[0002] In the field of building engineering, especially in the field of hydraulic structures and bridge foundations, the pile cap is a key component connecting the upper structure and the lower foundation, and its waterproof performance is crucial. Since the pile cap is often in an area with changing water levels or a high underground water level, it is subject to long-term erosion and penetration of water. If the water stop measures are not appropriate, the pile cap structure will be damaged, affecting the safety and durability of the building.

[0003] Traditional pile cap water stop methods have some limitations. For example, using coiled material waterproofing and other methods, problems such as coiled material damage and loose lap joints can occur during construction, resulting in poor water stop effect.

[0041] In some examples, liquid rubber is used to form the sealing ring 3-1 on the steel pipe pile 1 by dripping, so as to ensure that the sealing ring 3-1 is closely fixed and sleeved on the steel pipe pile 1, and the flow and speed of the liquid rubber are controlled during the dripping process, so as to ensure the thickness and uniformity of the sealing ring 3-1;

[0042] The water stop tray 3-2 is sleeved on the outer side wall of the sealing ring 3-1, so that the water stop tray 3-2 is closely fitted with the sealing ring 3-1, the flat ring 3-3 is installed on the upper end of the water stop tray 3-2, the upper end face of the flat ring 3-3 is formed by dripping liquid rubber to form the fitting ring 3-4, the fitting ring 3-4 is sealed and fitted with the outer wall ring 2-1 of the abutment 2, and the flatness and sealing property of the fitting surface need to be ensured during installation.

[0043] The fitting cover 4-2 is fixedly sleeved on the outer side wall of the water stop tray 3-2, so that it is closely fitted on the water stop tray 3-2, the plug ring 8 of the lower end face of the fitting cover 4-2 is sealed and sleeved with the steel pipe pile 1, which can be achieved by welding or other sealing methods, the bunching cover 4-3 is installed on the upper end face of the fitting cover 4-2, so that the number of the flow discharge holes 4-4 on the inner bottom face of the bunching cover 4-3 is the same as that of the flow guide holes 4-1 and the positions correspond.

[0044] As shown in Figures 1-4 , the sealing ring 3-1 is fixedly sleeved between the steel pipe pile 1, and the fitting ring 3-4 is sealed and fitted between the outer wall ring 2-1.

[0045] For example, as shown in Figure 2 , the outer side wall of the water stop tray 3-2 is fixedly sleeved with the fitting cover 4-2, the fitting cover 4-2 is fitted on the water stop tray 3-2, the upper end face of the fitting cover 4-2 is provided with the bunching cover 4-3, and the inner bottom face of the bunching cover 4-3 is provided with the flow discharge hole 4-4.

[0046] In some examples, the fitting cover 4-2 is used to fit the water stop tray 3-2, which plays a role in strengthening the seal, the gathering cover 4-3 is used to collect the liquid flowing out of the drainage hole on the water stop tray 3-2, and the drainage hole 4-4 is used to drain the gathered liquid.

[0047] For example, as shown in Figure 2 The inside of the gathering cover 4-3 is provided with an intercepting ring 5, which is arranged at the joint of the gathering cover 4-3 and the fitting cover 4-2.

[0048] In some examples, the intercepting ring 5 is installed at the joint of the gathering cover 4-3 and the fitting cover 4-2, which plays a role in sealing interception.

[0052] In some examples, the sealing gasket 7 is used for the sealing splicing of the two circular ring structures of the bearing platform 2.

[0053] For example, as shown in Figure 2 The sealing ring 3-1 and the fitting ring 3-4 are both liquid rubber drops.

[0054] For example, as shown in Figure 2 The number of drainage holes 4-4 is the same as that of the flow guide holes 4-1, and the positions of the drainage holes 4-4 correspond to those of the flow guide holes 4-1.

[0057] In use, when the water level rises to the vicinity of the pile cap 2, the water pressure on the water stop structure increases, at which time the sealing performance of the water stop structure should be closely monitored, especially the parts such as the sealing ring 3-1 and the abutting ring 3-4. If there is slight water seepage, the seepage position and degree should be recorded in time. After the water level drops, it is checked whether the water stop structure is deformed or damaged due to the change of the water level, and the focus is on checking whether the sealing material is dry and cracked, or falls off, etc. If there is a problem, it should be repaired or replaced in time. In addition, the surface of the steel pipe pile 1 is checked to see whether there are problems such as corrosion caused by water erosion, so that appropriate protective measures can be taken.

[0058] The debris on the surface of the pile cap 2 and around the water stop structure should be cleaned in time to avoid damage or affect the drainage of the water stop structure. For the interception ring 5 in the gathering cover 4-3, the intercepted impurities should be cleaned regularly to prevent them from affecting the normal flow of water.
