Description

Technical Field

[0001] The invention relates to the technical field of civil airport apron ground anchors, and in particular to an implanted split apron ground anchor and a construction method thereof. Background Art

[0002] The apron anchor is an essential part of airport construction and a necessary safety measure for aircraft docking. It is used to moor aircraft or bridges. In case of severe weather such as strong winds, in order to prevent the aircraft from being blown away by the strong wind, the aircraft is generally fixed by towing ropes, wind ropes and anchor structures buried under the apron.

[0003] The main structural forms of existing apron anchors are pit type and cover type. The basic installation method is to embed steel bars in the road surface construction, or drill holes in the existing road surface to insert anchor bars and then backfill with concrete. On this basis, it is divided into two types of anchors according to whether the anchor cover is set. The characteristics and construction methods of pit type and cover type anchors are as follows:

[0004] The pit type ground anchor is composed of anchor bars, steel mesh and pits on the pavement that are pre-buried or installed later. The anchor bars are in the shape of "Ω" and are welded to the steel mesh to form a whole. Then they are locked and anchored with the pavement concrete to play a role. In order to keep the pavement surface flat and install the mooring rope, a pit with a width of 15~20cm and a depth of 10~15cm is generally reserved on the pavement to expose the anchor ring. When constructing the pit type ground anchor, firstly, the site is set out and positioned, and then the pre-made anchor bars and steel mesh are placed in the predetermined position together with the steel mesh. After adjusting the elevation and angle, they are initially fixed, and finally concrete is poured. When plastering, a pit is dug at the top of the anchor bar (i.e. the anchor ring). In the case of installing a pit type ground anchor on an existing pavement, first drill or cut a hole at the corresponding position, and remove the concrete. The excavation size should be sufficient to allow the anchor bars and steel bars to be placed smoothly. Then the anchor bars and steel bars are placed, and finally concrete is poured, leaving a pit for the anchor ring position.

[0005] The capped ground anchor is an improvement on the trench ground anchor. Its purpose is to eliminate the safety risks that the anchor pit brings to daily workers, which is mainly achieved by installing an anchor cover on the top surface. The construction of the capped ground anchor generally directly welds the anchor cover to the steel mesh and installs it in the way of pre-buried into the road surface in the same way as the trench ground anchor construction, but without leaving a trench. When renovating the existing ground anchor, a hole is drilled on the road surface. The diameter and depth of the hole are determined according to the size of the anchor cover, and then the anchor cover is installed, and mortar or polymer is backfilled around the anchor cover to fix it.

[0006] At present, in the process of using ground anchors, it is found that the existing technology has the following problems: the pit type ground anchor brings safety hazards to the maintenance personnel on the apron due to the existence of the pit, and the exposed steel bars are prone to rust; although the cover type ground anchor solves the pit safety problem of the pit type ground anchor, its installation process depends on high-precision pre-embedded positioning, the construction is difficult, and the anchor cover is often unable to be opened due to freezing during the low temperature season in winter and spring in the north. Both require the embedding of huge anchor bars, and cannot be installed near the position of the concrete road slab seam, nor can they meet the installation requirements on thinner road surfaces; limited by the size of the pit or the anchor cover, the mooring rope cannot be quickly fixed to the anchor ring during the mooring operation, and friction occurs at the edge of the pit or the edge of the anchor cover, damaging the mooring rope; the existing ground anchors all rely on the anchoring between the steel bar and the concrete slab to play a role, and are not suitable for asphalt pavements.

[0095] Specifically, according to the marks that have been made, first use a coring machine to drill the upper section. The diameter of the drill bit used should match the size of the anchor seat or be slightly larger than the size of the anchor seat. The upper drilling depth is slightly larger than the height of the anchor seat. After the upper drilling is completed, clean up the broken pavement concrete or asphalt mixture. Secondly, use a drilling rig to drill the lower section. The diameter of the lower drilling hole meets the requirement for the smooth insertion of the anchor rod body and the grouting pipe. The total drilling depth should be slightly larger than the total height of the anchor rod body and the anchor seat body. During the drilling process, pay attention to the observation of the foundation soil condition and check it in time with the survey conclusion. If there is a large deviation, the anchor rod length needs to be redesigned. After the drilling construction is completed, measure the borehole diameter and depth, and finally clean the hole.

