Detailed Description
The following detailed description is exemplary and is intended to provide further explanation of the utility model as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
As described in the background art, during foundation pit supporting, the U-shaped steel sheet piles can well complete the work of water sealing and soil retaining, but the locking structures at the joints of adjacent steel sheet piles are difficult to obtain a good sealing effect, so that the cofferdam formed by a plurality of groups of U-shaped steel sheet piles has a poor waterproof effect.
The first embodiment is as follows:
as shown in fig. 1-3, a U-shaped steel sheet pile with a vortex-structure lock catch comprises a rib plate 1 and wing plates 2 connected to two sides, wherein one end of each wing plate 2, which is far away from the rib plate 1, is provided with a vortex-structure lock catch.
The wing plates 2 on the two sides and the vertical bisector of the ribbed plate 1 are symmetrically distributed, and the included angle between the wing plates 2 on the two sides and the ribbed plate 1 is 120 degrees.
The lock catch is a vortex structure which is matched with a pair of structures and rotates clockwise or anticlockwise.
The lock catch comprises a first lock catch 3 and a second lock catch 4, taking fig. 1 as an example, when the opening direction of the cross section of the U-shaped steel sheet pile is upward, the first lock catch 3 is located on the left side of the vertical bisector of the U-shaped steel sheet pile, and the second lock catch 4 is located on the right side.
As shown in fig. 2, when the first lock catch 3 is in a vortex structure rotating clockwise, the second lock catch 4 is also in a vortex structure rotating clockwise, and the second lock catch 4 and the first lock catch 3 are matched in size and shape and are tightly combined together after installation.
The vortex structures of the first lock catch 3 and the second lock catch 4 are clockwise or counterclockwise in the same rotation direction, and fig. 2 takes a clockwise direction as an example, and a counterclockwise rotation vortex direction can also be adopted.
The vortex structure end point of the second lock catch 4 is provided with a water stop strip 5, and the length of the water stop strip 5 is consistent with that of the U-shaped steel sheet pile.
As shown in fig. 2-3, when the multiple groups of U-shaped steel sheet piles are connected by the vortex structures at both sides to form the cofferdam, the opening directions of two adjacent groups of U-shaped steel sheet piles are the same, and the second lock catch 4 at one side of one group of U-shaped steel sheet piles is matched with the first lock catch 3 at the other side of the adjacent U-shaped steel sheet piles for locking.
When two adjacent sets of U shaped steel sheet piles utilize first hasp 3 and second hasp 4 to constitute vortex structure's hasp completion to connect, the opening direction of U type is towards one side, can be according to excavation supporting's actual demand, and the opening setting is in the cofferdam inboard or the cofferdam outside, is different from two adjacent sets of Larsen shaped steel sheet piles at present and is the connected mode that opening direction is opposite to make every a set of U shaped steel sheet pile atress even.
The vortex type lock catch is bent at one end of the wing plate 2 and is integrated with the wing plate 2, so that the manufacturing cost is greatly saved, and the manufacturing difficulty is reduced.
The vortex structure direction of rotation of first hasp 3 and second hasp 4 is the same, forms vortex hasp back, closely combines together after adjacent two sets of U shaped steel sheet pile installation, and U type opening orientation is with one side, effectively prevents rivers and passes through, and the sealing strip 5 is extruded by both in the inside space of hasp structure simultaneously, fills the inside space of hasp structure completely, further improves the leakproofness to water.
Meanwhile, the water stop strip 5 has elasticity and resilience, a water expansion type rubber water stop strip with the volume expansion rate of 300% in static distilled water is selected, once the water stop strip 5 is in contact with water immersed in the lock catch, the volume of the water stop strip rapidly expands, the lock catch is extruded to be compact, and finally complete water stop is achieved.
U type steel sheet pile overall structure is bent by the steel sheet and is made, and the vortex hasp thickness of floor, pterygoid lamina and both sides pterygoid lamina tip that obtains through the clod wash is all the same, and the leakproofness is good after the interlocking, and the vortex hasp cooperation meets water inflation rubber waterstop, plays the effect of dual stagnant water, effectively prevents rivers infiltration. The U-shaped structure of the Larsen steel sheet pile is continuously used for the steel sheet pile, and the reasonable sectional area improves the supporting effect on the foundation pit.
The specific operation steps during installation are as follows:
and positioning and paying off at the position of the foundation pit to be supported. Before inserting and driving, the underground construction condition must be familiar, and the central line of the support pile must be accurately discharged.
Further, a pile driver is used for clamping the U-shaped steel sheet pile locked by the vortex structure, and the steel sheet pile is vertically inserted into the ground. As shown in fig. 2, the opening directions of the steel sheet piles combined in pairs are the same, the second lock catch 4 of the front group of steel sheet piles and the first lock catch 3 of the rear group of steel sheet piles are tightly combined, and the water-swelling rubber water stop has good water-proofing capacity by matching with the expansibility of the water-swelling rubber water stop.
Furthermore, in the process of inserting and driving the steel sheet piles, the construction condition of the steel sheet piles needs to be measured at any time, the inclination of the steel sheet piles cannot exceed 2%, and if the inclination is large, the steel sheet piles need to be pulled out and inserted and driven again. In the inserting and driving process, the vortex-type locks of the two steel sheet piles must be accurately butted and cannot be damaged, otherwise, the waterproofness of the steel sheet piles and the reutilization of the steel sheet piles are influenced.
After the construction inside the foundation pit is completed and earthwork is backfilled, the steel sheet piles are sequentially pulled out from one side by using a pile driver, the pile pulling sequence is preferably opposite to the pile driving sequence, and the perpendicularity of the steel sheet piles is still ensured in the pulling process so as to avoid collision and deformation of the steel sheet piles. After the vortex structure is pulled out, the lock of the vortex structure needs to be checked and maintained, and the water-swelling rubber water stop strip needs to be taken out and replaced.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts by those skilled in the art based on the technical solution of the present invention.
