Water parks are flourishing everywhere. During holidays, there are crowds of people and laughter. The first impression of water park equipment is often the tall steel structure tracks and colorful slides. People are fascinated by their bright appearance and colors, but few people notice the inconspicuous embedded parts hidden in the concrete columns. It is these inconspicuous water park embedded parts that allow tourists to have fun, protect their lives and let everyone have fun without worries.

So what are water park embedded parts? Embedded parts are fixed or connected parts that are pre-placed during the pouring of the structure for the installation of later products (structures). Most embedded parts are made of metal. In the installation of water slide equipment, embedded parts are mainly divided into embedded parts, embedded plates and embedded sleeves (as shown in below).

As the embedded parts of the water park equipment foundation, its installation accuracy is directly related to the overall quality, safety and reliability of the entire steel structure components, and is the most critical link in the installation process of water amusement facilities. So how to ensure the installation accuracy of embedded parts? WaterBoom can be controlled from the following aspects:

Familiar with the drawings

Study coordinates

According to the condition map provided by WaterBoom, combined with the geological survey report, building, structure, etc., deepen the construction details, determine the location of the equipment unit, the relative position relationship of the embedded parts, etc. Communicate and coordinate with the civil engineering unit on the installation of embedded parts in advance to ensure the smooth construction of embedded parts. The surveying engineer is required to be very familiar with the equipment installation drawings. The accuracy and completeness of the drawings are determined by repeated verification of the equipment installation drawings and civil construction drawings.

Check coordinates

According to the coordinate information of the construction details, check with the actual situation of the on-site construction, and provide timely feedback on incorrect coordinates to avoid errors in the later construction of embedded parts due to differences in drawings, which will delay the installation progress of the subsequent main structure.

Determine the origin of coordinates

Use the coordinate origin or other position points provided on the construction details to determine the relative position relationship of all points.

Coordinate conversion

Calculate the control point coordinates (absolute coordinates) provided by the owner or convert the relative position relationship into the relative coordinates provided on the capital drawing, and ensure that each control point is closed and archived.

Calculate coordinates

According to the coordinate information in the capital drawing provided by the owner, the measurement coordinates required during the construction of embedded parts are calculated for the second time, providing a theoretical basis for the construction and re-measurement of embedded parts.

Measuring instruments

The design drawings of embedded parts of the equipment require an error of ±5mm. To ensure installation accuracy, high-precision instruments are selected.

Instrument parameters:
Angle measurement accuracy 2″
Accuracy/measurement time standard: 1.5mm + 2×10-6D / 2.4s,
Fast: 3mm + 2×10-6D / 0.8s

Control network layout

To ensure the accuracy of control points, surveying engineers need to re-arrange control based on the control points of the civil engineering unit to ensure that the accuracy of control points can meet the needs of equipment installation and keep relevant records. At the same time, do a good job of enclosure work on the control points to avoid unexpected factors that cause the displacement of control points. When construction conditions permit, the use of observation platform control can better ensure the accuracy of the control network. Surveying engineers need to conduct secondary in-depth calculations based on the coordinate information provided in the drawing by the owner to provide a theoretical basis for the construction of embedded parts and their process control.

Embedded parts assembly

Embedded parts assembly

The assembly of embedded parts directly affects the accuracy of embedded parts. During the embedded parts assembly process, each embedded part must be checked by a dedicated person in each link from assembly to transportation to the site to ensure that the center error between bolts cannot be greater than ±5mm. At the same time, in order to prevent concrete contamination during foundation pouring, the threads above the positioning plate should be wrapped with tape, and the tape or sleeve wrapped around the isolation threads below the positioning plate should ensure the length designed in the drawing.

Embedded parts positioning

During the installation process, a high-precision total station is used to ensure measurement accuracy. Coordinate accuracy requirements: X and Y coordinate errors shall not exceed ±5 mm; Z coordinate error shall not exceed ±5 mm.

The installation of embedded parts is mainly divided into three main steps: embedded parts installation, embedded parts measurement, embedded parts cleaning and finished product protection.

Before installing the embedded parts, it is necessary to review the steel cage or foundation position reserved by the civil engineering. The embedded parts can only be installed after their elevation and position meet the requirements for the installation of embedded parts.

Welding reinforcement

Make an independent steel support frame system to reinforce the embedded parts. The steel support frame system needs to be separated from the civil structure steel bars to reduce the impact on the embedded parts during the subsequent civil construction process.

Measurement of embedded parts

Positioning measurement

During the installation process, the surveyor uses the total station to monitor the position of the embedded parts throughout the process, guides the installers to position the embedded parts, and then re-measures (the first time) to ensure that the absolute position meets the X, Y axis error ≤ ± 5mm, and the Z axis error ≤ ± 5mm.

After the embedded parts are reinforced, they are re-measured (the second time) to ensure that they meet the accuracy requirements. If there is a deviation, correct it in time.

Re-measurement before pouring

After the civil engineering party completes the steel cage binding and formwork support, the embedded parts are re-measured (for the third time) and records are kept. Fill in the measurement results report before the embedded parts concrete pouring and notify the owner’s supervision. The foreign party and other relevant units conduct on-site acceptance and complete the information.

Measurement during pouring

During the pouring process, follow-up measurements should be carried out to prevent the accuracy of embedded parts from being affected during concrete pouring.

Re-measurement after pouring

Re-measure the embedded parts after concrete pouring (the fourth time) within half an hour after the concrete pouring is completed. Deviated embedded parts should be handled in time to ensure that the error of embedded parts is within the allowable range and the data is improved.

Protection of finished embedded parts

Before pouring concrete, use plastic sleeves, protective covers or tape to wrap the screw to prevent contamination of the screw during concrete pouring. After the concrete solidifies, clean the foundation and the concrete residue on the surface of the screw in time, and apply lubricating oil to the screw for rust prevention.

Through the above steps, we can well control the human error in the installation process of embedded parts, so that the installed embedded parts meet our expected requirements, create good construction conditions for the next step of steel structure installation, and ensure that the water slide equipment is installed safely, with high quality and quickly.
