in the later stage; if the method of hammering steel plates is adopted, due to the small gap between the side walls, the steel plates are easy to damage the corners of the lamp pit when hammered vigorously, and the later repair is time-consuming and labor-intensive, and it will affect the overall strength of the pavement. ② Due to the limited cross-sectional area of ​​the plate-like components, the position of the wood or steel plates needs to be constantly changed during the construction process, resulting in low work efficiency. In actual construction, workers often skip vibrations in order to save trouble and meet deadlines, resulting in uneven quality. ③ The force of each hammering cannot be consistent, resulting in uneven tamping. The square cross-section of the plate cannot be completely fitted with the annular side wall of the lamp pit, and vibration leakage in some areas cannot be avoided. Therefore, uniformity and density cannot be guaranteed, resulting in insufficient strength and uneven settlement and cracking in the later stage.

[0031] In this embodiment, a tamping tool is used to tamp and compact the grouting mortar in the lamp pit of the embedded navigation light. With the assistance of the tamping tool, a layered tamping construction method is adopted according to the depth of the lamp pit. One layer can be tamped at one time, and the tamping effect is more uniform, thereby effectively protecting the lamp pit opening and preventing corner damage. In addition, the tamping tool is adapted to the shape of the inner wall of the lamp pit, and full coverage can be achieved during tamping, thereby effectively avoiding vibration leakage and making the force more uniform, thereby improving construction efficiency. The tamping tool is assembled from metal parts and can be directly customized at a hardware store according to the size of the lamp pit. The production, assembly and disassembly processes are relatively convenient, and the tools require almost no maintenance. They can be reused for a long time, saving raw materials and thus reducing construction costs.

[0032] Furthermore, the pouring of cushion mortar for the lamp pit that has been drilled and cored specifically includes: leveling the bottom of the lamp pit after drilling and coring, supporting and fixing the lamp base, and making the lamp base meet the elevation requirements; when tamping the bottom mortar, sealing the pipe opening of the pre-buried cable protection pipe at the bottom of the lamp pit with geotextile.

[0033] In this embodiment, the functions of pouring the cushion mortar in the lamp pit are as follows: 1. leveling the bottom of the lamp pit after drilling and coring; 2. supporting and fixing the lamp base and making the lamp base meet the elevation requirements, so that the lamp installation elevation meets the design requirements;

[0034] Because a cable protection pipe is embedded in the bottom of the lamp pit, geotextile should be used to seal the pipe opening of the cable protection pipe when tamping the bottom mortar to prevent the mortar from entering the embedded pipe. After the bottom mortar is compacted and meets the elevation requirements, the embedded lamp base is placed in. The direction, centrality and other parameters of the base should meet the design requirements.

[0035] Furthermore, if Figure 2As shown, the tamping tool includes: an annular cast iron ring 1, a circular cast iron plate 2, and a plurality of stainless steel rods 3; one end of the stainless steel rod 3 is connected to the annular cast iron ring 1, and the other end of the stainless steel rod 3 is connected to the circular cast iron plate 2.

[0036] In this embodiment, three stainless steel rods 3 are provided, and the three stainless steel rods 3 are arranged in an equilateral triangle shape and are respectively connected to the annular cast iron ring 1 and the circular cast iron plate 2;

[0037] The thickness of the annular cast iron ring 1 is 8mm, the outer diameter is the diameter of the lamp pit minus 5mm, and the ring width is 25mm (the gap between the general lamp and the lamp pit is 30mm. If the gap is different due to different processes, the ring width should be adjusted appropriately. Otherwise, if the gap is too large, the vibration leakage area will be large, and if it is too small, it will be too tight and inconvenient to place. In principle, it is appropriate to have a 2.5mm gap with both sides for easy placement and tamping). Three screw holes are arranged in an equilateral triangle shape at a position 12.5mm away from the outer edge (in principle, half of the ring width), with a hole depth of 4mm and a hole diameter of 10mm;

[0038] The circular cast iron plate 2 has a thickness of 5 mm and a diameter that is the same as the outer diameter of the annular cast iron ring 1. Three screw holes are arranged in an equilateral triangle shape at a position 12.5 mm away from the outer edge. The hole depth is 4 mm and the hole diameter is 10 mm. The two ends of the stainless steel rod 3 can be inserted into the screw holes of the annular cast iron ring 1 and the circular cast iron plate 2 respectively, so as to achieve the connection effect between the annular cast iron ring 1 and the circular cast iron plate 2.

[0039] Furthermore, a threaded connection portion is provided at one end of the stainless steel rod 3 , and a smooth connection portion is provided at the other end of the stainless steel rod 3 .

