Problems solved by technology

[0003] In the process of geogrid construction, the self-weight of the upper filling soil or the insertion of ordinary steel bars are generally used to anchor the geogrid, but these methods cannot effectively anchor the geogrid during the construction process, and do not meet the requirements of connecting two Lap joints between geogrids

Embodiment Construction

[0035] Such as Figure 1 to Figure 5 As shown, the geogrid soil layer anchor of the present invention includes an anchor rod 1, the anchor rod 1 is in an inverted U shape, and also includes a hammer head 2, and the hammer head 2 is arranged at the bottom of the anchor rod 1, and the anchor rod 1 is in the shape of Inverted U-shaped, which can effectively tighten the geogrid. The bottom of the hammer head 2 is designed with a sharp cone, which can make it easier for the anchor to drive into the cushion. At the same time, the tail of the hammer head 2 is a round surface, which can make drilling Anchors inserted into the bedding are more difficult to pull out.

[0036] The anchor rod 1 is made of round steel with high rigidity, which can prevent deformation when the anchor rod 1 is driven into the soil, improves the bearing capacity of the anchor rod 1, can tension the geogrid more effectively, and has a better anchoring effect.

[0037]The anchor rod 1 is set with a sleeve 3, t...

Abstract

The invention discloses a geogrid soil anchoring device and a construction method thereof. The geogrid soil anchoring device comprises an anchoring rod and a hammer-shaped head, wherein the anchoringrod is in an inverted U shape, and the hammer-shaped head is arranged at the bottom of the hammer-shaped head. The construction method comprises the following steps of: 1) laying geogrids; 2) checkingthe anchoring device and an anchoring device mounting seat; 3) fixing the anchoring device on the mounting seat; 4) anchoring the geogrids by using the anchoring device; 5) fixing all geogrids on anembankment; 6) testing the anchoring degree of the anchoring device. The anchoring device can effectively tighten the geogrids, the anchoring device is easier driven into a cushion layer, and the anchoring device driven into the cushion layer is more difficult to pull out. According to the invention, manual support of the anchoring device is not needed, and the probability of injury to the construction personnel when the anchoring device is driven into the cushion layer is reduced, meanwhile, that the anchoring device can be perpendicular to the cushion layer is ensured and the anchoring effect of the anchoring device is enhanced.

Description

technical field [0001] The invention belongs to the technical field of embankment construction, and in particular relates to a geogrid soil layer anchor and a construction method thereof. Background technique [0002] Reinforced embankment is a new type of embankment construction method, and the layout of geogrid is the focus of quality control of reinforced embankment. Sufficient tension of the geogrid during construction is crucial to the settlement control of the entire embankment and the drainage effect of the cushion. Through the arrangement of the geogrid, the settlement of the embankment can be effectively controlled, the lateral displacement of the embankment can be reduced, the drainage consolidation of the foundation and the overall stability of the embankment can be accelerated. [0003] In the process of geogrid construction, the self-weight of the upper filling soil or the insertion of ordinary steel bars are generally used to anchor the geogrid, but these meth...
