Embodiment Construction
[0062] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0063] The standard parts required for prefabricated sheet piles are all prefabricated according to modular size standards. The cross-section of prefabricated sheet piles can be divided into hollow T-shaped 1, T-shaped special-shaped 2, box-shaped rectangular 3, and double-web T-shaped 4. See figure 1 , figure 2 , image 3 , Figure 4 .
[0064] Stiff composite prefabricated sheet pile enclosure structure is mainly composed of prefabricated sheet piles 10 and soil hardener mixing body. The prefabricated sheet piles are vertically arranged in separate and continuous types, and the cross-section can be divided into hollow T-shaped 1, T-shaped special-shaped 2, box-shaped rectangle 3, double-belly T-shaped 4; the soil hardener mixing body can b...

The invention discloses a stiff composite precast sheet pile envelope structure. The stiff composite precast sheet pile envelope structure is formed by compounding precast sheet piles and a soil hardening agent stirring body, and the precast sheet piles are vertically arrayed separately and continuously; cross sections of the precast sheet piles are open-web-T-shaped, special-t-shaped, box-type-rectangle-shaped and double-web-T-shaped; when the precast sheet piles are arrayed continuously, long flanges of the precast sheet piles are in butt joint with one another; the precast sheet piles are connected by horizontal joints and vertical joints; a reinforced connecting sleeve is embedded in the top of each precast sheet pile, so that each precast sheet pile is conveniently connected with a crown beam reinforced steel bar and is anchored into a crown beam; a reinforced connecting sleeve is embedded in a supporting position of each precast sheet pile and is connected with a waist beam; and horizontal connecting joints of the precast sheet piles are in staggered-joint distribution or continuous-joint distribution among the adjacent sheet piles. The stiff composite precast sheet pile envelope structure is high in construction operability, high in component assembling degree, high in construction operation efficiency, low in construction cost and good in project implementation effect; and project materials are saved.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a foundation pit, a slope enclosure structure or a slope protection structure for water conservancy, ports and river courses. Background technique [0002] The pile row or diaphragm wall enclosure structure in foundation pit engineering or slope engineering is an important structural form and has been widely used all over the world. At present, pile rows or diaphragm walls often use bored cast-in-place columns and underground diaphragm walls etc., these are all enclosure structures poured in situ. [0003] Whether it is cast-in-situ pile or underground diaphragm wall, it is a pile formed by mechanically forming holes or grooves, mud retaining walls, forming pile holes or wall grooves in the foundation soil, placing steel cages in them, and pouring concrete on site. , Wall structure. The construction of cast-in-place piles or underground diaphragm walls with mud retain...
