Description

Technical Field

[0001] The invention relates to the technical field of concrete block construction, and in particular to an underwater positioning method for a block structure and a block structure installation method. Background Art

[0002] During the wharf construction process, large-volume concrete blocks (single block deadweight ≥ 80t) need to be piled up at some locations. It is usually necessary to locate and install the large-volume concrete blocks underwater. When placing the large-volume concrete blocks, it is difficult to ensure the accuracy of the placement if they are directly lowered (the general error is 1-5cm). In the prior art, it is usually necessary to pre-place an auxiliary concrete block, and a steel frame is set on the top of the auxiliary concrete block, and the top of the steel frame is exposed above the water surface. The auxiliary concrete block is accurately placed at the target position by positioning the steel frame. The auxiliary concrete block provides a reference boundary for the placement of the large-volume concrete blocks. The first concrete block is placed according to the formed reference boundary, and the remaining concrete blocks are placed with the placed first concrete block as the reference boundary. In this process, the first concrete block is usually called the initial block or initial concrete block, not only because it is installed first in the existing installation sequence, but also because it can provide a reference boundary condition for subsequent concrete blocks.

[0003] However, during the later actual construction process, those skilled in the art found that the above technical solution has at least the following problems:

[0004] In order to avoid the initial block colliding with the auxiliary concrete block during the installation process, causing a large displacement of the auxiliary concrete block, resulting in the installation accuracy not meeting the use requirements, the auxiliary concrete block is generally designed to be heavier, resulting in a higher manufacturing cost. A lifting ship is required to lift and install it, which is costly. There are not many usage scenarios for it, and it can basically not be reused in the later stage. Summary of the invention

[0005] The purpose of the present invention is to overcome the problem in the prior art that auxiliary concrete blocks are needed to provide a reference boundary for the installation of concrete blocks, but the auxiliary concrete blocks have high cost and low recycling rate, and to provide an underwater positioning method for a block structure and a block structure installation method.

[0006] In a first aspect, the present invention provides a method for underwater positioning of a block structure, comprising installing adjacent initial blocks and first edge blocks; the method comprises the following steps:

[0007] S1. Install the initial block and obtain the first position information of the initial block relative to the first side reference, the initial block installation position is closer to the first side reference than the initial block predetermined position, and there is a gap between the first side reference and the initial block;

[0008] S2. According to the first position information, a first positioning assembly is installed on the initial block so that the first positioning assembly can position the first edge block;

[0009] S3. The first side block is attached to the first positioning assembly;

[0010] S4. Remove the first positioning assembly and place the initial block against the first side block.

[0011] The present invention provides a method for underwater positioning of a block structure. The method comprises the following steps: installing an initial block and obtaining first position information of the installation position of the initial block relative to a first side reference, and then installing a first positioning component on the initial block according to the first position information, so that the first positioning component can position the first side block. At this time, the initial block and the first positioning component can jointly provide a reference boundary in at least one direction for the installation of the first side block; after the first side block is affixed to the first positioning component, the first positioning component is removed. At this time, the first side block can provide a reference boundary in at least one direction for the installation of the initial block. In the method for underwater positioning of a block structure of the present invention, the positioning processes of the initial block and the first side block complement each other, and there is no need to arrange heavy auxiliary blocks to provide a reference boundary in at least one direction for the installation of the initial block and the first side block, which can reduce construction costs and is suitable for a variety of scenarios.

[0012] Preferably, the method further includes installing a second side block adjacent to the initial block; the method includes the following steps:

[0013] A1. In S1, when installing the initial block, the initial block installation position is closer to the second side reference than the predetermined position of the initial block, the second side reference is not parallel to the first side reference, and there is a gap between the second side reference and the initial block;

[0014] A2. Obtaining the second position information of the initial block relative to the second side reference;

[0015] A3. According to the second position information, a second positioning assembly is installed on the initial block so that the second positioning assembly can position the second edge block;

[0016] A4. Place the second side block against the second positioning assembly;

[0017] A5. Remove the second positioning assembly and place the initial block against the second side block.

