Description

Technical Field

[0001] The utility model relates to the technical field of vacuum devices, in particular to an automatic floating and sinking vacuum device. Background Art

[0002] In engineering practice, the traditional and effective method for reinforcing soft soil foundation is the preloading method. However, due to the lack of sources of loading materials, tight transportation, and difficult turnover, the construction progress is directly affected, resulting in a long construction period and high engineering costs. For this reason, vacuum preloading methods are used at home and abroad to solve the problems of insufficient loading materials and long construction periods. However, with the improvement of reinforcement requirements, vacuum preloading methods cannot meet the needs of engineering practice. Therefore, the construction method of vacuum combined with preloading for treating soft soil foundations was created.

[0003] At present, when the vacuum combined with preloading construction method is applied, a vacuum tank combined with a pump suction device is used to extract water from the soft soil foundation, and a waterproof material is laid on the soft soil foundation. The vacuum tank is placed on the soft soil foundation, and the extracted water is discharged on the soft soil foundation, that is, the soft soil foundation is compacted by the water in the soft soil foundation itself. However, as the water on the soft soil foundation is loaded to a certain height (sometimes the water depth can even reach 2 meters), the vacuum tank may be submerged and the electrical facilities of the vacuum tank may be damaged. Therefore, a metal support platform is currently used to be placed under the vacuum tank to raise the position height of the vacuum tank. However, since the water depth is different during each construction, and the difference in water depth can even reach more than 1 meter, it is difficult to design the height of the metal support platform in advance to a suitable height. When a relatively high metal support platform is pre-set, the greater the height difference between the vacuum tank and the ground, the lower the water extraction efficiency, which makes it difficult to perform the performance of the suction device. Therefore, the efficiency of the vacuum combined with preloading construction is lost. Utility Model Content

[0004] In view of this, the utility model proposes an automatic floating and sinking vacuum device, which can at least to a certain extent solve the problem of loss of efficiency in vacuum combined loading preloading construction.

[0010] As a further optional scheme for the automatic floating and sinking vacuum device, the first guide structure is a guide rod vertically arranged on the support platform, and the second guide structure is a ring arranged on the outside of the vacuum tank, and the ring is slidably connected to the guide rod.

[0011] As a further optional solution of the automatic floating and sinking vacuum device, it also includes a stainless steel tie, the stainless steel tie hoop is arranged on the outer periphery of the vacuum tank, and the ring is welded to the tie.

[0017] The beneficial effects of the utility model are as follows: the buoyancy carrier is utilized to enable the vacuum tank to float up and down with the height of the water cover, so that the vacuum tank is kept not immersed in water and at the same time not too far away from the ground, which can avoid safety accidents and equipment damage on the one hand, and avoid unnecessary performance loss on the other hand; in addition, the first guide structure and the second guide structure are utilized to maintain the stability of the vacuum tank when it floats up and down, ensuring that the vacuum tank has a stable posture and can work stably.

[0030] refer to Figure 1-3 An embodiment of the present application shows an automatic floating and sinking vacuum device, including a support platform 1, a vacuum tank 2 and a buoyancy carrier 3; the support platform 1 is provided with a first guide structure; the vacuum tank 2 is mounted on the support platform 1, and a second guide structure is provided on the vacuum tank 2, and the second guide structure forms a vertical sliding fit with the first guide structure; the buoyancy carrier 3 is arranged at the bottom of the vacuum tank 2.

[0031] Among them, the buoyancy carrier 3 is used to enable the vacuum tank 2 to float up and down with the height of the water cover, so that the vacuum tank 2 is kept not immersed in water and not too far away from the ground. On the one hand, safety accidents and equipment damage can be avoided, and on the other hand, unnecessary performance losses can be avoided. In addition, the first guide structure and the second guide structure are used to maintain the stability of the vacuum tank 2 when it floats up and down, ensuring that the vacuum tank 2 has a stable posture and can work stably.

[0032] Conventionally, the vacuum tank 2 is provided with a suction pipe (not marked in the figure) for pumping water from the soft soil foundation, a drainage pipe (not marked in the figure) for discharging the pumped water, and an air extraction pipe (not marked in the figure) for connecting a pump (not shown). The working principle and specific structure of the vacuum tank 2 can refer to the prior art, so it will not be described in detail.

[0033] In some embodiments, Figure 2 As shown, the first guide structure is a guide rod 11 vertically arranged on the support platform 1, and the second guide structure is a collar 21 arranged on the outside of the vacuum tank 2, and the collar 21 is slidably sleeved on the guide rod 11. In this way, when the overlying height rises and the buoyancy carrier 3 and the vacuum tank 2 float up, the collar 21 slides along the guide rod 11, so that the vacuum tank 2 keeps moving vertically upward during the floating process, avoiding the vacuum tank 2 from flipping over, etc., thereby ensuring the stability of the vacuum tank 2.

[0034] In some embodiments, Figure 2The vacuum tank 2 further comprises a stainless steel tie 22, which is clamped around the outer periphery of the vacuum tank 2, and the collar 21 is welded to the tie. Thus, in this embodiment, the stainless steel tie 22 is used as an intermediate connection between the collar 21 and the vacuum tank 2, so as to avoid the collar 21 being fixed to the vacuum tank 2 by bolt connection, welding, etc., thereby avoiding damage to the structure of the vacuum tank 2; in addition, the stainless steel tie 22 has a low cost, and the stainless steel tie 22 is easy to fix to the vacuum tank 2, and the fixing effect is good.

[0035] Specifically, in order to further improve the stability of the vacuum tank 2 floating up and down, refer to Figure 2 There are two guide rods 11, which are respectively arranged on both sides of the support platform 1, and the vacuum tank 2 is located between the two guide rods 11; at least two stainless steel ties 22 are provided on the vacuum tank 2, and the two stainless steel ties 22 are vertically distributed on the vacuum tank 2, and each stainless steel tie 22 has two rings 21, and the two rings 21 on the stainless steel tie 22 correspond to the two guide rods 11 respectively.

[0036] Specifically, the support platform 1 is a metal bracket structure, and the guide rod 11 is welded to the support platform 1. In addition, to prevent the support platform 1 from being pushed by water, a counterweight is provided on the support platform 1. The counterweight is, for example, a stone, a metal block, a sandbag, etc. By adding weight to the support platform 1, the guide rod 11 is ensured to be in a stable position, thereby providing a stable vertical guiding effect for the vacuum tank 2.

[0037] Specifically, the buoyancy carrier 3 is a buoyancy box or a foam body. The buoyancy carrier 3 is connected to the vacuum tank 2 by bonding or binding to avoid damage to the vacuum tank 2.

[0038] It should be emphasized that the automatic floating and sinking vacuum device of the present application adds a simple structure to the existing vacuum tank to achieve the function of automatic floating and sinking. The modification cost is low, but it can avoid unnecessary efficiency loss and is highly practical.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
