Description

Technical Field

[0001] The utility model relates to the technical field of support structures for deep foundation pit engineering, in particular to a support structure for deep foundation pit engineering that is convenient for drainage. Background Technique

[0002] Deep foundation pit engineering often includes the design and construction of the foundation pit support system and earth excavation. It is a very comprehensive systematic project. Support structures are often required in deep foundation pit engineering. It is a temporary structure and is no longer needed after the completion of underground engineering construction. However, there are still some defects in the specific use of the support structure for deep foundation pit engineering.

[0003] The support structure for deep foundation pit engineering often can only achieve a single support and protection for the inside of the deep foundation pit. It generally does not have a drainage structure, which is not conducive to excessive water accumulation on the inner wall of the supported deep foundation pit due to rainfall, etc., and then leads to instability or damage of the support structure due to water immersion. Moreover, it often only has a metal support skeleton with a fixed specification, does not have an elastic buffer protection structure and is not easy to flexibly adjust the size of the support area, which results in low applicability of the device. Based on this, we propose a new type of support structure for deep foundation pit engineering that is convenient for drainage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a support structure for deep foundation pit engineering that is convenient for drainage, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A support structure for deep foundation pit engineering that is convenient for drainage, including a drainage main pipe and a second support column. One end of the second support column is evenly welded with a horizontally telescopic support column. The output end of the horizontally telescopic support column is slidably connected with an output rod. The horizontally telescopic support column is evenly threaded with a locking knob that matches the output rod. The output rod is welded with a first support column. The drainage main pipe is arranged on the top of the first support column. A water pump is installed on the drainage main pipe. Both sides of the bottom of the drainage main pipe are welded with drainage branch pipes. The bottoms of the first support column and the second support column are evenly welded with first fixed anchor bolts. One end of the first support column and the second support column are both installed with buffer side explosion-proof airbags. The edge of the buffer side explosion-proof airbag is bonded with a silicone rubber reinforcement frame. The top of the buffer side explosion-proof airbag is provided with a gas guiding component. A gas valve is installed on the gas guiding component. Both sides of the buffer side explosion-proof airbag are evenly connected with second fixed anchor bolts.

[0006] Preferably, a flange is arranged at the top of the drainage main pipe, so that it is convenient for the drainage main pipe to be externally connected to corresponding water collection equipment.

[0007] Preferably, an anti-slip rubber block matching the output rod is bonded to the bottom of the locking knob, making it convenient to rotate the locking knob to press or loosen the output rod at the bottom.

[0008] Preferably, a filter cylinder is threadedly connected to the bottom of the drain branch pipe, and a metal filter screen layer is arranged inside the filter cylinder, so that the drain branch pipe achieves better filtering and anti-blocking protection.

[0009] Preferably, a nano-ceramic wear-resistant coating is coated on the outer wall of the side explosion-proof airbag for buffering, improving the wear-resistant and anti-adhesion effect of the outer wall of the side explosion-proof airbag for buffering.

[0010] Preferably, one end of the side explosion-proof airbag for buffering is fixed with an installation seat, and screws are evenly arranged on the installation seat. Both the first support column and the second support column are snap-connected with the installation seat, making it convenient to disassemble, install and maintain the side explosion-proof airbag for buffering on the first support column and the second support column.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) By installing drain branch pipes and the like, the deep foundation pit engineering support structure facilitating drainage optimizes its own performance. The user can start the water pump installed on the drain main pipe, and through the drain main pipe and the drain branch pipes welded to both sides of its bottom and extending into the deep foundation pit, automatically drain the water accumulated inside the deep foundation pit due to rainfall and the like, which enables the device to achieve a better drainage function and enhance its practicability;

[0015] (2) By installing horizontally telescopic support columns and the like, the deep foundation pit engineering support structure facilitating drainage optimizes its own structure. The user can, based on the support requirements of the deep foundation pit, loosen the locking knob, pull out the output rod slidably connected inside the horizontally telescopic support column, and change the distance between the first support column and the second support column, thereby facilitating the user to flexibly adjust the area size of the support framework composed of the first support column, the second support column, the horizontally telescopic support column and the output rod, and thus enhancing the applicability of the device;

[0016] (3) By installing the first support column and other components, when the support structure for the deep foundation pit facilitating drainage is actually used, after fixing the support framework composed of the first support column, the second support column, the horizontally telescopic support column, and the output rod inside the deep foundation pit, the user can open the air valve on the side explosion-proof airbag for buffering installed on the side ends of the first support column and the second support column, which facilitates the user to inflate the side explosion-proof airbag for buffering through the air duct component by using an electric air pump, making the side explosion-proof airbag for buffering expand and press against the inner wall of the deep foundation pit. This enables the device to achieve better support and buffering protection for the inner wall of the deep foundation pit, avoids damage to the support framework under pressure, and extends the service life of the device.