[0018] In a preferred solution, the above positioning method is used to install a second side block in a direction different from the first side block of the initial block. The second side block can provide a reference boundary in another direction for the initial block. With the joint positioning of the two reference boundaries, the initial block can be accurately positioned on the plane coordinates.

[0019] Preferably, after S2 and A3 are completed, S3 and A4 are performed;

[0020] After S3 and A4 are completed, proceed to S4 and A5.

[0021] Preferably, in S4, when the initial block is placed against the first side block, the initial block installation position is made closer to the second side reference than the initial block predetermined position;

[0022] After S4 is completed, proceed to A2.

[0023] In a preferred solution, after the first side block is abutted against the first positioning component, the position of the initial block is first adjusted so that the initial block abuts against the first side block to achieve positioning in one direction. At this time, the sides of the initial block and the second side block are roughly parallel, and then the second positioning component is installed. This can eliminate the need for adjusting the angle of the second positioning component 121, thereby simplifying the installation steps of the second positioning component and improving the positioning accuracy of the second side block by the second positioning component.

[0024] Preferably, in S3, the first side block is partially extended beyond the predetermined position of the initial block to a side edge close to the second side block, and:

[0025] A4 is located between S3 and S4, and in A4, the second side block is abutted against the second positioning assembly and the first side block;

[0026] or,

[0027] After S4 is completed, A2 is performed, and in A4, the second side block is attached to the second positioning assembly and the first side block.

[0028] The first side block is partially extended out of the initial block to a predetermined position close to the side of the second side block. The extended portion of the first side block and the second positioning assembly can jointly provide reference boundaries in two different directions for the installation of the second side block, so that the second side block can be positioned in two directions on the plane coordinates at the same time, which is conducive to simplifying the construction steps.

[0029] Preferably, the second position information includes the distance between at least two second position points on the initial block and the second side reference, and the relative position relationship between at least two second arrangement points on the initial block and at least one second position point, wherein the second position point is located on a side of the initial block close to the second side reference, and the second arrangement point is located on a side of the initial block close to a predetermined position of the second side block;

[0030] or,

[0031] The first position information includes the distance between at least two first position points on the initial block and the first side reference, and the relative position relationship between at least two first arrangement points on the initial block and at least one first position point, wherein the first position point is located on a side of the initial block close to the first side reference, and the first arrangement point is located on a side of the initial block close to a predetermined position of the first side block,

[0032] The second position information includes the first position information and the distance between at least one second position point and the second side reference, and the relative position relationship between at least two second layout points on the initial block and at least one second position point, wherein the second layout point is located on one side of the initial block close to the predetermined position of the second side block.

[0033] The relative position relationship between the layout points and the position points on the initial block can be obtained by onshore measurement.

[0034] The relative position relationship between the initial block and the first side reference can be obtained based on the distance between at least two first position points and the first side reference [for example, including the deflection angle of the initial block and its distance from the first side reference]. By additionally measuring the distance between at least one second position point and the second side reference, the relative position relationship between the initial block and the second side reference can be obtained.

[0035] Preferably, the first positioning assembly includes at least two first positioning members, and S2 includes the following steps:

[0036] S21. Obtaining the distance between at least two first arrangement points on the initial block and the predetermined position of the first edge block;

[0037] S22. Install a first positioning member facing the predetermined position of the first side block at at least two first arrangement points, wherein the length of the first positioning member is the distance from the first arrangement point to the predetermined position of the first side block.

[0038] Preferably, the second positioning assembly includes at least two second positioning members, and A3 includes the following steps:

[0039] A31. Obtaining the distance between at least two second arrangement points on the initial block and the predetermined position of the second edge block;

[0040] A32. Install a second positioning member facing the predetermined position of the second edge block at at least two second arrangement points, and the length of the second positioning member is the distance from the second arrangement point to the predetermined position of the second edge block.

[0041] The first positioning member and the second positioning member can be made of hard structural members that can be carried by a single person, and the first positioning member and the second positioning member can be installed to the specified position by a diver, thereby simplifying the installation of the first positioning assembly and the second positioning assembly.

