Description

TECHNICAL FIELD

[0001] The present application relates to the field of water source pressurized pump station foundation pit support, and particularly relates to a water source pressurized pump station foundation pit support structure. BACKGROUND

[0002] In water conservancy construction, as a key facility for ensuring stable water supply, the stability and safety of the foundation pit support of a water source pressurized pump station are crucial. At present, for the foundation pit support of a water source pressurized pump station, a steel pipe pile support technology is generally used, that is, a plurality of steel pipe piles are sunk in the pit wall of the foundation pit to form a rectangular structure to achieve preliminary support, and then a steel enclose purlin is installed inside the steel pipe pile rectangular structure, and a pull anchor is arranged for auxiliary support, so as to enhance the overall stability of the foundation pit.

[0003] However, the above-mentioned traditional support process has certain deficiencies. In the steel pipe pile sinking process, because the construction process needs to sink the piles on each side of the foundation pit in stages, when the sinking of the steel pipe piles on one side of the foundation pit is completed, the sinking of the steel pipe piles on the other side is carried out, and the sunk steel pipe piles are in a state without targeted protection. The land vibration generated in the sinking operation can disturb the surrounding soil, and this disturbance can cause the sunk steel pipe piles to slightly deviate or tilt, thereby damaging the overall perpendicularity of the steel pipe piles. Once the perpendicularity of the steel pipe piles cannot be guaranteed, not only the single pile bearing capacity will be reduced, but also the overall stability of the foundation pit support structure will be weakened, which seriously affects the construction quality of the subsequent pump station.

[0036] When supporting the foundation pit, the staff accurately measures and determines the position of the angle pile 1 at the four corners of the foundation pit, uses professional pile sinking equipment (such as a pile driver) to bury the four angle piles 1 at the four corners of the foundation pit respectively, ensures that the perpendicularity and the depth of the angle pile 1 meet the design standard, and then installs the diagonal support plate 32 and the bottom support plate 31 on the angle pile 1 respectively, at this time, the anchor rod 33 at the bottom of the bottom support plate 31 is inserted into the foundation pit, and the cooperation of the diagonal support plate 32 and the bottom support plate 31 can stably fix the angle pile 1 inside the foundation pit, effectively resist the external force generated in the subsequent construction, and protect the position and perpendicularity of the angle pile 1.

[0037] After the four angle piles 1 and the diagonal bracing member 3 are installed and stable, the staff installs four steel enclosing purlins 4 on the four diagonal support plates 32, and then sinks a plurality of steel pipe piles 2 at a designed interval between the four angle piles 1 in sequence, so that the plurality of steel pipe piles 2 and the four angle piles 1 jointly form a rectangular structure, and the preliminary support of the foundation pit is completed, at this time, the lock plate one 14 and the lock plate two 15 can realize the quick and accurate insertion between the steel pipe pile 2 and the angle pile 1 and between the steel pipe pile 2 and the steel pipe pile 2, and then the cooperation of the steel enclosing purlin 4 can effectively limit the displacement of the steel pipe pile 2 and effectively support the steel pipe pile 2, thereby enhancing the connection stability of the whole.

[0039] Referring to Figure 1 , Figure 2 and Figure 3The stable mechanism one 5 is arranged on the front and rear steel enclosing purlin 4, and the stable mechanism one 5 comprises a bottom plate one 51 arranged between the corresponding two inclined support plates 32 and a support plate 52, and the bottom plate one 51 and the support plate 52 are provided with a reinforcing piece one 53 for reinforcing the corresponding steel pipe pile 2 in cooperation with the steel enclosing purlin 4, the bottom plate one 51 is connected with the bottom support plate 31 through a plurality of bolts two, and the support plate 52 is located at the upper part of the bottom plate one 51, and the inclined support plate 32 is provided with a mounting plate 13 on the side close to the support plate 52 through a plurality of bolts three, and the side of the mounting plate 13 away from the inclined support plate 32 is connected with the support plate 52.

[0040] Referring to Figure 4 The reinforcing piece one 53 comprises a moving plate one 531 arranged outside the corresponding moving ring 8, the moving plate one 531 is fixedly provided with an inclined plate 532 on the side away from the moving ring 8, the inner side of the inclined plate 532 is fixedly provided with a plug rod one 533, the support plate 52 is provided with a plurality of round openings one through which the plug rod one 533 passes, and the bottom end of the plug rod one 533 passes through the support plate 52 and is inserted into the foundation pit, and the side of the inclined plate 532 close to the bottom plate one 51 is fixedly provided with an extrusion plate 534.

