An auxiliary maintenance system for installing a solid pier body, as shown in fig. 1 to 3, comprises:

the spraying device 1 is arranged on the top of the pier, and the covering is covered on the pier body;

the spraying device is supplied with water by a water supply device; the covering is composed of covering bodies 3 of different sections in the height direction; each segment of the cover body comprises two left and right segments 4. Typically, each individual height is designed to be 2-3 meters. In order to improve the wind-proof capability, the upper end of the uppermost section of the covering body is provided with a pulling rope 12, and the pulling rope pulls the upper ends of the split bodies on the two sides of the pier body tightly, so that the covering is prevented from being torn from the top end in windy weather.

The first connecting piece adopts a button or a buckle, and the left and right bodies can be connected in an auxiliary manner through double-sided adhesive tape according to actual working conditions; the second connecting piece adopts buttons, eye-splices or double-sided adhesive tapes. Namely, the periphery of each split is connected with the adjacent split through buttons, jacks or double-sided adhesive tapes, and a small-segment lap joint part 11 is reserved for the adjacent two splits as far as possible, so that a gap is avoided when the two splits are connected, and the split type wind-proof split type moisture-preserving curing device is more beneficial to moisture-preserving curing and is also more beneficial to wind-proof.

In an alternative embodiment, in order to ensure the wind resistance of the covering, a plurality of cables 5 with different heights are respectively and correspondingly arranged on the two halves of each section of the covering body, and the two ends of each cable are respectively tied with the two ends of the other corresponding cable on the other half.

The spraying device comprises an annular spraying pipeline 6 which is arranged above the pier top through a bracket, and a plurality of spray heads 7 are arranged on the spraying pipeline. The water supply device comprises a water tank 10, which is connected with a spray pipeline of the spray device through a water supply pipe 2, and a water supply pump is arranged on the water supply pipe. Usually, a high-lift water pump is selected, and the skilled person can select the high-lift water pump according to the conventional technical means. In order to realize automatic spraying, a time relay can be arranged in a control circuit of the water supply pump, interval time and duration time are set according to factors such as weather conditions, and timing and quantitative water supply can be ensured. Usually, the water tank has a volume of not less than 2m³The cylindrical water tank of the cylindrical water tank.

The water tank is placed to be close to the bridge pier as far as possible, other process operations of bridge pier construction cannot be influenced, the warning water level line is annotated in the water tank, the water tank is replenished when the water level drops to the warning water level line, and the water level of the water tank is guaranteed to meet the requirements.

The outer fringe trend of shower pipe and pier cap is unanimous, shower nozzle and pier top height difference are 10-30cm, and the shower nozzle is arranged towards pier top center lopsidedly, has improved the utilization ratio at water source when spraying, avoids water to spill in the covering outside, and the shower nozzle has a certain distance apart from the pier top interval moreover, and the water column can scatter on the concrete face during spraying, has improved the scope that the shower nozzle sprayed water and covered, has realized under the condition that sets up less shower nozzle, guarantees as far as possible that spray set's each shower nozzle evenly sprays.

In an alternative embodiment, as shown in fig. 4, a plurality of long downcomers 8 are arranged at intervals outside the pier body, and a short downcomer 9 is arranged between every two long downcomers. Normally, the lowest outlet of the long downcomer is located at 2/3 about the height of the pier body (from the top of the pier downwards), the short downcomer is located at 1/3 about the height of the pier body (from the top of the pier downwards), and the inlets at the upper ends of the long downcomer and the short downcomer are flush with or slightly lower than the top of the pier.

In the in-process of spraying the maintenance, with the help of the length that sets up, short downcomer, can be more quick with partial shower water (can be through directly adjusting the water inlet of downcomer well with partial shower nozzle, also can flow into the water in the downcomer with the help of the mound top) leading-in pier shaft middle part and well lower part fast, with pier shaft upper portion directly from the mound top down water for whole mound body humidification jointly, the covering plays the effect of keeping moisture, it is shorter when using to spray the maintenance, it is efficient, and more water conservation.

A method for maintaining a solid pier body comprises the following specific steps:

covering a layer of covering on the outer side of the pier body;

supplying water to a spraying device at the pier top by a water supply device to enable the spraying device to spray water to the pier top;
