Problems solved by technology

However, there are often problems such as inclination during the assembly process, resulting in uneven assembly gaps between the previous prefabricated pile and the next prefabricated pile, which affects subsequent engineering construction, especially for underground buildings, such as continuous walls. The problem of installation inclination between the piles will not only affect the subsequent assembly construction, reduce the overall structural strength, but also affect the subsequent waterproofing treatment, causing water leakage and other problems

Embodiment 1

[0031] see Figure 1-3 , a construction method of an underground diaphragm wall, the construction method comprises the following steps:

[0032] S1. Sink at least two prefabricated piles 1 into the soil in sequence according to the design requirements, and form more than one fillable reserved hole 2 in the arrangement direction between two adjacent prefabricated piles 1;

[0033] S2. Remove the debris in the reserved hole 2, so that the hole wall of the reserved hole 2 exposes the rough surface;

[0034] S3. Fill the reserved hole 2 with a cementitious material 3. After the cementitious material 3 hardens, two adjacent prefabricated piles 1 are positioned to form an overall anti-tilting structure.

[0035] Specifically, the underground diaphragm wall includes a plurality of prefabricated piles 1 that are prefabricated in the factory, and the prefabricated piles 1 can greatly shorten the construction period when prefabricated in the factory. Concrete can reduce the impact on ...

Embodiment 2

[0038] In this embodiment, the parts that are the same as in the first embodiment are given the same reference numerals, and the same text descriptions are omitted.

[0039] see Figure 1-6 , compared with Embodiment 1, the construction method of the underground diaphragm wall provided by this embodiment also has such a difference in structural design:

[0040] see Figure 2-4 , in the arrangement direction of the prefabricated piles 1, the two ends of the prefabricated piles 1 have matching concave-convex structures respectively. The two prefabricated piles 1 are limited by the cooperation of concave and convex structures, which improves the connection strength between two adjacent prefabricated piles 1 and reduces the possibility of them swinging and toppling.

[0041] Preferably, in the arrangement direction of prefabricated piles 1, see image 3 One end of the prefabricated pile 1 has a connection groove 12, and the other end has a connection protrusion 13. The connecti...

Embodiment 3

[0046] In this embodiment, the parts that are the same as those in Embodiments 1 and 2 are given the same reference numerals, and the same text descriptions are omitted.

[0047] see Figure 1-6 , with respect to embodiment one, two, the construction method of underground diaphragm wall provided by this embodiment also has such difference structural design:

[0048] Processing the reserved hole 2 in step S2 can avoid that the cementitious material 3 added to the reserved hole 2 cannot reach the expected strength after hardening, so first remove the sundries in the reserved hole 2 to avoid affecting the cementitious material 3 The strength after hardening and the connection strength between the cementitious material 3 and the prefabricated pile 1. Step S2 includes the following steps, step 2a, pretreating the sundries in the reserved holes 2, so as to prevent the sundries in the reserved holes 2 from sticking too strongly and not easy to discharge; The hole wall is cleaned to...

Abstract

The invention provides a construction method of an underground diaphragm wall. The construction method comprises the following steps of 1, sequentially sinking at least two precast piles into a soil body at preset positions according to design requirements, and forming one or above fillable reserved hole between two adjacent precast piles in the arrangement direction; 2, reserving impurities in the holes, so that enabling the hole walls of the reserved holes to be exposed out of the rough surfaces; and 3, filling the reserved holes with a cementing material, and after hardening the cementing material, positioning every two adjacent precast piles to form an overall anti-inclination structure. The reserved holes are filled with the cementing materials, so that an integrated structure is formed between every two adjacent precast piles, the precast piles are not prone to inclination, the overall structural strength of the underground diaphragm wall is improved, the cementing materials canseal gaps between every two adjacent precast piles, the cementing materials form a water stop structure between every two adjacent precast piles, and the problems of water seepage and water leakage are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of prefabricated piles, in particular to a construction method for an underground continuous wall. Background technique [0002] Currently, bored cast-in-situ piles are used for the enclosure structure. This type of pile has a high horizontal bearing capacity and mature construction technology. characteristics, and a large amount of mud will be produced during the construction process, which will have a great impact on the environment, and the bored piles are generally cast on site, the quality of the concrete fluctuates greatly, and there are serious waste of materials, large amounts of garbage, and are greatly affected by the weather. Low labor efficiency and long construction period and other disadvantages. [0003] With the continuous development of industry, the sustainable development of human beings must save resources, and then propose prefabricated piles. The prefabricated piles are produced and pr...