[0042] Preferably, the method further comprises the following steps:

[0043] S5. Adjust the first side block so that the side of the first side block close to the second side reference is flush with the initial block;

[0044] and / or,

[0045] A6. Adjust the second side block so that the side of the second side block close to the first side reference is flush with the initial block.

[0046] After accurately positioning the initial block, the first side block and / or the second side block can be accurately positioned by aligning the first side block and / or the second side block with the side of the initial block, thereby providing a reference boundary for the installation of other side blocks through the accurately positioned first side block and / or the second side block.

[0047] Preferably, the first side reference and / or the second side reference is a positioning line, and the positioning line is connected to the base block. When arranging the positioning line, the following steps are included:

[0048] Arrange two base blocks;

[0049] Lower the plumb line, construct positioning points on the two base blocks according to the plumb line, and connect the two positioning points with a positioning rope and tighten it to serve as the positioning line.

[0050] For underwater positioning conditions, a plumb line can be lowered from a ship, the upper end of the plumb line can be located by satellite navigation, and the positioning point can be determined by a diver based on the direction of a weight (e.g., a plumb bob) at the lower end of the plumb line;

[0051] In order to eliminate accidental errors, the positioning can be repeated three times during the construction of the positioning point, and the geometric center of the three initial positioning points can be obtained as the final positioning point.

[0052] In a second aspect, the present invention provides a block structure installation method, using the block structure underwater positioning method as described above to position the initial block.

[0053] The present invention provides a block structure installation method, which uses the block structure underwater positioning method as described above, and can provide reference boundaries in at least two directions for the initial block. Under the common positioning of the two reference boundaries, the initial block can be accurately positioned on the plane coordinates, thereby achieving accurate installation of the initial block. The entire positioning and installation process complements each other, does not require the arrangement of heavier auxiliary blocks, can reduce construction costs, and is suitable for a variety of scenarios.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. The present invention provides an underwater positioning method for a block structure, which comprises installing an initial block and obtaining first position information of the installation position of the initial block relative to a first side reference, and then installing a first positioning component on the initial block according to the first position information, so that the first positioning component can position the first side block. At this time, the initial block and the first positioning component can jointly provide a reference boundary in at least one direction for the installation of the first side block; after the first side block is attached to the first positioning component, the first positioning component is removed. At this time, the first side block can provide a reference boundary in at least one direction for the installation of the initial block; in the underwater positioning method for a block structure of the present invention, the positioning processes of the initial block and the first side block complement each other, and a reference boundary in at least one direction can be provided for the installation of the initial block and the first side block without arranging a heavy auxiliary block, which can reduce construction costs and is applicable to a variety of scenarios;

[0084] Example 1

[0085] This embodiment provides a method for underwater positioning of a block structure, such as Figure 1-3 As shown, it includes installing adjacent initial blocks 1 and first edge blocks 11; it includes the following steps:

[0086] S1. Install the initial block 1 and obtain the first position information of the initial block 1 relative to the first side reference 21. The installation position of the initial block 1 is closer to the first side reference 21 than the predetermined position of the initial block 1. There is a gap between the first side reference 21 and the initial block 1;

[0087] S2. According to the first position information, a first positioning assembly 111 is installed on the initial block 1, so that the first positioning assembly 111 can position the first edge block 11;

[0088] S3. The first side block 11 is placed against the first positioning assembly 111;

[0089] S4. Remove the first positioning assembly 111 and place the initial block 1 against the first side block 11 .

[0090] The installation position of the initial block 1 refers to the position of the initial block 1 in this step, and the predetermined position of the initial block 1 refers to the position of the initial block 1 when it is accurately installed. Similarly, the installation position and predetermined position of the first side block 11, and the installation position and predetermined position of the second side block 12 can be extended.

[0091] The initial block 1 is located between the predetermined position of the first side block 11 and the first side reference 21. When the initial block 1 is installed in S1, the initial block 1 is moved closer to the first side reference 21 than its predetermined position, thereby leaving installation space for the first positioning assembly 111 and the first side block 11. There is a gap between the first side reference 21 and the initial block 1. The gap has at least two functions. One is to prevent the initial block 1 from colliding with the first side reference 21, causing the first side reference 21 to shift and lose its positioning function. The second is to facilitate the subsequent measurement of the distance between the initial block 1 and the first side reference 21.

