[0048] In the related art, the maintenance method of the existing bent cap usually adopts artificial water pipe spraying and drip irrigation maintenance by placing a water storage bucket on the bent cap. The former method is prone to problems such as untimely maintenance and insufficient maintenance time, and the latter method is also prone to problems such as insufficient maintenance time (not timely water filling) and uneven maintenance. In order to ensure the maintenance effect, a large amount of manpower and material resources need to be spent in the previous method, and it is possible to achieve the effect. The existing conventional maintenance method cannot meet the requirements of bent cap maintenance construction, especially for bent caps with high height and large volume. Therefore, the technical scheme of the present application is generated. The following will be described in combination with Figures 1 to 5 .

[0049] Embodiment 1

[0050] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the concrete bent cap maintenance construction method of the present application comprises the following steps:

[0051] Step one, according to the length of the bent cap 01, cut and make a maintenance main pipe 4, the maintenance main pipe 4 comprises a plurality of segments, the standard segment is 2m long, and if the remaining position is less than 2m, a non-standard segment is made alone.

[0052] The length of the transverse maintenance branch pipe 6 is cut and made according to the width of the bent cap 01, and the end of the transverse maintenance branch pipe 6 is required to be installed with a first spray head 61, and the whole can be 2cm wider than the bent cap 01, the spacing of the transverse maintenance branch pipe 6 is 2m, and finally a transverse maintenance branch pipe 6 is arranged at the position of the end part less than 2m; a first switch 62 capable of adjusting the water quantity is arranged on the transverse maintenance branch pipe 6.

[0053] The spacing of the vertical maintenance branch pipe 5 is set to 0.5m, the second spray head 51 is installed at the top of the vertical maintenance branch pipe 5, the second spray head 51 adopts a 360-degree ring spray head, and the height of the vertical maintenance branch pipe 5 is about 0.1m; a second switch 52 capable of adjusting the water quantity is installed on the vertical maintenance branch pipe 5.

[0054] After the making of the maintenance main pipe 4, the transverse maintenance branch pipe 6 and the vertical maintenance branch pipe 5 are completed, corresponding four-way pipes and spray heads are prepared for standby. The diameter of the maintenance main pipe 4 is 4cm-6cm, the diameter of the transverse maintenance branch pipe 6 is 2cm, and the diameter of the vertical maintenance branch pipe 5 is 2cm. The maintenance main pipe 4, the transverse maintenance branch pipe 6 and the vertical maintenance branch pipe 5 can all adopt PE pipes.

[0055] Step two, connect the maintenance main pipe 4 with four-way pipe joints in sequence and place it on the longitudinal axis of the top surface of the bent cap 01, and the end of the maintenance main pipe 4 is blocked stably.

[0056] The transverse maintenance branch pipe 6 is installed on the left and right sides of the four-way pipe joint, and the first spray head 61 is installed at the end of the transverse maintenance branch pipe 6, and the first spray head 61 is a 180-degree spray head.

[0057] Then the vertical maintenance branch pipe 5 is installed on the maintenance main pipe 4, and one vertical maintenance branch pipe 5 is installed every 0.5m along the length direction of the maintenance main pipe 4, and the last end position less than 0.5m can not be installed.

[0058] After the pipe sections and spray heads are all installed, it is checked whether the installation is firm and tight, and if not, it is handled in time.

[0059] Step three, install the water storage device 2; when there is no available natural water under the bent cap 01 (such as the bridge pier is arranged on the ground 02), the water storage device 2 needs to be installed, which can be a water bucket, a water tank, a water tank with sufficient volume, or a water storage structure formed by a water-proof device.

[0060] Step four, install the pump 1 and the water supply pipe 3; the pump 1 can be a submersible pump, which is put into the water storage device 2, and the water supply pipe 3 is connected with the maintenance main pipe 4 installed on the bent cap 01 in a sleeved form. The diameter of the water supply pipe 3 is 8cm-10cm, and the water supply pipe 3 can be a PE pipe.

[0061] Step five, install the controller 7, which includes a timing circuit and a switch, the controller 7 is connected with the power supply 8 on site through the wire 9, and the pump 1 is also connected with the controller 7 through the wire 9, and the whole maintenance system has been installed.

[0062] Step six, debugging; after the power supply 8 is connected, the pump 1 is turned on to observe the water head spray maintenance on the bent cap 01, and the water amount of the spray maintenance branch pipe is adjusted, the water spray range of the vertical maintenance branch pipe 5 ensures to cover the width of the bent cap 01, and the water spray of the transverse maintenance branch pipe 6 can cover most of the positions on the side of the bent cap 01.

[0063] After the water amount is adjusted through the first switch 62 and the second switch 52, observation is carried out to determine the time required for the water supply spray system to spray the whole bent cap 01, and 3min-5min is additionally added according to the time, and the increased time is the spray time of the bent cap 01 for one maintenance.

[0064] After the spray is completed, the time from wet to almost dry of the concrete of the bent cap 01 is observed, which is the maintenance interval time.

[0065] According to the spraying time of one-time maintenance and the maintenance interval time, the corresponding current supply time and interval time of the timing circuit on the controller 7 are set, so that the maintenance system is set, and the controller 7 is controlled to automatically spray and maintain the bent cap 01.

[0066] Finally, according to different weather, different environmental conditions, and different time after the completion of the pouring of the bent cap 01, the maintenance system is set to achieve more accurate maintenance and avoid insufficient maintenance of the bent cap 01 or waste of water resources.

[0067] Step seven, transfer of the maintenance system equipment. When a bent cap 01 is completed, if other bent caps 01 of a bridge need to be maintained, the maintenance main pipe 4 can be directly disassembled into 2m segments, and the transverse maintenance branch pipe 6 and the vertical maintenance branch pipe 5 and the spray heads on the branch pipes do not need to be disassembled and can be directly transferred to the bent cap 01 that needs to be maintained in segmented form, and then assembled for use.

[0068] If it is needed to be transported to other bridges for use, the maintenance branch pipes are also disassembled in sequence except for the maintenance main pipe 4, and the remaining equipment can be transferred to the position that needs to be maintained.

During the maintenance of the concrete, uninterrupted and uniform wet maintenance can be achieved, and the quality of the bent cap concrete maintenance can be well ensured.

[0070] Embodiment 2

[0071] As shown in Figure 3 The difference between the concrete bent cap maintenance construction method of the application and embodiment 1 is that in the embodiment, the pier is arranged on the water surface 03.

[0072] Because the bent cap 01 has a natural water source that can be used, the step three of embodiment 1 does not need to be performed, and the step four is directly performed after the step two, and the submersible pump is placed in the natural water source.
