Description

Technical Field

[0001] The utility model relates to the field of pile foundation construction, and in particular to a pile foundation heat preservation and maintenance device used in a low-temperature environment. Background Art

[0002] Winter construction lasts for nearly half a year. Due to the low temperature, the pile foundations cast and constructed during this period need to be insulated and maintained. In winter construction environments or high-altitude construction environments such as the aforementioned, insulation and maintenance of pile foundations are extremely important. The acoustic detection tube is the channel for the probe to enter the interior of the pile body when the ultrasonic detection method is performed on the bored pile. It needs to be cast in the pile foundation in advance.

[0003] Based on the above reasons, the applicant considered using the existing acoustic detection tube in the pile foundation as a channel and designed a device that can achieve thermal insulation and maintenance of the pile foundation through the channel. Utility Model Content

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0022] Example 1:

[0023] Reference Figure 1This embodiment provides a heat preservation and maintenance device for a pile foundation 10 in a low-temperature environment, including an acoustic detection tube assembly 50 and a hot water source 30.

[0024] Among them, the acoustic detection tube assembly 50 includes several groups of acoustic detection tube units 500 cast in the pile foundation 10. In this embodiment, there are three groups of acoustic detection tube units 500. The acoustic detection tube units 500 are used as channels for the probes during ultrasonic detection. In this embodiment, the acoustic detection tube units 500 are used as hot water channels to achieve thermal insulation and maintenance of the pile foundation without causing damage to the acoustic detection tube units 500 themselves.

[0025] Reference Figure 1 The acoustic detection pipe units 500 can be connected to each other through the pipe fittings 51 in series, parallel or mixed connection.

[0026] The hot water source 30 is used to produce hot water between 25°C and 30°C. The hot water source 30 is connected to the pumping device 20 through a pipe 40. The hot water source 30, the pumping device 20 and the acoustic detection pipe assembly 50 are connected to form a circulation loop through the pipe 40, so that the hot water from the hot water source 30 is pumped into the acoustic detection pipe assembly 50 to heat and insulate the pile foundation 10.

[0027] In addition, the pumping device 20 is connected to a control device for controlling the pumping device 20 to pump hot water at regular intervals to achieve regular maintenance of the pile foundation 10. Experiments have shown that the traditional pile foundation 10 cycle maintenance time is generally 7 days, which can be shortened by 3 days after maintenance by this maintenance device, greatly improving the speed of increasing the concrete strength in the pile foundation 10.

[0028] Example 2:

[0029] Considering that the interconnection of several acoustic detection pipe units 500 may cause certain interference to the detection during the ultrasonic detection of the pile foundation 10, in this embodiment, the bottoms of the several acoustic detection pipe units 500 are interconnected through pipes 51.

[0030] Reference Figure 2 In this embodiment, the pipe fitting 51 is provided with pipe joints 511 equal in number to the acoustic detection tube units 500 in the acoustic detection tube assembly 50. Each set of pipe joints 511 has a first end and a second end opposite each other, and the first end of the pipe joint 511 is higher than the second end, that is, the pipe joints 511 are arranged at an angle. The first end of each set of pipe joints 511 is connected to a set of acoustic detection tube units 500 by a threaded connection, and the second ends of the plurality of acoustic detection tube units 500 are connected to each other and are all connected to a set of center columns 512.

[0031] After the thermal insulation and maintenance device is used, grouting material can be injected into the pipe fitting 51 through the ultrasonic detection pipe unit 500. Since the second end of the pipe joint 511 is lower than the first end, during the process of pouring the grouting material, the grouting material can first fill the middle column 512 and the second end of the pipe joint 511, and finally fill the pipe fitting 51, reducing the impact on the ultrasonic detection pipe unit 500 during ultrasonic detection.

[0032] In some embodiments, a group of bases 510 are further included, and the pipe fittings 51 are installed on the bases 510 to facilitate the support and fixation of the pipe fittings 51 during the casting process.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
