Example Embodiment

[0024] Example one:

[0025] It can be seen from the attached drawings that a non-borrowing prestressed pipe pile or prefabricated square pile sinking construction method, the steps are:

[0026] A. Pile position measurement and release: Measure and place the pile positions according to the design drawings. Each pile shall be driven into the ground with a bamboo stick with a length of 20 cm and a width of 1-1.5 cm. Paint the top of the bamboo stick exposed to the ground, and It is level with the ground surface to avoid damage or displacement when people walk or move the pile machine. For the convenience of rechecking and measuring, certain control points should be arranged according to the axis and protected by cement mortar;

[0027] B. Leading hole construction: Use SMW construction method machine or powerful deep mixing machine to carry out lead hole construction at the pile position. The depth of the lead hole is determined according to the buried depth of the sand layer, and ...

[0029] Embodiment two:

[0030] It can be seen from the attached drawings that a non-borrowing prestressed pipe pile or prefabricated square pile sinking construction method, the steps are:

[0031]A. Pile position measurement and placement: Measure and place the pile positions according to the design drawings. Each pile shall be driven into the ground with a bamboo stick with a length of 20 cm and a width of 1 cm. Paint the top of the bamboo stick exposed to the ground, and touch the ground. The surface is flat to avoid damage or displacement when people are walking. For the convenience of review and measurement, the sliding axis is used as the central axis control point every 10 to 15 meters and protected by cement mortar;

[0032] B. Leading hole construction: The deep mixing machine with high power is adopted, and P032.5 ordinary silica hydrochloric acid cement and bentonite are used as the components of the slurry. During the drilling process of the drilling rig, the slurry s...

[0035] It can be seen from the attached drawings that a non-borrowing prestressed pipe pile or prefabricated square pile sinking construction method, the steps are:

[0036] A. Pile position measurement and release: Measure and place the pile positions according to the design drawing. Each pile shall be driven into the ground with a bamboo stick with a length of 20 cm and a width of 1.5 cm. Paint on the top of the bamboo stick exposed to the ground and touch the ground. The surface is flat to avoid damage or displacement when people walk around. For the convenience of rechecking and measuring, the central axis control point is used along the axis intersection and cement mortar is used for protection;

[0037] B. Leading hole construction: The deep-seated mixing machine with large power uses P032.5 ordinary silica hydrochloric acid cement and bentonite as the components of the slurry. During the drilling process of the drilling rig, the slurry supply shou...

Abstract

The invention discloses non borrow leading hole pre-stress pipe pile or perform square type pile sinking construction method, which can ensure engineering quality, reduce construction cost, and solve the problem of sinking pile penetrating close sand layer. Its construction main point includes the following steps: adopting machine cut and stirring; stirring sera whose main component is curing agent cement and additive and soil mass; forming sera soil mixture to prevent pressing pile counterforce; with the solidification of the cement, the soil mass intensity and friction resistance around the pile are exceeded the undisturbed soil to satisfy the pile foundation bearing capacity and design demand. The invention can apply in sinking pile of the pipe pile or perform square type pile when the place has close sand layer and the sinking pile is need to penetrate sand layer. It can reduce soil squeezing effect while sinking pile, and solve the neighborhood building sinking pile construction.

Description

technical field [0001] The invention relates to a load-bearing pile for building foundations, specifically, it is used for the shallow part of the planned site where there is a relatively thick and dense sand layer, and the design of the pile foundation selects the bearing layer below the sand layer. The invention relates to a construction method for sinking prestressed pipe piles or prefabricated square piles through non-borrowing holes to solve the difficulty of passing through dense sand layers during pile construction. Background technique [0002] With the rapid development of urban construction, the land resources available for construction are becoming less and less, so housing construction is developing towards high-rise buildings, and various high-rise and super high-rise buildings have become the current construction dominance. For the foundation engineering of high-rise and ultra-high-rise buildings, the requirements for foundation bearing capacity are getting hig...
