DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown,

[0025] A drainage prefabricated pile for treating soft road foundation comprises a prefabricated pile body 1, the top of the prefabricated pile body 1 is fixedly connected to a fixed top seat 2, and drainage prefabricated pile anti-blocking mechanisms 3 are arranged on both sides of the prefabricated pile body 1.

[0026] In this embodiment: Under normal circumstances, in the traditional drainage precast pile design, the drainage hole is usually directly exposed to the outside without effective protection measures. This design can easily cause mud, sand and other impurities to enter the drainage hole during the construction process, especially during the transportation and driving of the pile body into the ground. Once these impurities accumulate in the drainage hole, they will reduce the water flow capacity of the drainage hole and may even completely block the drainage hole, thereby weakening the function of the drainage precast pile and affecting the drainage efficiency and safety of the entire foundation. Furthermore, by adding the drainage precast pile anti-blocking mechanism 3, the drainage position of the pile body can be protected when the precast pile body 1 is driven into the ground to avoid blockage, thereby ensuring the subsequent drainage effect.

[0027] like Figure 1 - Figure 4 As shown,

[0028] Based on the existing prefabricated drainage piles for road soft foundation treatment, the drainage area can be sealed and protected before the pile body is driven into the ground. After the pile body is driven into the ground, the sealing structure can be pulled out, thereby avoiding blockage in the drainage area and improving the drainage efficiency and safety of the foundation.

[0029] More specifically:

[0030] In combination with the above content, in order to protect the drainage position of the pile body when the precast pile body 1 is driven into the ground to avoid blockage, thereby ensuring the subsequent drainage effect, the drainage precast pile anti-blocking mechanism 3 includes a clamping groove 31, a drainage shell 32, a drainage groove 33, a positioning component 34 and a filtering component 35. The clamping groove 31 is symmetrically arranged on both sides of the precast pile body 1, and the top of the clamping groove 31 passes through the top of the fixed top seat 2. The drainage shell 32 is slidably clamped on the inner side of the clamping groove 31, the drainage groove 33 is arranged at the bottom of one side of the drainage shell 32, the positioning component 34 is arranged in the clamping groove 31, and the filtering component 35 is arranged on the top of the fixed top seat 2.

The positioning component 34 is arranged in the clamping groove 31, and the filtering component 35 is arranged on the top of the fixed top seat 2, and then the drainage groove 33 on the drainage shell 32 can be sealed and protected by the positioning component 34, so that when the prefabricated pile body 1 is driven into the ground, the drainage groove 33 can be protected, thereby avoiding the occurrence of blockage problems. After the pile body is driven in, the positioning component 34 can be pulled out, thereby achieving the function of drainage, and the impurities in the external water can be filtered through the filtering component 35 to reduce the problem of blockage of the drainage shell 32.