[0096] S3: Assemble the anchor rod assembly 3, apply an anti-corrosion coating layer on the anchor rod body 31, install a protective sleeve, and tie a grouting pipe 5 along the axial direction of the anchor rod body 31.

[0097] Specifically, the steel strands of the rod body are cut mechanically according to the design requirements, butter is applied to the anchor rod body 31, and a PVC plastic tube is put on and sealed to form an anti-adhesion and anti-corrosion isolation protective layer. A steel strand connector is used to connect the rod body and the carrier 32 at one end of the anchor rod body 31, and a temporary protective cover is put on after the other end is connected to the steel strand connector. The protective cover should be able to ensure that it will not be damaged or fall off during the construction process. After the assembly is completed, the grouting pipe is tied, and the end of the grouting pipe is close to the carrier. The tying can be done by iron wire or other methods.

[0098] S4: Place the anchor assembly 3, vertically place the tied anchor rod body 31 and the grouting pipe 5 into the borehole, adjust the height of the anchor rod body 31 to the installation height, and the center of the anchor rod body 31 should be located in the center of the borehole. After placement, take temporary fixing measures such as wedge plugging.

[0099] S5: Grouting: After the anchor assembly 3 is put into the hole, a grouting machine is used for grouting. The grouting material is cement mortar prepared by yourself or purchased. 24 hours after the grouting is completed, clean the floating slurry in the borehole.

[0100] S6: Install the anchor assembly 2. Installing the anchor assembly 2 includes cleaning the surface after the grouting strength reaches no less than 70% of the design strength; installing the anchor body 22, and filling the gap between the anchor body 22 and the pavement structure layer with high-strength polymer mortar 8, with a filling height of 2 to 3 cm from the pavement surface; placing a protective cover at the construction location to prevent damage, and installing the fastening nut connecting the first connector 311 and the anchor body 22 after the high-strength polymer mortar 8 forms strength; after installation in place, apply waterproof glue at the connection between the fastening nut and the anchor body. Check the anchor cover plate 21, and install the cover plate 21 and the bottom support plate 23 after confirming that it is normal. Finally, use weather-resistant caulking material 9 to fill the remaining gap between the anchor body 22 and the pavement structure layer.

Specifically, connect and disassemble the filling device 4 and the anchor ring assembly 1, simulate mooring and other operations, place the filling device, store the anchor ring assembly 1 in a specified place, and the construction is completed.

[0103] The implanted split apron ground anchor provided in this embodiment adopts an implanted installation method, does not require large pre-embedded steel bars, has a small plane size, alleviates the position conflict between the ground anchor and the cement concrete road slab seam, helps to accurately locate and install the ground anchor, and simplifies the road surface construction process. The ground anchor has no pits and no movable anchor cover, which solves the operational safety problems and anchor bar corrosion problems of the pit-type ground anchor, and solves the problem that the cover of the ground anchor cannot be opened due to freezing in severe cold areas. The concrete 10 around the anchor rod assembly 3 is used to form an interlock with the foundation, which does not rely on the anchoring effect between the steel bars and the concrete slab on the ground. It has a wide range of applications and is suitable for both cement road surface installation and asphalt road surface installation. It can play a role in both new and existing road surfaces. The mooring load is directly transmitted to the foundation, and the bearing body at the end and the anchor rod coated with an isolation layer make the concrete around the ground anchor in a compressed state, and no cracks will be generated due to the tension of the mooring load, thereby improving the durability of the structure. The operation is simple and safe, and the all-round movable anchor ring can achieve rapid mooring at any angle, and the reflective coating helps to play a warning role at night.

[0104] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
