[0002] The ship lock is a navigation structure widely used in inland waterways for ships to overcome the concentrated water level difference. The ship lock is mainly composed of upper and lower lock heads, lock chambers and water delivery systems. When ships pass through the ship lock, they need to use the water delivery system to repeatedly fill and discharge water in the lock chamber to overcome the concentrated water level difference of the lock, and ultimately ensure the safety of ship berthing and navigation. In the process of repeated water delivery in the ship lock, in order to consume the large amount of energy brought by the water flow entering the lock chamber and meet the berthing conditions of ships in the lock chamber, various water delivery corridors with water outlets are often arranged in the lock chamber to adjust the flow distribution.

[0003] In the related art, a steel template matching the size of the water outlet is usually used for casting, and the steel template is demoulded after casting to form the water outlet. However, this method is difficult to demould.

[0007] When pouring the water outlet of the ship lock water delivery gallery, the support plate is fixed between the first steel formwork and the second steel formwork;

[0008] When the water outlet of the water delivery gallery of the ship lock is poured, the support plate is separated from the first steel formwork and the second steel formwork to realize the removal of the first steel formwork and the second steel formwork.

[0036] See also Figure 2In one embodiment of the utility model, a first socket 4 is provided on the top of the first steel template 1 and the second steel template 2, and a first opening 31 is provided on the upper part of the support plate 3.

[0037] In this embodiment, by setting the first socket 4 on the top of the first steel formwork 1 and the second steel formwork 2, and setting the first opening 31 on the upper part of the support plate 3, it can be ensured that the first pin 5 can be inserted into the first socket 4 and the first opening 31, thereby achieving the fixation of the support plate 3, the first steel formwork 1 and the second steel formwork 2, and then ensuring the stability of the steel formwork during the pouring process.

[0038] See also Figure 4 In one embodiment of the utility model, a second socket 6 is provided at the bottom of the first steel formwork 1 and the second steel formwork 2, and a second opening 32 is provided at the lower part of the support plate 3.

[0040] See also Figure 3 In one embodiment of the present invention, the first opening 31 and the second opening 32 are both strip-shaped openings.

[0041] In this embodiment, by setting both the first opening 31 and the second opening 32 as strip-shaped openings, the convenience of installation can be ensured and the removal can be better achieved by shaking the support plate 3 (i.e., separation from between the first steel template 1 and the second steel template 2).

[0042] See also Figure 4 In one embodiment of the utility model, the first steel template 1 includes a first arc segment 11, a first straight segment 12 and a second arc segment 13 connected in sequence, the first arc segment 11, the first straight segment 12 and the second arc segment 13 are all detachably connected, and the recessed direction of the first arc segment 11 and the second arc segment 13 is away from the second steel template 2.

[0043] In this embodiment, by setting the arc segment, it can be ensured that water flows into and out of the outlet quickly, and the pouring quality can be improved by squeezing concrete; by setting the first arc segment 11, the first straight segment 12 and the second arc segment 13, the convenience of dismantling the first steel formwork 1 can be ensured.

[0044] Please continue reading Figure 4 In one embodiment of the utility model, the second steel template 2 includes a third arc segment 21 and a second straight segment 22 connected in sequence, the first arc segment 11 and the third arc segment 21 are opposite, the first straight segment 12 and the second straight segment 22 are opposite, the second arc segment 13 and the second straight segment 22 are opposite, the concave direction of the third arc segment 21 is away from the second steel template 2, the corresponding position of the first arc segment 11 and the third arc segment 21 is the outlet of the water outlet, and the corresponding position of the bottom of the second arc segment 13 and the second straight segment 22 is the inlet of the water outlet.

[0045] In this embodiment, by setting the third arc segment 21, it can be ensured that water flows out of the outlet quickly, and the pouring quality can be improved by squeezing concrete; by setting the second straight segment 22, the position corresponding to the bottom of the second arc segment 13 and the second straight segment 22 is the entrance of the outlet, which can ensure that the water flow will not collide when flowing into the outlet, that is, the water flow will flow into the outlet through the area where the third arc segment 21 is located, and then hit the bottom of the second straight segment 22, so that it can quickly flow into the outlet.

[0046] Please continue reading Figure 4 In one embodiment of the utility model, the first arc segment 11, the second arc segment 13 and the third arc segment 21 are all provided with planes, the first socket 4 is provided on the planes of the first arc segment 11 and the second arc segment 13, and the second socket 6 is provided on the plane of the third arc segment 21 and on the bottom surface of the second straight line segment 22.

[0047] In this embodiment, by setting planes on the first arc segment 11, the second arc segment 13 and the third arc segment 21, the first socket 4 is set on the planes of the first arc segment 11 and the second arc segment 13, which can ensure the stability of the installation of the first socket 4.

[0048] See also Figure 3 and Figure 4 In one embodiment of the utility model, the support plate 3 is a wedge-shaped structure, and the thickness of the support plate 3 along the demoulding direction becomes larger and larger;

[0049] The widths of the portions where the first straight line segment 12, the support plate 3 and the second straight line segment 22 are in contact are equal.

[0050] In this embodiment, the support plate 3 is wedge-shaped, and the thickness of the support plate 3 along the demoulding direction is increasing, which is conducive to the demoulding of the support plate 3; the width of the part where the first straight line segment 12, the support plate 3 and the second straight line segment 22 are attached is equal (i.e. Figure 4 The width of the area where the height h2 is located is equal), so that the discharge of water flow can be guaranteed without increasing the kinetic energy; and at the water outlet position, the first arc segment 11 and the third arc segment 21 are set to ensure that the volume of water flow increases and the kinetic energy decreases when it is discharged, thereby not causing a large impact on the ship.