[0041] Referring to Figure 6 and Figure 7 The upper part of the steel enclosing purlin 4 is provided with a plurality of rectangular openings 10 in communication with the arc-shaped openings 7, the moving plate one 531 is located in the corresponding rectangular opening 10, the upper part of the bottom plate one 51 is provided with a groove 11 for cooperating with the extrusion plate 534, and the extrusion plate 534 is located in the corresponding groove 11. The inside of the rectangular opening 10 and the inside of the groove 11 are fixedly provided with a U-shaped clamping piece 12, the two sides of the open end of the U-shaped clamping piece 12 are provided with outwardly expanded guide sections, the transition between the U-shaped clamping piece 12 and the outwardly expanded guide sections forms an inner buckling anti-disengagement section, and the moving plate one 531 and the extrusion plate 534 are located on the inner buckling anti-disengagement section of the corresponding U-shaped clamping piece 12.

[0042] When the diagonal pile 1 is fixed, the plurality of steel pipe piles 2 on the front and rear sides are driven, the staff first installs the bottom plate one 51 and the support plate 52 between the corresponding two bottom support plates 31 and inclined support plates 32, then installs the reinforcing piece one 53 on the corresponding steel enclosing purlin 4, and aligns the moving plate one 531 and the extrusion plate 534 with the rectangular openings 10 on the steel enclosing purlin 4 and the grooves 11 on the bottom plate one 51 respectively, so that the moving plate one 531 and the extrusion plate 534 are located in the outwardly expanded guide sections of the corresponding U-shaped clamping pieces 12, at this time, the moving plate one 531 is located at the upper end of the rectangular opening 10, the extrusion plate 534 is located at the upper end of the groove 11, and the bottom end of the plug rod one 533 passes through the support plate 52 and contacts the foundation pit, thereby preliminarily completing the pre-installation of the stable mechanism one 5 on the steel enclosing purlin 4 and the inclined support piece 3, and facilitating the subsequent support of the steel pipe pile 2.

[0043] When the pile driving equipment is used to drive the plurality of steel pipe piles 2 on the front and rear sides, the extrusion ring 9 outside the steel pipe pile 2 moves downward synchronously with the steel pipe pile 2. When the extrusion ring 9 contacts the moving ring 8 in the arc-shaped opening 7 of the steel enclosing purlin 4, the extrusion ring 9 that continues to press downward generates downward extrusion force on the moving ring 8, forcing the moving ring 8 to move into the arc-shaped opening 7. When the moving ring 8 moves downward into the arc-shaped opening 7, the steel pipe pile 2 stops moving at the predetermined position. When the moving ring 8 moves downward, the moving plate one 531 moves downward synchronously. The moving plate one 531 slides downward along the rectangular opening 10, enters the inner buckle anti-extraction section through the outwardly expanding guide section of the U-shaped clamping piece 12, and the inclined plate 532 connected with the moving plate one 531 drives the extrusion plate 534 to move downward along the groove 11, which is also clamped into the inner buckle anti-extraction section of the U-shaped clamping piece 12. The inner buckle anti-extraction section of the U-shaped clamping piece 12 forms a limit on the moving plate one 531 and the extrusion plate 534 through its special inwardly retracting structure, preventing them from being extracted upward to achieve automatic locking (as shown in Figure 8 ).

[0044] During the downward movement of the moving plate one 531 and the extrusion plate 534, the inclined plate 532 drives the insertion rod one 533 to move downward synchronously. The bottom end of the insertion rod one 533 gradually inserts into the foundation pit soil. With the deepening of the insertion rod one 533, the pressure of the extrusion plate 534 on the bottom plate one 51 and the supporting effect of the supporting plate 52 tightly connect the front and rear steel pipe piles 2, the steel enclosing purlins 4, the corner piles 1 and the foundation pit soil, forming a stable overall structure. With the increase in the number of steel pipe piles 2, the overall supporting effect is stronger, thereby effectively enhancing the lateral support of the steel pipe piles 2 and improving the stability of the foundation pit support system.

[0045] Referring to Figure 1 , Figure 2 and Figure 3 , the stable mechanism two 6 is arranged on the left and right steel enclosing purlins 4. The stable mechanism two 6 includes a bottom plate two 61 arranged between the corresponding two bottom plate ones 51. The bottom plate two 61 is provided with a reinforcing piece two 62 for reinforcing the steel pipe pile 2 in cooperation with the corresponding steel enclosing purlin 4. The bottom plate two 61 and the bottom plate one 51 are connected by a plurality of bolts three.

