Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction, in particular to a dewatering support construction device for a deep foundation pit of a building. Background Art
[0002] The excavation of foundation pits is a high-risk construction project. In foundation pit excavation under water-rich geological conditions, due to the serious lack of soil bearing capacity and high water level, if safe and effective support and dewatering measures are not taken, it is very easy to cause collapse and burial accidents, affecting the safety of workers and the progress of the project. Dewatering in foundation pit support refers to the dewatering work done when the groundwater level is higher than the excavation bottom surface during foundation pit excavation. Groundwater will continue to seep into the pit to ensure that the foundation pit can be constructed under dry conditions, prevent slope instability, foundation sand flow, pit bottom uplift, pit bottom pipe burst and reduced foundation bearing capacity.
[0003] Therefore, during the construction of the foundation pit, corresponding support construction devices will be used to assist in the support to prevent the risk of collapse of the foundation pit. However, some support devices in the existing technology will install the base and the support plate with conventional bearings for the convenience of support. In this way, the support plate can be rotated to make the support plate and the base vertical to support the pit surface. However, since the foundation pit will seep water, it is easy for the bearings at the connection to rust and get stuck, making it difficult to rotate and causing a jam. Summary of the Invention

[0016] By setting two oil grooves on both sides of the ring groove, filling the oil grooves with lubricating oil and absorbing it with oil-absorbing cotton, the ball contacts the oil-absorbing cotton during rotation so that it can be applied to the ball, increasing lubricity and preventing rust and difficulty in rotation. If used in conjunction with the sleeve, it can rotate very well.
[0017] The two supporting bodies are connected together through two connecting parts, and the connecting plate is inserted into the connecting groove. When the pressing plate is pressed using the pressure of the wall, the pressing rod set at the bottom of the pressing plate will cooperate with the inclined groove of the connecting plate. In this way, the inclined groove can be used to press the connecting plate to keep it close to the innermost part of the connecting groove, making it tighter to prevent separation.
[0018] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.
[0019] Undoubtedly, these and other objects of the present invention will become more apparent after the following detailed description of the preferred embodiment is described with reference to the various figures and drawings.