[0092] The first positioning component 111 is a hard structure component, and one side of the first positioning component 111 can be abutted against the initial block 1, and the other side of the first positioning component 111 can be extended to the predetermined position of the first side block 11, so as to position the first side block 11; after the first positioning component 111 is installed, the first side block 11 is installed, and the first side block 11 is abutted against the first positioning component 111, so that the first side block 11 can be positioned in the direction toward the first side reference 21, and at this time, the side of the first side block 11 facing the first side reference 21 can be used as the reference boundary of the initial block 1, and after the first positioning component 111 is removed, the initial block 1 can be positioned in at least one direction by adjusting the position of the initial block 1 so that the initial block 1 is abutted against the first side block 11.

[0093] The present invention provides a method for underwater positioning of a block structure. The method comprises installing an initial block 1 and obtaining first position information of the installation position of the initial block 1 relative to a first side reference 21, and then installing a first positioning component 111 on the initial block 1 according to the first position information, so that the first positioning component 111 can position the first side block 11. At this time, the initial block 1 and the first positioning component 111 can jointly provide a reference boundary in at least one direction for the installation of the first side block 11; after the first side block 11 is affixed to the first positioning component 111, the first positioning component 111 is removed. At this time, the first side block 11 can provide a reference boundary in at least one direction for the installation of the initial block 1; in the method for underwater positioning of a block structure described in the present invention, the positioning processes of the initial block 1 and the first side block 11 complement each other, and there is no need to arrange heavy auxiliary blocks to provide a reference boundary in at least one direction for the installation of the initial block 1 and the first side block 11, which can reduce construction costs and is suitable for a variety of scenarios.

[0094] In one or more preferred embodiments, the first position information includes the distance between at least two first position points 112 on the initial block 1 and the first side reference 21, and the relative position relationship between at least two first arrangement points 113 on the initial block 1 and at least one first position point 112, wherein, Figure 2 As shown, the first position point 112 is located on a side of the initial block 1 close to the first side reference 21 , and the first arrangement point 113 is located on a side of the initial block 1 close to a predetermined position of the first side block 11 .

[0095] The relative position relationship between the first arrangement point 113 and the first position point 112 on the initial block 1 can be obtained by onshore measurement; it can be understood that the first position point 112 is arranged on one side of the initial block 1 close to the first side reference 21 to facilitate subsequent measurement.

[0096] For example: the distance between the first position point 112 and the first side reference 21 [such as Figure 2 D1 and D2 can be measured by a diver diving to the designated location.

[0097] Based on the distance between at least two first position points 112 and the first side reference 21, the relative position relationship between the initial block 1 and the first side reference 21 can be obtained [for example: including the deflection angle of the initial block 1 and its distance from the first side reference 21], and then by measuring the distance between at least one second position point 122 and the second side reference 22, the relative position relationship between the initial block 1 and the second side reference 22 can be obtained.

[0098] In some cases, the first edge block 11 has at least two mutually inclined side surfaces on one side close to the initial block 1. In this regard, two mutually inclined first positioning components 111 can be installed on the initial block 1. The two first positioning components 111 can respectively position the two mutually inclined side surfaces of the first edge block 11, and provide the first edge block 11 with two reference boundaries in different directions, thereby directly determining the position of the first edge block 11 on the plane coordinates; correspondingly, after the position of the first edge block 11 is determined, the two mutually inclined side surfaces thereon can provide the initial block 1 with two reference boundaries in different directions, thereby directly determining the position of the initial block 1 on the plane coordinates.

