The utility model discloses a circular arc steel sheet realizes that the steel pipe is connected with the PRC tubular pile, has formed effectual support system between two PRC tubular piles, and it is high to have solved tubular pile concrete intensity, and the curved surface supports the difficult problem that is difficult to fix.
Description
Technical Field
The utility model relates to a deep basal pit supporting construction system especially relates to a PRC tubular pile supporting construction's deep basal pit steel pipe strutting arrangement.
Background
when municipal water conservancy box culvert foundation ditch steel pipe supports were installed, because foundation ditch supporting construction PRC (prestressed reinforced concrete) tubular pile intensity is high, and the surface is the arc surface, influenced this steel pipe support and can't be connected with the tubular pile, formed effective support system. In the prior art, the bracket is required to be connected with the tubular pile, and the rear support tubular pile is in lap joint with the bracket, so that the problems of long operation time, high labor intensity, low adaptability and the like are caused.
SUMMERY OF THE UTILITY MODEL

Detailed Description
The invention is described in further detail below with reference to the drawings and specific examples.
As shown in fig. 1, the deep foundation pit steel pipe supporting device of the PRC tubular pile supporting structure of this embodiment includes a steel pipe 1 and arc steel plates 2 respectively disposed at two ends of the steel pipe 1, each end of the steel pipe 1 is fixedly connected to the convex surfaces of the two arc steel plates 2, and each arc steel plate 2 is fixedly connected to a PRC tubular pile 3 through a fastening member. During the use, laminate the concave surface of an circular arc steel sheet 2 on the outer wall of a PRC tubular pile 3, fix circular arc steel sheet 2 and PRC tubular pile 3 through the fastener, then laminate the concave surface of another circular arc steel sheet 2 on the outer wall of a PRC tubular pile 3, fix circular arc steel sheet 2 and PRC tubular pile 3 through the fastener, realized that steel pipe 1 is connected with two PRC tubular piles 3, formed effectual support system between two PRC tubular piles 3, as shown in FIG. 2.
In this embodiment, specifically, the steel pipe 1 and the convex surface of the arc steel plate 2 are connected by welding. Besides this embodiment, other connection methods, such as the connection between the steel pipe 1 and the arc steel plate 2, can be used under the condition of ensuring the connection strength between the steel pipe 1 and the arc steel plate 2
As shown in fig. 3, a specific fastener in this embodiment is an expansion bolt 4. Expansion bolts 4 are equipped with four, and two bisymmetry branches are located the both ends of circular arc steel sheet 2, realize through expansion bolts 4 that circular arc steel sheet 2 and PRC tubular pile 3's are fixed, have safe and reliable, dismantle convenient advantage, and two circular arc steel sheets 2 all are connected with PRC tubular pile 3 through four expansion bolts 4.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention. The technical solution of the present invention can be used by anyone skilled in the art to make many possible variations and modifications, or to modify equivalent embodiments, without departing from the scope of the technical solution of the present invention, using the technical content disclosed above. Therefore, any simple modification, equivalent change and modification made to the above embodiments by the technical entity of the present invention should fall within the protection scope of the technical solution of the present invention.
