Description

Technical Field

[0001] The invention relates to the technical field of hydraulic structures, in particular to a tubular storage and filling device for hydraulic mass concrete and application thereof. Background Art

[0002] In the pouring construction of large-volume concrete for hydraulic engineering, it is sometimes necessary to make reserved holes. The commonly used method currently is to use pre-buried PVC pipes to form them. Although this method is simple and easy, there are still the following problems during the pouring process: First, in some construction scenarios, it is necessary to fill the reserved holes with suitable materials and fill them while making holes. The existing PVC pipe hole-making method can only make reserved holes, but cannot fill them while making holes, which has limitations; second, when the vibrating rod vibrates the concrete, the PVC pipe will shift, affecting the position accuracy and causing large deviations; in addition, after the PVC pipe shifts and tilts, it will also increase the difficulty of subsequent pipe extraction, which is easy to cause problems such as pipe breakage.

[0003] The sluice gate is composed of the bottom plate and the piers, and is a large-volume concrete structure of hydraulic engineering. Due to the large volume and complex structure of large-volume concrete, and the fact that concrete is a poor conductor of heat, the heat of cement hydration accumulates inside the structure and is difficult to diffuse. If this heat control problem is not solved well, it is easy to cause cracks in the large-volume concrete; therefore, the main reason for the cracks in the piers is that the tensile stress generated by the temperature change after the concrete solidifies is greater than the ultimate tensile strength of the concrete.

[0004] In response to this problem, some solutions have also appeared in the prior art, such as using low-heat or medium-heat cement during the construction of the gate pier and arranging cold water pipes for water cooling during the pouring process. However, the use of low-heat or medium-heat cement has the problem of high cost and uneconomical; the use of cooling water technology can indeed play a positive role in controlling the cracks in the gate pier concrete, but because the internal temperature of the concrete is high and the temperature of the cooling water pipe is low, the temperature difference between the two is large, resulting in a large temperature gradient. The temperature of the concrete near the water pipe is greatly affected by the change in the cooling water temperature. The large temperature difference between the internal concrete and the pipe wall causes the concrete at the pipe wall to crack early, which will produce several small cracks. The location of the small cracks becomes a weak point. The gate pier will not have problems during the early operation period, but in the later service, under the influence of multiple factors such as the internal stress of the gate pier concrete and the change of ambient temperature during the operation period (especially when encountering a cold wave), the concrete deforms. These small cracks will induce large cracks, destroying the integrity, stability, durability and waterproofness of the structure, affecting normal use. In addition, the cooling water pipe inside the gate pier cannot be pulled out and will be permanently embedded in the gate pier concrete, causing a cavity inside the gate pier, which will affect the integrity of the overall structure, reduce the overall strength of the gate pier, and affect the durability and safety of the sluice gate.

[0005] It can be seen that whether it is low-heat or medium-heat cement or cooling water cooling, there are still some disadvantages. Based on this, how to design a set of effective devices and processes to effectively control the cracks of hydraulic mass concrete structures with a new measure to improve the durability and safety of mass concrete needs further research.

[0084] Embodiment 4:

[0085] Continue to refer to the attached Figure 1 - Fig. 20 This embodiment proposes an application of a tubular storage and filling device for hydraulic mass concrete. The tubular storage and filling device for hydraulic mass concrete is used in sluice crack control, and the steps are as follows:

[0086] S1: Construction preparation: prepare construction plan, determine construction materials and equipment, personnel training, etc.

[0087] S2: Foundation treatment: Before the construction of the gate bottom plate 10 and the gate pier 11, the foundation needs to be treated to ensure the bearing capacity and stability of the foundation.

[0088] S3: Construction of gate bottom plate 10: Binding and installation of skeleton reinforcement 14 ----- Supporting gate bottom plate 10 formwork ----- Concrete pouring ----- Gate bottom plate 10 forming; Among them: S31.

[0091] S42: Binding and installation of pier body reinforcement 15;

[0092] S43: erecting a pier body formwork 17 above the gate bottom plate 10;

[0093] S44: The tubular storage and filling device for hydraulic mass concrete can be detachably installed at the designed position; the tubular storage and filling device for hydraulic mass concrete is temporarily fixed to ensure that the pipe can be removed later;

[0095] S46: Concrete pouring, vibration and curing;

[0096] S47: Filling the outer tube body 1 with the tough material 13;

[0097] S48: After the initial setting of the concrete, the switch 5 is turned on, the airbag 8 is deflated, and the discharge port 7 is opened; the limit is released, and the tubular storage and filling device for hydraulic mass concrete is pulled up and out, and a cavity 12 is formed after being pulled out; while being pulled up, the tough material 13 enters the cavity 12 through the discharge port 7 to fill the cavity 12, thereby achieving filling while pulling out the tube.