[0040] In this embodiment, one end of the stainless steel rod 3 is set to be threaded, and can be screwed into the annular cast iron ring 1 or the circular cast iron plate 2 through the thread, and the other end is set to be smooth, and can be quickly plugged into the annular cast iron ring 1 or the circular cast iron plate 2 through the smooth surface, which is more convenient to operate.

[0041] Furthermore, placing the tamping tool into the lamp pit specifically includes: after installing the stainless steel rod 3 on the circular cast iron plate 2, placing the circular cast iron plate 2 and the stainless steel rod 3 into the lamp pit together.

[0042] In this embodiment, when the tamping tool is placed in the lamp pit, the three stainless steel rods 3 are first screwed into the circular cast iron plate 2 to prevent the mortar from entering the screw holes of the circular cast iron plate 2, making it easier to remove the circular cast iron plate 2; the circular cast iron plate 2 and the stainless steel rods 3 are placed in the lamp pit together, and this step does not require the insertion of the annular cast iron ring 1.

[0043] Furthermore, the tamping construction of the side wall gap of the lamp pit specifically includes: according to the depth of the lamp pit, a layered tamping construction method is adopted; the annular cast iron ring 1 is installed on the stainless steel rod 3, and inserted into the gap of the lamp pit, and the round cast iron plate 2 is inserted and plugged, and then the pad is placed on the pad and hammered to compact. The layered tamping construction method specifically includes: the height of each layer of the layered tamping construction does not exceed 50mm, and the construction is carried out layer by layer until 20mm below the top of the pit, and silicone glue is poured to seal the caulking.

[0044] In this embodiment, a layered tamping construction method is adopted according to the depth of the lamp pit, and the height of each layer in the layered tamping construction does not exceed 50 mm; in the single-layer construction, the annular cast iron ring 1 is screwed into the stainless steel rod 3 and then inserted into the gap, and the circular cast iron plate 2 is inserted on it, and then it is padded with wood and hammered to be dense, and so on, layer by layer is applied until 20 mm below the top of the pit, and the subsequent 20 mm is operated in the same way as usual and silicone glue is poured to seal the seam.

[0045] Furthermore, the side wall of the lamp pit is rammed with dry-mixed mortar, which specifically includes: digging out mortar between the wire inlet hole of the embedded lamp base and the embedded pipe, so that a cavity is formed from the pipe mouth of the embedded pipe to the wire inlet hole of the lamp base.

[0046] In this embodiment, after the dry-mixed mortar on the side wall of the lamp pit is compacted, the mortar between the wire entry hole of the embedded lamp base and the embedded pipe is dug out to form a cavity from the pre-buried pipe mouth to the wire entry hole of the lamp base, which is convenient for later threading and maintenance;

[0047] Since the cable protection tube is pre-buried when the pavement concrete is poured, and the lamp pit is formed by drilling and coring at a later stage, the embedded lamp base and the lamp are installed in the lamp pit. Due to the error between the pre-buried tube construction and the drilling construction, it is inevitably difficult to align the pre-buried tube mouth and the lamp base. The conventional practice is to set a hose transition connection between the pre-buried pipe mouth and the lamp base. However, in the actual construction process, this practice requires a large cost for the sleeve hose, and it will affect the efficacy. Therefore, the construction method of the present application is more efficient and less costly, and can also achieve the same technical effect as the sleeve hose.

[0048] Furthermore, the removing of the tamping tool specifically includes: removing the circular cast iron plate 2 and the annular cast iron ring 1, removing the stainless steel rod 3, cleaning the mud stains on the surface of each component, and naturally drying them for use in the next cycle.

[0049] In this embodiment, the tamping tool can be directly taken out of the lamp pit and disassembled after use, and the mud stains on the surface of each component can be cleaned and naturally dried; the tamping tool is simple to produce, assemble and disassemble, can be reused in different processes, and requires almost no maintenance, which can reduce construction costs.

[0050] Furthermore, the curing of the grouting mortar specifically includes: curing by wet curing, the curing period is not less than three days, and after the curing is completed, it is continuously exposed to sunlight for not less than four days before the silicone glue can be poured in.

[0051] In this embodiment, the grouting mortar is cured by wet curing for no less than three days. After the curing, it is exposed to sunlight for about four consecutive days. After the bottom mortar is completely dry, 20 mm silicone sealant is applied on the top to avoid quality defects such as bulging and cracking of the silicone sealant in the later stage.

The functions of each module in each device in the embodiment can refer to the corresponding description in the above method.