[0099] In one or more preferred embodiments, the method for underwater positioning of a block structure further includes installing a second side block 12 adjacent to the initial block 1; the method includes the following steps:

[0100] A1. Install the initial block 1 and obtain the first position information of the initial block 1 relative to the first side reference 21, the installation position of the initial block 1 is closer to the first side reference 21 than the predetermined position of the initial block 1, and there is a gap between the first side reference 21 and the initial block 1, wherein, when installing the initial block 1, the installation position of the initial block 1 is closer to the second side reference 22 than the predetermined position of the initial block 1, the second side reference 22 is not parallel to the first side reference 21, and there is a gap between the second side reference 22 and the initial block 1;

[0101] A2. Obtaining the second position information of the initial block 1 relative to the second side reference 22;

[0102] A3. According to the second position information, a second positioning assembly 121 is installed on the initial block 1, so that the second positioning assembly 121 can position the second edge block 12;

[0103] A4. The second side block 12 is abutted against the second positioning assembly 121;

[0104] A5. Remove the second positioning assembly 121 and place the initial block 1 against the second side block 12 .

[0105] The second side block 12 is installed in a direction different from the first side block 11 using a positioning method similar to that of the first side block 11. The second side block 12 can provide a reference boundary in another direction for the initial block 1. With the joint positioning of the two reference boundaries, the initial block 1 can be accurately positioned on the plane coordinates.

[0106] Those skilled in the art will appreciate that the first side reference 21 and the second side reference 22 may be perpendicular to each other, or may form an acute angle or an obtuse angle, such as Fig.11 and 12 shown.

[0107] In one or several preferred embodiments, the second position information includes the first position information and the distance between at least one second position point 122 and the second side reference 22, and the relative position relationship between at least two second layout points 123 on the initial block 1 and at least one second position point 122, wherein the second layout point 123 is located on one side of the initial block 1 close to the predetermined position of the second side block 12.

[0108] The relative position relationship between the second arrangement point 123 and the second position point 122 on the initial block 1 can be measured on shore; it can be understood that the second position point 122 is arranged on one side of the initial block 1 close to the second side reference 22 to facilitate subsequent measurements. For example, the measurement method can be that a diver dives to a designated position to obtain the measurement.

[0109] Under the condition that the first position information has been obtained, the distance between at least one second position point 122 and the second side reference 22 is additionally measured to obtain the relative position relationship between the initial block 1 and the second side reference 22 [as shown in FIG. Figure 4 D1, D2 and D3].

[0110] In some cases, for example: A2 is performed before S1. Since the first position information has not yet been obtained, the second position information may include the distance between at least two second position points 122 on the initial block 1 and the second side reference 22, and the relative position relationship between at least two second layout points 123 on the initial block 1 and at least one second position point 122, wherein the second position point 122 is located on the side of the initial block 1 close to the second side reference 22, and the second layout point 123 is located on the side of the initial block 1 close to the predetermined position of the second side block 12.

[0111] In some cases, the first position point 112 and the second position point 122 may overlap, for example, the first position point 112 and the second position point 122 are both on the edge where the side edges meet.

[0112] To facilitate the arrangement of the first positioning assembly 111 and the second positioning assembly 121, the first side reference 21 can be parallel to the side of the first side block 11 at a predetermined position close to the initial block 1, and the second side reference 22 can be parallel to the side of the second side block 12 at a predetermined position close to the initial block 1, as shown in FIG. Figure 1 , 11 and 12; there are multiple non-parallel sides, the first side reference 21 or the second side reference 22 is parallel to one of them.

[0113] The first side block 11 and the second side block 12 can jointly provide reference boundaries in at least two different directions for the initial block 1, so that the initial block 1 can be accurately positioned on the plane coordinates. However, this embodiment does not limit the shapes of the first side block 11 and the second side block 12 to regular blocks. The first side block 11, the second side block 12 and the initial block 1 can all be polygonal prisms, stepped components, or a combination of blocks and arcs, etc.

[0114] In one or more preferred embodiments, the first side reference 21 and / or the second side reference 22 is a positioning line, and the positioning line is connected to the base block 2. When arranging the positioning line, the following steps are included:

[0115] Arrange two base blocks 2;

[0128] The length of the second positioning member is set to be the distance from the second arrangement point 123 to the predetermined position of the second side block 12, so that when the second positioning member is abutted against the second arrangement point 123, the other side thereof can extend to the predetermined position of the second side block 12, thereby positioning the second side block 12.