[0046] Referring to Figure 5 , the reinforcing piece two 62 includes a moving plate two 621 arranged in the corresponding rectangular opening 10. The moving plate two 621 is located in the inner buckle anti-extraction section of the corresponding U-shaped clamping piece 12. The bottom of the moving plate two 621 is fixedly provided with an insertion rod two 622. The bottom end of the insertion rod two 622 penetrates the corresponding U-shaped clamping piece 12, the steel enclosing purlin 4 and the bottom plate two 61 in sequence and is inserted into the foundation pit. A plurality of circular openings two are formed in the bottom plate two 61 for the insertion rod two 622 to penetrate.

[0047] After the steel pipe piles 2 on the front and rear sides are driven, the steel pipe piles 2 on the left and right sides can be driven, and the staff can first install the bottom plate two 61 between the two bottom plates one 51, and then install the reinforcing member two 62 on the corresponding steel enclosing purlin 4, at this time the bottom end of the insertion rod two 622 passes through the corresponding steel enclosing purlin 4 and the bottom plate two 61 in turn and is in contact with the foundation pit, and the moving plate two 621 is located in the outwardly expanded guide section of the corresponding U-shaped clamping piece 12, and then when the steel pipe pile 2 is driven, the cooperation of the extrusion ring 9 and the moving ring 8 can make the moving plate two 621 move to the inner buckling anti-disengagement section of the corresponding U-shaped clamping piece 12, and the moving plate two 621 can drive the insertion rod two 622 to move downward and insert into the foundation pit when moving, so as to tightly connect the steel pipe piles 2, the steel enclosing purlin 4, the corner pile 1 and the foundation pit soil on the left and right sides, and since the bottom plate one 51 is also connected with the bottom plate two 61, the stable mechanism one 5 and the stable mechanism two 6 form a whole stress frame, the lateral earth pressure borne by the steel pipe pile 2 can be transmitted to the stable mechanism one 5 and the stable mechanism two 6 through the steel enclosing purlin 4, and then evenly dispersed into the foundation pit soil, further enhancing the cooperative working capacity of the whole supporting system.

[0048] When the steel enclosing purlin 4 between the four corner piles 1 is driven, in order to further ensure the overall stability, the staff can adjust the driving sequence of the steel pipe piles 2, first drive the steel pipe piles 2 at the middle positions of the front and rear sides of the foundation pit, and then drive the steel pipe piles 2 at the middle positions of the left and right sides of the foundation pit (as shown in Figure 9 ). Figure 10 Then continue to drive the steel pipe piles 2 beside the steel pipe piles 2 at the middle positions of the front and rear sides of the foundation pit, and then continue to drive the steel pipe piles 2 beside the steel pipe piles 2 at the middle positions of the left and right sides of the foundation pit (as shown in Figure 10 ). According to this sequence, all the steel pipe piles 2 are driven, and this staggered and symmetrical driving sequence can make the soil stress around the foundation pit be evenly released, avoid excessive lateral extrusion of the soil caused by unilateral concentrated driving, thereby reducing the risk of deviation of the completed steel pipe piles 2, and further ensuring the overall stability.

[0049] In specific work, when supporting the foundation pit, the four corner piles 1 are buried in the four corners of the foundation pit, then the inclined bracing members 3 are installed on the corner piles 1, then the steel enclosing purlins 4 are installed on the inclined bracing members 3, then the bottom plate one 51 and the supporting plate 52 are installed on the corresponding inclined bracing members 3, and then the bottom plate two 61 is connected with the bottom plate one 51.

[0050] When the steel pipe pile 2 is driven, the reinforcing member one 53 and the reinforcing member two 62 are installed, and then a plurality of steel pipe piles 2 are driven into the foundation pit in a staggered and symmetrical driving sequence, with the driving of the steel pipe pile 2, the extrusion of the moving ring 8 by the extrusion ring 9 can drive the moving plate one 531, the inserting rod one 533, the extrusion plate 534, the moving plate two 621 and the inserting rod two 622 to move, so that the stabilizing mechanism one 5 and the stabilizing mechanism two 6 form a whole stress frame to stabilize the steel pipe pile 2, and at the same time, the stress of the soil around the foundation pit can be uniformly released, so that the excessive lateral extrusion of the soil caused by unilateral concentrated driving is avoided, thereby reducing the risk of deviation of the completed steel pipe pile 2, and further ensuring the overall stability.
