Prefabricated guide wall and secant pile construction technology using same

Abstract

The invention relates to the technical field of building construction, and discloses a prefabricated guide wall and a secant pile construction technology using the same. The prefabricated guide wall comprises a plurality of guide wall components, the top of each guide wall component is provided with a splicing groove, the bottom surface of each guide wall component is provided with a splicing block, first mounting holes penetrating through the groove walls of the corresponding sides of each splicing groove are formed in the groove walls of the two sides of each splicing groove of each guide wall component, and second mounting holes penetrating through each splicing block are formed in the side walls of each splicing block of each guide wall component. The secant pile construction technology further comprises the following steps that a site is leveled, and pile position measurement points are placed; a guide wall groove is excavated, a pre-guide wall is installed, the center point of a pile body is remeasured, a drilling machine is centered in place, a first section of sleeve and a second section of sleeve are hoisted and placed, a reinforcement cage is hoisted and placed in the first section of sleeve and the second section of sleeve, concrete is poured, a secant pile is manufactured, the prefabricated guide wall is recycled, and earthwork backfilling is conducted. The prefabricated guide wall has the characteristics of low manufacturing cost, simple and convenient dismounting process and flexibility in use.

Description

Technical field [0001] The present invention relates to the field of building construction technology, and more particularly to a prefabricated wall and a seminar construction process using the prefabricated wall. Background technique [0002] As a new type of pile, the bite pile has achieved better results in some urban subway construction, which effectively solves the short-resistant problem of traditional double-row pile, miraculous pile and other piles, which has waterproof effect. The advantages of small environmental impact, low quality and low quality; the bite pile enclosure is a structure similar to the ground continuous wall formed by the concrete piles, which can be used as a structure of the support soil as a waterproof curtain. For the selection of the pile material, it can be reinforced concrete, or it is also used in the use of concrete and reinforced concrete, and the bite pile is characterized by mutual biting between the piles and the piles, thereby forming a wh...

Problems solved by technology

[0003] The construction process of occlusal piles is relatively complicated. The construction process mainly includes the construction of guide walls, mud preparation and treatment, fabrication and hoisting of steel cages, underwater concrete pouring, etc. Among them, the construction of guide walls is a key process to ensure the verticality of occlusal piles and the quality of piles. One; the guide wall is an indispensable structure in the construction of occlusal piles. Its main function is to protect the opening, support the load of construction equipment, and ensure the verticality of the occlusal pile casing. Most of the existing guide walls are cast-in-situ structures or The steel structure, the cast-in-place guide wall has the advantages of high rigidity and good integrity, but there are problems of high production cost, high labor intensity of workers, and it is difficult to dismantle. The steel structure has the advantages of high rigidity and good integrity. At the same time, the labor cost and labor intensity are smaller than those of cast-in-place structures, but because the cost of steel materials is much higher than that of cast-in-place structures, it does not conform to the advanced concept of green construction; therefore, it needs to be improved
