Description

Technical Field

[0001] The utility model relates to the field of pile foundation engineering, in particular to an underwater pile guide pipe positioning and pipe opening protection device. Background Art

[0002] When the underwater concrete pouring process is used for the pile foundation of foundation and foundation pit engineering, the distance (suspended height) from the bottom of the conduit to the bottom of the bored pile hole must be kept within the range required by the design and specifications. If it is too large, it will easily cause defects in the pile bottom and pile foundation settlement, and if it is too small, it will easily cause pipe blockage. The distance is controlled by measuring with a measuring rope and manual calculation.

[0003] For longer pile foundations, manual calculation of the conduit length often results in measurement errors, calculation errors, cumulative deviations and other problems. The suspended height of the conduit cannot be accurately controlled, and the conduit mouth is easily mixed with dirt, silt and other debris during installation, causing blockage. If the cleaning is not thorough enough, problems such as mud stuck in the pile core and broken piles will occur. Utility Model Content

[0004] In view of the above-mentioned problems, an underwater pile conduit positioning and pipe mouth protection device is provided. By installing a positioning and protection device for the lower mouth of the cast-in-place pile conduit, the suspended height of the conduit can be controlled and the pipe mouth is clean and unblocked.

[0005] The technical solution of this utility model is as follows:

[0006] The invention discloses an underwater pile conduit positioning and pipe opening protection device, comprising an end ring and a plurality of round steel supports, wherein the bottom ends of the round steel supports are vertically welded to the rings, and the top ends of the round steel supports are welded to the bottom of the conduit.

[0007] The round steel support is set to have a length of 30 to 50 cm and a diameter of 20 mm.

[0008] The four round steel supports are evenly distributed on the circular ring.

[0009] The diameter of the end ring is 20 mm.

[0010] Technical effects and advantages of the utility model:

[0011] 1. It can effectively prevent the conduit mouth from contacting soil and silt during transportation and installation, keeping the pipe mouth clean and free of mud.

[0012] 2. Compared with the traditional method of controlling the suspended height of the conduit, this patent reduces installation errors caused by operators' manual measurement and calculation errors, improves production efficiency, ensures the quality of pile bottom construction, and reduces defects such as mud stuck in the pile body.

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1

[0019] like Figure 1 and Figure 2 The underwater pile conduit positioning and pipe opening protection device shown includes an end ring 1 and four round steel supports 2. The bottom ends of the round steel supports 2 are vertically welded to the ring 1, and the top ends of the round steel supports 2 are welded to the bottom of the conduit 3.

[0020] Furthermore, the round steel support is set to have a length of 30 to 50 cm and a diameter of 20 mm.

[0021] Furthermore, the diameter of the end ring is 20 mm.

[0022] Furthermore, an orifice bracket 4 is provided, wherein the orifice bracket 4 is installed on the ground through sleepers, and the conduit passes through the orifice bracket, and the orifice bracket is used to support the conduit to prevent excessive tilting.

[0023] Furthermore, the length of the supporting steel bar at the bottom of the conduit is determined according to the pile diameter, the geological conditions at the bottom of the hole, and the concrete workability factors. According to the specification requirements, a round steel support with a length of 30 to 50 cm is set, which can save the cumbersome manual measurement and calculation process. The hanging height can also be calculated according to the traditional method, and this device is used as a means of verification and inspection.

[0024] Implementation column 2

[0025] like Figure 3 and Figure 4 As shown, the construction steps are:

[0026] 1. After the pile foundation is drilled and inspected, the bottom of the conduit and the supporting steel bars are welded in advance to form a positioning and protective device.

[0027] 2. Continue to extend the conduit until the support device at the bottom of the conduit falls to the bottom of the hole and the suspended height of the bottom of the conduit is fixed.

[0028] 3. Pour underwater concrete in the normal way and control the buried depth of the conduit to 2-4m below the concrete surface to prevent difficulty in removing the conduit due to excessive burial depth.

[0029] 4. After the underwater pile concrete pouring is completed, gradually remove the guide tubes and rinse them clean, then organize and stack them neatly for next use.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
