Description

Technical Field

[0001] The utility model relates to the technical field of open caisson construction, in particular to a horizontal control device suitable for open caissons. Background Art

[0002] For the horizontal control of the cast-in-situ open caisson during excavation and sinking, generally, a level instrument is used for measurement and control, or a lime line is drawn on the open caisson, and the horizontal control is carried out according to the distance relationship between the lime line and the ground. When using a level instrument for measurement and control, it is necessary to measure after each sinking, and it may also be affected by surface obstacles, which is time-consuming, laborious, and costly; when using a lime line drawn on the open caisson, the measurement accuracy of the distance from the ground is relatively low, it is not easy to control, and it is necessary to re-measure and set out after each sinking, resulting in a high labor cost. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problems that the existing horizontal control means for the cast-in-situ open caisson during excavation and sinking are time-consuming, laborious, and have a high labor cost during the measurement after each sinking, and to provide a horizontal control device suitable for open caissons.

[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0005] A horizontal control device suitable for open caissons includes a first pipe body arranged circumferentially. The first pipe body is used to be arranged along the circumference of the open caisson. The first pipe body is communicated with a plurality of vertically arranged second pipe bodies. The second pipe bodies are evenly spaced along the circumference of the first pipe body. The second pipe bodies are transparent components, and liquids are used to be contained in the second pipe bodies.

[0006] During use, the openings of the second pipe bodies face upward to facilitate containing liquids. The number of the second pipe bodies is determined according to the cross-sectional shape and size of the open caisson to be sunk and the accuracy requirements.

[0007] When using the horizontal control device suitable for open caissons according to the utility model, there are liquids in the second pipe bodies. Since the first pipe body connects a plurality of second pipe bodies, by connecting the first pipe body to the open caisson, the relative height difference between the liquid levels in each second pipe body and the upper opening of the open caisson can be observed through the transparent second pipe bodies, so as to quickly judge the attitude of the open caisson. If the relative height differences at each position are the same, the attitude of the open caisson meets the requirements; if there are differences in the height differences, the attitude needs to be further adjusted. The device has a simple structure and convenient operation. After each sinking of the open caisson, it can be used for the horizontal attitude control of the open caisson sinking without re-arrangement. The accuracy is relatively high, which can effectively meet the needs of settlement construction, the cost is low, and it can be reused, which is beneficial to energy conservation and environmental protection.

[0008] Preferably, scales are provided on the second pipe bodies.

[0009] It is convenient to obtain attitude adjustment data more intuitively.

[0010] Preferably, the first pipe body is provided with a tee joint, and the second pipe body communicates with the first pipe body through the tee joint.

[0011] Preferably, the first pipe body is connected to the caisson through a hook.

[0012] It is convenient to install the whole device on the caisson.

[0013] Further preferably, a limiting ring is arranged outside the second pipe body, a connecting piece is arranged on the limiting ring, one end of the connecting piece is connected to the first pipe body, and the other end has the hook.

[0014] Preferably, the shape of the first pipe body adapts to the shape of the caisson.

[0015] Preferably, the first pipe body is arranged on the outer wall of the caisson.

[0016] Preferably, when the caisson is polygonal, each side of the caisson has at least two second pipe bodies, and each corner of the caisson has the second pipe body.

[0017] Further preferably, the first pipe body comprises a plurality of pipe segments, each pipe segment corresponds to the corresponding side of the caisson, and there is a break between two adjacent pipe segments.

[0018] It is also possible to only form a connection for all the second pipe bodies on each side.

[0019] Further preferably, the first pipe body is a flexible pipe, and the second pipe body is a glass pipe or a PVC pipe.

[0020] The first pipe body adopts a flexible pipe, which is beneficial to reducing the requirement of processing precision and is also beneficial to the repeated use of caissons with different cross-sectional shapes.

