Compared with the traditional control measurement pile embedding process, this The scheme effectively solves the problem of geographical restrictions, and does not need to pour marker stones in advance, which reduces the corresponding procedures and is more practical.

Compared with the transportation of traditional control measurement piles, this scheme transforms the transportation control measurement piles into transportation of concrete materials, which reduces the difficulty and cost of transportation and provides convenience for transportation.

In addition: 1. The length of the pipeline is at least 60cm, and the length of the pipeline can be adjusted according to the level of the control point. 2. Set the thickness of the pressure surface layer to 8-15cm, and set the thickness of the cushion surface layer to 10-20cm. The pressure surface layer and the cushion surface layer in this range can cooperate with the soil to limit the pipe.

Preferred option 1: As the preferred option of the basic solution, the pipe is a PVC drainage pipe. Through the above configuration, the PVC drainage pipe is cheap, easy to construct, and has high installation efficiency.

Preferred option 2: As a preferred option of preferred option 1, the PVC drainage pipe has a diameter of 200-1000 mm, and through the above configuration, it can meet the requirements of different levels of control points.

Preferred option three: As another preferred option of the basic solution, the distance between the pressing surface layer and the cushion surface layer is 25-42cm. Through the above settings, the limiting effect of the pressure surface layer and the cushion surface layer on the soil in this range Well, the limit effect on the pipeline has been further improved.

Optimum solution 4: As another preferred solution of the basic solution, a reinforcement layer is also included, and the reinforcement layer is sleeved on the outer wall of the bedding layer. Through the above configuration, the reinforcement layer can limit and stabilize the bedding layer , to further improve the stability of the bedding layer to the pipeline limit.

Preferred Solution 5: As a preferred solution of Preferred Option 4, the cushioning layer and the reinforcement layer are integrally formed. Through the above-mentioned configuration, the structural stability of the integral formation is higher, and the stability of the cushioning layer to the pipe is further improved.

Preferred Scheme Six: As another preferred scheme of the basic scheme, the width of the press surface layer gradually increases from top to bottom, and the width of the cushion surface layer gradually decreases from top to bottom. Through the above settings, the cushion surface layer The shape of the pit is more matched and fitted to the inner wall of the pit, which increases the contact area between the cushion surface layer and the inner wall of the pit, increases the friction force, and then strengthens the position-limiting effect on the pipeline; because the cushion surface layer is used to compact the soil The surface is the bottom of the cushion surface layer, therefore, the width of the cushion surface layer gradually increases from top to bottom, which can further save material consumption and reduce costs.

Optimum option 7: As an optimal option of preferred option 6, both the pressure surface layer and the cushion surface layer are made of concrete. Through the above settings, the pressure surface layer and the cushion surface layer are all the same material as the control measuring pile, and no additional preparation is required , more convenient to use.
