Constructors are reminded to close the grouting machine in time, and the surface of the bottom plate is prevented from floating upwards continuously.

Description

Technical Field

[0001] The utility model relates to the technical field of curtain grouting, and particularly relates to a pressure controller capable of preventing the floating of a bottom plate curtain grouting structure. Background Technique

[0002] In construction, the bottom plate curtain grouting structure is a common construction method. Bottom plate curtain grouting is a commonly used foundation treatment method in construction, especially in underground structures such as basements, tunnels, subway stations, etc. The main purposes of this method are to enhance the bearing capacity of the foundation, reduce foundation settlement, improve waterproof performance, and prevent groundwater seepage. However, during the grouting process, due to uneven or excessive grouting pressure, the bottom plate surface often floats, thus affecting the construction quality and project safety. At present, there is a lack of an effective device in the market to monitor and control the floating of the bottom plate surface during the grouting process in real time. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pressure controller capable of preventing the floating of a bottom plate curtain grouting structure to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A pressure controller capable of preventing the floating of a bottom plate curtain grouting structure, including a building main body, a grouting layer, a bottom plate, a top plate, a grouting pipe, a valve, a laser distance measuring controller, and an alarm. A grouting layer is arranged inside the building main body, a bottom plate is arranged at the top of the building main body, the bottom plate is located above the grouting layer, a top plate is arranged above the bottom plate, the grouting pipe penetrates through the bottom plate, and the bottom end of the grouting pipe extends into the grouting layer. The valve is arranged on the grouting pipe. A laser distance measuring controller is arranged on the top of the bottom plate, the top end of the laser distance measuring controller is in contact with the top plate, and an alarm is also arranged on the top of the bottom plate. The laser distance measuring controller is electrically connected to the alarm and the valve respectively.

[0005] Compared with the prior art, the beneficial effect of the utility model is that: The laser distance measurer arranged between the top plate and the bottom plate of the utility model can monitor the distance between the bottom plate and the top plate in real time, realize the real-time monitoring of the floating of the bottom plate surface during the grouting process. When the floating of the bottom plate surface exceeds the preset threshold, the laser distance measuring controller triggers the alarm to timely remind the construction personnel to turn off the grouting machinery and prevent the bottom plate surface from continuing to float.

[0008] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0009] Please refer to Figure 1 , the present invention provides a pressure controller that can prevent the floating of the bottom plate curtain grouting structure, including a building main body 1, a grouting layer 2, a bottom plate 3, a top plate 4, a grouting pipe 5, a valve 6, a laser distance measurement controller 7, and an alarm 8. A grouting layer 2 is arranged inside the building main body 1. A bottom plate 3 is arranged at the top of the building main body 1. The bottom plate 3 is located above the grouting layer 2. A top plate 4 is arranged above the bottom plate 3. The grouting pipe 5 penetrates through the bottom plate 3, and the bottom end of the grouting pipe 5 extends into the grouting layer 2. The valve 6 is arranged on the grouting pipe 5. A laser distance measurement controller 7 is arranged on the top of the bottom plate 3. The top end of the laser distance measurement controller 7 is in contact with the top plate 4. An alarm 8 is also arranged on the top of the bottom plate 3. The laser distance measurement controller 7 is electrically connected to the alarm 8 and the valve 6 respectively.

[0010] Working principle: During the grouting process, first, the staff drills holes in the building main body 1 and the bottom plate 3 until reaching the grouting layer 2. After the drilling is completed, the grouting pipe is inserted into the hole, and its bottom end extends into the grouting layer. Then, the laser distance measurement controller 7 is installed on the bottom plate 3, and its top end is connected to the top plate 4. Then, grouting can be carried out. When the bottom plate 3 floats during the grouting process, the laser distance measurer detects a change in the distance between the bottom plate 3 and the top plate 4. When the distance change exceeds a preset threshold (such as 3 mm), the laser distance measurement controller 7 triggers the alarm 8 and closes the valve 6 of the grouting pipe to ensure that the grouting process is carried out under appropriate pressure.

[0011] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