[0098] In this embodiment, the tough material 13 includes but is not limited to rubber concrete, acrylic concrete, acrylic rubber concrete, rubber mortar, acrylic rubber mortar. The tough material 13 has good mechanical and deformation properties. The tough material 13 can effectively absorb the temperature deformation energy generated by the hydration of the concrete of the gate pier 11, release temperature stress, reduce stress constraints, and effectively control cracks in the gate pier 11. The tough material 13 is substantially consistent with the strength of the surrounding concrete, and the tough material 13 can effectively absorb the stress generated inside the gate pier 11, ensuring that the maximum stress in the gate pier 11 is less than the ultimate tensile strength of the concrete of the gate pier 11, thereby effectively controlling the generation of cracks in the gate pier 11, ensuring the construction quality, and improving the durability and safety of the project.

[0099] In addition, the tough material 13 cooperates with the steel bars inside the gate pier 11 to form a dual control system of "early prevention + passive defense". First, it can control the occurrence of cracks. Second, even if tiny cracks occur, it can better control the development of tiny cracks inside the gate pier 11 towards large cracks, which is beneficial to the long-term operation of the gate pier 11 and improves durability and safety.

[0105] It should be noted that, in S48, the release of the limit in the above specific method is: release the binding between the cross brace w31 and the pier body steel bar 15, remove the lower pressure piece w3, and then pull out the filling body b, and the support piece w1 is permanently left in the pier body concrete.

[0106] Application results:

[0107] The tubular storage and filling device for hydraulic mass concrete has a wide range of applications. It is not only suitable for sluice construction, but also can be applied to large-volume concrete projects such as concrete gravity dams, reservoirs, and levees. Taking the application to sluice as an example, during the construction of sluice, a tubular storage and filling device for hydraulic mass concrete is used to reserve a cavity 12 inside the gate pier 11, and a tough material 13 is filled in the cavity 12. The tough material 13 is substantially consistent with the strength of the surrounding concrete, and the tough material 13 can effectively absorb the stress generated inside the gate pier 11, ensuring that the maximum stress in the gate pier 11 is less than the ultimate tensile strength of the concrete of the gate pier 11, thereby effectively controlling the generation of cracks in the gate pier 11. Moreover, the construction process of forming holes while filling can ensure that the filled tough material 13 forms a complete whole with the surrounding concrete. The use of this device in the construction of sluices can effectively control the cracks in the gate pier 11, ensure the construction quality, and improve the durability and safety of the project.

[0108] This method is applied to the control of cracks in the sluice. Compared with the process of controlling cracks in the sluice by passing cold water, the construction is simple and the structural integrity can be ensured. In the process of passing cooling water, the cooling water pipe is pre-buried in the concrete of the gate pier 11. The interior of the cooling water pipe is a hollow structure, which makes the internal structure of the gate pier 11 incomplete. However, with this solution, after filling with the tough material 13, there is no cavity inside the gate pier 11, so the structure is complete and the overall strength is guaranteed. Compared with the method of using low-heat or medium-heat cement, the present invention has a low cost for the construction of the sluice and saves costs. This structural design can absorb the internal constraint stress of the gate pier 11 and reduce the constraint stress of the gate bottom plate 10 on the gate pier 11.

[0109] According to the above construction method, a sluice structure with tough material 13 can be obtained. Regarding the structural forms of the cavity 12, there are the following specific ones:

[0110] The first type: the cavity 12 is a fully enclosed structure, both ends of the cavity 12 are closed and completely built into the gate pier 11, see the attached Fig.11 .

[0111] The second type: the cavity 12 is a semi-enclosed structure; the bottom end of the cavity 12 is built into the gate pier 11, which is a closed end; the top end of the cavity 12 extends to the top of the gate pier 11, connected to the outside world, forming an open end, see the attached Fig.12 .

[0112] The third type: the cavity 12 is an open structure, the cavity 12 runs from the bottom of the gate pier 11 to the top of the gate pier 11, and the two ends of the cavity 12 are flush with the bottom and top surfaces of the gate pier 11. See the attached Fig.13 .

