Embodiment 1

[0040] see Figure 1 to Figure 3 As shown, the prefabricated sheet pile construction positioning frame 100 in this embodiment includes two rows of four steel columns 110 , two steel crossbeams 120 and one stop component 130 . Wherein, the shaped steel columns 110 are arranged vertically, and each row of shaped steel columns 110 is respectively fixed with a horizontally arranged steel crossbeam 120, and the two steel crossbeams 120 are in the same horizontal plane. The limit assembly 130 includes two steel crosspieces 131 arranged at intervals in parallel and several steel vertical pieces 132 vertically arranged between the two steel crosspieces 131. The steel vertical pieces 132 and the steel crosspieces 131 form a plurality of limit frame, the size of the limiting frame matches the size of the prefabricated sheet pile 10, and the two ends of the steel crosspiece 131 are vertically fixed on the steel crossbeam 120 respectively. As an example, the steel column 110 adopts four ...

Embodiment 2

[0046] This embodiment provides a positioning method for the construction of prefabricated sheet piles 10 using the positioning frame 100 in Embodiment 1, combining Figure 1 to Figure 3 As shown, the construction method includes the following steps:

[0047] S1. Within 30 minutes after the construction of the mixing pile is completed, drive two rows of shaped steel columns 110 vertically into the mixing pile, and fix a steel beam 120 on each row of shaped steel columns 110, and the two steel beams 120 are in the same horizontal plane. The profiled steel columns 110 can be arranged as two in each row and four in total.

[0048] S2. Prepare the limiting component 130, and fix the limiting component 130 horizontally on the steel beam 120, and make the limiting frame 133 of the limiting component 130 be located directly above the position where the prefabricated sheet pile 10 is to be constructed. The preparation method of the limit assembly 130 is to arrange two steel crosspiec...

Abstract

The invention relates to a prefabricated slab pile construction locating frame and a locating method. The prefabricated slab pile construction locating frame comprises two rows of profile steel standcolumns, two steel transverse beams and a limiting assembly, wherein the steel transverse beams are fixed to the profile steel stand columns, and the limiting assembly is fixed between the steel transverse beams. The limiting assembly comprises two steel transverse baffles and a plurality of steel vertical baffles, wherein the steel transverse baffles are arranged in a separated mode in parallel,the steel vertical baffles are perpendicularly arranged between the two steel transverse baffles, and the steel vertical baffles and the steel transverse baffles are combined to form a plurality of limiting frames in an encircling mode. The limiting assembly is fixedly arranged exactly above a prefabricated slab pile to-be-constructed region through the steel transverse beams and the profile steelstand columns, and can be used for locating a prefabricated slab pile, fixing the position of the prefabricated slab pile, guaranteeing the situation that the prefabricated slab pile is perpendicularly driven into the earth, and avoiding the phenomenon that the positional deviation of the prefabricated slab pile exists in the construction process. A construction method comprises the steps of theconstruction sequence and key points of the profile steel stand columns, the steel transverse beams, the limiting assembly and the prefabricated slab pile, and has the advantages that the working procedure is simple, operation is convenient, and assembly and disassembly of the locating frame are convenient.

Description

technical field [0001] The invention relates to a prefabricated sheet pile construction positioning frame and a positioning method, belonging to the technical field of pile foundation construction. Background technique [0002] Reinforced concrete prefabricated sheet piles (hereinafter referred to as prefabricated sheet piles) are rigid bodies, and the male and female tenons in the axis direction are anchored and connected to form an underground continuous wall. Therefore, the verticality and stability of prefabricated sheet piles are the key to construction. During the construction process, the verticality and plane position of the prefabricated sheet piles should be strictly controlled, and the prefabricated sheet piles should be sunk to the design elevation as required. [0003] Existing prefabricated sheet piles mostly use positioning piles or positioning steel for positioning. This method cannot limit or bidirectionally limit the prefabricated sheet piles, resulting in ...