[0051] Please continue reading Figure 1 In one embodiment of the utility model, a wedge plate 23 is provided in the middle part of the second steel template 2. The wedge plate 23 is an integrally formed structure. The wedge plate 23 includes an arc segment and a straight segment. The width of the wedge plate 23 along the demoulding direction becomes larger and larger.

[0052] In this embodiment, by providing a wedge plate 23 in the middle portion of the second steel template 2 , it is possible to make it easier to demould the wedge plate 23 from the second steel template 2 , thereby facilitating demoulding of the second steel template 2 .

[0053] In one embodiment of the present invention, the outer surface of the support plate 3 is coated with lubricating oil, which is beneficial for demoulding the support plate 3 .

[0054] In some embodiments, the first steel formwork 1, the second steel formwork 2 and the support plate 3 all adopt a hollow rib plate structure, which is lighter and more convenient to load and unload than a solid steel structure.

[0055] See also Figure 3 and Figure 4 It should be noted that the inventors found during the research and development process that the three heights of the first steel template 1 and the second steel template 2 in the height direction (i.e., the height h1 of the first arc segment 11 and the third arc segment 21, the height h2 of the first straight segment 12 and the height h3 of the second arc segment 13, and the height of the second straight segment 22 is equal to h2+h3) and the widths of the upper and lower surfaces of the support plate 3 (i.e., the width w1 of the upper surface and the width w2 of the lower surface) determine the demoulding difficulty of the steel template to a certain extent. At the same time, considering the relevant dimensional constraints of the actual installation, the above-mentioned height parameters and width parameters can take into account the dual advantages of easy demoulding and convenient installation when satisfying the following formula group, that is, the dimensional parameters of the first steel template 1, the second steel template 2 and the support plate 3 are constrained by the following formula:

[0056] 4×(w1-w2)≤h1+h2+h3≤5×(w1-w2)

[0057] h1+h3≤h2≤2×(h1+h3)

[0058] 1.5×w2≤w1≤2×w2

[0059] 1.1×h1≤h3≤1.2×h1

[0060] Among them, "4×(w1-w2)≤h1+h2+h3≤5×(w1-w2)" can ensure that the installation of the first steel template 1, the second steel template 2 and the support plate 3 is more convenient, and "h1+h3≤h2≤2×(h1+h3)" can ensure that the demoulding of the first steel template 1 and the second steel template 2 is easier.

[0061] “1.5×w2≤w1≤2×w2” can ensure that the support plate 3 is easier to demould, and “1.1×h1

[0062] ≤h3≤1.2×h1” can ensure that the water outlet is smoother when water flows in.

[0063] The following describes the construction method of the above steel formwork:

[0064] S1, assemble the first arc segment 11, the first straight segment 12 and the second arc segment 13 to form the first steel template 1, assemble the third arc segment 21 and the second straight segment 22 to form the second steel template 2 (wherein the wedge plate 3 has also been formed in the second steel template 2 at this time), insert a plurality of (for example, five) support plates 3 into the first steel template 1 and the second steel template 2, and insert a plurality of pins into the sockets of the steel templates and the openings of the support plates 3, thereby completing the overall construction of the steel template;

[0065] S2. pouring concrete between every two adjacent steel formworks;

[0066] S3. When the pouring operation is completed, first pull out the multiple pins from the sockets of the steel template and the openings of the support plates 3, and then pull out the multiple support plates 3 along the demoulding direction; then pull out the wedge plate 23 from the second steel template 2 (i.e. demoulding), and then pull out the first arc segment 11 and the third arc segment 21 (i.e. demoulding); then pull out a first straight line segment 12 and two second straight line segments 22, and finally pull out the second arc segment 13, thereby completing the overall demoulding of the steel template, that is, the location of the steel template forms the outlet of the water conveyance corridor of the ship lock.

[0067] In summary, the above technical solution has the following technical features:

[0068] 1. Compared with traditional wooden formwork, this formwork has many advantages such as high turnover, low cost and good concrete surface quality. To solve the problem of difficult demoulding of traditional formwork, we abandoned the traditional demoulding process and adopted a new "segmented support and segmented dismantling" construction process. Through on-site tests, we effectively solved the problem of supporting and dismantling the outlet of the water supply corridor.

[0069] 2. The previous steel formwork construction process also had the problem of demoulding difficulties. After many communications with the construction project team, our technical team proposed the demoulding concept of "dismantling part first" in combination with related similar construction processes and the characteristics of this project. Under the condition of limited construction space, it can meet the construction requirements and various technical indicators such as construction specifications and dimensions.

[0070] 3. For the demoulding module, we use an integral welding process, which can not only meet the welding strength requirements, but also meet the overall rigidity requirements of the demoulding module, thus laying a technical guarantee for the size requirements of the outlet. By applying demoulding lubricant, the demoulding of the first part can be ensured to be smooth, providing space guarantee for the smooth demoulding of the whole template in the next step.

[0071] 4. This new type of outlet template is designed with limit devices (i.e. latches) at the upper and lower openings. The limit devices can effectively control the overall stability, rigidity and strength requirements of the outlet template of the water delivery corridor.

[0072] 5. The side formwork (i.e. the second steel formwork) was adjusted from an integral type to a segmented type to improve demoulding efficiency and reliability. The test results showed that the expected effect was achieved, which once again innovated the design concept of the outlet formwork and provided technical and practical guarantees for subsequent process innovations.

[0073] It should be noted that, in the present invention, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] Finally, it should be noted that the above is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model are included in the protection scope of the utility model.
