Abstract
The utility model relates to a pile foundation structure, and provides a manual excavated pile structure, which comprises a retaining wall arranged in a previous layer, wherein a water face of the retaining wall at the previous layer section is provided with drain holes. Underground water in the previous layer flows into the pile via the drain holes, thereby reducing side pressure of soil layers onto the retaining wall due to the underground water, leading the soil layer surrounding a pile hole to be solidified, and then being favorable for supporting structures above the pile foundation via the pile foundation. Due to small side pressure on the retaining wall, stability of the retaining wall is strengthened, and safety of construction personnel in the pile hole is guaranteed effectively during construction. Further, the manual excavated pile structure is simple and fast in construction, reduces construction cost, guarantees construction safety and quality of pile products, is suitable for various pile foundations and is particularly suitable for pile caps of bridge piers.
Description
Technical field
The utility model relates to piling strtucture, especially a kind of manually digging hole pilework.
Background technology
Manual digging pile construction is convenient, speed comparatively fast, does not need heavy mechanical equipment, and hole digging pile is stronger than timber, concrete driven pile shock resistance, and the punching of cost specific impulse awl, the punching of impact awl, percussive drill punching, abrasion drill machine drill hole, open caisson foundation are saved.Thereby in highway, civilian construction, be used widely.But hole digging pile underground work condition is poor, environment is abominable, labour intensity is big, and it is particularly important that safety and quality seem.
Underground water is modal problem in the deep foundation construction, and it brings many difficulties to manual digging pile construction.Water in the pervious layer has destroyed its equilibrium state when excavation, Static Water around making charges in the hole, thereby influenced the normal construction of hand excavated pile, if run into the construction of dynamic water-pressure soil layer, not only excavation is difficult, concrete guard wall is difficult to construction molding, even is washed away by hydraulic pressure, and pile quality problem even construction safety problem take place.As run into fine sand, silty strata, under the effect of press water, quicksand and leakage phenomenon easily take place.
The utility model content
Technical problem to be solved in the utility model provides a kind of manually digging hole pilework of construction safety.
The technical scheme that its technical problem that solves the utility model adopts is: the manually digging hole pilework, comprise the retaining wall that is arranged in the pervious layer, and at the pervious layer section, the upstream face of described retaining wall is provided with spilled water hole.
Further, described spilled water hole is provided with aqueduct, and described aqueduct is extended in the pervious layer by spilled water hole, and the tube wall of described aqueduct is provided with the infiltration hole.
Further, described aqueduct is wrapped with filter membrane.
As a kind of preferred version, described filter membrane is a geotextiles.
Further, described filter membrane is wrapped with the topping that is made of wire gauze.
Further, draw water for convenience, described hand excavated pile bottom is provided with sump.
The beneficial effects of the utility model are: the underground water in the pervious layer flows in the stake by spilled water hole, thereby has alleviated because the soil layer that underground water causes to the lateral pressure of retaining wall, and makes and soil layer consolidation around the stake hole helps the support of pile foundation to structure on it.Further, aqueduct is pre-buried before retaining wall forms, and has enlarged the scope of water guide, reduces the retaining wall lateral pressure, and the consolidation soil layer helps the construction molding of retaining wall.Because the retaining wall lateral pressure is little, increase the stability of retaining wall, therefore effectively guaranteed the safety of constructor in the work progress king-pile hole.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model aqueduct.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, manually digging hole pilework of the present utility model comprises the retaining wall 1 that is arranged in the pervious layer, and at the pervious layer section, the upstream face of described retaining wall 1 is provided with spilled water hole.
Underground water in the pervious layer flows in the stake by spilled water hole, thereby has alleviated because the soil layer that underground water causes to the lateral pressure of retaining wall, and makes and soil consolidation around the stake hole helps the support of pile foundation to structure on it.Because retaining wall 1 lateral pressure is little, increase the stability of retaining wall 1, therefore effectively guaranteed the safety of constructor in the work progress king-pile hole.
Further, described spilled water hole is provided with aqueduct 2, and described aqueduct 2 is extended in the pervious layer by spilled water hole, and the tube wall of described aqueduct 2 is provided with infiltration hole 4.Aqueduct 2 is pre-buried before retaining wall 1 forms, and has enlarged the scope of water guide, reduces retaining wall 1 lateral pressure, and fixed soil layer helps the construction molding of retaining wall 1, helps guaranteeing diameter, the verticality in a hole.
Above-mentioned hand excavated pile structure construction is simple, quick, has reduced construction cost simultaneously, and safety measure has obtained guarantee, and the end product quality of stake also is guaranteed.
Because pervious layer comprises fine sand, flour sand etc. usually, stop up aqueduct in order to prevent particle, described aqueduct 2 is wrapped with filter membrane 5.
For further prevent aqueduct 2 pre-buried can be damaged after to the soil layer, described filter membrane is wrapped with the topping that is made of wire gauze 6.
Underground water in the inflow stake hole can be extracted out by directly connect water plug on spilled water hole, and the drainage effect of this mode is best, but the pipeline connection is loaded down with trivial details, and unconfined drawing water may be unfavorable for construction on the contrary.Therefore, best, described hand excavated pile bottom is provided with sump 3.Water plug has sump 3 to extract the underground water that flows in the stake hole out.
The above-mentioned mode of drawing water, aqueduct quantity, aqueduct insert the degree of depth of soil layer and all should need select and determine by practice of construction.
In the cushion cap pile driving construction of bridge pier, often run into the silty sand that alluviation forms, this soil layer water permeability is strong, and poor stability easily collapses, and runs into water and easily forms quicksand; Or the piece stone soil that forms of alluviation, this soil layer soil property pine, whole adhesion stress is little, easily strides and collapses, and easily leaks.Be particularly useful for manually digging hole pilework of the present utility model, can reach the strength stream and the loosening purpose of controlling well in fixed silty sand, the leadout hole.
