Description

Technical Field

[0001] This utility model relates to the field of building construction equipment, specifically to a device for cleaning the top of precast pipe piles. Background Technology

[0002] In the construction process, in order to strengthen the connection between precast piles and structural base slabs, it is generally necessary to clean the holes and fill them with reinforced concrete within a certain depth range at the top of the piles. However, at present, the cleaning is mainly done by manually excavating soil or by using special cleaning machinery, which is inefficient. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a precast pipe pile top cleaning device to improve the cleaning efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A precast pipe pile top cleaning device includes an air compressor, an air outlet section, and several standard sections. The end of the air outlet section is inserted into the hole at the top of the pipe pile. The standard sections are vertically fixedly connected in sequence. The bottom end of the lowest standard section is fixedly connected to the top end of the air outlet section. The air compressor is connected to the top end of the highest standard section.

[0006] As a preferred technical solution, the air outlet section is made from a 600mm long DN25 galvanized steel pipe.

[0007] As a preferred technical solution, air outlet holes on both the front and back sides are provided every 100mm on the air outlet section.

[0008] As a preferred technical solution, the end of the air outlet section is pointed.

[0009] As a preferred technical solution, the standard section is made of 500mm long DN25 galvanized steel pipe.

[0010] As a preferred technical solution, the air outlet section is connected to the lowest standard section by threading, and the standard sections are connected to each other by threading.

[0011] As a preferred technical solution, standard sections are assembled sequentially from bottom to top until the overall length of the device exceeds the hole cleaning depth.

[0012] As a preferred technical solution, the top of the uppermost standard section is connected to the air compressor via a rubber hose.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The precast pipe pile top cleaning device of this utility model mainly consists of an air outlet section and several standard sections. When in use, the operator connects the air compressor to the top of the uppermost standard section, inserts the end of the air outlet section to the specified depth, and then uses the air pressure of the air compressor to force the soil out of the hole. The efficiency is about twice that of the traditional hole cleaning method. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0020] like Figure 1 As shown, a precast pipe pile top cleaning device includes an air compressor, an air outlet section 1, and several standard sections 2. The end 11 of the air outlet section 1 is inserted into the hole at the top of the pipe pile. The standard sections 2 are vertically fixedly connected in sequence. The bottom end of the lowest standard section 2 is fixedly connected to the top end of the air outlet section 1. The air compressor is connected to the top end of the highest standard section 2.

[0021] like Figure 2 As shown, the air outlet section 1 is made from a 600mm long DN25 galvanized steel pipe.

[0022] Air outlet section 1 is provided with air outlet holes 12 on both sides every 100mm, so that the soil can be forced out of the air outlet holes 12 by the air pressure of the air compressor. The air outlet holes 12 are provided on both sides to facilitate the discharge of soil.

[0023] The end 11 of the air outlet section 1 is pointed to facilitate insertion into the soil.

[0024] like Figure 3 As shown, standard section 2 is made of 500mm long DN25 galvanized steel pipe.

[0025] The air outlet section 1 is connected to the lowest standard section 2 by threading, and each standard section 2 is connected to each other by threading.

[0026] Standard section 2 is assembled freely according to the hole cleaning depth requirements of the drawings. Specifically, standard section 2 is assembled from bottom to top until the overall length of the device exceeds the hole cleaning depth.

[0027] The top of the standard section 2 is connected to the air compressor via a rubber hose.

[0028] This device uses the gas pressure generated by an air compressor to squeeze the soil at the top of the pile out of the pile hole. The operator connects the air compressor to the top of the uppermost standard section 2, inserts the end 11 of the air outlet section 1 to the specified depth, and adjusts the air compressor to the specified pressure to squeeze out the soil in a certain range at the top of the pile. Compared with the traditional hole cleaning method, the use of this device can greatly improve the construction efficiency.

[0029] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make non-inventive modifications to this embodiment as needed, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