[0129] In one or more preferred embodiments, the method for underwater positioning of a block structure further comprises the following steps:

[0130] S5. Adjust the first side block 11 so that the side of the first side block 11 close to the second side reference 22 is flush with the initial block 1;

[0131] and / or,

[0132] A6. Adjust the second side block 12 so that the side of the second side block 12 close to the first side reference 21 is flush with the initial block 1.

[0136] Step 1: installing the initial block 1, so that the installation position of the initial block 1 is closer to the first side reference 21 than the predetermined position of the initial block 1, there is a gap between the first side reference 21 and the initial block 1, and the installation position of the initial block 1 is closer to the second side reference 22 than the predetermined position of the initial block 1, there is a gap between the second side reference 22 and the initial block 1, and the second side reference 22 is not parallel to the first side reference 21;

[0137] Step 2: Obtain first position information of the initial block 1 relative to the first side reference 21;

[0138] Step 3: According to the first position information, install the first positioning component 111 on the initial block 1, so that the first positioning component 111 can position the first edge block 11;

[0139] Step 4: obtaining second position information of the initial block 1 relative to the second side reference 22;

[0146] For this embodiment: Step 5 can be adjusted between Step 6 and Step 7. On this basis, Step 4 can be performed at any time between Step 1 to Step 5.

[0147] Example 3

[0148] The underwater positioning method of a block structure provided in this embodiment is different from that in Embodiment 1 or 2 in that it preferably includes the following steps:

[0149] Step 1: Install the initial block 1 and obtain first position information of the initial block 1 relative to the first side reference 21. The installation position of the initial block 1 is closer to the first side reference 21 than the predetermined position of the initial block 1. There is a gap between the first side reference 21 and the initial block 1.

[0150] Step 2: According to the first position information, install the first positioning component 111 on the initial block 1, so that the first positioning component 111 can position the first edge block 11;

[0151] Step 3: Place the first side block 11 against the first positioning assembly 111;

[0152] Step 4: remove the first positioning assembly 111, place the initial block 1 against the first side block 11, and make the installation position of the initial block 1 closer to the second side reference 22 than the predetermined position of the initial block 1, with a gap between the second side reference 22 and the initial block 1;

[0153] Step 5: Obtain second position information of the initial block 1 relative to the second side reference 22;

[0154] Step 6: According to the second position information, install the second positioning component 121 on the initial block 1, so that the second positioning component 121 can position the second edge block 12;

[0155] Step 7: Place the second side block 12 against the second positioning assembly 121;

[0156] Step eight: remove the second positioning assembly 121 , and place the initial block 1 against the second side block 12 .

[0157] In this embodiment, after the first side block 11 is abutted against the first positioning assembly 111, the position of the initial block 1 is adjusted so that the initial block 1 abuts against the first side block 11 to achieve positioning in one direction. At this time, the sides of the initial block 1 and the second side block 12 are roughly parallel. Fig.10 As shown, by installing the second positioning component 121 , the angle adjustment of the second positioning component 121 can be omitted, thereby simplifying the installation steps of the second positioning component 121 and improving the positioning accuracy of the second positioning component 121 for the second side block 12 .

[0158] Example 4

[0159] The underwater positioning method of a block structure provided in this embodiment is different from that in Embodiment 1, 2 or 3 in that it preferably includes the following steps:

[0160] Step 1: installing the initial block 1, so that the installation position of the initial block 1 is closer to the first side reference 21 than the predetermined position of the initial block 1, there is a gap between the first side reference 21 and the initial block 1, and the installation position of the initial block 1 is closer to the second side reference 22 than the predetermined position of the initial block 1, there is a gap between the second side reference 22 and the initial block 1, and the second side reference 22 is not parallel to the first side reference 21;

[0161] Step 2: Obtain first position information of the initial block 1 relative to the first side reference 21;

[0162] Step 3: According to the first position information, install the first positioning component 111 on the initial block 1, so that the first positioning component 111 can position the first edge block 11;

[0163] Step 4: obtaining second position information of the initial block 1 relative to the second side reference 22;

[0164] Step 5: According to the second position information, install the second positioning component 121 on the initial block 1, so that the second positioning component 121 can position the second edge block 12;

[0165] Step 6: Place the first side block 11 against the first positioning assembly 111, and allow the first side block 11 to partially extend out of the side edge of the initial block 1 near the second side block 12 at a predetermined position, such as Figure 6 As shown;

[0166] Step 7: Place the second side block 12 against the second positioning assembly 121 and the first side block 11;

[0167] Step 8: Remove the first positioning assembly 111 and place the initial block 1 against the first side block 11;

[0168] Step nine: remove the second positioning assembly 121 , and place the initial block 1 against the second side block 12 .