[0021] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0022] 1. By using a horizontal control device for a caisson according to the present utility model, the relative height difference between the liquid levels in each second pipe body and the upper opening of the caisson can be observed through the transparent second pipe body, so as to quickly judge the attitude of the caisson. If the relative height differences at each position are the same, the attitude of the caisson meets the requirements. If there are differences in the height differences, the attitude needs to be further adjusted. The device has a simple structure and convenient operation. After each sinking of the caisson, it can be used for the horizontal attitude control of the caisson sinking without re-arrangement, with relatively high precision, can effectively meet the needs of settlement construction, has low cost, can be reused, and is beneficial to energy conservation and environmental protection.

Embodiment

[0033] A horizontal control device applicable to a caisson adopted in this embodiment, as Figure 1-2 shown, includes a first pipe body 1 arranged circumferentially. The first pipe body 1 is used to be arranged circumferentially along the caisson 0. A plurality of vertically arranged second pipe bodies 2 are communicated with the first pipe body 1. The second pipe bodies 2 are evenly spaced along the circumferential direction of the first pipe body 1. The second pipe bodies 2 are transparent components, and the inside of the second pipe bodies 2 is used to hold liquid.

[0034] In some embodiments, the cross-sectional shape of the caisson 0 can be rectangular, circular, polygonal, etc. The number of the second pipe bodies 2 is determined according to the cross-sectional shape, size, and accuracy requirements of the caisson 0 to be settled. Figure 1 The second pipe bodies 2 located on the left side and the back side of the caisson 0 are not shown.

[0035] In some embodiments, the second pipe bodies 2 can be provided with scales, and the accuracy of the scales is determined according to the accuracy control requirements of the caisson 0.

[0036] In some embodiments, the first pipe body 1 is provided with a tee joint 3, and the second pipe bodies 2 can be communicated with the first pipe body 1 through the tee joint 3, as Figure 2 shown.

[0037] In some embodiments, the first pipe body 1 is connected to the caisson 0 through a hook 4. The hook can be directly arranged on the first pipe body 1, or can be connected through some means such as a connecting plate.

[0038] In some embodiments, a limiting ring 5 may be provided outside the second pipe body 2. A connecting member is provided on the limiting ring 5. One end of the connecting member is connected to the first pipe body 1, and the other end has a hook 4. The hook 4 is hooked on the top surface of the caisson 0, as Figure 1-2 shown.

[0039] In some embodiments, the shape of the first pipe body 1 is adapted to the shape of the caisson 0, as Figure 1 shown. Of course, for a caisson 0 with a square cross-section, the first pipe body 1 with a circular ring structure may also be used.

[0040] In some embodiments, the first pipe body 1 may be provided on the outer wall of the caisson 0 or on the inner wall of the caisson 0.

[0041] In some embodiments, when the caisson 0 is polygonal, each side of the caisson 0 has at least two second pipe bodies 2, and each corner of the caisson 0 has a second pipe body 2. As shown in 1, the cross-section of the caisson 0 is rectangular, and two second pipe bodies 2 are provided on each side of the rectangle ( Figure 1 the second pipe bodies 2 on the left side and the back in

[0042] are not shown), and three, four, etc. may also be set. Among them, the second pipe bodies 2 need to be provided at the corners of each side, that is, there are second pipe bodies 2 near the corners of each side. Figure 1 In some embodiments, the first pipe body 1 includes several pipe segments, each pipe segment corresponding to the corresponding side of the caisson 0, and the adjacent two pipe segments are disconnected.

The liquid level during filling is lower than the pipe orifices. The relative height difference between the liquid levels in each second pipe body 2 and the upper opening of the caisson 0 can be observed through the transparent second pipe body 2, so as to quickly judge the attitude of the caisson 0. If the relative height differences at each position are the same, the attitude of the caisson 0 meets the requirements. If there are differences in the height differences, the attitude can be further adjusted according to the specific height difference differences. The device has a simple structure and convenient operation. After each sinking of the caisson, it can be used for the horizontal attitude control of the caisson sinking without re-arrangement, with relatively high precision, can effectively meet the needs of settlement construction, has low cost, can be reused, and is beneficial to energy conservation and environmental protection.
