Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a quick cleaning device for prestressed pipe pile heads in a basement. Background Art

[0002] Building construction may involve basement construction. During basement construction, prestressed pipe piles are generally used to improve the bearing capacity. The connection between prestressed hollow pipe piles and the foundation mostly adopts the method of in-hole core pouring. That is, after the debris in the pile core is cleaned, a prefabricated steel cage is placed and micro-expansive concrete is poured. The steel cage is used to form an effective and reliable connection with the subsequently poured foundation concrete.

[0003] Before using prestressed pipe piles, debris in the pile core needs to be cleared. The existing technology generally adopts manual hole cleaning or mechanical hole cleaning. The existing mechanical hole cleaning generally adopts a rotary drilling rig or an air compressor.

[0004] The principle of using an air compressor to clean the pile core is to send compressed air into the core of the pipe pile. Due to the high internal air pressure, the compressed air rises along the pile wall, thereby blowing the debris in the hole out of the pile mouth. If the soil is highly fluid sand or silt, using an air compressor will cause sand and gravel to splash, and sand and soil will remain on the pile wall, resulting in poor cleaning ability. Utility Model Content

[0005] In order to solve the problem in the background technology that if the soil in the hole core to be cleaned is sand or silt with high fluidity, the cleaning effect produced by using an air compressor is poor, the utility model proposes a quick cleaning device for the pile head of a basement prestressed pipe pile.

[0035] The connecting frame 5 is provided with a plurality of connecting grooves, and the upper ends of the round tubes 4 are fixedly inserted into the connecting grooves.

[0036] A height adjustment member 6 is provided on the support plate 2, and the height adjustment member 6 includes a support screw 601, which is fixedly connected to the upper surface of the support plate 2. An adjustment frame 602 is provided on the support screw 601, and an upper and lower transparent avoidance opening is opened on the adjustment frame 602. The adjustment frame 602 is movably mounted on the support screw 601 through the avoidance opening, and the outer surface of the adjustment frame 602 is fixedly connected to the outer surface of the connecting frame 5.

[0037] A second support plate 603 is provided on the support screw 601, and the second support plate 603 extends in the left and right directions. A connecting hole that is transparent from top to bottom is opened in the second support plate 603, and a threaded structure that is adapted to the support screw 601 is provided in the connecting hole. The second support plate 603 is threadedly sleeved on the support screw 601 through the connecting hole, and the upper surface of the second support plate 603 contacts the lower surface of the adjustment frame 602.

[0038] Working principle: Before construction, the workers first bury the prestressed pipe piles using a pile driver, and then clean the pile cores of the prestressed pipe piles.

[0039] First, insert the installation rod 1 into the soil around the prestressed pipe pile so that the ground nail 101 is inserted into the soil. Then the construction personnel rotate the first connecting plate 103 so that the first connecting plate 103 moves up and down on the screw rod 102, thereby adjusting the position of the first connecting plate 103 on the screw rod 102. After adjusting the first connecting plates 103 on the four installation rods 1 to the appropriate height, the construction personnel place the support plate 2 on the installation structure composed of the four installation rods 1, so that the installation rod 1 is inserted into the socket on the support plate 2, so that the lower surface of the support plate 2 is in contact with the upper surface of the first connecting plate 103.

[0040] The construction workers connected the external water supply system to one of the circular pipes 4 through the connecting water pipe 7, and the remaining circular pipes 4 were connected to the air compressor 8.

[0041] The construction personnel can rotate the second support plate 603 to move the second support plate 603 up and down on the screw rod 102. After moving the second support plate 603, the construction personnel can move the adjustment frame 602. The adjustment frame 602 moves up and down to drive the connecting frame 5 to move up and down.

[0042] When it is necessary to insert the circular tube 4 into the core of the prestressed pipe pile, the construction personnel apply a downward thrust to the connecting frame 5, and the connecting frame 5 moves downward under the force. The downward movement of the connecting frame 5 drives the circular tube 4 to move, and the circular tube 4 is inserted downward into the soil until the lower surface of the adjusting frame 602 contacts the upper surface of the second support plate 603. In this way, the downward displacement distance of the circular tube 4 can be limited, so that the depth of the circular tube 4 inserted into the soil is more accurate, and thus the hole cleaning depth is more accurate.

[0043] After the circular tube 4 is inserted into the soil, the construction workers start the water supply system, which sends water into the circular tube 4 through the connecting water pipe 7, and the circular tube 4 sends water into the pile core, so that the sand and silt in the pile core are soaked. Since the sand has good water permeability, it can quickly absorb water and bond the soil. Then the construction workers use the air compressor 8 to supply air to the circular tube 4, and the circular tube 4 sends air into the lower part of the pile core. The internal air pressure becomes greater, causing the compressed air to rise along the pile wall, and finally blow the sand out of the prestressed pipe pile, and finally the water and sand are cleaned together.

[0044] In this way, water can be used to make the sand and soil stick together first, and then an air compressor can be used for mechanical cleaning, thereby achieving a better cleaning effect on the pile core debris in sand and silt soil. At the same time, the device has a simple structure and is easy to disassemble and assemble quickly. It can be quickly assembled before construction and quickly disassembled and assembled after completion, adapting to different construction sites.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