[0113] Fourth: Based on any of the above three structural forms, the bottom end of the cavity 12 can also pass through the gate pier 11 and extend into the gate bottom plate 10. See the attached Fig.14 In this embodiment, a stress absorbing layer 16 is provided at the connection between the gate bottom plate 10 and the gate pier 11; the bottom end of the cavity 12 passes through the stress absorbing layer 16. Of course, as another feasible embodiment, the stress absorbing layer 16 may not be provided between the gate pier 11 and the gate bottom plate 10, and the stress absorbing layer 16 may be made of acrylic mortar or rubber aggregate mortar or rubber aggregate mixed with acrylic mortar. The applicant's previous authorized patent text, a method for controlling cracks in a sluice gate pier 11 and a filling device, and the authorization announcement number is CN103882836B.

[0114] In this embodiment, one or more holes 12 may be provided, or one or more rows may be provided. Fig.15 - Fig.17 If multiple rows are used, for example two rows, the holes 12 in two adjacent rows are staggered.

[0115] Test data:

[0116] Example 1: The flood discharge gate of a reservoir is 28 meters long and has 3 holes. Two rows of holes 12 with a hole diameter of 8 cm are set in the gate pier 11. The bottom of the hole 12 extends 0.7 meters into the gate bottom plate 10. The maximum stress in the gate pier 11 is 0.72MPa, which is less than the ultimate tensile strength of the concrete of the gate pier 11, 1.20MPa.

[0117] Example 2: A flood discharge gate of a reservoir is 21 meters long and has two holes. A row of holes 12 with a hole diameter of 10 cm is set in the gate pier 11. The hole 12 extends 0.5 meters into the gate bottom plate 10. The maximum stress in the gate pier 11 is tested to be 0.86 MPa, which is less than the ultimate tensile strength of the concrete of the gate pier 11, 1.16 MPa.

[0118] Example 3: The flood discharge gate of a reservoir is 36 meters long and has 4 holes. Two rows of holes 12 with a hole diameter of 6 cm are set in the gate pier 11. A stress absorption layer 16 with a thickness of 20 cm is set between the hole 12 and the gate bottom plate 10. The maximum stress in the gate pier 11 is 0.67 MPa when tested from the hole 12 to the gate bottom plate 10, which is less than the ultimate tensile strength of the concrete of the gate pier 11, 1.10 MPa.

[0119] Example 4: The flood discharge gate of a reservoir is 42 meters long and has 4 holes. Three rows of holes are set in the gate pier 11, and the hole diameter is 8 cm. A stress absorption layer 16 is set between the gate bottom plate 10 and the gate pier 11. The thickness of the stress absorption layer 16 is 30 cm. The bottom end of the hole cavity 12 extends into the inside of the gate bottom plate 10 by 0.8 meters. The maximum stress in the gate pier 11 is tested to be 0.74 MPa, which is less than the ultimate tensile strength of the concrete of the gate pier 11 of 1.15 MPa.

[0120] It can be seen from the above test data that the present method can effectively absorb the stress in the gate pier 11, ensuring that the maximum stress in the gate pier 11 is less than the ultimate tensile strength of the concrete of the gate pier 11, thereby effectively controlling the generation of cracks in the gate pier 11, ensuring the construction quality, and improving the durability and safety of the project.

[0121] Embodiment five:

[0122] As a feasible embodiment, if necessary, the above construction process can also be added with a cooling water flow step to reduce the temperature inside the concrete. There are two ways to arrange the cooling water pipe, namely plum blossom shape and well shape. In terms of cooling effect, plum blossom shape is better than well shape, because there will be no dead corners that cannot be cooled like well shape, but the working hours are not easy to control, so well shape is often used in engineering. In terms of material, cooling water pipes are mainly metal pipes and plastic pipes. Metal pipes have strong thermal conductivity, good cooling effect, and are almost unaffected by the thickness of the water pipe, but the construction is more complicated. The thermal performance of plastic pipes is poor, and the cooling effect is greatly affected by the thickness of the water pipe wall. The thicker the water pipe wall, the worse the cooling effect, but the construction is relatively simple, and it has been used more and more in engineering in recent years. Therefore, whether to arrange cooling water pipes and how to arrange them is determined according to the actual engineering situation.