[0169] For this embodiment: the order of step three and step four is adjustable; the order of step eight and step nine is adjustable.

[0170] For this embodiment: Step 5 can be adjusted between Step 6 and Step 7. On this basis, Step 4 can be performed at any time between Step 1 to Step 5.

[0171] In this embodiment, the first side block 11 is partially extended out of the predetermined position of the initial block 1 close to the side of the second side block 12. The extended portion of the first side block 11 and the second positioning assembly 121 can jointly provide two reference boundaries in different directions for the installation of the second side block 12, so that the second side block 12 can be positioned in two directions on the plane coordinates at the same time, which is conducive to simplifying the construction steps.

[0172] In one or more preferred embodiments, Figure 6As shown, the length of the first side block 11 toward the side of the initial block 1 is greater than the length of the side of the initial block 1 toward the first side block 11 .

[0173] Since the length of the first side block 11 toward the side of the initial block 1 is relatively large, in step six, it is relatively easy to extend part of the first side block 11 out of the predetermined position of the initial block 1 near the side of the second side block 12; and after the positioning and installation are completed, the extended part of the first side block 11 can prevent the second side block 12 from sliding in the direction toward the first side block 11, which is beneficial to the safety of the structure.

[0174] Preferably, the length of the second side block 12 toward the side of the initial block 1 is equal to the length of the initial block 1 toward the side of the second side block 12 .

[0175] Of course, the length of the second side block 12 facing the initial block 1 may be greater than the length of the initial block 1 facing the second side block 12; and the length of the first side block 11 facing the initial block 1 is equal to the length of the initial block 1 facing the first side block 11. In this case, when installing the first side block 11, it is necessary to pay attention that the first side block 11 does not extend out of the side of the initial block 1 predetermined position close to the second side block 12, so as to leave installation space for the second side block 12.

[0176] Example 5

[0177] The underwater positioning method of a block structure provided in this embodiment is different from that in Embodiment 1, 2, 3 or 4 in that it preferably includes the following steps:

[0178] Step 1: Install the initial block 1 and obtain first position information of the initial block 1 relative to the first side reference 21. The installation position of the initial block 1 is closer to the first side reference 21 than the predetermined position of the initial block 1. There is a gap between the first side reference 21 and the initial block 1.

[0179] Step 2: According to the first position information, install the first positioning component 111 on the initial block 1, so that the first positioning component 111 can position the first edge block 11;

[0180] Step 3: Place the first side block 11 against the first positioning assembly 111, and allow the first side block 11 to partially extend out of the side edge of the initial block 1 near the predetermined position of the second side block 12, as shown in FIG. Figure 6 As shown;

[0181] Step 4: remove the first positioning assembly 111 and place the initial block 1 against the first side block 11;

[0182] Step 5: obtaining second position information of the initial block 1 relative to the second side reference 22, where there is a gap between the second side reference 22 and the initial block 1;

[0183] Step 6: According to the second position information, install the second positioning component 121 on the initial block 1, so that the second positioning component 121 can position the second edge block 12;

[0184] Step 7: Place the second side block 12 against the second positioning assembly 121 and the first side block 11;

[0185] Step eight: remove the second positioning assembly 121 , and place the initial block 1 against the second side block 12 .

[0186] In this embodiment, the first side block 11 is partially extended out of the predetermined position of the initial block 1 close to the side of the second side block 12. The extended portion of the first side block 11 and the second positioning assembly 121 can jointly provide two reference boundaries in different directions for the installation of the second side block 12, so that the second side block 12 can be positioned in two directions on the plane coordinates at the same time, which is conducive to simplifying the construction steps.
