[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, a foundation pit support for engineering construction comprises two symmetrically arranged support panels 1, the inner surfaces of the two support panels 1 are symmetrically installed with fixing rods 2, a support tube 3 is equidistantly installed between the two fixing rods 2, a first mounting hole 4 is symmetrically provided at the end of the support tube 3, an adjustment component is provided inside the support tube 3, the adjustment component comprises an adjustment rod 5 arranged inside the support tube 3, limiting plates 9 are symmetrically provided on both sides of the interior of the support tube 3, the surface of the adjustment rod 5 is fitted and connected with the inner surface of the support tube 3, there is a distance between the outer surface of the limiting plate 9 and the inner wall of the support tube 3, limiting grooves 10 for the limiting plate 9 to engage are symmetrically provided on both side surfaces of the adjustment rod 5, a connecting spring 13 is fixed equidistantly between one side surface of the limiting plate 9 and the support tube 3, and connecting protrusions are equidistantly provided on the other side surface of the limiting plate 9 11. The thickness of the limiting plate 9 is less than the inner wall depth of the limiting groove 10. The cross-section of the connecting protrusion 11 is a right triangle. The inner surface of the limiting groove 10 is equidistantly provided with connecting grooves 12 for the connecting protrusion 11 to engage. A fixing block 6 is fixed to one end surface of the adjusting rod 5. Second mounting holes 8 are symmetrically provided on both sides of one end surface of the fixing block 6. The cross-section of the fixing block 6 is "T"-shaped. A limiting groove 7 is provided in the middle of one end surface of the fixing block 6. Fixing screw holes 14 are symmetrically provided on the ends of the two side surfaces of the outer side of the support tube 3. Limiting bolts 15 are screwed into the fixing screw holes 14. One end surface of the limiting bolt 15 is against the surface of the limiting plate 9, which is convenient for adjusting the use length of the support tube 3, so that the support tube 3 can perform limited support for foundation pits of different widths. The operation is convenient and quick, the applicability is improved, and the practical effect is good.

[0022] like Figure 1 and Figure 4As shown, the outer surface of the support panel 1 is provided with functional components, and the functional components include a protective net 16 arranged on the outer surface of the support panel 1, and through holes 17 are opened at equal intervals on the outer surface of the support panel 1. A drainage groove 18 is opened inside the support panel 1, and the opening of the drainage groove 18 extends to the bottom end surface of the support panel 1. One end of the through hole 17 is communicated with the interior of the drainage groove 18, and fixed bosses 19 for limiting the engagement of the protective net 16 are fixed at equal intervals on the top and bottom of the outer surface of the support panel 1. One end of the fixed boss 19 is conical, and the through hole 17 is opened at an angle, which is convenient for improving the tightness of the connection between the support panel 1 and the inner wall of the foundation pit. At the same time, the support panel 1 also realizes the function of drainage during support, so that the moisture on the inner wall of the foundation pit can be discharged underground, which can improve the protection effect of the support panel 1 on the foundation pit, and has good practicality.

[0023] The utility model provides a foundation pit support for engineering construction, and the specific working principle is as follows: when the utility model needs to support a foundation pit with a wider width, it is first necessary to tightly fit the two support panels 1 with the nickel coins of the foundation pit, and then adjust the use length of the support tube 3. The worker first turns the limit bolt 15 so that one end of the limit bolt 15 is screwed into the inside of the fixing screw hole 14. At this time, the rebound force generated by the connecting spring 13 will act on the limit plate 9, so that the limit plate 9 moves to the outside of the limit groove 10, and at the same time, the connecting protrusion 11 on the surface of the limit plate 9 will be loosely connected with the connecting card groove 12. At this time, the finger can be inserted into the inside of the limit groove 7. The worker can drive the adjusting rod 5 to move to the outside of one end of the support tube 3 through the fixing block 6, so that the surface of one end of the fixing block 6 gradually approaches the surface of one of the support panels 1, until the surface of one end of the fixing block 6 is connected with the surface of the fixing rod 2, and then the limit bolt 15 can be turned again to make the limit bolt 1 One end of 5 pushes the limit plate 9 to move inside the limit groove 10 until the connecting protrusion 11 is limited and engaged with the connecting card groove 12, and then the practical bolt is screwed into the inside of the second mounting hole 8, so that the fixing block 6 can be fixedly connected with the fixing rod 2. At this time, the adjusting rod 5 will not easily move inside the support tube 3, and the purpose of supporting foundation pits of different widths is achieved. The operation is convenient and fast, the applicability is improved, and the practical effect is better; when the two supporting panels 1 are tightly fitted with the inner wall of the foundation pit, the surface of the protective net 16 will also be tightly fitted with the inner wall of the foundation pit, and the tightness of the connection between the supporting panel 1 and the inner wall of the foundation pit is improved. At the same time, water will flow out from the inner wall of the foundation pit. At this time, the water can flow through the through hole 17 to the inside of the drainage trough 18 and be discharged into the underground, and the protective net 16 can protect the opening of the through hole 17, so that the inside of the through hole 17 is not easily blocked, which is convenient to improve the protection effect of the supporting panel 1 on the foundation pit, improve functionality, and have better practicality.
